Pressure double-control mold grouting all-in-one machine

Abstract

The invention relates to a pressure double-control arch top mold grouting all-in-one machine. The all-in-one machine is particularly suitable for use in tunnels, galleries, geotechnical engineering, foundation engineering, pile foundation engineering, water conservancy projects, chemical departments and metallurgical steel departments. The all-in-one machine comprises a traveling mechanism, a pulping mechanism, a grouting mechanism, a pumping mechanism and a PLC control mechanism. According to the all-in-one machine, double-layer design is achieved, upper-layer pulping, lower-layer mixing, front-end grouting, grouting pressure and flow automatic printing are adopted, so that one device can be automatically grouted, the equipment investment is reduced, the grouting efficiency is improved bymore than twice, the labor intensity of field operators is reduced, meanwhile, the quality of a tunnel lining is greatly improved, the grouting material adopts high-fluidity micro-expansion early-strength slow-setting filling mortar, and forms an organic whole with the two-lining concrete, so that the defect of two layers of the traditional slurry and the two-lining concrete is overcome.

Description

technical field [0001] The invention relates to an all-in-one machine for grouting with a mold for a pressure double-controlled vault, which is especially suitable for use in tunnels, tunnels, geotechnical engineering, foundation engineering, pile foundation engineering, water conservancy engineering, chemical industry departments, and metallurgical iron and steel departments. Background technique [0002] Since 2010, a number of railway tunnels have suffered problems such as arch cracking and falling off, repairing and falling off, knocking sound, leaking water gouging and repairing falling off, water gushing and other diseases, which seriously threaten the safety of traffic. During the static inspection and acceptance of some lines, the opening was seriously delayed due to tunnel quality problems. It has seriously affected operations and safety, and caused huge economic losses. In order to solve the hollowing of the tunnel lining vault, avoid the "double skin" phenomenon ...

AI Technical Summary

Problems solved by technology

[0002] Since 2010, a number of railway tunnels have had arch cracks and pieces, repairs falling off, knocking sound, water leakage, gouging repairs and falling off, water gushing and other diseases, seriously threatening traffic safety

[0003] The traditional process is to conduct radar scanning after the lining concrete is poured, and find holes to drill and grout. It is a post-injection method, that is, to find problems and solve them. Since the concrete has finally set, it is difficult to combine the newly injected slurry with the hardened concrete.

[0004] RPC pre-embedded grouting pipe technology is the requirement for grouting process equipment specified in the document [Interim Requirements for Tunnel Grouting with Formwork]. High flexural strength, low water-cement ratio, high viscosity, and high fluidity of grouting materials, it is difficult for conventional methods to meet the requirements while ensuring high efficiency

[0005] In order to strengthen tunnel quality supervision, the construction unit must monitor the grouting at any time, and then reverse the quality of the lining concrete. Therefore, higher requirements are placed on the amount of grouting and the time of grouting. The grouting volume, grouting time and grouting pressure cannot be controlled. In order to solve the above problems, our company has carried out related designs to meet the needs of the site.
