Description
Technical Field
The utility model relates to a continuous steady voltage cementer of no pulsation. Is applicable to the technical field of grouting devices.
Background
In the grouting technical field, different name definitions are provided under different grouting pressure conditions, wherein grouting under the pressure lower than 3.0MPa is called conventional pressure grouting, and medium pressure grouting of 0.5-3.0 MPa and low pressure grouting of less than 0.5MPa are divided; the grouting at a pressure of 3.0Mpa or more is called high pressure grouting, and the grouting more than 20.0Mpa is also generally defined as ultra high pressure grouting. The most common grouting pressure is below 3.0Mpa, and the grouting method is generally used for crack grouting, foundation consolidation grouting, backfill grouting, contact grouting, curtain grouting and the like.
According to different properties of a grouted body, the requirements on grouting pressure and flow are different, so that the requirements on equipment are different greatly, common grouting equipment comprises a gear pump, a plunger pump, a diaphragm pump, an extrusion pipeline pump, a screw pump and the like, and the optional space is large, wherein the double-screw pump and the improved plunger pump can realize relatively stable pressure flow and are used for continuous grouting, and other pumps do work in a mechanical reciprocating manner or intermittently discharge a certain volume of slurry and have a pressure pulsation phenomenon.
Grouting is to make grout penetrate into weak zones such as cracks, cavities, holes and the like, and after the grout is solidified, the grouting has the effects of seepage prevention, leakage stoppage and reinforcement, some grouting requires that the original grouted body structure is not disturbed as much as possible, the splitting phenomenon (pressure instant extrusion channel) is generated as little as possible, and if the grouting is performed as the underground water line, the grouting can slowly permeate and stably permeate, the maximum construction safety of the grouted area can be achieved.
During medium-high pressure grouting, a small amount of pulsating pressure is even, the whole influence is not great, and as long as the power of the equipment is properly selected, the pressure change can be generally controlled within 20 percent and is within an acceptable range. And low pressure grout all has its particularity, and the pressure is steady all can be required in general design, prevents the phenomenon such as concrete lift, bulging that probably leads to. At present, a small-sized high-pressure chemical grouting machine is adopted to grout cracks of a wall body or a basement, and the phenomenon that concrete is cracked and secondarily deepened is serious due to overlarge pulse pressure change. The industry also carries on the research of many innovative improvement methods and apparatuses in the aspect of low-pressure flood irrigation technique, or because the apparatus is too complicated, or because of the poor commonality, there is not very common low-pressure flood irrigation apparatus so far, among them with the screw grouting pump type "a water conservancy concrete crack grouting apparatus CN 201620313052.9", output with its stable relative low pressure, and there are some applications, through the miniaturization of the apparatus, install the microcomputer control additional, can realize the continuous stable grouting of lower pressure, but because the apparatus screw contacts with slurry more, it is more troublesome to wash, need the electrical machinery to do work continuously at the same time to maintain the pressure; in addition, the equipment ZL201420140632.3 for long-time pressure-stabilizing chemical grouting can realize long-time low-pressure flood grouting and is more suitable for research under laboratory conditions, when the total grouting amount is large, pipelines need to be closed intermittently, grouting is carried out after normal-pressure grout supplement, and grout feeding amount measurement, data analysis and the like are also deficient; the other crack grouting method is also a common technology, namely a method of adopting a needle cylinder, adding a rubber band for storing force and slowly extruding into a crack is only suitable for treating the defects of thinner concrete and the like of a floor slab crack, a small amount of slurry in the needle cylinder penetrates into the crack for reinforcement, the pressure is gradually reduced along with the relaxation of rubber, and the method is difficult to be applied to the large-volume concrete crack grouting treatment.
Generally speaking, grouting is a technical activity, and is particularly a good activity, because many factors can be controlled and are difficult to control, because the weak change of pressure or slurry inlet rate is probably caused by slurry bleeding, slurry running, slurry stringing and the like, the grouting effect analysis is facilitated, the pulse condition of people is the same, and the existing technology is often not sensitive to the pressure and the slurry inlet rate enough, so that the grouting technology and the development are an important promotion direction.
