Novel agitation vat and construction method applied to fracture grouting of civil engineering

Abstract

The invention discloses a novel agitation vat and a construction method applied to fracture grouting of civil engineering, relates to the technical field of the civil engineering, and particularly relates to a novel agitation vat and a construction method applied to fracture grouting of the civil engineering. The novel agitation vat comprises an agitation container and a power device; the power device is arranged inside the agitation container; an additive container device is installed at the upper portion of a steel bracket; and the power device comprises a motor, a belt, a rotating wheel, astirring rod fixing device, a stirring rod and an impeller. The novel agitation vat and the construction method applied to fracture grouting of the civil engineering can control the proportion of an additive in a fracture grouting process, can also stop or use mixed grout immediately in order to seal wide and large cracks so that more thin and weak surfaces are fractured to form grout veins, thusthe aim of reinforcing the foundation is realized; time is saved; labor and materials are saved; the construction conditions are improved; and formation of a novel working method can be promoted, so the construction technique for fracture grouting is more advanced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a novel mixing tank and construction method for splitting grouting in civil engineering. Background technique [0002] During the splitting grouting process, under high pressure, the weak surface of the rock mass or loess layer is easily split to form branches, which then play a role in reinforcement. However, when the weak crack is too large, a large amount of grout will flow through the crack. The outflow also makes the pressure in the hole dissipate, making it impossible to split other weak surfaces, which can not achieve the purpose of foundation reinforcement, but also causes a serious waste of grout. [0003] In the currently used split grouting construction technology, when the grout leak is visible or obvious, water glass is added to seal it, but it cannot meet the immediate stop and use of the mixed grout of cement slurry and water glass, timely plugging and re...

[0002] During the splitting grouting process, under high pressure, the weak surface of the rock mass or loess layer is easily split to form branches, which then play a role in reinforcement. However, when the weak crack is too large, a large amount of grout will flow through the crack. The outflow also makes the pressure in the hole dissipate, making it impossible to split other weak surfaces, which can not achieve the purpose of foundation reinforcement, but also causes a serious waste of grout

[0003] In the currently used split grouting construction technology, when the grout leak is visible or obvious, water glass is added to seal it, but it cannot meet the immediate stop and use of the mixed grout of cement slurry and water glass, timely plugging and re-use. Can form new branches, resulting in a waste of time, manpower, and material resources
