Embodiment 1

[0015] The present invention is a retractable engineering pile into rock controller, which is characterized in that it comprises a steel plate top support 1, an expansion joint 2 and a steel plate bottom support 4; the expansion joints 2 are several, and are connected end to end to form a telescopic whole, It is arranged between the steel plate top bracket 1 and the steel plate bottom bracket 4 .

[0016] In this embodiment, the adjacent expansion joints 2 are connected by expansion joint buckles 3 .

Embodiment 2

[0018] A shrinkable engineering pile entry control method of the present invention adopts the shrinkable engineering pile entry controller described in Embodiment 1. During engineering pile construction, when the drill bit 6 of the drilling rig is about to enter the rock layer 7, the drilling rig Set the steel plate top support 1 and the steel plate bottom support 4 on the 5 sides of the drill pipe, and set the number of expansion joints 2 according to the depth of rock penetration, and then carry out piling. At this time, the length of expansion joints 2 extracted during piling construction is the actual rock penetration depth. .

[0019] The application of the invention can effectively control the depth of the engineering piles in strict accordance with the design requirements during the construction of the engineering piles, effectively ensure the construction quality of the pile foundation, reduce labor and other comprehensive costs, reduce the labor intensity of constructi...

Abstract

The invention discloses a retractable engineering pile embedment-in-rock controller, which comprises a steel plate top support, telescopic joints and a steel plate bottom support. The plurality of telescopic joints are sequentially connected end-to-end by telescopic joint buckles to form a telescopic whole body, which is disposed between the steel plate top support and the steel plate bottom support. The invention also discloses a retractable engineering pile embedment-in-rock control method. The controller and the control method in the invention can be applied to effectively control the embedment depth in rock of an engineering pile strictly in accordance with the design requirements in the construction process of the engineering pile, thereby effectively ensuring the quality of the pilefoundation construction, meanwhile reducing the comprehensive cost such as labor cost, reducing the labor intensity of construction personnel, and improving the labor production efficiency of pile foundation construction.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a retractable engineering pile entering rock controller and a control method. Background technique [0002] Pile foundation construction has high requirements on the quality of the piles, especially the quality control of the rock-inserted part, which is a key factor in the pile foundation construction. No related similar information was retrieved. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the above-mentioned background technology, the purpose of the present invention is to propose a retractable engineering pile entry controller and control method, and the application of the present invention can effectively control the depth of the drill bit into the rock during piling construction to meet construction requirements. [0004] The technical scheme that the present invention solves the technical problem is as follows: [000...
