Intelligent control pump station and control method

Abstract

The invention discloses an intelligent control pump station and a control method. The intelligent control pump station comprises an operation screen, a control calculating system, a hydraulic power system, a display screen and a sensor. The operation screen, the display screen, the hydraulic power system and the sensor are connected with the control calculating system in a communicating manner. According to the control method of the intelligent control pump station, the sensor collects real-time axial force, temperature and displacement data of a steel support, and the control calculating system carries out data analysis on the axial force, the temperature and the displacement at the moment, uses a displacement variation value and a temperature variation value for correcting the axial force, gives out a loading or unloading specific value of the steel support, makes a loading or unloading instruction to the hydraulic power system, and enables the steel support to keep the optimum axialforce state in real time. According to the intelligent control pump station and the control method, the axial force of the steel support can be adjusted and controlled accurately in real time, and the problem that when common numerical control hydraulic equipment carries out foundation pit enclosure structure displacement control, the axial force of the steel support cannot be adjusted preciselyis solved.

Description

technical field [0001] The invention relates to the field of safe construction of foundation pits, in particular to an intelligent control pumping station for supporting axial force and a control method for foundation pit support. technical background [0002] The excavation of deep foundation pits in cities needs to protect the surrounding buildings and underground pipelines. Therefore, it is necessary to prevent the large displacement of the enclosure structure during the excavation of the foundation pit. Usually, the side walls of the foundation pit are supported in stages. The internal support is The more commonly used construction methods include concrete support and steel support. When steel supports are used for foundation pit support, numerical control hydraulic equipment can be used to maintain the axial force to achieve better displacement control of the enclosure structure. Commonly used CNC hydraulic equipment is a single-channel manual control method, each pump...
