Problems solved by technology

[0002] After the cast-in-situ pile is drilled with a drilling rig, especially when the mud wall is used, there will be a certain thickness of sediment at the bottom of the hole. If the thickness of the sediment is not found out and treated in time, it will be the vertical compression resistance of the cast-in-place pile. Bearing capacity and settlement have serious adverse effects

Abstract

The invention relates to a cast-in-place pile hole bottom sediment thickness detecting and reinforcing device and a construction method thereof.The device comprises a base, a lifting platform, a rotating power device, a pushing rod, a grouting pump and a probe tube, the lifting platform and the rotating power device are installed on the base, the lifting platform drives the pushing rod to ascend and descend, and the rotating power device drives the pushing rod to ascend and descend; the rotating power device drives the pushing rod to rotate, the exploring tube is fixed below the pushing rod, a torsion detector is arranged on the lower portion of the exploring tube, a resistance plate is arranged on the lower portion of the torsion detector, the resistance plate is fixed on the exploring tube, and a grout outlet hole is formed in the lower portion of the exploring tube. The thickness of sediment at the bottom of the hole can be quantitatively detected, and meanwhile, the sediment is reinforced by utilizing a built-in grouting system of the device. Compared with a traditional process, the method has the advantages of quantification, simple process, thorough sediment treatment and the like.

Description

Technical field [0001] The present invention relates to the field of drilling and infusion pile construction. Background technique [0002] After the pile is used to use the drilling machine, in particular, the pile will hold a thickness of the sediment that the hole will have a thickness of a thickness, and if the thickness of the sediment is not proven, it will be the vertical pressure of the infusion pile. Bearing capacity and sedimentation have serious adverse effects. [0003] At present, after the pile is in the mechanical depum, the construction personnel perform a slag thickness detection, and if the slag thickness is greater than the specification, the "anti-cycle" mode is performed. The thickness of the sediment is mainly to use a sling of the construction personnel to use a sling to determine the thickness of the residue to determine the resistance of the heavy weight, which is very subjective and non-quantitative. If the weight and shape of the weight and the shape of...
