Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a construction engineering foundation pile stability detection device. Background Art

[0002] Construction engineering usually refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. The pile foundation is a deep foundation composed of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation. When the pile foundation is in use, its stability needs to be tested. In the prior art, the announcement number CN220468948U discloses a green building pile foundation load force detection device, which detects the load force of the pile foundation to ensure the stability of the pile foundation in the subsequent use process. When in use, after the gantry is placed on the top of the pile foundation, the screw rod is rotated to push the arc side plate to move, so that the arc side plate is close to both sides of the pile foundation, thereby fixing the gantry on the pile foundation. In order to ensure the stability of the device during operation, the clamping force of the arc side plate on the pile foundation should meet the installation requirements, but it is difficult to accurately control the clamping force of the arc side plate on the pile foundation by manually twisting the screw rod. If the clamping force of the arc side plate on the pile foundation does not meet the installation requirements, the stability of the device during operation will be affected to a certain extent.
