Description

Technical Field

[0001] This invention relates to the field of mud preparation technology, and more particularly to a mud treatment system and method. Background Technology

[0002] During the drilling of bored piles, the soil layer to be drilled is often loose (or the soil around the borehole is disturbed during drilling, or the soil's self-stabilizing ability is weak). Therefore, under horizontal earth pressure, the soil around the borehole tends to collapse into the hole. Without mud slurry for wall protection, this soil will collapse and fall into the borehole, blocking it and preventing drilling. Thus, controlling the mud slurry's properties is crucial for ensuring construction quality. However, when using mud slurry for wall protection on large construction sites, the preparation, circulation, transportation, and waste disposal of the mud slurry are difficult to manage in a timely manner. Conventional mud slurry treatment methods are insufficient to meet construction requirements under large-scale conditions, making it difficult to guarantee mud slurry quality, affecting project quality, and easily leading to indiscriminate mud discharge and environmental pollution.

[0003] Therefore, there is an urgent need for a mud treatment system and method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a mud treatment system and method to solve the problems of low efficiency in mud preparation, circulation and transportation, ineffective quality assurance, and untimely and environmentally unfriendly waste mud treatment.

[0025] A slurry delivery tank, which is connected to the storage tank and the third new slurry pipe;

[0026] A third pump is installed on the slurry delivery tank, and the third pump can pump the new slurry into the third new slurry pipe.

The sand separated by the second desanding machine enters the sand box, and the separated circulating slurry flows into the first new slurry tank through the first new slurry pipe to mix with the new slurry.

[0040] The beneficial effects of this invention are:

[0041] The mud treatment system provided by this invention, by setting up a mud treatment module, can immediately pump the waste mud and circulating mud generated during pile foundation construction to the mud treatment module via the first waste mud pipe and the first circulating mud pipe, respectively, so that the waste mud and circulating mud generated during pile foundation construction are treated in a timely and effective manner to ensure the construction quality of the pile foundation.

[0057] like Figures 1 to 5 As shown, this embodiment provides a mud treatment system, including a mud treatment module 1, a transfer module 2, and a mud-making module 3. The mud treatment module 1 is connected to the pile foundation 100 via a first waste mud pipe 11, a first circulating mud pipe 12, and a first new mud pipe 13; the transfer module 2 is connected to the mud treatment module 1 via a second waste mud pipe 21, a second circulating mud pipe 22, and a second new mud pipe 23; and the mud-making module 3 is connected to the transfer module 2 via a third waste mud pipe 31, a third circulating mud pipe 32, and a third new mud pipe 33.

[0058] The mud treatment system provided in this embodiment, by setting up a mud treatment module 1, can immediately pump the waste mud and circulating mud generated during the construction of the pile foundation 100 into the mud treatment module 1 via the first waste mud pipe 11 and the first circulating mud pipe 12, respectively, so that the waste mud and circulating mud generated during the construction of the pile foundation 100 can be treated in a timely and effective manner to ensure the construction quality of the pile foundation 100; by setting up a transfer module 2, the waste mud and circulating mud in the mud treatment module 1 can be pumped into the transfer module 2 via the second waste mud pipe 21 and the second circulating mud pipe 22, respectively, to alleviate the storage pressure of the mud treatment module 1. Through the slurry-making module 3, the waste slurry and circulating slurry in the transfer module 2 can be pumped to the slurry-making module 3 via the third waste slurry pipe 31 and the third circulating slurry pipe 32, respectively. The slurry-making module 3 treats the waste slurry to prevent environmental pollution. In addition, the circulating slurry can be converted into new slurry through the slurry-making module 3, and then sequentially delivered to the pile foundation 100 for grouting through the third new slurry pipe 33, the second new slurry tank 26, the second new slurry pipe 23, the first new slurry tank 143, and the first new slurry pipe 13. This ensures the quality of the slurry and effectively improves the delivery efficiency of the new slurry, meeting the construction requirements of the pile foundation 100.

