Construction method of self-balancing method pile foundation bearing capacity test device

Abstract

The invention discloses a construction method of a self-balancing method pile foundation bearing capacity test device, which is characterized by comprising the following processes of: 1, construction preparation: calculating a balance point position of self-balancing method pile measurement, determining the number of the pile measurement, drilling holes, cleaning the holes and detecting the verticality of the holes; 2, manufacturing a load box and welding the load box with a reinforcement cage; 3, mounting the reinforcement cage; 4, cleaning the holes again; 5, pouring concrete; and 6, carrying out self-balancing method detection. As the detection is directly carried out on engineering piles in some projects, in order to preventing the pile foundations from affecting the use, a grouting machine is used for filling gaps separated from pipelines and the load box with grout after the detection; therefore, the method also comprises the following process of: 7, carrying out pipeline grouting and reinforcement. According to the invention, the defects that the load box mounting time is long, the reinforcement cage floats upwards, the mud at the bottom of the load box is too thick, the pile foundations have gaps at the load box to influence the quality of the pile foundations, the construction progress is slow, and the like are overcome, and the pile foundations have good integrity.

Description

technical field [0001] The invention relates to a construction method of a self-balancing pile foundation bearing test device. Background technique [0002] At present, the common method of installing the self-balancing pile foundation bearing capacity test device is that it takes a long time to install the load box, and the steel cage is easy to float when pouring underwater concrete. Due to the influence of the concentration of the mud and the sedimentation speed, the mud at the bottom of the load box is too thick Especially when engineering piles are used for testing, the quality of the bridge is seriously affected and the construction progress is slow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method of a self-balancing pile foundation bearing capacity test device to solve the problems in the prior art such as long time for installing the load box, floating of the steel cage, too thick mu...
