Description

Prefabricated common pipe trench

technical field

The utility model relates to a pipe ditch used for pipeline installation, in particular to a prefabricated and assembled common pipe ditch.

Background technique

At present, with the rapid development of urban infrastructure construction, underground pipelines have entered a period of continuous transformation and renewal. People intuitively see that the frequent excavation of the original direct buried pipelines on the road will cause traffic jams, environmental damage, etc. question. As an intensive and sustainable pipeline laying method, the common trench provides a feasible solution to the above contradictions. On the one hand, it facilitates the maintenance and renewal of the pipeline, avoids repeated excavation of urban roads and various problems caused by it, on the other hand, it also improves the service life of the pipeline and avoids the erosion of various chemical components in the soil resulting durability issues. At present, the construction of common pipe trenches in China is open excavation and cast-in-place concrete, which brings problems such as long construction period, difficult control of construction quality, high construction cost and high maintenance requirements for foundation pits during construction. To a certain extent, the further popularization and application of the common pipe trench in the country is limited.

Contents of the invention

Aiming at the problems existing in the above-mentioned prior art, the purpose of this utility model is to provide a prefabricated and assembled common pipe trench, which can effectively improve the construction quality, speed up the construction speed, reduce the construction cost and relax the maintenance requirements of the foundation pit, and has good structural performance .

The technical scheme of the utility model is: a prefabricated and assembled common pipe ditch, including a pipe ditch segment composed of a top cover segment and a base segment that cooperate with each other, and the top cover segment and the base segment are passed through prestressed ribs and The anchorage is connected, and there is also a partition in the section of the trench. The partition is perpendicular to the cross section of the section of the trench, and divides the interior of the section of the trench into compartments that do not communicate with each other. Adjacent pipes The ditch segments are also connected by prestressed tendons and anchors, and expansion waterstops are installed at each assembled joint for sealing.

Preferably, a hoisting hole is also provided at the top of the roof segment.

Preferably, the swelling waterstop is made of water-absorbing swelling polymer material.

Preferably, the water-absorbing swellable polymer material is a polyether polyurethane swellable material.

The beneficial effects of the utility model are: adopting the prefabricated assembled structure, thereby effectively improving the building quality, speeding up the construction speed, reducing the construction cost and relaxing the maintenance requirements of the foundation pit, and having good structural performance. With partitions, different pipelines can be installed in different compartments to avoid interference; the hoisting holes in the top cover section are convenient for hoisting during installation and disassembly; the expansion waterstop at the assembly joint is made of shape memory polymer material Made to ensure good performance.

Detailed ways

As an embodiment of the present utility model, as shown in Figure 1 and Figure 2, a prefabricated and assembled common pipe ditch includes a pipe ditch segment composed of a top cover segment 1 and a base segment 2 that cooperate with each other, the The top cover segment 1 and the base segment 2 are connected by prestressed tendons and anchors, the top of the top cover segment 1 is provided with a hoisting hole 3, and a partition 4 is also provided in the pipe trench segment. The partition plate 4 is perpendicular to the cross-section of the pipe ditch segment, and separates the interior of the pipe ditch segment into compartments that are not connected to each other. In this embodiment, the partition plate 4 is divided into upper and lower parts and connected to the top cover segment 1 and The base segment 2 is connected into one body, the upper and lower parts of the partition 4 are connected together by prestressed tendons and anchors, and the adjacent trench segments are also connected by prestressed tendons and anchors. Seams are provided with expansion waterstops 5 for sealing, and the expansion waterstops 5 are made of water-absorbing swelling polymer materials. Preferably, the water-absorbing swellable polymer material is a polyether polyurethane swellable material.
