Description

deep storage system

technical field

The utility model relates to an underground drainage regulating and storing waterway, in particular to a deep regulating and storing waterway system for increasing drainage and preventing water source pollution.

Background technique

In the environment where humans live, there must be a supply of fresh water to maintain basic survival and meet the needs of other human activities. The largest source of fresh water on the surface is the melted snow water from rainfall or snowfall, which is collected into streams to form rivers, or hidden underground to become groundwater, and finally accumulated to become fresh water available for human life.

As the population density increases, the development of the surface becomes more and more serious. In urban areas with high population density, due to the needs of residents' activities, a large amount of land must be used for various activities, such as commerce, transportation, social interaction, sports, etc. Therefore, a large amount of land has been paved with artificial paving (Paving), such as concrete or asphalt concrete, to provide the needs of human activities. Most of the soil under these impermeable or extremely low-permeability artificial pavements is compacted and compacted in order to be able to bear a larger load or make the soil more stable, which also results in a situation where the water permeability of the surface soil is greatly reduced.

In order to cope with this phenomenon, most of the modern society lays a large number of drainage systems in the residential area, and the rainfall that falls on the road or the land is directly discharged into the side ditch of the road, the concentrated ditch, or the drainage ditch built in the vast open space ( whether by means of open trenches, culverts or underground pipes), and then discharged into other further downstream drainage facilities or drainage mains or rivers.

However, whenever heavy rain strikes, most of the rainfall cannot penetrate into the soil to be absorbed and utilized by the land and be used as groundwater resources, but is directly discharged into artificial or natural drainage ditches. Therefore, not only water resources cannot be stored, but also floods or flooding will occur, and the mixed sewage will further reduce the living environment and quality. For the modern environment where water resources are increasingly scarce, it causes waste and pollution of precious water resources, which is really a great loss.

detailed description

Please refer to Fig. 1 and Fig. 2, which are a schematic cross-sectional structure diagram of a preferred embodiment of the deep regulation and storage waterway system of the present invention and a three-dimensional structural diagram of a shaft structure. The deep regulation and storage waterway system 1 of the present utility model is located under an excavation area 2 , and the deep regulation and storage waterway system 1 includes: at least one shaft structure 11 and at least one deep tunnel 12 . The shaft structure 11 is excavated by a submerged shaft excavation device (not shown in the figure). Of course, for the convenience of excavation, the shaft structure 11 is designed to be approximately perpendicular to the excavation area 2 . The shaft structure 11 includes: an accommodating space 111 , a ring wall 112 and a bottom body 113 . The accommodating space 111 has a cylindrical structure with a diameter D and a length L. In the present invention, the diameter D is between 4.5 meters and 40 meters, and the length L is between 20 meters and 100 meters.

The ring wall 112 is a circular tube structure, and the ring wall 112 is located on the outer surface of the accommodating space 111 , so that the accommodating space 111 is just inside the ring wall 112 . The ring wall 112 has a plurality of annular slices 1120 stacked on each other, each of the annular slices 1120 has a plurality of arc-shaped slices 1121 adjacent to each other. In a preferred embodiment of the present invention, the ring wall 112 can be completed outside the shaft structure 11 first, and then put into the accommodating space 111 , of course, it can also be directly fabricated by casting concrete in the accommodating space 111 .

The bottom cover 113 is connected to one end of the ring wall 112 and closes one end of the accommodating space 111 . When the accommodating space 111 is excavated by the sunken shaft excavation device (not shown in the figure), an approximately hemispherical curved surface shape will be formed at the bottom of the accommodating space 111, so the concrete is cast directly at the bottom of the accommodating space 111 When making the back cover 113 , that is, the back cover 113 is made of concrete material, so that one end of the back cover 113 closing the accommodating space 111 has a planar structure, and the other end has a nearly hemispherical curved structure.

The deep tunnel 12 is a circular pipe-shaped structure. In a preferred embodiment of the present invention, the deep tunnel 12 is approximately perpendicular to the shaft structure 11, and the two ends of the deep tunnel 12 are respectively connected to the shaft structure 11. The deep tunnel has an inner diameter DI, and the inner diameter DI is between 2 meters and 15 meters. Of course, the outer edge of the deep tunnel 12 also has a second ring wall 121 to strengthen the structural strength of the deep tunnel 12 .

