However, the dams and embankments of reservoirs or canals, as a line of defense to maintain the safety of water conservancy projects, have become the guarantee of people's life safety. However, dam bursts caused by piping or water seepage occur from time to time, and due to the uncertainty of their occurrence, they are more harmful In the prior art, as the document of CN102051896, the Chinese Patent No. provides a scheme for solving dam piping, which can be dealt with in time when a dangerous situation occurs, and prevents the piping from further causing the embankment to break. , failed to fundamentally prevent the occurrence of dangerous situations; the Chinese patent No. CN102051868 document uses the method of drilling and grouting in the dam body to fill the internal void and reinforce the dam body, thereby preventing water seepage of the dam body, but the outer part of the dam body is still Soaked in water, even if the concrete stone bank dam with high strength is eroded by water for a long time, cracks will appear on the outer dam body, which will cause the outer dam body to collapse, thus destroying the entire dam body structure

Embodiment 1

[0038] Such as figure 1 As shown, the dam body 1 in the present embodiment, the shroud 2, and the grouting pipe 3.

[0039] Such as image 3 and Figure 4 As shown, the enclosure 2 made according to the shape of the outer side of the dam body includes three panels, which are respectively inclined panels 5 and side panels 6 on the front and rear sides. When the inclined panels 5 are parallel to the outer side of the dam body, the side panels 6 Just perpendicular to the outer surface of the dam body, the edge of the side panel 6 suitable for fitting with the dam body is provided with a sealing strip 7, and the sealing strip 7 is suitable for sealing against the side surface of the dam body; A layer of plastic film is pasted on the inner surface, the material of the enclosure 2 can be plastic or metal, and the width of the side panel 6 (including the sealing strip) is 5-10 cm.

[0040] Such as figure 1 and figure 2 Shown, the dam reinforcement method of the present inventio...

Embodiment 2

[0050] The slurry described in the present invention adopts a two-component high-strength foaming resin, the model of which is SZ2. The two-component high-strength foaming resin includes two components: special resin and hardener. Put the two components into the above-mentioned grouting equipment at the same time. After the two components are mixed, a chemical reaction occurs, and the volume expands rapidly to form a foamy slurry. The exit viscosity of the slurry is 200±65mPa·s. The volume continuously expands in the flow, and the permeability is strong. It is suitable for quickly filling the space and expelling accumulated water under pressure. When the above slurry is injected for 10 minutes, it is completely solidified and reaches its final strength. Its compressive strength is ≥ 1.5MPa, and its Bending strength ≥ 1.3MPa, the slurry does not chemically react with water and is incompatible with water.

[0051] Compared with the existing underwater reinforcement slurry, the s...

Abstract

The invention relates to a dam reinforcement method and a reinforcing sizing agent. The dam reinforcement method comprises the following steps: selecting a section of dam needing to be reinforced, and manufacturing an enclosing cover adapting to a dam body according to the shape of the dam body; placing the enclosing cover on the outer side of the dam body, wherein the lower end of the enclosing cover is inserted in underwater silts and the upper end of the enclosing cover emerges from water, and side panels of the enclosing panel are arranged close to the outside surface of the dam body and cling to the outside surface of the dam body through sealing strips; placing a plurality of grouting lines in the enclosing cover in sequence, wherein the lower ends of the grouting lines extend into the bottom of the enclosing cover; grouting grouting holes and detecting the sizing agent filling condition immediately by an underwater camera, filling the inner space of the enclosing cover with the sizing agent from the bottom of the enclosing cover gradually, and draining water accumulated in the inner space from the top of the enclosing cover, and when the sizing agent overflows from the top of the enclosing cover, stopping grouting; after the sizing agent is fully solidified, taking down the enclosing cover and carrying out hole sealing on the grouting lines; forming a waterproof reinforcing structure layer on the outer side of the dam after the sizing agent is solidified to prevent water from seeping into the dam body or damaging the dam body due to erosion of water to the surface of the dam body.

Description

technical field [0001] The invention relates to a method for reinforcing a dam, which can reinforce the dam. Background technique [0002] In recent years, my country's water conservancy infrastructure has developed rapidly, including new large and small reservoirs, South-to-North Water Diversion Project, etc., which have provided guarantees for the development of the national economy. However, the dams and embankments of reservoirs or canals, as a line of defense to maintain the safety of water conservancy projects, have become the guarantee of people's life safety. However, dam bursts caused by piping or water seepage occur from time to time, and due to the uncertainty of their occurrence, they are more harmful In the prior art, as the document of CN102051896, the Chinese Patent No. provides a scheme for solving dam piping, which can be dealt with in time when a dangerous situation occurs, and prevents the piping from further causing the embankment to break. , failed to f...
