Gangue filling and road construction combined construction technology

Abstract

The invention discloses a construction technology combining gangue filling and road construction, and belongs to the technical field of gangue filling construction. The construction process comprises the following steps: preparing construction operation, cleaning the surface of a waste rock discharging field, shaping, building an initial waste rock blocking dam to a specified elevation, connecting an end point of an external approach road to the top part of the initial waste rock blocking dam, and piling waste rocks on the inner side of the initial waste rock blocking dam to an elevation below the top of the dam; road positioning, wherein on-site paying-off is conducted according to the plane design position and the design elevation of a road; gangue filling and road construction are conducted at the same time, and the elevation of the road construction end point is higher than the highest point of the gangue filling plane; road auxiliary engineering is constructed, a protective barrier and a drainage ditch are arranged on the road, and a gangue-carrying slope is subjected to greening protection. Gangue filling and road construction are carried out at the same time, the construction difficulty is lowered, the engineering amount is reduced, the construction progress is accelerated, then the initial engineering investment is reduced, and meanwhile the road can also be used for later reclamation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of gangue landfill construction, and in particular relates to a construction technology combining gangue landfill with road construction. Background technique [0002] In waste rock filling construction, the construction sequence is as follows: initial dam construction - approach road construction - waste rock filling - sub-dam construction - temporary access road construction - waste rock filling - reclamation and greening. [0003] In order to meet the requirements of construction technology and slope stability, it is generally necessary to carry out graded landfill and set up corresponding platforms. And set steps on all levels of platforms to meet the needs of later maintenance. [0004] Temporary roads are a common project in the waste rock filling process. In order to meet the needs of waste rock landfill, a temporary road is generally required for each level of waste rock platform to facilitate waste...