Please refer to FIG. 3 and FIG. 4 , which are schematic block diagrams of the equipment system and process flow of the construction method of the deep storage waterway of the present invention. For the convenience of explanation, the following steps 91 to 99 correspond to the process blocks 91 to 99 in Fig. 4 respectively for the construction method of the utility model's deep storage waterway. The construction method of the utility model's deep regulation and storage waterway includes the following steps:

Step 91: Provide a deep water regulation and storage waterway construction equipment system 3 (as shown in Figure 3, combined with Figure 2), the deep water regulation and storage waterway construction equipment system 3 includes: an excavation area 2, a submerged vertical shaft driving device 31 , a submersible pump 32 , a soil and gravel debris pump 33 , a separation and sand screening device 34 , a bottom sealing body 113 , a transverse excavation device 35 , a monitor 36 , a monitoring system 37 and a plurality of annular plates 1120 . The monitoring system 37 , the separation and screening device 34 and the plurality of annular discs 1120 are located outside the excavation area 2 , while the submersible pump 32 , the soil and debris pump 33 and the monitor 36 are located in the excavation area 2 .

Step 92 : Position the sunken shaft boring device 31 on the excavation area 2 . The excavation area 2 is roughly located in a new urban planning area, or an existing improvement or development area of an old city.

Step 93: Excavate to a predetermined depth with the sinking shaft boring device 31 to form an excavation body in the excavation area 2, and the excavation body includes several soils, rocks and liquids. The predetermined depth is designed to be between 20 meters and 100 meters according to requirements, and of course, according to different depths, the sunken shaft boring device 31 forms a space with a diameter of 4.5 meters to 40 meters in the excavation area 2 .

Step 94 : Using the earth and gravel debris pump 33 to provide the excavated body to the separation and sand screening device 34 , the separation and sand screening device 34 separates the excavated body to form a mud liquid. At the same time the monitor 36 provides a remote message to the monitoring system 37 . When the sinking type shaft excavation device 31 was excavating, the soil and rocks were moved out of the excavation area 2 with the soil and gravel debris pump 33, and when the liquid began to appear, the excavated body was granularly excavated with the separation and sand screening device 34. The rock separates to form this mud liquid which is a mixed liquid of mud and sand. Use the monitor 36 to provide a remote message to the monitoring system 37 to monitor the status of the excavation area 2 at any time.

Step 95 : Use the submersible pump 32 to supply the mud liquid into the excavation area 2 . Since the water level in the excavation area 2 needs to be higher than the outside ground water table to prevent subsidence, the mud liquid is refilled into the excavation area 2 .

Step 96 : Assemble a plurality of annular pieces 1120 to the excavation area 2 until the annular wall 112 is formed. The annular piece 1120 further has a plurality of arc-shaped pieces 1121 adjacent to each other. The annular piece 1120 can be assembled outside the excavation area 2 and then sent to the excavation area 2. Of course, it can also be directly placed in the excavation area 2. Mid-cast concrete fabrication is completed.

Step 97 : Assemble the bottom cover 113 at the bottom of the excavation area 2 to form a shaft structure 11 . Since the excavation area 2 will be formed at the bottom of the excavation area 2 when the excavation area 2 is excavated by the sunken shaft excavation device 31, when the bottom of the excavation area 2 is directly poured with concrete to make the back cover 113, the bottom of the excavation area 2 will be formed. One end of the bottom cover body 113 enclosing the excavation area 2 has a planar structural shape, and the other end has an approximately hemispherical curved surface structural shape.

Step 98 : Use the submersible pump 34 to pump the mud liquid in the shaft structure 11 out of the excavation area 2 . Since the shaft structure 11 will be filled with the mud liquid when the shaft structure 11 is finished, the mud liquid needs to be extracted to the outside of the excavation area 2 , but the overall structural strength is supported by the ring wall 112 .

Step 99 : Forming at least one deep tunnel 12 on one side of the shaft structure 11 with the transverse drilling device 35 . The transverse tunneling device 35 is one of a shield tunneling device and a pipe jacking tunneling device. In a preferred embodiment of the utility model, the deep tunnel 12 is conductively connected to another shaft structure 11 .

Only the above-mentioned embodiments should not be used to limit the scope of application of the present utility model. The scope of protection of the present utility model should be based on the technical spirit defined by the content of the patent application of the present utility model and the scope included in equal changes. By. That is to say, all equal changes and modifications made according to the patent scope of the utility model will still not lose the gist of the utility model, nor depart from the spirit and scope of the utility model, so all should be regarded as further implementation of the utility model situation.
