Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to an automatic pulping, grouting and sewage treatment system. Background technique [0002] In water conservancy and hydropower projects, in order to make the foundation meet the requirements in terms of water permeability, seepage stability, strength, bearing capacity, and compression deformation capacity, the foundation is often treated with grouting reinforcement; the main working links in the grouting work include: grouting, grouting, sewage treatment. [0003] Pulping is when workers add a certain weight of water into the mixing tank, then break the bagged cement ash out of the bag and weigh it, add it according to the required density ratio, and then turn on the stirring motor to start pulping.

Problems solved by technology

[0003] Pulping is when workers add a certain weight of water into the mixing tank, then break the bagged cement ash out of the bag and weigh it, add it according to the required density ratio, and then turn on the stirring motor to start pulping. During the pulping process, workers need to observe the slurry stirring After uniformity, turn off the stirring motor and check whether the density of the slurry is qualified. After the slurry is tested and passed, the worker will use a human trolley to send it to the station that needs to be grouted. During this process, a pulping team needs at least 3-4 people to participate in the pulping process. ;The quality of this pulping method has unfavorable factors such as difficult control, high labor input, manual limitation of pulping output, and easy occurrence of safety accidents in the process of pulping and pulping.

Grouting is to pump the cement slurry with the density required by the design into each grouting hole through the grouting pump according to the grouting requirements such as the design pressure; during this process, the workers need to prepare the previously prepared raw slurry into various required densities according to the requirements of the grouting technicians at any time. At the same time, workers need to operate the pressure regulating valve to adjust the grouting pressure in real time; manual preparation of grout density and pressure adjustment is not easy to control, and the manual investment is high. Due to the certain pressure of the grouting pipeline, there are certain safety risks during the grouting process

[0004] In the patent CN202011355463.1, an intelligent grouting and grouting system is disclosed, which automatically collects grouting data and makes real-time adjustments to adapt to grouting under various geological conditions. The sewage mainly comes from the large amount of sewage generated during the drilling and grouting process; during the drilling process, a large amount of water is required to cool the drill bit, flush the hole, and flush out the small particle stones at the bottom of the hole, etc.; After each batch of pulping is completed, it is necessary to clean the pulping equipment and tools in time for use (if the cement slurry is not cleaned in time, it will solidify on the contact surface between the equipment and the tools, which will easily make the equipment and tools unusable) and redundant The grout can only be discarded; at the beginning of grouting, water needs to be injected into the hole to clean the grouting hole. After each grouting, the grouting equipment and tools need to be cleaned in time for later use (if not cleaned in time, the grout will solidify on the equipment and tools. The contact surface can easily make the equipment and tools unusable) and the excess slurry can only be discarded, resulting in a large amount of sewage; in similar projects, the sewage treatment adopts the ordinary sedimentation method, which is to build one or more large sedimentation tanks, The sewage is uniformly introduced into the sedimentation tank and then discharged after being treated up to the standard; this sewage treatment method has disadvantages such as large area occupation, high engineering cost, non-reuse of engineering relocation, troublesome sludge cleaning, and long water diversion channels
