Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] Such as figure 1 as shown, figure 1 It is schematically shown that the reinforcement structure 200 includes a first cement body 2 and a first reinforcement body 3 . The first cemented body 2 is constructed on the damming body 100 .

[0027] The damming body 100 is mainly caused by factors such as volcanic lava flow, moraine, geological disasters or seismic activities causing the rocks on the mountain to collapse to block the valley, forming a water retaining body similar to a dam in the valley. However, the damming body 100 is not fixed and permanent, and the structural strength of the damming body 100 will also be reduced due to factors such as erosion, erosion, dissolution and collapse. Once the damming body 100 is destroyed, the lake water will It will overflow and form a flood. Therefore, in order to enhance the structural strength of the damming body 100 , i...

Abstract

The invention relates to a reinforcement structure for a barrier dam and a construction method of the reinforcement structure. The reinforcement structure comprises a plurality of layers of first cement bodies which are sequentially arranged on the surface of a first to-be-reinforced area of the barrier dam from top to bottom, wherein every two adjacent layers of cement bodies are in contact with each other to form a first reinforcement body of the barrier dam; and first grouting holes which are respectively communicated with the first cement bodies are formed in the first reinforcement bodies. The reinforcement structure has the advantages of being high in structural strength, good in soil mass stability, high in compactness and good in scouring resistance and permeation resistance.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a reinforcement structure for a dam body and a construction method thereof. Background technique [0002] The barrier body is caused by volcanic lava flow, moraine, geological disasters or seismic activities, which cause rocks on the mountain to collapse, thereby causing landslides, blocking valleys, and forming a water retaining body similar to a dam in the valley. However, due to the complex composition of the barrier lake, the serious lack of information, the large amount of subsidence and collapsibility, and the unpredictability of long-term deformation, the barrier body is prone to erosion, erosion, dissolution and collapse. For highly dangerous barrier lakes, manual excavation, blasting or interception are required to divert the water in order to reduce the water level in the barrier lake and avoid causing major floods. [0003] In recent years, in or...
