Embodiment Construction

[0019] The present invention is described in further detail below by embodiment, and embodiment is only used for illustrating the present invention, does not limit the scope of the present invention.

[0020] The present invention is implemented in the slope excavation process of Huangzangsi water control project in Heihe River, and the specific implementation process is as follows:

[0021] see figure 1 A kind of soil interbedded stone slope support construction method shown, comprises the following steps:

[0022] (1) Anchor pipe processing:

[0023] The soil anchor pipe is made of steel pipe, which is welded or cut according to the length required by the construction; the diameter of the steel pipe is 48mm, and the wall thickness of the steel pipe is 3mm;

[0024] (2) Measurement and positioning of anchor pipe hole 2:

[0025] Use the survey control network provided by the EPC department to set up the survey control network at the construction site, and use the total sta...

Abstract

The invention belongs to the field of construction of water-power engineering technologies, and particularly relates to a supporting construction method for a soil-rock slope. The supporting construction method comprises the steps of anchor pipe processing, anchor pipe hole measurement positioning, drilling, anchor pipe mounting, grouting and the like. The construction method of soil anchor pipe supporting is adopted, anchor pipe construction has incomparable advantages over other supporting modes for special geologies, especially the geologies with incomplete rock or poorly-developed rock, the hole forming efficiency of anchor holes can be ensured, the construction time is shortened to a certain extent, and the construction efficiency is improved.

Description

technical field [0001] The patent of the invention belongs to the construction field of hydropower engineering technology, and in particular relates to a construction method for earth-interbedded stone slope support. Background technique [0002] Under normal circumstances, water conservancy and hydropower projects are generally located in deep mountains and canyons, the geographical environment is quite harsh, the terrain is generally steep, and the geological conditions are generally poor. There are many deposits and collapsing deposits in the project construction area. These have brought great difficulties to the slope excavation construction. In the slope support construction, the main support methods include bolt support, plain shotcrete, sprayed concrete with reinforced mesh, and anchor cables. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a construction method for soil-rock slope support, which is...
