Embodiment Construction

[0021] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0022] Please refer to Figure 1 to Figure 6 , the concrete cast-in-place pile reinforcement cage anti-floating method of the embodiment of the present invention, its technological process is:

[0023] Step a), before starting to drill, take the center of the pile position as the center, and determine the position of the casing on the soil according to the radius of the casing of the reinforced cage anti-floating device of the concrete pouring pile. After the casing is in place, apply pressure to move the casing The cylinder is buried in the soil, and then the drilling is started;

[0024] Step b), after the concrete pouring pile is formed into a hole, put the reinforcement cage 7 into the hole, the lock buckle passes through the installation hole 5 on the casing and connects with the connecting sleeve rod 3 through the bolt 6, a...

Abstract

The invention relates to an anti-floating method and device for a bored concrete pile reinforcement cage. The anti-floating method is characterized in that the technological process is as follows: before starting to drill a hole, taking the center of a pile position as the center of a circle, confirming the position of a steel pile casing on the soil according to the radius of the steel pile casing of the anti-floating device of the bored concrete pile reinforcement cage, after placing the steel pile casing, applying pressure for embedding the steel pile casing into the soil, and then starting to drill the hole; after forming the hole in a bored concrete pile, placing the reinforcement cage into the hole; penetrating a U-shaped lock catch into the reserved hole in the steel pile casing; using a bolt to connect the U-shaped lock catch with a connecting loop bar; inserting the tail part of a fork rod into the connecting loop bar; clamping the head of the fork rod on a top hoop of the reinforcement cage, and then starting to pour concrete; when the concrete is about to be poured to the pile top position, detaching the bolt on the U-shaped lock catch; taking down the connecting loop bar, the steel fork rod and the U-shaped lock catch; continuing pouring the concrete to the designed elevation, and pulling out the steel pile casing. According to the anti-floating method and device provided by the invention, the floating of the reinforcement cage while pouring the concrete can be effectively avoided.

Description

technical field [0001] The invention relates to an anti-floating method and a device for a reinforced cage of a concrete pouring pile. Background technique [0002] In the pile foundation construction of construction engineering, small-diameter bored piles (400mm ~ 800mm), during the pouring process, due to the light weight of the steel cage, the friction between the concrete and the steel cage produces huge anti-friction force and other reaction forces to make the steel cage float quickly. , seriously affecting the quality of the project. The existing technical scheme is to suppress or slow down the filling speed with heavy objects to prevent the steel cage from rebounding and floating. It has the following disadvantages: the weight is not well controlled, and the perfusion time is too long, which may cause catheter blockage or other accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and ...
