Building pile foundation hole digging and coring device

Abstract

The invention discloses a building pile foundation hole digging and coring device. The building pile foundation hole digging and coring device comprises a building foundation and a device bottom plate, wherein universal wheels are separately movably mounted on the portions, which are close to the building foundation, of the two sides of the lower end of the device bottom plate; a device vertical rod is fixedly mounted at the upper end of the device bottom plate; a lifting control cabinet is arranged above one end of the device vertical rod; a hydraulic lifting rod is arranged at the lower endof the lifting control cabinet; a coring barrel is fixedly mounted on the lower surface of the hydraulic lifting rod; a diamond drill bit is fixedly mounted at the lower end of the coring barrel; a drill bit through groove is formed in the position, which is close to the diamond drill bit, of one side of the inner surface of the device bottom plate; a supporting plate is arranged above the other end of the device vertical rod; a hydraulic motor is arranged at the upper end of the supporting plate; and a support is fixedly mounted on the portion, which is close to the supporting plate, of one side of the upper end of the device bottom plate. The building pile foundation hole digging and coring device is simple in structure, a core sample can be fixed, the circumstance that the core sample is damaged in a coring process is avoided, and the drill bit during drilling can be cooled.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a hole-digging and coring device for building pile foundations. Background technique [0002] The bridge pile foundation project plays a role in stabilizing the foundation in highway construction. Since the pile foundation is an underground concealed project, it is very important to check the quality of the pile foundation. The core device detects the pile core, which can judge whether the integrity of the pile body, concrete strength, pile length, pile bottom sedimentation, and bearing layer properties can meet the requirements of the design and specifications. There are certain disadvantages in the use of the device. It is difficult to place the drilling rig equipment to maintain a level. When the drilling rig is unstable and digs holes, the drilling rig is prone to shaking and displacement, which affects the quality of the core sample and reduces the service life...
