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

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] refer to figure 1 , is a self-balancing pile foundation detection system disclosed in the present invention, comprising an upper reinforcement cage 1, a lower reinforcement cage 2 and a load box 3, and the load box 3 is placed between the upper reinforcement cage 1 and the lower reinforcement cage 2.
[0033] The ends of the upper reinforcement cage 1 and the lower reinforcement cage 2 that are close to each other are fixedly connected with the connecting ring 4, and the ends of the upper reinforcement cage 1 and the lower reinforcement cage 2 that are close to each other are also welded with horn bars 41, and the shrinking ends of the horn bars 41 are connected to each other. Close to and respectively welded to the corresponding connecting rings 4 . The trumpet rib 41 includes a number of oblique steel bars 411 whose upper ends are affixed to the upp...

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 pile foundation detection system. Background technique [0002] According to the existing verifiable archives and records, the method of testing the bearing characteristics of pile foundations by pre-embedded loading equipment in piles is called "self-balancing method" in China. According to the patent information, this method is called "a new test method for bearing capacity", commonly known as "Tongmo static load method". Different from the traditional pile-loading method, this technology is to place the load box shaped according to the requirements of the pile bearing capacity parameters at the bottom of the pile body during the construction process, connect the pressure oil pipe and the displacement measuring device to the top of the pile, and wait until the concrete is cured to the standard. After ageing, pressurize the load box at the ...
