Description

Double-liquid same-frequency difference grouting pump

Technical Field

The utility model belongs to the technical field of grouting pumps, and particularly relates to a dual-liquid co-frequency difference grouting pump.

Background

Currently, there are many grouting works involved in modern engineering construction, in which a two-fluid grouting process is often used. The double-liquid grouting is a process for injecting two building materials with different properties or additives into rock mass or structure according to a certain proportion by a double-liquid grouting machine, so that the two liquid materials generate chemical reaction in rock stratum, and the following reactions can be generated according to the different additives: rapid setting, retarding, flocculating, expanding, etc.

The geological conditions of each construction surface are different, the types of the used additives are also different, and each construction purpose is also different, so the mixing proportion of the additives and the main materials is also different. In high-pressure pouring, in order to meet the quality after construction, the following conditions are required to be provided during pouring, and two slurries should be kept in a grouting pipe: the pressure is the same, the flow rate is the same, and the time to enter the mixing section is the same.

When the mixing ratio of the two slurries is 1:1, the existing equipment is easier to control, but when the mixing ratio of the two slurries is different, the accuracy of the mixing ratio is difficult to control, such as 0.9:1.

The existing grouting machine has the defects that: the two slurries enter the mixing section to be asynchronous, which means that the mixing ratio is easy to deviate, and the mixing effect is affected.

When the unequal amount is poured, some grouting machines adopt single-cylinder speed regulation, the reciprocating frequency of a piston is reduced to reduce the suction pressure quantity, but the mixing ratio is not accurate enough, and the pressure and the mixing steps are inconsistent.

There are also methods of branching the branch pipe at the single cylinder outlet of a dual cylinder grouting machine, but this also causes pressure loss, and even under pressure differences, the high pressure cylinder may flow backward into the low pressure cylinder.

Two single-cylinder grouting machines are adopted to be used in parallel, and the injection quantity is changed by adjusting the speed of one single-cylinder grouting machine, but the mixing ratio is inaccurate and is not easy to operate.

Through the above analysis, the problems and defects existing in the prior art are as follows: when the mixing ratio of two slurries is different, the existing grouting machine is difficult to control the mixing ratio accuracy, and deviation is easy to generate, so that the slurry mixing effect is affected.
