Background

The grouting pump is mainly suitable for the projects of grouting, water plugging, gap filling, broken rock stratum reinforcement and the like in construction sites such as mines, tunnels, water conservancy, subways, buildings, bridges and the like; the mining equipment is used for construction by matching with multi-component chemical series products such as Kanfu filling, Eucarnib rock stratum reinforcing agent, water plugging agent and the like. The grouting method is an effective technical means for preventing and treating water damage of underground engineering and reinforcing weak stratum, and is also a subject gradually summarized and developed in long-term practice. The grouting technology is very practical, the research on the grouting theory at home and abroad at present is greatly lagged behind the engineering practice, and the technical parameters are mostly combined by theoretical calculation and empirical statistics. In principle, the grouting technique usually uses a grouting pump as a power source, and injects prepared slurry with filling and cementing properties into a water-containing or weak unconsolidated rock (soil) layer through a slurry delivery pipeline and a grouting hole by using the pressure provided by the grouting pump, so that the slurry is diffused into cracks, pores or cavities of the stratum in the forms of filling or permeation, and the like, and after the slurry is condensed, the cracks, the water channels, the unconsolidated rock (soil) bodies and the cavities are sealed, thereby playing a role in water plugging or strengthening. The grouting method for sinking the well is to firstly use the grouting technology to plug the underground water-bearing layer to form a waterproof curtain and then carry out the shaft digging construction. The grouting process comprises the contents of selecting a grouting scheme, determining a grouting mode, determining a grouting depth, arranging drill holes, drilling a method, selecting equipment types, arranging a grouting system, designing grouting parameters, controlling grouting construction quality, checking effects and the like. The grouting material is a slurry or a raw material for preparing the slurry which is injected into the stratum and can play a role in water plugging and strengthening in fractures or pores, and is the key of water plugging and strengthening. If the grouting technology can meet the quality requirement, firstly, a grouting material suitable for the injected stratum needs to be selected. The research and development of novel grouting materials are important ways for expanding the application range of grouting technology. The grouting equipment comprises a grouting pump, slurry stirring and mixing equipment, a slurry stopping device, a pipeline, a metering and monitoring instrument and the like, which jointly form a system for preparing and conveying slurry and provide a power source and a channel for the slurry to enter a stratum to be grouted. The mechanical, automatic and informatization is one direction of the development of grouting equipment while the applicability of the grouting equipment to processes and materials is improved

The reversing mechanism of the existing grouting pump has the defects that the reversing mechanism is easy to wear after being used for a long time, internal parts are easy to damage due to large impact load borne by the reversing mechanism, and an oil tank leaks oil due to long-time friction of a piston rod in an oil cylinder.
