The Construction Method of Concrete Filling Conduit Control Device for Pile Foundation

Abstract

The invention relates to a construction method of a control device for concrete pouring conduits in pile foundations. Each section of conduit is placed on a shaped support, and the shaped support is equipped with universal wheels, which can move the shaped support to connect with the conduit, and can also be moved as a whole. Conduit, convenient construction, avoiding the laborious, time-consuming and unsafe use of manually moving the conduit; when the conduit is on the shaped support for water tightness test, the flatness can be adjusted through the shaped support to avoid the stress on the conduit caused by the uneven site Deformation; the position of the movable stopper can be adjusted through the movable hinge and the clamping rod, so as to adjust the height of the conduit placement and realize the flipping of the conduit, which is convenient and quick; setting water baffles on both sides of the shaped support can avoid spraying during the watertightness test. Water creates chaos on the construction site.

Description

technical field [0001] The invention belongs to the field of caisson construction, and in particular relates to a construction method of a pile foundation concrete pouring conduit control device. Background technique [0002] The conduits for pouring concrete in bored piles usually use steel conduits, and the use of conduits to pour concrete requires strengthening control of the strength of conduit joints, conduit leakage control, stability control during conduit pouring, verticality control, and the relationship between conduits and concrete liquid levels. Relatively high control, whether these control measures are appropriate or not has a huge impact on the quality of conduit construction. The steel conduit is heavy, the concrete pouring force is large, and the internal water pressure is large. Before the formal pouring, a tensile test and a hydraulic test are required. During the pouring process, the stability and verticality of the conduit must be controlled to prevent t...

AI Technical Summary

Problems solved by technology

The traditional technology is not systematic enough for the above control measures, and the control method is relatively rough, often using manual and empirical methods, and the control method is uncontrollable

The traditional technical problems are mainly as follows: the tensile test cannot be completed on site; the water tightness test is manually tested on the floor, the test conditions are simple, the labor requirements are high, and the components are greatly affected; the insertion depth of the conduit in the concrete is controlled by manual measurement. The measurement of the hammer is highly subjective; the stability control of the catheter is insufficient, and the height control of the catheter is not easy to adjust, etc.
