Background
The foundation pit supporting secant pile is a continuous pile wall enclosure structure formed by mutually interlocking and lapping a plain pile (a plain concrete pile) and a meat pile (a reinforced concrete pile), has the functions of retaining soil and stopping water, and has good supporting and stopping effects.
In the prior art, in actual supporting design and construction, a rotary excavating hard occlusion construction process is generally adopted to form an occlusion pile. The rotary excavating hard occlusion construction is that after two spaced vegetable piles are firstly completed, a cutting occlusion part between the two vegetable piles is drilled to form a meat pile hole, a reinforcement cage is hung in the meat pile hole, and concrete is poured to form the meat pile.
By adopting the construction method, when a meat pile hole is formed by drilling, the vegetable pile concrete is firstly cut by adopting the drilling barrel, and then the rotary drilling bucket is replaced for dredging the slag until the required meat pile hole is formed.
When a meat pile hole is drilled, hard cutting of plain pile concrete is needed, so that drilling time is long, a drilling tool needs to be frequently replaced, the drilling efficiency is influenced to a certain extent, moreover, when the meat pile hole is drilled, the meat pile hole is influenced by the strength difference of the plain pile concrete on two sides, so that the meat pile hole is easy to deflect to a certain extent when drilled, and when the excavation depth of a foundation pit supported by an occlusive pile is more than 15m, occlusion and forking are easy to cause at the bottom of the foundation pit, so that leakage among piles is caused; in addition, the cut concrete becomes drilling slag to be discharged, thereby causing the waste of concrete materials and increasing the outward transportation amount of the waste slag.
At present, in order to solve the problems, after a plain pile hole is drilled, after a concrete is poured to form a plain pile, empty occlusion areas are hopefully formed on two sides of the plain pile, and when a meat pile is formed subsequently, the phenomenon of hard cutting of concrete cannot occur due to the fact that concrete does not exist in the occlusion areas.
After the plain pile hole is formed, a filling structure can be formed on the side edge of the plain pile hole, and when concrete is poured subsequently, due to the limitation of the filling structure, after the concrete is initially set, the filling structure is pulled out, so that a vacant occlusion structure is formed, but the filling structure is difficult to drop, so that a vacant occlusion area cannot be formed on the formed plain pile.
