Concrete cast-in-place pile top elevation control device and using method thereof

Abstract

The invention provides a concrete pouring pile top elevation control device and a using method of the concrete cast-in-place pile top elevation control device and belongs to the technical field of building engineering. The device comprises a bracket, a tension induction switch, a winder, a winding motor, a first fixed pulley, a second fixed pulley, a traction rope with scales, an alarm device anda buoyancy detection hammer, wherein the bracket comprises a bracket body and a transverse cantilever; the tension sensing switch is installed on a frame body, and the end portion of the tension sensing switch faces downwards and is equipped with the first fixed pulley; the second fixed pulley is arranged on the end portion, extending out of the frame body, of the transverse cantilever; the traction rope is wound on the winder and led out from the winder, sequentially passes through the first fixed pulley and the second fixed pulley and is connected with the buoyancy detection hammer; and thebuoyancy detection hammer is hollow, high-density substances can be loaded or unloaded to control the quality of the buoyancy detection hammer, so that the buoyancy detection hammer can be used in different construction sites. By means of the concrete pouring pile top elevation control device and the using method of the concrete cast-in-place pile top elevation control device, an interface betweena concrete layer and a laitance layer can be identified effectively, errors caused by traditional manual measurement are avoided, and the control precision of a concrete cast-in-place pile is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a control device for the top elevation of concrete pouring piles and a method for using the same. Background technique [0002] The cast-in-place pile is directly drilled on the designed pile position, and its cross-section is circular. After the hole is formed, a steel cage is placed in the hole and concrete is poured. Since cast-in-situ piles have the advantages of no vibration, no soil compaction, low noise, and are suitable for use in densely built urban areas during construction, cast-in-place pile foundation engineering has been widely used in high-rise buildings, bridges, and port wharves. It has become the most important form of basic engineering in engineering construction. However, the pile top elevation control of concrete pouring piles has always been one of the difficulties in the construction of concrete pouring piles. If the fall is too large or ...

Problems solved by technology

However, this method relies on the operator's feel or experience to judge whether the concrete exerts buoyancy on the measuring hammer, which has high requirements for the operator, and cannot guarantee that the measuring hammer is accurately located at the design elevation of the cast-in-place pile, so the identification error of the interface At the same time, due to the complex environment of the construction site, these methods are greatly affected by the working environment of the construction site, which further reduces the recognition accuracy
