The cast-in-situ bored pile is one produced through mechanical drilling and other measures in engineering site to form pile hole in foundation soil, setting reinforcing cage inside the pile hole and casting concrete. In the construction process of the cast-in-situ bored pile, the prefabricated steel reinforcement structure is called a steel reinforcement cage. Because the compressive strength of the concrete is high but the tensile strength is low, the reinforcement cage mainly plays a role in tensile strength, so that the pile body concrete can bear axial tensile force.

In the construction engineering of the cast-in-situ bored pile, after a pile casing is buried, a drill can drill holes in a rotating mode when the drill is in place, then a reinforcement cage is placed after the holes are checked and cleaned, and then a guide pipe, secondary hole cleaning and concrete pouring are sequentially carried out. And (3) putting the reinforcement cage in a vertical and smooth state and ensuring that the deviation between the center of the reinforcement cage and the pile position is within the range of the specification requirement. In the prior art, more than 2 hoisting points are often utilized when the reinforcement cage is hoisted, and the center position of the reinforcement cage is controlled through the protective cylinder when the reinforcement cage is placed downwards.

But among the prior art, owing to with the pile position condition such as the complete alignment, hoist and mount operation have mistake, wind-force interference not completely, the steel reinforcement cage often meets and hinders when transferring the steel reinforcement cage, leads to not being conform to the standard with the pile position deviation, needs just reverse rotation, slowly rises slowly and falls, promotes repeatedly and transfers, the efficiency of construction is low. Meanwhile, the hole wall is easily extruded or scratched in the process of lowering and lifting the reinforcement cage, and secondary hole collapse can be caused in severe cases.

Technical problem to be solved

Aiming at the defects of the prior art, the utility model provides the centering position adjuster for vertically mounting the reinforcement cage, and solves the problems that the reinforcement cage is often blocked when being transferred, the deviation of the reinforcement cage and a pile position does not accord with the standard, the construction efficiency is low, the quality of a hole wall cannot be ensured, and the reinforcement cage is easy to fail.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme: a vertical installation centering position adjuster for a bored concrete pile reinforcement cage comprises a first base, a second base, a semicircular first bracket, a semicircular second bracket and more than three jacks, wherein the first bracket is fixed on the first base, the second bracket is fixed on the second base, the first bracket and the second bracket are spliced into a circle, the reinforcement cage can stretch into the circle, grooves are formed in inner rings of the first bracket and the second bracket, and the jacks are placed in the grooves and can move along the grooves.

The adjuster further comprises a protective sleeve, a first clamping strap and a second clamping strap are fixed on the outer side of an opening of the protective sleeve, a first limiting block is fixed below the first base, a second limiting block is fixed below the second base, the first limiting block is clamped by the first clamping strap, and the second limiting block is clamped by the second clamping strap.

The adjuster is also provided with a position adjusting wheel and a position adjusting rod, the position adjusting wheel can move along the grooves of the first bracket and the second bracket, and the center of the position adjusting wheel is fixedly connected with one end of the position adjusting rod.

(III) advantageous effects

Compared with the prior art, the utility model provides a vertical installation centering position adjuster for a cast-in-place pile reinforcement cage, which has the following beneficial effects:

the adjuster can be assembled and disassembled, the first base and the second base are spliced before the steel reinforcement cage is placed, the base and the protective cylinder are fixed through the clamp and the limiting block, the first bracket and the second bracket form a circle, and the steel reinforcement cage is lifted up to stretch into the protective cylinder through the circle. When the pile position is deviated or the reinforcement cage is blocked, the position of the reinforcement cage needs to be adjusted, the position adjusting rod is pushed at the moment, the position adjusting rod pushes the position adjusting wheel, the position adjusting wheel pushes the jack to a proper position in the groove, the jack is operated to jack the reinforcement cage to adjust the position of the reinforcement cage, the reinforcement cage continues to be placed, therefore, vertical centering is achieved, and the adjuster is detached after the reinforcement cage is placed.

The problem of when transferring the steel reinforcement cage often meet and hinder, be not conform to the standard with stake position deviation, need positive and negative rotation, slow-speed play falls slowly, and a lot of is progressively transferred, leads to the efficiency of construction low to transfer the easy failure of steel reinforcement cage is solved.
