Description
Technical Field
The utility model relates to a building structure technical field specifically is a prevent that underground building structure from extending connection position seepage structure.
Background
With the expansion and transformation of cities, the original underground facilities cannot meet the requirements. In order to improve the functions of urban infrastructure, a great number of new interconnection underground passage projects are arranged between underground passage and underground comprehensive pipe gallery extension and transformation projects and commercial building seats. Because of above engineering belongs to the later stage and adds the project, the project does not reserve the later stage in the design and extends the connector in earlier stage, and the connection position between newly-increased engineering and the former project does not have special structure measure, causes the connection position of underground passage and high-rise building underground garage, the extension connection position of underground passage and underground pipe gallery to become the weak link of structural strength, and under concrete shrink and creep, structure differential settlement etc. long-term effect, the fracture seepage phenomenon has appeared to different extents, has seriously influenced the service function of engineering.
If leakage occurs, two construction methods are mainly adopted, wherein the first method is to dig out the earthwork on the upper part of the underground structure and increase the waterproof layer again, and the second method is to drill holes on the back surface of the structure and inject grout for plugging leakage. The construction methods are labor-consuming and labor-consuming, and influence the appearance quality of the structure; therefore, the existing use requirements are not satisfied.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent that underground building structure from extending connection position seepage structure to solve the problem among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent that underground building structure extends connection position structure that leaks, includes concrete covering, concrete base, slip casting pipe and metal clamp, the concrete covering has been pour to concrete base upper surface, be provided with metal clamp and slip casting pipe between concrete base and the concrete covering, and the slip casting pipe is located the inboard of metal clamp, fix through the metal clamp between concrete base and the slip casting pipe and be connected, the metal clamp passes through fastening screw and concrete base fixed connection.
Preferably, the periphery of the grouting pipe is provided with one-way pore channels.
Preferably, the inner diameter of the unidirectional channels is 35 μm.
Preferably, the outer wall of the grouting pipe is in contact with the upper surface of the concrete base layer.
Preferably, the distance between every two adjacent metal clips is 25 cm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses pre-buried the slip casting pipe in advance between concrete cover layer and concrete base, can follow the structure crack development condition and do not leak not slip casting, the purpose of multiple seepage multiple slip casting leaking stoppage has been avoided excavating upper portion backfill and repairing waterproof layer or the structure outside intensive drilling slip casting operation, the practicality is strong, thereby has solved the difficult problem of restoreing of fracture seepage that appears between current concrete base and the concrete cover layer; through the setting of one-way pore canal, the grouting hole is opened under the grouting pressure in the grouting pipe, and the grouting hole is automatically closed after the grouting pressure is cancelled, so that external grouting liquid and formation water can be prevented from infiltrating into the grouting pipe, and the grouting pressure is ensured not to be lost.
