Problems solved by technology

[0005] The purpose of the present invention is to provide a rotary drilling bucket jacking type slag discharge noise reduction construction method, which solves the problem that when the rotary drilling rig uses the rotary drilling bucket to drill in the background technology, the drilling slag often occurs in the drilling bucket. The inner wall is difficult to discharge smoothly. When the rotary drilling drill encounters the difficulty of slag discharge, the rotary drilling machine operator usually operates the drill bucket forward and reverse alternately to impact and throw the soil, or through the emergency braking during the rotation process, the drill Drilling slag was shaken out in the bucket, and the whole process of slag removal produced a lot of noise, which caused the surrounding environment noise to exceed the standard, which brought great troubles to the normal life of residents. In serious cases, they were even ordered to stop work for rectification, which greatly affected the construction of foundation projects. progress problem

Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] In order to solve the technical problems that the whole process of slag discharge produces a lot of noise, which causes the surrounding environment noise to exceed the standard and brings great troubles to the normal life of residents, such as Figure 1-3 and Figure 12 As shown, the following preferred technical solutions are provided:

[0042] The construction method for noise reduction of slag discharge by rotary drilling bucket, including the follo...

Abstract

The invention discloses a rotary excavating drilling bucket pushing type deslagging noise reduction construction method, belongs to the technical field of rotary excavating drilling buckets, and aims to solve the problems that when a rotary excavating drill encounters the condition that deslagging is difficult, a rotary excavating machinist usually operates a drilling bucket to rotate forwards and backwards alternately to impact and throw soil, or drilling slag in the drilling bucket is shaken out through an emergency brake measure in the rotating process, the whole deslagging process generates large noise, and the deslagging effect is poor. The noise of the surrounding environment severely exceeds the standard. The pressure-bearing disc on the upper portion of the drilling bucket is pushed downwards through the drilling machine power head, the pressure-bearing disc pushes the slag discharging plate arranged in the drilling bucket to move downwards through the dowel bar, and therefore slag adhering to the inner wall of the drilling bucket is completely pushed out; the pushing type drilling bucket is adopted for deslagging, deslagging can be completed only by lifting the drilling bucket to make contact with a power pressure plate of the rotary drilling machine to generate continuous pushing force, noise pollution in the deslagging process is greatly reduced, and the noise pollution is greatly reduced especially in a site with strict noise control. And the construction period delay loss caused by shutdown due to complaint caused by overlarge noise is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of rotary drilling buckets, in particular to a construction method for pushing slag and noise reduction of rotary drilling buckets. Background technique [0002] Compared with other traditional pile driving equipment, rotary drilling rig has the advantages of high degree of automation, low labor intensity and high construction efficiency, and has been widely used in pile foundation engineering. The construction technology of the operation is widely used in foundation construction projects such as municipal construction, highway bridges, high-rise buildings, etc., and is suitable for dry or wet hole-forming operations in rock formations with different drilling tools. [0003] When the rotary drilling rig uses the rotary drilling bucket to drill, there are often problems that the drilling slag is blocked in the drilling bucket and adheres to the inner wall, making it difficult to discharge smoothly. Usually, ...
