Construction method of a drilling device for complex high and steep slopes

Abstract

The invention discloses a construction method of a drilling device for complex high and steep slopes. The drilling device comprises a drilling machine support, a drilling machine base and a drilling machine. The drilling machine bracket includes a slide plate, on which there is a chassis, the front end of the chassis is hingedly connected with the front end of the platform, the supporting member is hingedly connected with the platform, and connected with the chassis fastener, and the width of the chassis and the platform can be adjusted; the drilling machine includes a power distribution system , air pressure system, gears, rock drilling components, soil drilling components, drill pipes and drill bits; construction methods include: 1) Pull the drilling machine bracket to the designated position; 2) Expand the bracket and lock it; 3) Adjust the chassis and platform Angle; 4) Install the drilling machine; 5) Start drilling. The invention solves the problem of difficult drilling of complex high and steep slopes, can be adapted to various rock and soil strata, and can deal with complex slope conditions such as unevenness and lush forests. It is flexible in action, safe and reliable in performance, and can fully cope with existing Reinforcement works for complex high and steep slopes.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a construction method of a drilling device for complex high and steep slopes. Background technique [0002] In the natural environment, there are a large number of dangerous slopes, which are always facing the possibility of instability and landslides. In order to ensure the safety of people's lives and properties, such dangerous slopes need to be artificially reinforced. However, the nature of the slope is more complicated (1) The stratum is complex, part of the surface layer of the slope is soil, and after a certain depth, it is rock mass. (2) The slope is complex. The vegetation on the slope is dense, the slope is uneven, and the soil is soft. Therefore, the traditional drilling technology has the following problems: (1) due to changes in the soil layer, frequent replacement of drilling equipment is required. (2) The soil is soft and the vegeta...

AI Technical Summary

Problems solved by technology

However, the nature of the slope is more complicated (1) The stratum is complex, part of the surface of the slope is soil, and after a certain depth, it is rock mass

(2) Complex slope

Therefore, the traditional drilling technology has the following problems: (1) due to changes in the soil layer, it is necessary to frequently replace the drilling equipment

(2) The soil is soft and the vegetation is dense, so scaffolding construction is not possible

(3) The existing movable drilling platform is too large to travel through the jungle

(4) The existing movable drilling platform is four-wheel type, it is difficult to travel on uneven roads, and the stability is poor when drilling

However, this type of solution has the following problems: (1) It takes a lot of time to replace, transport, assemble and check equipment, especially in the case of high slope support operations, it is very difficult to replace equipment, which increases the construction period

(2) Replacing or leasing different drilling equipment according to different formation conditions, which virtually increases the project cost

(3) Replacement and shifting of tools may easily cause hole position deviation, resulting in frequent drill pipe breakage accidents
