A Composite Material with Reinforcement and Drainage

Abstract

The invention discloses composite materials both provided with the functions of rib adding and water discharge. The composite materials both provided with the functions of the rib adding and the water discharge comprise an outer layer geotextile (1), an inner layer core plate (2) and rib adding materials (3). Ribs are respectively or simultaneously added to the inner layer or the outer layer of water discharge geotextile materials in an appropriate mode, or the inner layer and the outer layer of the water discharge geotextile materials are reliably connected at intervals by other various ordinary reinforced geotextile materials and geotextile water discharge materials according to certain rules. The composite materials both provided with the functions of the rib adding and the water discharge have the advantages of being various in combination form, simple in machining and manufacture, wide in application range, capable of being used for piling and building dams, managing weak, dangerous and risky tailing impoundment dams, filling new-filled side slopes and new-built road embankments and the like, also capable of being widely used in the field of geotechnical engineering for strengthening the side slopes, managing landslides and the like, wide in market application prospect, also capable of completing the dual functions of the rib adding and the water discharge for once construction, capable of more facilitating speeding up consolidation of soil bodies than ordinary materials, particularly applicable to reinforcement and improvement of filling the side slopes with fine grain disperse bodies, friendly in environment during a construction process, free of environmental pollution in construction through either a pre-buried method or a postposition method, simple in procedure and process during the construction, low in construction cost compared with a regular method, and particularly more reliable in quality.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and specifically relates to a treatment, tailings dam dam construction and treatment of diseased, dangerous and dangerous tailings dams, fill slope filling and reinforcement treatment, and has the function of reinforcement Composite materials with drainage function. Background technique [0002] Most of the existing tailings accumulation dams use reinforcement methods to solve the stability problem of the reservoir dam. Many geotechnical engineering fill slopes also use layered reinforcement technology for slope treatment. The traditional methods all or only use geogrid, geotechnical Reinforce the filler with tape and geotextile to improve its physical and mechanical properties and increase the overall stability of the fill slope; or simply set drainage (seepage) channels in the filler to improve its shear strength parameters by draining the water in the filler. The purpose of s...

AI Technical Summary

Problems solved by technology

However, in the construction process, filler reinforcement and drainage (seepage) channels need to be constructed separately, and different materials are used, the process is complicated, the process is complicated, the material consumption is large, the cost is high, and the quality reliability is poor; especially the use of fine-grained soil for filling When it is impossible to set too many drainage (seepage) channels, it takes a long time for the fill slope or dam body to stabilize, and the stability safety factor is low.
