Pile foundation detection system using self-balancing method

Abstract

The invention relates to a pile foundation detection system using a self-balancing method. The pile foundation detection system comprises an upper steel bar cage, a lower steel bar cage and a load box; the load box comprises an upper bottom plate and a lower bottom plate; the periphery of the lower side of the upper bottom plate is fixedly connected with a hoarding which can abut against the upper side of the lower bottom plate under normal conditions; the peripheral surfaces of the ends where the upper steel bar cage and the lower steel bar cage close to each other are fixedly connected with steel rings; a steel sleeve is arranged on the outer side of the load box, the lower end of the steel sleeve is fixedly connected to the steel ring of the lower steel bar cage, and the upper end of the steel sleeve is slidably connected to the steel sleeve of the upper steel bar cage; a filling cavity is formed between the steel sleeve and the two steel rings as well as the steel sleeve and the hoarding; and the upper side of the steel sleeve is further fixedly connected with a plurality of filling tubes which can extend out of the upper end of the upper steel bar cage and communicate with the filling cavity. The pile foundation detection system using the self-balancing method has the effects that broken piles after measurement can be effectively bonded, so that the upper pile part and the lower pile pat can be integrated into a whole so as to improve the bearing capacity of the broken piles, and the subsequent measurement and use are convenient.

Description

Technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a self-balancing method pile foundation detection system. Background technique [0002] According to the existing verifiable file records, the method for testing the bearing characteristics of the pile foundation with the pre-embedded loading equipment in the pile known as the "self-balancing method" in China. According to patent information, this method is called "a new method of bearing capacity test", commonly known as "Tongmo Static Load Method". Different from the traditional stacking method, this technology places a load box shaped according to the requirements of the pile bearing capacity parameters at the bottom of the pile body during the construction process, connects the pressure oil pipe and the displacement measuring device to the top of the pile, and waits for the concrete to be cured to the standard After the age, the bottom load box is pressurized...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a self-balancing pile foundation detection system, which can solve the problem of broken piles after the self-balancing method is used to detect the bearing capacity of the pile foundation in the prior art, and can ensure the safety and accuracy of the pile foundation measurement. Effectively bond the broken pile after measurement, so that the upper pile and the lower pile can be integrated into a whole, so as to improve the bearing capacity of the broken pile and facilitate subsequent measurement and use
