Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete cast-in-place piles for ultra-deep foundation pit reinforcement, and specifically to a reinforced concrete cast-in-place pile for ultra-deep foundation pit reinforcement. Background Technique

[0002] Reinforced concrete cast-in-place piles are widely used in high-rise building structures, soft foundation structures, and deep foundation pit support structure systems, mostly as end-bearing piles, friction piles, friction end-bearing piles, and end-bearing friction piles; at present, the construction technology of bored cast-in-place piles has been widely applied to the field of building construction. The construction process of dry-method bored cast-in-place piles is: measuring the pile position → drilling → clearing the hole → lowering the steel reinforcement cage → pouring concrete.

[0003] However, in the prior art, when the steel reinforcement cage is placed in the ground pile and then concrete is poured, the steel reinforcement cage is easily collided by the concrete and tilted to a certain extent, resulting in the axis deviation of the cast concrete pile and a significant reduction in the tensile strength.

[0004] Therefore, we provide a reinforced concrete cast-in-place pile for ultra-deep foundation pit reinforcement to solve the problem that the steel reinforcement cage in the prior art is easily collided by the concrete and tilted to a certain extent. Content of the Utility Model

[0005] The purpose of the utility model is to provide a reinforced concrete cast-in-place pile for ultra-deep foundation pit reinforcement to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a fixing plate, a steel reinforcement cage is arranged in the middle of the fixing plate, multiple groups of hinge shafts are arranged on both sides of the steel reinforcement cage, and a stabilizing plate is connected to the hinge shafts; and a ground pile is opened at the bottom of the ground main body.

[0007] Preferably, the steel reinforcement cage can be inserted into the ground pile opened at the bottom of the ground main body, and the fixing plate at the top of the steel reinforcement cage is located on the top surface of the ground pile.

[0008] Preferably, screw rods are arranged on the outer sides of the four weeks of the fixing plate, and support plates are arranged at the bottoms of the screw rods. By respectively screwing the screw rods, the support plates can be telescoped according to the height difference of the ground around the top of the ground pile, so that the steel reinforcement cage in the middle of the fixing plate is perpendicular to the ground pile.

[0009] Preferably, fixing rivets are arranged at the bottoms of the support plates, and the fixing rivets can be inserted into the soil around the top of the ground pile to fix the steel reinforcement cage in the middle of the fixing plate and prevent the steel reinforcement cage from shaking during pouring.

[0010] Preferably, the fixing plate is provided with extra-long screws on both sides of the steel cage, and the bottom of the extra-long screws is simultaneously slidably connected to multiple sets of stabilizing plates. By rotating the extra-long screws, the extra-long screws can drive the hinge shaft to press the stabilizing plates downward through rotation, so that the stabilizing plates are held against the inner wall of the ground pile, and the steel cage is clamped in the middle of the ground pile.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model proposes a reinforced concrete bored pile for reinforcing an ultra-deep foundation pit. First, the steel cage is placed in the ground pile opened at the bottom of the ground body. Then, the screws are screwed according to the height difference of the ground at the top of the ground body. The screws drive the support plate to expand and contract, and the fixing plate is horizontal. The steel cage in the middle of the fixing plate is parallel to the ground pile. Then, the fixing plate is pressed to insert the fixing rivets at the bottom of the support plate into the ground soil, and the fixing plate is fixed to prevent it from shaking during pouring. Then, two sets of extra-long screws are screwed at the same time. The extra-long screws descend through rotation, driving the stabilizing plate slidingly connected to the extra-long screws to be pressed downward by the hinged axis, so that the stabilizing plate is supported on the inner wall of the ground pile, and the steel cage inside the stabilizing plate is fixed to the middle of the ground pile to prevent it from tilting during pouring.
