Embodiment 1

[0043] In a typical implementation of the present application, such as figure 1 As shown, a verticality guide device based on the permanent support structure prefabricated pipe pile is provided, the guide device includes a guide frame 1, the guide frame 1 is arranged on the top of the crown beam 2, and the bottom of the guide frame 1 is set for the prefabricated pipe pile Through the positioning hole, a track is provided on the lower surface of the bottom of the guide frame 1 so that the guide frame 1 can move relative to the track. The positioning hole 4 in the guide device is aligned up and down with the reserved through hole on the crown beam 2. After the prefabricated pipe pile is fixed through the positioning hole 4 and the reserved through hole through the crown beam 2, the pile is driven by the piling mechanism. Compared with the traditional The piling method is faster and the construction is more convenient. In addition, multiple guide frames 1 can be set at the same t...

Embodiment 2

[0053] The construction method of the permanent support structure of the foundation pit, the specific steps are as follows:

[0054] 1) The crown beam is positioned and poured, and through holes are reserved on the crown beam for the passage of prefabricated pipe piles; The pile position requires precise positioning;

[0055] 2) The verticality guide device based on the permanent support structure prefabricated pipe pile is set at the through hole of the crown beam, and the positioning hole of the verticality guide device cooperates with the through hole to fix the prefabricated pipe pile;

[0056] 3) Remove the above-mentioned verticality guide device, seal the through hole of the crown beam, and use fine stone concrete one grade higher than the crown beam structure for the sealing and pouring.

[0057] In said step 2), a method for setting the verticality guide device based on the permanent support structure prefabricated pipe pile is as follows:

[0058] 2-1) A guide fram...

Abstract

The invention discloses a perpendicularity guide device and method based on a permanent support structure precast tubular pile. Through the perpendicularity guide device and method based on the permanent support structure precast tubular pile, the problem that in the prior art, a guide structure for a precast tubular piles is complex is solved, and guiding is convenient. According to the technical scheme, the perpendicularity guide device and method based on the permanent support structure precast tubular pile comprises at least one guide frame arranged at the top of a top beam; the bottom of the guide frame is provided with a locating hole, and the precast tubular pile penetrates through the locating hole; a rail is arranged on the lower surface of the bottom of the guide frame, so that the guide frame moves relative to the rail; the two sides of the lower surface of the guide frame are each provided with a framework perpendicular to the lower surface of the guide frame; and the frameworks are provided with open holes are fixed to a rail fixed plate through the open holes.

Description

technical field [0001] The invention relates to a prefabricated pipe pile, in particular to a verticality guiding device and method for a prefabricated pipe pile based on a permanent support structure. Background technique [0002] In the existing pipe pile construction, before the construction of the crown and beam, the traditional prefabricated pile guide device is used in the construction process. This device is a large-scale guide frame that needs to be combined with machinery. The utilization rate of this device is low, and the guiding function is not strong. In the permanent support structure, prefabricated pipe piles are different from the original support piles in that they do not have high requirements for pile verticality and axis positioning. It needs to be used as the outer wall of the underground structure, and the stability and positioning requirements are high. Therefore, Higher requirements are placed on the guiding device. [0003] Therefore, the present in...
