Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The technical solution of the present invention is: find a suitable location on the site to set up a temporary preparation point, store well-assembled gravel or crushed stone, Portland cement, and various admixtures in time, use a sewage suction pump to suck the mud from the mud pit and remove it in time Replenish the water, and the extracted mud is made of mud solidified by using the mud generated by the drag pipe, well-prepared sand and gravel or gravel, and Portland cement according to a certain ratio. pump the mud into the storage tank, add lime to stir, adjust the pH, and then add a certain amount of p...

Abstract

The invention discloses a dragging pipe slurry condensate as well as a preparation method and an application method thereof. The condensate comprises dragging pipe slurry, an adsorption and water absorption material, a cementing and curing material and an additive, wherein the adsorption and water absorption material is one or two of sand gravel or gravel, the cementing and curing material is Portland cement, and the additive at least comprises one or two of an anti-freezing agent or an exciting agent. According to the method, the slurry generated by the trenchless dragging pipe can be reasonably consumed and utilized in the roadbed material, the risk of environmental pollution caused by the slurry is solved, and the problems of high slurry treatment cost, few technical choices and the like in the prior art are solved; the method has the advantages of simplicity in operation, high feasibility, low cost and suitability for large-scale popularization in preparation and application of the sandbar roadbed material.

Description

technical field [0001] The invention belongs to the technical field of application of drag pipe mud in sandbar subgrades, and in particular relates to a cured drag pipe mud and its preparation method and application method. Background technique [0002] In the trenchless pipe pulling construction, the mud generated by the pulling pipe often needs to find a designated mud disposal site. The treatment method is difficult, and it needs to be dried for a long time. There is no secondary use value, and it often forms alkaline hardening after long-term storage. The soil cannot grow green plants, and the treatment and application of mud has always troubled engineering construction. The current treatment method for mud is to degrade and separate in the sun. However, the degradation and separation of mud in the sun often takes a long time and consumes a lot of cost. Contents of the invention [0003] The object of the present invention is to provide a drag pipe mud solidification a...
