Concrete pouring control system and method for cast-in-place pile

Abstract

The invention relates to the field of cement buildings, and aims to provide a concrete pouring control system and method for a cast-in-place pile. The system comprises a guide pipe for cement filling and a lifting device connected with the guide pipe, wherein the lifting device operates through a motor and drives a cable to lift the guide pipe to rise; a pressure sensor is arranged at the bottom, in a certain height position, of the guide pipe, and the pressure difference is sensed in the height position and is converted into a signal which is transmitted to an external control host machine to be processed so as to control the time and the speed for lifting the guide pipe by the motor. According to the system and method, the quality control is carried out in the pile foundation concrete pouring process to remarkably improve the pouring quality, so that the conscientious work is changed to the transparent work which can be constantly monitored and controlled, and the construction is brought into a standardized and normalized track, thereby saving a great amount of material cost.

Description

technical field [0001] The invention relates to the field of cement construction, in particular to a concrete pouring control system and method for cast-in-situ piles. Background technique [0002] Bored piles are widely used in high-rise buildings, heavy factory buildings, bridges, ports, and docks because they can transfer the upper load to deep and stable soil layers or rocks, thereby reducing foundation settlement and uneven settlement of buildings. and water conservancy projects. In these projects, due to the high requirements for the foundation, the quality of the foundation will directly affect the safety of the superstructure. [0003] At present, the construction of pouring pile concrete in China (in most cases is pouring under water) usually adopts the conduit method for construction. The principle is to pass the concrete mixture through the sealed steel pipe (or high strength steel pipe) under a certain pressure difference. The hard non-metallic pipe) entrance, ...

AI Technical Summary

Problems solved by technology

[0005] As mentioned above, it is very important to control the quality of the concrete pouring process in order to pour high-quality pile foundations. However, because the pouring process is completed underground or under the water surface, the monitoring equipment and methods currently used are very simple and extensive. The amount of concrete falling from the hopper can also be roughly estimated by rope, visual inspection, hand feeling, and sound. In a very extensive state, it brings great uncertainty to the quality of the project, so some people in the industry vividly compare the pouring of pile foundation concrete to "conscience work"
