Embodiment Construction

[0017] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as Figure 1-3 As shown, a prefabricated hollow pipe pile rectification method, the general hollow pipe pile has two sections, this device is aimed at correcting the deviation of two prefabricated hollow pipe piles, which specifically includes the following steps: Step 1, in two adjacent hollow pipe piles A metal pin 2 is inserted between the piles 1 to connect the two hollow pipe piles into a whole; this step is a necessary step, if a metal pin is not inserted in the subsequent steps, the upper hollow pipe pile will move as a whole , completely break away from the hollow pipe pile of the bottom, for this reason, through testing, design a metal pin, the outer diameter of metal pin is slightly smaller than the inner diameter of hollow pipe pile, has certain weight, and the top of metal pin is connected...

Abstract

The invention relates to the technical field of buildings, in particular to a prefabricated hollow pipe pile deviation correcting method. The method comprises the following steps that 1, a metal pin is inserted between the two adjacent hollow pipe piles, and the two hollow pipe piles are connected into a whole; 2, the front end of a vibration hammer abuts against the lowest end of the upper part of the hollow pipe piles, the vibration hammer slowly vibrates, so that the hollow pipe piles are vertical; 3, a cushion block is placed on the upper part of the hollow pipe piles, the vibration hammervibrates the hollow pipe piles through the cushion block, so that the soil between the two adjacent hollow pipe piles is discharged; 4, the metal pin is taken out; and 5, steel bars and concrete areplaced in the hollow pipe piles, and the hollow pipe piles are sealed. According to the method, the inclined hollow pipe piles can be corrected, the adopted equipment is the traditional equipment, theconstruction cost can be greatly saved, the efficiency is very high, and the problem that the existing hollow pipe piles cannot be corrected is effectively solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a deviation correction method for prefabricated hollow pipe piles. Background technique [0002] With the development of construction technology, the field of pile foundation construction is changing with each passing day. Prestressed high-strength concrete pipe piles have many advantages such as fast construction speed, low price, high bearing capacity, stable quality, short maintenance time, convenient construction and pollution-free construction. In recent years, it has been widely used in foundation projects in various places, especially municipal soft soil foundations and collapsible foundations. In addition to ordinary concrete pipe piles in China, hollow pipe piles have appeared in order to save costs. The hollow pipe piles are composed of two sections, and there will be a certain inclination between the two pipe sections. At present, the state stipulates that the in...
