Abstract
The utility model discloses a drilling secant pile has solved under unfavorable geological conditions, and the bored concrete pile that prior art adopted has mud overflow to cause the influence to the surrounding environment to the construction site occupies greatly, and the construction period is long, technical problem with high costs. The retaining wall comprises a pile A and a pile B, wherein the pile A and the pile B are arranged at intervals to form a row of retaining walls, the pile B is arranged between every two adjacent pile A, and each pile B is meshed with the adjacent pile A. The horizontal cross section of the pile A is the same as that of the pile B. The utility model discloses having realized the segmentation construction purpose to subway deep basal pit enclosure, having overcome the interference that cross construction brought, reduced occuping of construction site, practiced thrift the construction cost.
Description
Technical field
The utility model relates to a kind of space enclosing structure stake of Metro Deep Excavation.
Background technology
In the subway foundation pit civil engineering process of soft soil layer,, all can cause very big influence, even cause the sedimentation of ground high-rise building surrounding environment if the retaining of space enclosing structure soil and stagnant water effect are bad.Prior art generally is the method that adopts bored pile piling under unfavorable geological condition, and the defective that the used mud off of castinplace pile exists mud to overflow surrounding environment is impacted, and the construction plant takies greatly, and is long in time limit, the cost height.
Summary of the invention
The utility model provides a kind of boring interlock stake to solve under unfavorable geological condition, and the castinplace pile that prior art adopted exists mud to overflow surrounding environment is impacted, and the construction plant takies greatly, and is long in time limit, the technical problem that cost is high.
The utility model overcomes the above problems by following scheme:
A kind of boring interlock stake comprises A stake and B stake, it is characterized in that, A stake and B stake are arranged to a row formula retaining wall at interval, is provided with the B stake between per two adjacent A stakes, and each B stake all is interlocked with adjacent A stake.
Level cross-sectionn in described A stake is identical with the level cross-sectionn of B stake.
The utility model has been realized the section construction purpose to the subway Extra-Deep Foundation Pit, has overcome the interference that crossed construction brings, and has reduced taking of construction plant, has saved the construction funds.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a construction flow chart of the present utility model
Specific embodiment
A kind of boring interlock stake comprises A stake and B stake, it is characterized in that, A stake and B stake are arranged to a row formula retaining wall at interval, is provided with the B stake between per two adjacent A stakes, and each B stake all is interlocked with adjacent A stake.
Level cross-sectionn in described A stake is identical with the level cross-sectionn of B stake.
The all casing drill drilling construction is adopted in boring interlock stake, forms the foundation pit enclosure structure that mutual interlock is arranged between stake and stake.The arrangement mode of stake is that A stake and B stake are arranged at interval, construction B stake after the construction A stake earlier during construction, and require must finish before the super slow setting concrete initial set of A stake the construction of B stake.Adopt all casing drill to cut away the plain concrete of adjacent A stake intersection during the B pile driving construction, thereby realize interlock.
With the reinforced concrete pile is example, the construction technology process of single pile is led wall → drill machine with casing centering in place → lifting as: smooth place → measurement stake position → construction concrete and is laid first segment sleeve pipe → observing and controlling verticality → be pressed into first segment sleeve pipe → check and correction verticality → grab bucket to fetch earth, advance → measure hole depth → removing loosened soil with pipe bit, at the bottom of the inspection eye → B stake install reinforcing cage → put into concrete pouring conduit → perfusion concrete to pull out sleeve pipe → mensuration concrete face → stake machine displacement one by one.A type single pile construction technology and Type B pile foundation are originally identical, just do not have this operation of install reinforcing cage.
Claims (2)
1. a boring interlock stake comprises A stake and B stake, it is characterized in that A stake and B stake are arranged to a row formula retaining wall at interval, is provided with the B stake between per two adjacent A stakes, and each B stake all is interlocked with adjacent A stake.
2. a kind of boring interlock stake according to claim 1 is characterized in that, and is identical with the level cross-sectionn of B stake in the level cross-sectionn of described A stake.
