Problems solved by technology

However, since most of the dams are accumulated by natural soil, it is usually difficult to accurately determine the huge volume, loose soil, material composition and physical and mechanical properties.
When artificial dams are built, some commonly used reinforcement measures are difficult to apply directly, so an effective reinforcement structure for the dam body is needed

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the drawings.

[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 cement body 2 is constructed on the dam body 100.

[0027] The barrier body 100 is mainly caused by factors such as volcanic lava flow, moraines, geological disasters, or seismic activities that cause rocks on the mountain to collapse to block the valley, forming a water-retaining body similar to a dam in the valley. However, the dam body 100 is not fixed and permanent. The structural strength of the dam body 100 will also be reduced due to factors such as erosion, erosion, dissolution, and collapse. Once the dam body 100 is destroyed, the lake water Will overflow and cause floods. Therefore, in order to increase the structural strength of the dam body 100, it is necessary to strengthen the dam body 100 to ...

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] Barriers are caused by volcanic lava flows, moraines, geological disasters or seismic activities that cause rocks on the mountain to collapse, causing landslides, blocking valleys, and forming water-retaining bodies similar to dams in the valleys. However, dammed lakes have problems such as complex material components, serious lack of information, large subsidence, collapse, and long-term deformation that are difficult to predict, so that the dammed body is prone to erosion, erosion, dissolution, and collapse. For dangerous dammed lakes, manual excavation, blasting or interception must be used to divert the water in order to lower the water level in the dammed lake and avoid major floods. [0003] In recent years, in order to realize the disaster reduction and...
