Description
Technical Field
The invention relates to a building construction device, in particular to a pile core soil taking-free device for a prefabricated hollow pipe pile.
Background
When the prefabricated hollow pipe pile is constructed, the pile body is sent into a soil layer by hammering the pile end. After the pile is driven, the hole at the end of the hollow prefabricated pipe pile is exposed outside. Mud and rainwater enter the pile core through the pile end hole and often plug the pile core. Before the pile head is cut and the pile core reinforcement cage is placed, sundries such as pile core soil need to be manually dug. This is time consuming, labor intensive, and slow to construct. About 30 yuan is required for digging the soil of one pile core. Tens of thousands of piles, which costs tens of thousands of yuan.
To solve this problem and save the cost, a device capable of preventing earth and sand water from entering the column core is needed.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a pile core soil taking-free device for a prefabricated hollow pipe pile, aiming at the defects of the prior art.
The technical scheme is as follows: the invention discloses a pile core soil taking-free device for a prefabricated hollow pipe pile, which comprises a soil retaining device covering a hollow pipe pile hole, wherein the soil retaining device comprises a soil retaining cover plate and a clamping limiting device fixedly connected to the soil retaining cover plate, and the clamping limiting device is clamped and matched with the hollow pipe pile hole.
Preferably, the retaining cover plate is a steel circular cover plate, and the diameter of the steel circular cover plate is larger than that of the hollow pipe pile hole.
Preferably, the diameter of the steel circular cover plate is 25mm larger than that of the hollow pipe pile hole.
Preferably, the clamping limiting device is at least two clamping legs welded on one side, facing the hollow pipe, of the steel circular cover plate.
Preferably, the number of the clamping legs is 3, and the three clamping legs are arranged in an equilateral triangle.
Preferably, the clamping legs are 50mm long and 12mm in diameter, and the distance from each clamping leg to the center point of the steel circular cover plate is 10mm smaller than the radius of the hollow pipe pile hole.
Preferably, the clamping leg is made of HRB 400.
The utility model discloses following beneficial effect has: compared with the prior art, the method has the following advantages: can effectively protect hollow pipe pile for mud can not pour into in the hollow pipe pile hole, can avoid drawing and dig stake core soil, improve the efficiency of construction, reduce construction cost.

Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
The utility model provides a prefabricated hollow tubular pile exempts from to draw native device of stake core, keeps off native device including covering the fender soil device on the hollow tube stake hole, keeps off the soil device including keeping off native apron and fixed connection joint stop device on keeping off native apron, joint stop device and hollow tube stake hole joint cooperation. Compared with the prior art, the method has the following advantages: can effectively protect hollow pipe pile for mud can not pour into in the hollow pipe pile hole, can avoid drawing and dig stake core soil, improve the efficiency of construction, reduce construction cost.
The retaining cover plate is a circular steel cover plate 1, and the diameter of the circular steel cover plate 1 is larger than that of the hollow pipe pile hole. The diameter of the steel round cover plate 1 is 25mm larger than that of the hollow pipe pile hole. The diameter of the steel round cover plate 1 is 25mm larger than that of the hollow pipe pile hole, so that tight covering can be guaranteed.
The clamping limiting device is at least two clamping legs 2 welded on one side, facing the hollow pipe, of the steel round cover plate 1. The number of the clamping legs 2 is 3, and the three clamping legs 2 are arranged in an equilateral triangle. The length of each clamping leg 2 is 50mm, the diameter of each clamping leg is 12mm, and the distance between each clamping leg 2 and the central point of the steel circular cover plate 1 is 10mm smaller than the radius of the hollow pipe pile hole. The clamping leg 2 is a HRB400 clamping leg 2. The diameter of the clamping legs 2 is 12mm, the distance between each clamping leg 2 and the central point of the steel circular cover plate 1 is 10mm smaller than the radius of the hollow pipe pile hole, 1mm of overflow between the side surface of the clamping leg 2 and the hollow pipe pile hole can be guaranteed, and the stable clamping can be guaranteed.
Example (b): when the construction of the prefabricated hollow pipe pile is completed, the hole at the end of the hollow prefabricated pipe pile is exposed outside; the device is opposite to a pile end hole, 3 clamping legs 2 are placed into the pile hole, and a steel circular cover plate 1 covers the pile hole to seal the pile hole; preventing mud from being poured into the pile core; when the pile core is constructed, the cover device is opened to lift the steel circular cover plate 1 to carry out pile core steel bar installation and concrete pouring; the device is recovered and enters the next flow section for construction.
As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
