Problems solved by technology

Due to the large load-bearing weight of high-rise buildings, the pipe piles have high requirements for buckling resistance, pullout resistance, and safety. Therefore, the quality of pile foundation construction is required to be high, and the prestress of concrete pipe piles must be strong. It can no longer meet the needs of safety, stability, reliability and strong prestress in the construction of high-rise buildings, and the innovation of its construction methods has attracted people's attention.

Embodiment Construction

[0005] The specific implementation of the present invention will be described in detail below in conjunction with the construction flow chart.

[0006] Given by flow chart, the present invention is realized by the following steps:

[0007] 1. Surveying and setting out: Set up control pile pre-leveling points near the piling construction area, not less than 2. The position is based on the principle of not being affected by piling (outside 40m from the operation site), and the axis control should be set at a distance from the outer wall pile. 5-10m to control the axis and elevation of the pile;

[0008] 2. The pile driver is in place: move the static pile driver to the top of the pile according to the piling sequence, and align it with the pile location, adjust the static pile driver to a level and stable position, and ensure that no tilting and movement occur during construction;

[0009] 3. Lifting prefabricated piles: the concrete strength of precast concrete piles can only ...

Abstract

The present invention relates to a construction method of a high-strength prestressed concrete pipe pile. The method can be effectively used for the requirement of the construction of the high-rise building high strength prestressed concrete pipe pile and settles the problems of safety and stability in the high-rise building. The settling technical scheme is that the piling machine is arranged after measuring and wire arranging. When the precast pile is checked, the precast pile is hoisted with the piling machine. When the pile is stable, the precast pile is executed with pressing. After pressing, the pile splicing and pile feeding are executed. When the test pile is checked to be qualified, the piling machine can be transferred for the next cycle operation. The method of the invention is advanced and scientific and has the advantages of fast construction speed, easy operation, good quality, strong strain resistance, stability, safety, no environmental pollution and tremendous economic and social benefit.

Description

1. Technical field [0001] The invention relates to the construction field, in particular to a construction method for high-strength prestressed concrete pipe piles. 2. Background technology [0002] With the rapid development of the economy and the continuous improvement and improvement of people's material life, the construction industry has developed rapidly, but with it, the construction land is becoming more and more tense or in short supply. In order to save land resources, high-rise buildings are increasing day by day. Due to the large load-bearing weight of high-rise buildings, the pipe piles have high requirements for buckling resistance, pull-out resistance, and safety. Therefore, the quality of pile foundation construction is high, and the prestress of concrete pipe piles must be strong. It has been unable to meet the needs of safety, stability, reliability and strong prestress in the construction of high-rise buildings, and the innovation of its construction metho...
