Abstract
The invention discloses a construction method for a large deep foundation pit support during encountering of a waste civil air defense. During encountering of the waste civil air defense in construction of a grouting pile of the foundation pit support, an inlet of the waste civil air defense is found first, underground water in the waste civil air defense is pumped completely, and the position of the constructed grouting pile is measured in a locating mode; a hole is drilled in the top of the waste civil air defense, the located position of the constructed grouting pile is led into the ground of the waste civil air defense, and in the position, 300 mm away from the pile edge of the grouting pile, a square brick wall is built to the top face of the waste civil air defense; then C15 fine aggregate concrete is poured into the brick wall square to the top face of the waste civil air defense; and after the C15 fine aggregate concrete is finally set, drilling grouting pile construction are constructed. Compared with a traditional method that after a waste civil air defense is removed, compact filling is constructed again, and then a drilling grouting pile is constructed, according to the construction method for the large deep foundation pit support during encountering of the waste civil air defense, the construction period is shortened, the cost is reduced, and the surrounding environment is not influenced.
Description
Technical field
The present invention relates to Large Scale Deep Foundation Pit Support and meet waste and old people's air defense construction method, belong to civil engineering foundation pit supporting construction field.
Background technology
Along with developing rapidly of urban construction, high-rise, high-rise building gets more and more, therewith, large deep foundation pit engineering is the most increasing, Large Scale Deep Foundation Pit Support is typically mainly constructed plus prestressed anchor or concrete inner supporting structure with cast-in-situ bored pile, during supporting construction, also complicated landform and the barrier of left over by history can be run into, such as, the waste and old civil air defense constructions and installations in past, elongated when running into waste and old people's air defense and other barriers in work progress, it is all to abolish the mode tamped, but, waste and old people's air defense is in underground, full subsoil water can be amassed for a long time, it is particularly at position, city proper, abolish and can affect neighbouring town road, the problems such as neighboring buildings and corresponding environment.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, Large Scale Deep Foundation Pit Support is provided to meet waste and old people's air defense construction method, mainly solve cast-in-situ bored pile meet the hole such as waste and old people's air defense cannot the situation of pore-forming, the method is safe and reliable, do not affect surrounding enviroment, and duration, cost-effective can be accelerated.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
Large Scale Deep Foundation Pit Support of the present invention meets waste and old people's air defense construction method, when pattern foundation pit supporting structure filling pile construction runs into waste and old people's air defense, first find waste and old people's air defense entrance, subsoil water inside it is exhausted, the bored concrete pile position of construction is measured in location, a hole is bored at waste and old people's air defense top, it is located position and is incorporated into waste and old people's air defense ground, away from the 300mm of grout pile limit, build square brick wall by laying bricks or stones to waste and old people's air defense end face, C15 pea gravel concreten extremely waste and old people's air defense end face is poured into again in brick wall square, after treating that C15 pea gravel concreten reaches final set, then bored pile construction.
As a preferred technical solution of the present invention, one 600 × 600mm hole is bored at described waste and old people's air defense top.
As a preferred technical solution of the present invention, described in build 500mm thickness brick wall by laying bricks or stones.
The present invention is reached to provide the benefit that: this Large Scale Deep Foundation Pit Support meets waste and old people's air defense construction method, than traditional abolish waste and old people's air defense after tamp construction drill bored concrete pile again from newly, the reduction of erection time, reduce cost, and do not affect surrounding enviroment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Embodiment 1
As Figure 1-3, Large Scale Deep Foundation Pit Support disclosed by the invention meets waste and old people's air defense construction method, when pattern foundation pit supporting structure filling pile construction runs into waste and old people's air defense 1, first find waste and old people's air defense 1 entrance, subsoil water inside it is exhausted, bored concrete pile 4 position of construction is measured in location, a hole is bored at waste and old people's air defense 1 top, it is located position and is incorporated into waste and old people's air defense 1 ground, away from 4 from bored concrete pile limit 300mm, build square brick wall by laying bricks or stones to waste and old people's air defense 1 end face, C15 pea gravel concreten 3 is poured into again to waste and old people's air defense 1 end face in brick wall square, after treating that C15 pea gravel concreten 3 reaches final set, cast-in-situ bored pile 4 is constructed again, one 600 × 600mm hole 5 is bored at described waste and old people's air defense 1 top, described build 500mm thickness brick wall 2 by laying bricks or stones.
Concrete: when pattern foundation pit supporting structure bored concrete pile 4 construction runs into waste and old people's air defense 1, first find waste and old people's air defense 1 entrance, subsoil water inside it is exhausted, bored concrete pile 4 position of construction is measured in location, 600 × 600mm hole 5 is bored at waste and old people's air defense 1 top, it is located position and is incorporated into waste and old people's air defense 1 ground, away from 4 from bored concrete pile limit 300mm, build 500mm thickness brick wall 2(square respectively by laying bricks or stones) to waste and old people's air defense 1 end face, making 4 limits of bored concrete pile is 300mm from building brick clear spacing by laying bricks or stones, in brick wall square, pour into C15 microlith coagulation 3 soil again tamp to waste and old people's air defense 1 end face, after treating that C15 microlith coagulation 3 soil reaches final set, cast-in-situ bored pile 4 is constructed again, thus solve the waste and old people's air defense 1 of chance and cannot construct.
The present invention than traditional abolish waste and old people's air defense 1 after tamp, from newly, bored concrete pile 4 of constructing again, the reduction of erection time, reduce cost, strengthen quality and safety, and do not affect periphery town road, building and relevant environment etc., successful implementation in Engineering Projects.
