Description

Technical Field

[0002] In recent years, the domestic emerging shaping mud technology uses a mixture of clay mud and a curing agent to form a viscous mud with good fluidity and a certain strength after pouring and solidification. This new concrete-like material filling process technology is mostly used for fertilizer trough backfilling and is widely used in Xiongan New Area, Guangdong, Sichuan and other places. At present, the preparation and pouring process of shaping mud mostly adopts a similar concrete preparation and pouring process - that is, the prefabricated slurry is mixed in the factory and then transported to the site for intermittent pouring. Using this factory-mixed prefabricated slurry method, the transportation cost of qualified soil and slurry preparation is high, and it is difficult to form continuous pouring, and the pouring and backfilling efficiency is relatively low.

[0020] like Figures 1-2As shown, the shaping mud preparation and pouring system of this embodiment includes a primary mud pool 100, a mud regulating pool 200, and a shaping mud mixing pool 300, which are sequentially connected by pipeline transportation; a first stirring device 210 is provided in the mud regulating pool 200, and a second stirring device 330 is provided in the shaping mud mixing pool 300; there are two shaping mud mixing pools 300 in parallel, and the pipelines connecting the inlet and outlet ends of each shaping mud mixing pool 300 are respectively provided with a first valve 310 and a second valve 320. The primary mud pool 100, the mud regulating pool 200, and the shaping mud mixing pool 300 are connected in an orderly manner through valves, pipes, pumps, etc. to form a system, which can realize the continuous pouring of solidified soil slurry on-site preparation with less equipment investment and in a certain operating mode, thereby improving the pouring efficiency.

[0021] Among them, the primary mud pool 100 is prepared on-site for pouring, and the mud regulating pool 200 and the shaping mud mixing pool 300 are both movable equipment; in this way, it can ensure on-site preparation and pouring of shaping mud.

[0022] The mud regulating tank 200 is located higher than the primary mud tank 100 and the shaping mud mixing tank 300. The primary mud tank 100 is provided with a first pump body 110 connected to the mud regulating tank 200 through a pipeline. The first pump body 110 is a submersible mud pump. In this way, the blended mud in the mud regulating tank 200 can flow to the shaping mud mixing tank 300 by gravity.

[0023] The outlet pipes of the shaping slurry mixing tank 300 flow into the same pipeline. A second pump 340 is installed on the pipeline. The second pump 340 is a slurry pump or a screw pump. Depending on the actual site, the installation of the second pump 340 can be optional. The slurry can be pumped to the pouring site by a slurry pump (screw pump) or flowed by gravity.

[0024] The first valve 310 and the second valve 320 are gate valves, one of the most common valve types. The pipes connecting the primary mud tank 100, the mud conditioning tank 200, and the shaping mud mixing tank 300 are pressure pipes to ensure safe and reliable pipeline transportation. The first stirring device 210 and the second stirring device 330 are both conventional mud stirring devices, primarily consisting of a power device (such as a motor) driving stirring blades.

[0025] The basic control principle of the system is: the on-site debris (preferably the sticky soil generated by earth excavation at the construction site) is made into mud in the on-site primary mud pool for standby use. The mud blending pool and the shaping mud mixing pool are a complete set of movable equipment, which are transported to the site; the mud in the primary mud pool is pumped into the mud blending pool by the first pump body, and after blending and stirring to a certain specific gravity, the first valve downstream is opened and the mud flows into the shaping mud mixing pool by gravity; the curing agent is added according to the specific gravity and volume of the mud, and after stirring evenly, it is pumped to the casting site by the slurry pump (screw pump) or gravity flows according to the on-site terrain.

[0026] Two sets of shaping mud mixing tanks are set up to cooperate with the mud blending tank for continuous preparation and pouring. The process includes the following steps:

[0027] 1) The two first valves 310 are closed at the same time, and the first pump body 110 in the primary mud pool 100 pumps a fixed amount of primary mud into the mud blending pool 200, samples the mud and measures its specific gravity. Water or soil is added according to the specific gravity of the primary mud to adjust the designed mud gravity. After stirring evenly, the two second valves 320 are closed, and the left channel (i.e., the pipeline on the left side of the flow direction) is opened. Figure 1 The first valve 310 of the upper pipeline (corresponding to the first valve on the right pipeline) is closed, and the mud flows by gravity into the shaping mud mixing tank 300 on the left pipeline;

[0028] 2) Based on the amount of mud in the mud conditioning tank 200 and the designed mud density, a fixed amount of curing agent is added to the left shaping mud mixing tank 300. After stirring evenly, the second valve 320 downstream of the shaping mud mixing tank 300 is opened (the other second valve is closed), and the mud is pumped to the pouring site by the second pump body 340;

[0029] 3) While the shaping mud mixing tank 300 in step 2) is running, the two first valves 310 are closed at the same time, and the action of step 1) is repeated. After the mud in the mud blending tank 200 is evenly stirred, the right ( Figure 1 The second valve 320 of the lower route (in the middle position) is closed, the first valve 310 of the right route is opened (the first valve of the left route is closed), and the mud flows into the shaping mud mixing tank 300 of the right route by gravity;

[0030] 4) According to the amount of mud in the mud regulating tank 200 and the designed mud density, add a certain amount of curing agent to the shaping mud mixing tank 300 on the right side, stir evenly, and set aside;

[0031] 5) After the shaping mud in the left shaping mud mixing tank 300 is poured, the second valve 320 of the left channel is closed, and the second valve 320 of the right channel is opened to continue pouring;

[0032] 6) Repeat the above steps 1) to 5) to form a continuous pouring cycle.

[0033] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of this application should be within the scope of protection of this application.
