Abstract

The invention discloses a reinforcement construction method and particularly relates to a construction method for reinforcing a large rock slope deep weak structural plane. The construction method comprises the following steps: A, excavating a main tunnel along the direction of the deep weak structural plane of a rock slope, performing temporary support, and then drilling drainage holes on a tunnel soffit; B, excavating branch tunnels from two side walls of the main tunnel to the top wall and bottom wall directions of the deep weak structural plane, performing temporary support and then drilling drainage holes on tunnel soffits; and C, backfilling concretes into the main tunnel and the branch tunnels, and arranging steel bars to reinforce the backfilled concrete, wherein concrete backfilling is at least divided into two following construction period: in the first construction period, the backfilled concretes are backfilled along the peripheral inner walls of the main tunnel and the branch tunnels in a covering way, backfilling layers of the first construction period are formed on the walls of the main tunnel and the branch tunnels after the first construction period of concrete backfilling is finished, and the residual spaces of the main tunnel and the branch tunnels are utilized as grouting galleries; and after the backfilled concretes of the first construction period are solidified, the backfilled concretes of the residual construction period are utilized to fill the whole grouting galleries.

Description

technical field

[0001] The invention relates to a reinforcement construction method, in particular to a construction method for reinforcement of a deep weak structural surface of a large rock slope. In addition, the invention also relates to a reinforcement construction structure, especially a construction structure for reinforcement of a deep weak structural surface of a large rock slope. Background technique

[0002] Many infrastructure projects such as water conservancy and hydropower, railways, highways, and mines in my country are located in alpine and canyon areas, and the construction of these projects often involves large-scale rock slope engineering. Under the action of geological structure, the rock mass inside the slope often develops weak structural surfaces such as faults, dikes, and joint fissures, which constitute the potential sliding failure surface of the slope. The further effects of natural forces and human activities may cause further deformation, loose...
