Description

Technical Field

[0001] The utility model relates to the technical field of load boxes, in particular to a fixing structure of a load box for pile foundation self-balancing detection. Background Art

[0002] The principle of pile foundation self-balancing detection is to bury a special loading device load box in the corresponding position of the pile together with the steel cage before pouring concrete, lead the pressure pipe of the loading box and other required test devices from the pile body to the ground, and then pour the pile. A pressure pump is used to pressurize the load box on the ground, so that a loading force is generated inside the pile body. By calculating and analyzing the relationship between the loading force and these parameters, we can not only obtain the bearing capacity of the pile foundation, but also obtain a series of data such as the lateral resistance coefficient of each soil layer, the lateral resistance of the pile, and the pile end bearing capacity. This method can be used to provide data basis for design, and can also be used for the detection of engineering pile bearing capacity.

[0003] Load box - As the name implies, in the early stage of pile foundation testing, it is necessary to specify the corresponding load box suitable for the test in advance according to a series of data such as the specific tonnage of the pile, pile foundation, hole depth, etc., and weld the load box and the steel cage together before pouring concrete on the pile, and finally bury them together in the corresponding position of the pile and pour concrete. However, during the construction process, since the load box needs to be welded and fixed to the steel cage, and the number of steel bars welded to the edge of the load box is generally more than 20, as the diameter of the pile foundation increases, the number of steel bars that need to be welded will increase linearly. Each steel bar will produce a weld point between the edge of the load box, which is very dependent on the welding quality at the weld point. However, the welding level of the workers is different, which will lead to uneven welding quality at the weld point, thus affecting the test results. For this reason, we propose a fixed structure of a load box for pile foundation self-balancing detection to solve the above problems. Utility Model Content