[0059] Optionally, such as Figure 2 As shown, the mud treatment module 1 includes a mud storage tank 14, which contains a first waste mud tank 141, a first circulating mud tank 142, and a first new mud tank 143. The first waste mud tank 141 is connected to the first waste mud pipe 11 and the second waste mud pipe 21. The first circulating mud tank 142 is connected to the first circulating mud pipe 12 and the second circulating mud pipe 22. The first new mud tank 143 is connected to the first new mud pipe 13 and the second new mud pipe 23. It is understood that waste mud generated during the construction of the pile foundation 100 can be promptly discharged through the first waste mud pipe 11 and temporarily stored in the first waste mud tank 141. Circulating mud generated during the construction of the pile foundation 100 can be promptly discharged through the first circulating mud pipe 12 and temporarily stored in the first circulating mud tank 142. New mud generated by the mud-making module 3 can flow to the first new mud tank 143 through the second new mud pipe 23 and then be pumped to the construction site of the pile foundation 100 through the first new mud pipe 13 to ensure timely replenishment of new mud during construction.

[0060] Specifically, in this embodiment, the mud storage tank 14 is composed of steel plates connected together, with a wall thickness of not less than 10mm, a height of not less than 1m, and a total volume of 30m³. 3 Furthermore, the first waste slurry tank 141, the first circulating slurry tank 142, and the first new slurry tank 143 are all the same size to ensure effective storage of waste slurry and circulating slurry. In addition, in this embodiment, the first new slurry tank 143 includes six new slurry pumping tanks of the same size, and the height of a single new slurry pumping tank does not exceed 3m. New slurry is stored in the new slurry pumping tanks, thereby enabling the new slurry to be stored in blocks to ensure the quality of the new slurry.

[0061] Optionally, such as Figure 3 As shown, the transfer module 2 includes a second waste slurry tank 24, a second circulating slurry tank 25, a second new slurry tank 26, and a first pump 27. The second waste slurry tank 24 is connected to the second waste slurry pipe 21 and the third waste slurry pipe 31; the second circulating slurry tank 25 is connected to the second circulating slurry pipe 22 and the third circulating slurry pipe 32; the second new slurry tank 26 is connected to the second new slurry pipe 23 and the third new slurry pipe 33; the second waste slurry pipe 21, the second circulating slurry pipe 22, and the second new slurry pipe 23 are all equipped with the first pump 27. Understandably, the transfer module 2 serves as a transfer point for waste slurry and circulating slurry. The waste slurry in the first waste slurry tank 141 flows sequentially through the second waste slurry pipe 21, the second waste slurry tank 24, and the third waste slurry pipe 31 to the pulping module 3 for treatment, in order to prevent the waste slurry from polluting the environment. The circulating slurry in the first circulating slurry tank 142 flows sequentially through the second circulating slurry pipe 22, the second circulating slurry tank 25, and the third circulating slurry pipe 32 to the pulping module 3 for further processing, converting it into usable new slurry, thereby enabling the reuse of mud and saving resources.

[0062] Optionally, such as Figure 3 As shown, the third waste slurry pipe 31, the third circulating slurry pipe 32, and the third new slurry pipe 33 are all equipped with a second pump 28. It can be understood that the second pump 28 is set up as a backup pump so that if the first pump 27 fails, the waste slurry, circulating slurry, and new slurry can be transported through the second pump 28 to ensure the continuity of operation.

[0063] Specifically, in this embodiment, the volumes of the second waste slurry tank 24, the second circulating slurry tank 25, and the second new slurry tank 26 are all not less than 100m³. 3 To ensure sufficient storage capacity for waste slurry, circulating slurry, and fresh slurry. The power of the first pump 27 and the second pump 28 is not less than 40kW to ensure the conveying efficiency of waste slurry, circulating slurry, and fresh slurry; the inner diameter of the pipes of the second waste slurry pipe 21, the third waste slurry pipe 31, the second circulating slurry pipe 22, the third circulating slurry pipe 32, the second fresh slurry pipe 23, and the third fresh slurry pipe 33 is not less than 300mm to ensure a high conveying capacity for waste slurry, circulating slurry, and fresh slurry, further ensuring conveying efficiency.

[0064] Optionally, such as Figure 4 and Figure 5As shown, the slurry preparation module 3 includes a new slurry generation mechanism 34 and a waste slurry treatment mechanism 35. The new slurry generation mechanism 34 is connected to the third circulating slurry pipe 32 and the third new slurry pipe 33, and the waste slurry treatment mechanism 35 is connected to the third waste slurry pipe 31. The new slurry generation mechanism 34 can convert the circulating slurry into new slurry that meets the required specifications for use in the construction of the pile foundation 100; the waste slurry treatment mechanism 35 can separate the waste slurry from the sediment, reducing environmental pollution. Specifically, in this embodiment, the new slurry generation mechanism 34 and the waste slurry treatment mechanism 35 are separate and do not interfere with each other during operation, to prevent the waste slurry from mixing with the circulating slurry and affecting the quality of the new slurry.

