CFG pile driver quality monitoring system

Abstract

The invention discloses a CFG pile driver quality monitoring system which comprises a horizontal chassis. Bosses are arranged on two sides of the horizontal chassis, hydraulic supporting legs are installed on the bosses, a supporting frame is installed at one end of the horizontal chassis through a hinge base, a hydraulic telescopic rod and a reinforcing connection rod are connected between the supporting frame and the horizontal chassis through hinges, the reinforcing connection rod is located on the upper side of the hydraulic telescopic rod, and a first motor is installed in the middle of the horizontal chassis. The CFG pile driver quality monitoring system conducts accurate positioning on a construction site by controlling an RTK attitude instrument receiver in a box, prevents the problem that a deviation exists between a construction position and an actual position, makes the horizontal chassis always kept in a horizontal state by detecting a state of the horizontal chassis through a level gauge, detects the loosing degree of a steel rope based on current change of a first ampere meter, accordingly controls the sinking speed of a drill rod, reduces noise and shake in the construction process, improves pile forming quality and detects the rotating speed of the drill rod based on the current change of a second ampere meter.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a CFG pile driver quality monitoring system. Background technique [0002] In road engineering, the treatment of soft soil foundation is the key link to ensure the quality of the project, and it occupies a relatively large proportion of the total project price. A large number of engineering practices have shown that the cement-soil mixing pile method has the advantages of simple construction, rapid construction, and small vibration. To improve the stability of soft soil foundation, reduce and control the settlement, cement-soil mixing pile has now developed into a commonly used soft foundation treatment method, mainly suitable for the reinforcement of saturated soft clay foundation, this method is to use cement (or lime, etc. ) material as a curing agent, through a special mixing machine, the soft soil and the curing agent are forced to stir on the spot deep in the ...

[0002] In road engineering, the treatment of soft soil foundation is the key link to ensure the quality of the project, and it occupies a relatively large proportion of the total project price. A large number of engineering practices have shown that the cement-soil mixing pile method has the advantages of simple construction, rapid construction, and small vibration. To improve the stability of soft soil foundation, reduce and control the settlement, cement-soil mixing pile has now developed into a commonly used soft foundation treatment method, mainly suitable for the reinforcement of saturated soft clay foundation, this method is to use cement (or lime, etc. ) material as a curing agent, through a special mixing machine, the soft soil and the curing agent are forced to stir on the spot deep in the foundation, and a series of physical and chemical reactions occur between the curing agent and the soft soil, making the soft soil harden into A cement-soil mixing pile with integrity, water stability and certain strength. This cement-soil mixing pile forms a composite foundation together with the soil around the pile, thereby improving the bearing capacity of the foundation and reducing foundation settlement. The existing CFG pile driver quality monitoring system is for The position of the drilled pile, the amount of material used, the degree of slack of the steel rope, and the horizontal state of the horizontal chassis are measured, resulting in a deviation between the construction position and the actual position, resulting in waste of materials, and the inability to detect the amount of material used affects the quality of the pile. , for this reason, we propose a CFG pile driver quality monitoring system
