Abstract

The invention provides a grouting pipe pile and a construction method of the grouting pipe pile. The grouting pipe pile includes: a cover plate, a connecting mechanism, a plurality of grouting pipes, and a water-permeable inner pipe and an outer pipe; the outer pipe is used to be placed in the pile hole; the inner pipe is sleeved inside the outer pipe, and, There is a preset distance between the inner pipe and the outer pipe; each grouting pipe is placed between the outer pipe and the inner pipe, each grouting pipe is connected to the inner pipe through a connecting mechanism, and each grouting pipe is connected to the pile hole The end that is in contact with the bottom of the hole is a closed end, and the wall of each grouting pipe is provided with an opening to inject grout into the space between the inner pipe and the outer pipe; the cover plate is set on the top of the outer pipe, and the cover A first through hole is opened on the plate corresponding to the inner pipe and a second through hole is opened corresponding to each grouting pipe. The invention effectively ensures the stability of the surrounding foundation, ensures the stability of the pile body, effectively controls the thickness of the reinforcement protective layer, combines precipitation and foundation treatment, facilitates the control of grouting amount, and makes the pipe pile compact and stable.

Description

technical field [0001] The invention relates to the technical field of pipe pile construction, in particular to a grouting pipe pile and a construction method for the grouting pipe pile. Background technique [0002] When carrying out foundation treatment and precipitation construction in the sandbar area, there are many fine silts in the sand and high water level. Due to the poor filtering effect of the precipitation well, the surrounding area often collapses. Precipitation in the structural range brings the danger of hollowing out the foundation, and the cost of precipitation and foundation treatment is relatively high. Therefore, cement mixing piles, reinforced concrete piles and gravel piles are often used for foundation treatment of sandbars. [0003] For the treatment of large-scale foundations that require precipitation, flower pipe piles are often used. However, due to the high content of silt in the sand, the effect of flower pipe piles on filtering sand is poor. ...
