Abstract
A waterproof sealing sleeve construction process for a ground source heat pump buried pipe penetrating a large bottom plate of a building mainly includes utilizing a waterproof sleeve and relevant components. A water stop steel plate or a water stop wing ring outside a steel sleeve pipe is compactly welded on the steel sleeve and welded on a steel reinforcing bar of the large bottom plate. The water stop plate is casted by the concrete, and rising of underground water is effectively prevented, a rubber water stop ring in the steel sleeve is tensioned and limited by a movable joint without deformation, and water is guaranteed to be stopped from entering the water stop ring. A movable joint component is tightly connected with the steel sleeve in a screw manner to prevent possible water leakage, and ejection out and falling off of waterproof materials under pressure are avoided as well. Waterproof sludge is pulled in front of the water stop ring and a water-ward surface of the sleeve, so that the sleeve can be sealed more tightly under pressure of the underground water. Screw threads can be screwed off directly on a backwater side, a sealing ring can be replaced or the waterproof sludge for sealing can be replenished, so that the sleeve can be maintained easily. The waterproof sealing sleeve construction process guarantees the buried pipe to be capable of penetrating the large bottom plate, is capable of adapting to sedimentation of the building within a certain range, and drawn breakage of the buried HDPE (high-density polyethylene) pipe due to the sedimentation is avoided, and infiltration of the underground water can be effectively separated.
Description
Technical field
This technology belongs to the underground pipe construction technology field of earth-source hot-pump system.
Energy-conservation and the renewable energy utilization system that earth-source hot-pump system is encouraged as country, in down town and building dense region can be difficult to carry out because implementing the building periphery lack of space of underground pipe, therefore, some engineering project can be considered can before large construction of bottom plates, complete at the concrete of building the construction of underground pipe before architecture construction, and hopefully pipe laying can both guarantee self not to be compromised overall structure performance and the water resistance that also guarantees the large base plate of building.
Background technology
Conventionally under large base plate during the pipe laying of construction ground, conventional construction method is after underground pipe is constructed in foundation ditch, packet combining is linked horizontal tube, and horizontal tube is drawn by the side under large base plate, under foundation ditch, go out retaining wall place common steel sleeve is set, and turn between retaining wall and gravity dam and be incorporated into equipment machine room, and at the equipment machine room jacket pipe of setting up defences.Such construction, is easy to the fracture of spot pipe laying when building settlement.And because underground pipe divides into groups, at this moment, if any one ground buried via hole causes because constructing leaking accidentally, whole group, so that pipe laying cannot be used more, even cause the failure of earth-source hot-pump system.
The steel sleeve that conventional method arranges, in fact in use cannot provide underground pipe to adapt to the naturally flexible of building settlement, the infiltration of the underground water that is also difficult to avoid pressure between underground pipe and sleeve pipe.
Owing to there is no rational arrangement and method for construction, be difficult to guarantee that underground pipe realized hermetic waterproof when passing through floors, and be also easy to cause underground pipe cannot digest building settlement in floor, thereby cause underground pipe to destroy.
And according to the construction technology of conventional water string, be difficult to guarantee the infiltration in sleeve pipe, be also difficult to guarantee underground pipe stretching in sleeve pipe.
Because common vertical tube is to be extensively distributed under large base plate, therefore most scientific rational method is to guarantee that the total length in the buried loop of each group is balanced as far as possible.But due to the water string that underground pipe is worn large base plate that is exclusively used in without suitable, therefore, in Practical Project construction, be difficult to implement the arrangement and method for construction that ground source heat pump imbedded pipe is worn large base plate on directly.
Just because of above reason, heating and ventilation project teacher and structural engineer oppose that the underground pipe of earth source heat pump is implemented under large base plate conventionally, and this has also caused finally cannot implementing earth-source hot-pump system.
Therefore in order to advance more effectively, more widely the enforcement of earth-source hot-pump system, it is a kind of more reasonable, simple in construction, can to invent, and can take into account and guarantee underground pipe free-extension and effectively prevent construction technology measure and the sleeve pipe of the Groundwater infiltration of pressure in sleeve pipe, be highly significant.
Summary of the invention
Ground buried pipe of ground source heat pump is worn the water string construction technology of the large base plate of building
This technique mainly consists of water string and associated component.
Normally the external diameter of pipe laying is that D32mm(can have multiple caliber) high density polyethylene (HDPE) plastic conduit (HDPE), need the large base plate of passing through building.The object of the construction technology of our invention is: guarantee that underground pipe can pass through large base plate, and can adapt to the sedimentation of the building of certain limit, therefore sedimentation does not cause buried HDPE pipe to be pulled off; Effectively cut off the infiltration of basement.
Take D32mmHDPE pipe as example, we select the steel pipe of DN40, and comprise by formations such as articulation, watertight rubber sealing rings, and Socket welding are connected on to steel plate for sealing water (or on water-proof wing-ring) in construction.
