Description

Positioning and guiding device for rectangular steel reinforcement cage of occlusive pile

Technical Field

The utility model relates to an occlusive pile construction technical field of excavation supporting specifically says a positioning guide device of occlusive pile rectangle steel reinforcement cage.

Background

With the rapid development of national economic construction, the trend of foundation pit engineering towards large-area and large-depth development is more obvious, and the surrounding environment is more inclined and complicated. The secant pile is a novel structure of the enclosure body for deep foundation pits and large-area row piles, which is suitable for the development trend. The secant pile is a supporting wall body formed by cutting and secant a later-constructed concrete pile with a circular reinforcement cage and a first-constructed concrete pile, and is also called a pile wall. The concrete pile constructed first is generally called as plain pile, and the concrete pile with round reinforcement cage constructed later is generally called as dizzy pile. In order to enhance the bending resistance and shearing resistance bearing capacity of the plain pile, technicians add rectangular reinforcement cages or square reinforcement cages in the plain pile, so that the first-construction pile is also called a first-sequence pile, and the second-construction pile is called a second-sequence pile. Shear force can be transmitted between the plain piles or the first-order piles and the dizzy piles or the second-order piles, the secant piles can effectively play a role in stopping water while retaining soil, and the secant piles are suitable for being used in areas with high underground water level, narrow fields and high environmental protection requirements.

The secant pile in the prior art generally adopts a spiral full-casing pile machine to construct a cast-in-place pile, firstly constructs a pile provided with a rectangular reinforcement cage or a rectangular reinforcement pile or a plain pile or a dizzy pile or a second-order pile, requires that the construction of the dizzy pile provided with the circular reinforcement cage or the second-order pile must be completed before the initial setting of the concrete of the plain pile provided with the rectangular reinforcement cage or the plain pile or the first-order pile, and adopts the full-casing pile machine to cut the concrete of the intersection part of the adjacent first-order piles so as to realize the secant of the two piles during the construction of the second-order pile. However, the cast-in-situ bored pile constructed by adopting the spiral full-casing pile machine in the prior art has the following defects: after the bored concrete pile is pour while drilling, when the rectangular reinforcement cage is inserted to the vibrating, the horizontal position of rectangular reinforcement cage is hardly in the central point of the horizontal plane of first preface stake puts, and rectangular reinforcement cage hardly guarantees to be in the vertical position from last to down, the straightness that hangs down promptly deviates, and the deviation is great, thus, when dizzy stake is the plain stake of second preface stake pore-forming cutting or is called first preface stake promptly, the whole sleeve pipe of the dizzy stake of construction can destroy skew plane intermediate position and the rectangular reinforcement cage that has vertical deviation, take out rectangular reinforcement cage even, seriously influence plain stake be the integrality of first preface stake, sealing performance and bending resistance, anti-shear bearing capacity.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a make rectangle steel reinforcement cage be located the central point that plain pile or called first preface stake horizontal plane basically puts, and makes the straightness deviation of hanging down of rectangle steel reinforcement cage reduce by a wide margin's secant pile rectangle steel reinforcement cage's positioning guide device.

The technical solution of the utility model is that, a positioning and guiding device of rectangular steel reinforcement cage of secant pile is provided, which comprises a rectangular sleeve pipe with inner hole shape and size matched with the cross section shape and size of the rectangular steel reinforcement cage, a rectangular horn mouth with big top and small bottom for leading in the rectangular steel reinforcement cage is arranged at the top end of the rectangular sleeve pipe, a circular cutting sleeve sleeved on the outer circumference of the top end of the whole sleeve pipe is fixedly connected on the outer wall of the rectangular horn mouth, at least one clamping block is arranged on the outer wall of the top end of the whole sleeve pipe, and at least one clamping block is clamped into the clamping block at the bottom end of the circular cutting sleeve pipe so as to limit the circular cutting sleeve pipe and the rectangular sleeve pipe circumferentially; the peripheral outer wall of the rectangular sleeve is provided with at least four sliding blocks which are in sliding fit with the circular inner wall of the full sleeve, the four sliding blocks are uniformly arranged along the circumference, and the width of each sliding block is equal, so that the distances between the outer walls of the four plates of the rectangular sleeve and the inner hole wall of the full sleeve are equal, and the rectangular sleeve is positioned at the center of the inner hole of the full sleeve.
