Construction method of drilling device for complex high and steep side slope

Abstract

The invention discloses a construction method of a drilling device for a complex high and steep side slope. The drilling device comprises a drilling machine support, a drilling machine base and a drilling machine; the drilling machine support comprises a sliding plate, a chassis is arranged on the sliding plate, the front end of the chassis is hinged to the front end of a platform, a supporting component is hinged to the platform and connected with a chassis fastener, and the width of the chassis and the width of the platform are adjustable; and the drilling machine comprises a power distribution system, an air compression system, a gear, a rock drilling component, a soil drilling component, a drill rod and a drill bit. The construction method comprises the following steps of 1, pulling the drilling machine support to a specified position; 2, unfolding and locking the support; 3, adjusting the angle between the chassis and the platform; 4, mounting the drilling machine; and 5, startingdrilling. The device solves the problem that it is difficult to drill in the complex high and steep side slope, can adapt to various rock-soil body stratums, can cope with complex slope surface conditions such as concavo-convex surfaces and flourishing forests, is flexible in action and safe and reliable in performance, and can fully cope with existing complex high and steep side slope reinforcement engineering.

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...

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
