Device for detecting bearing capacity of pile-soil composite foundation

Abstract

The invention discloses a device for detecting bearing capacity of a pile-soil composite foundation and relates to the technical field of detection devices. According to the technical scheme, the device is characterized by comprising two longitudinal bearing supports, a horizontal bearing support, multiple mounting holes, pressure sensors, movable blocks, pressure bearing blocks and data analysisrecorders, wherein a loading mechanism is arranged on one sides of the longitudinal bearing supports and comprises a rack, a loading frame, two chains rotationally connected to two sides of the loading frame and a drive assembly which is mounted on the loading frame and used for driving the two chains to rotate simultaneously; multiple stop blocks are arranged on the two parallel chains; a guide assembly used for guiding force applying pieces is arranged on the loading frame; a stop assembly used for blocking the force applying pieces is arranged between the loading frame and the longitudinalbearing supports. The problem of intense collision between the force applying pieces and the horizontal bearing support is solved, and the force applying pieces can be placed on the horizontal bearingsupport gently.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a device for detecting the bearing capacity of pile-soil composite foundations. Background technique [0002] In the subgrade design of high-grade highways, for some special soil sections such as the section close to the reservoir and humus soil, the bearing capacity of the subgrade cannot meet the requirements of the design service life of the highway. Therefore, it is necessary to set up bored piles, prefabricated concrete piles, lime-soil compaction piles, vibrating gravel piles and other forms of reinforcements at a certain distance in the subgrade to form a pile-soil composite foundation to improve the subgrade. The purpose of the overall carrying capacity. [0003] The prior art can refer to the Chinese utility model patent whose authorized announcement number is CN207525792U, which discloses a device for detecting the bearing capacity of pile-soil composite foun...

Problems solved by technology

[0004] However, when placing the force applying member on the lateral load-bearing bracket, sometimes the method of placing the force-applying member by the operator is not accurate, so the force applying member may collide violently with the lateral load-bearing bracket, which will cause the pressure sensor to be damaged to a certain extent. Degree of damage, which will affect the measurement accuracy of the pressure sensor
