Problems solved by technology

[0002] At present, the traditional engineering treatment of tailings dam accumulation dam is single seepage reinforcement (through seepage drainage to reduce the infiltration line) or single reinforcement reinforcement (by improving the physical and mechanical properties of the tailings dam), which need to be constructed separately during the construction process. , the construction process is complicated, the quality is difficult to guarantee, the material consumption is large, the drainage and reinforcement effect is poor, and the stability and safety factor of the dam body is low

Embodiment 1

[0022] according to figure 1 , shown in Fig. 2a, b, c, d, a kind of post-drainage reinforcement belt controls the new construction method of tailings accumulation dam, the first kind of implementation mode steps are as follows:

[0023] (1) According to the particle composition of the tailings, determine the vertical and horizontal spacing of the construction of the seepage reinforcement belt 1; generally 1.0 to 5.0m, take a small value when the particles are fine, and take a large value when the particles are thick; the construction example of the drainage reinforcement belt 1 is detailed See attached drawing 2, in the figure 7—the outer layer of permeable geotextile with drainage reinforcement, 8—the inner water collection core board with drainage reinforcement, 9—the drainage reinforcement with linear or grid-shaped reinforcement body;

[0024] (2) Use the horizontal inserting machine 2 to insert at an elevation angle of 3°-10° on the side of the dam body 3, which not only...

Embodiment 2

[0031] according to figure 1 , shown in Fig. 2a, b, c, d, the second embodiment steps are as follows:

[0032] (8) Complete the setting of the horizontal drainage reinforcement body 6 according to steps (1) to (7);

[0033] (9) Insert the seepage body vertically on the top of the tailings dam by using the inserting machine, the vertical and horizontal distances are 1.0-3.0m, and the insertion depth is overlapped with the horizontal seepage reinforcement body according to the design requirements;

[0034] (10) Form the combined effect of the horizontal seepage drainage reinforcement body and the vertical seepage drainage body to form a three-dimensional drainage and reinforcement system for tailings dam reinforcement.

Abstract

Provided is a new construction method of postposition drainage reinforced belts for governing a tailing fill dam. The new construction method of the postposition drainage reinforced belts for governing the tailing fill dam comprises the following steps: step(1), vertical and horizontal intervals of the drainage reinforced belt construction is confirmed; step (2), a horizontal plate-inserting machine is utilized to insert at an elevation on a side face of a dam body; step (3), according to a predetermined interval, the horizontal plate-inserting machine (2) is in position on a riding track of the tailing fill dam, then the drainage reinforced belts are implanted one by one, and a first horizontal drainage reinforced body row (6) is completed; step (4), a construction platform (4) of a second horizontal drainage reinforced belt row (1) is set up; step (5), the horizontal plate-inserting machine (2) is in position on the construction platform (4), then each drainage reinforced belt (1) on the second horizontal drainage reinforced belt row is inserted one by one, and a second horizontal drainage reinforced body row (6) is completed; step (6), the steps from step (2) to step (5) are repeated, and the construction of multi-row horizontal drainage reinforced bodies (6) is completed. The new construction method of the postposition drainage reinforced belts for governing the tailing fill dam has the advantages that by using the drainage reinforced belts, the drainage function is achieved, and the tailing is reinforced at the same time. Not only is a seepage line reduced through drainage, but also the anti-skidding ability of the tailing body is improved through the reinforcement, and compared with a regular method, existing ill, dangerous and risky tailing fill dams are enabled to be stabilized quickly.
