In the daily civil engineering construction process, when the geological condition is not good and the bearing capacity of the foundation is small, the pile foundation is adopted, one pile is driven into the ground, and the weight of the building on the pile foundation is transmitted to the soil layer with high bearing capacity on the lower layer through the pile foundation. If the soil layer with high bearing capacity of the lower layer is deep, the friction force between the pile foundation and the surrounding soil can be utilized to support the weight of the upper building. After the earthwork is excavated, the pile core of the PHC tubular pile needs to be poured, but because the backfill bag is damaged, a large amount of accumulated soil is accumulated in the PHC tubular pile, the accumulated soil needs to be removed, otherwise, the pile core cannot be placed in place. Because the tubular pile internal diameter is less, the clear pipe operation mainly relies on adopting artifical drawing outward to clear up at present, and civil engineering efficiency is lower. The problem of how to effectively clean the accumulated soil in the pipe pile is a trouble of civil engineering construction teams.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: in order to overcome the defects of the prior art, the PHC pipe pile cleaning tool provided by the utility model is reasonable in structural design, can quickly clean accumulated soil in a pipe pile, reduces the labor intensity and improves the civil engineering work efficiency.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a PHC tubular pile clearance frock, includes working rod, adjustable connecting rod and helical blade assembly, the upper end of adjustable connecting rod fix on the working rod, and the axial direction of adjustable connecting rod is along the radial extension of working rod, the helical blade assembly then fix the other end tip at adjustable connecting rod, the helical blade assembly includes a plurality of helical blade, the working rod rotate the plane of formation parallel with the working face of helical blade assembly, the adjustable connecting rod outer peripheral face on still be fixed with the lug.
In the above scheme, through the cooperation of working lever, adjustable connecting rod and helical blade assembly, when using, rotate the working lever, through the transmission of adjustable connecting rod, the helical blade assembly that makes rotates and fetches earth, then takes out the helical blade assembly from the PHC tubular pile through the lug, realizes the clearance operation to the PHC tubular pile.
In order to facilitate the axial length according to different tubular pile degree of depth adjustment adjustable connecting rod, adjustable connecting rod include fixed link and regulation connecting rod, fixed link upper end fixed with the working beam, the lower extreme indent has the internal thread, regulation connecting rod upper end then have with this internal thread matched with external screw thread. The front end of the adjusting connecting rod is in threaded connection with the fixed connecting rod, and the telescopic function of the adjusting connecting rod is achieved through threaded matching, so that the effect of adjusting the length of the adjustable connecting rod is achieved. Meanwhile, the screw thread rotating direction is the same as the rotating direction of the helical blade assembly during working, the adjustable connecting rod is guaranteed to be screwed more and more tightly in the using process, and the condition that the fixed connecting rod and the adjustable connecting rod fall off cannot occur.
Furthermore, the fixed connecting rod and the working rod are both made of steel pipes, and the upper end of the fixed connecting rod is welded at the axial midpoint position of the working rod; the lifting lugs are two in number and are symmetrically distributed on the circumferential outer circular surface of the fixed connecting rod.
Furthermore, the helical blade assembly comprises three helical blades which are uniformly distributed in an annular radial manner by taking the center of the end part of the adjusting connecting rod as the center.
The PHC tubular pile cleaning tool has the advantages that the structural design is reasonable, when the tool is used, the working rod is rotated, the helical blade assembly is rotated to take soil through the adjustable connecting rod, and then the helical blade assembly is taken out of the PHC tubular pile through the lifting lug.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural diagram of the preferred embodiment of the present invention.
In the figure, the device comprises a working rod 1, a working rod 2, a fixed connecting rod 3, a lifting lug 4, an adjustable connecting rod 5 and a helical blade assembly.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
Fig. 1 shows a PHC pile cleaning tool, which is a preferred embodiment of the present invention, and includes a working rod 1, an adjustable connecting rod 4 and a helical blade assembly 5.
The upper end of the adjustable connecting rod 4 is fixed on the working rod 1, and the axial direction of the adjustable connecting rod 4 extends along the radial direction of the working rod 1. Adjustable connecting rod 4 includes fixed connection pole 2 and regulation connecting rod, and 2 upper ends of fixed connection pole are fixed with work lever 1, and the lower extreme indent has the internal thread, and regulation connecting rod upper end then has the external screw thread with this internal thread matched with. The front end of the adjusting connecting rod is in threaded connection with the fixed connecting rod 2, and the telescopic function of the adjusting connecting rod is achieved through threaded fit, so that the function of adjusting the length of the adjustable connecting rod 4 is achieved.