[0065] Optionally, such as Figure 4 As shown, the new pulp generation mechanism 34 includes:

[0066] The first desanding machine 341 is connected to the third circulating slurry pipe 32.

[0067] Sand and soil pool 342 is used to collect the sand and soil separated by the first sand removal machine 341.

[0068] The transfer pool 343 is connected to the first sand remover 341, and the top of the transfer pool 343 is provided with an opening.

[0069] Sedimentation tank 344 is connected to transfer tank 343 through an opening.

[0070] Adjustment tank 345 is connected to sedimentation tank 344.

[0071] The pulping tank 346 is used to produce artificial fresh pulp. The artificial fresh pulp in the pulping tank 346 can be pumped to the conditioning tank 345 by a pump to mix with the circulating pulp to produce fresh pulp.

[0072] Storage tank 347 is connected to adjustment tank 345 to transfer new pulp from adjustment tank 345 to storage tank 347.

[0073] The slurry delivery tank 348 is connected to the storage tank 347 and the third new slurry pipe 33.

[0074] The third pump 349 is installed on the slurry delivery tank 348 and can pump new slurry into the third new slurry pipe 33.

[0075] Understandably, the circulating slurry in the second circulating slurry tank 25 is transported to the first desander 341 via the third circulating slurry pipe 32 for desanding. The sand separated by the first desander 341 enters the sand tank 342 and is transported out by dump trucks. The separated circulating slurry flows to the transfer tank 343 for fine sand sedimentation. Since the first desander 341 can remove larger sand particles, the smaller fine sand particles, along with the circulating slurry, pass through the opening at the top of the transfer tank 343 and settle in the sedimentation tank 344. The sedimentation tank 344 also has an opening at the top of its wall, with a height and width of 15cm. The circulating slurry in the sedimentation tank 344 then flows into the adjustment tank 345 through the opening at the top of the sedimentation tank 344. At this point, the circulating slurry flowing out from the opening at the top of the sedimentation tank 344 no longer contains fine sand, and the artificial fresh slurry in the slurry-making tank 346 can be pumped out by a pump. The slurry is mixed with circulating slurry in the adjustment tank 345 to prepare new slurry that meets the requirements. The new slurry flows into the storage tank 347 for storage and later use. The slurry delivery tank 348 is connected to the storage tank 347 and the third new slurry pipe 33. When new slurry is needed at pile foundation 100, the new slurry in the storage tank 347 flows to the slurry delivery tank 348 and is pumped to the third new slurry pipe 33 by the third pump 349. The new slurry flows sequentially through the third new slurry pipe 33, the second new slurry tank 26, the second new slurry pipe 23, the first new slurry tank 143, and the first new slurry pipe 13 to reach pile foundation 100 for grouting. Specifically, in this embodiment, the first desander 341 should have a mud processing capacity of not less than 500m³. 3 / d. The power of the third pump, 349, shall not be less than 300kW.

[0076] Optionally, such as Figure 5 As shown, the waste slurry treatment unit 35 includes:

[0077] Waste slurry tank 351 is connected to the third waste slurry pipe 31.

[0078] Clear water tank 352 is located on one side of waste slurry tank 351.

[0079] Slag pit 353 is located on the other side of waste slurry pit 351.

[0080] The filter press 354 can filter the waste slurry in the waste slurry tank 351 to form slag and clean water. The slag falls into the slag tank 353, and the clean water flows into the clean water tank 352.

[0081] Understandably, the third waste slurry pipe 31 transports the waste slurry to the waste slurry tank 351, and a certain pressure is applied to the waste slurry through the filter press 354, causing the sand and water in the waste liquid to separate. The separated slag enters the slag tank 353 and is transported out by dump trucks; the separated clean water flows into the clean water tank 352, which can be directly used for site vehicle washing, road cleaning, and other work, improving the utilization rate of the waste liquid. Specifically, the filter press 354 in this embodiment is existing technology and will not be described in detail here. Furthermore, the sand tank 342 in this embodiment is made of concrete, with a height of 3m and a bottom area of ​​20m². 2 .

[0082] Optionally, such as Figure 2 As shown, the mud treatment module 1 is also equipped with a second desander 15 and a sand box 16. The second desander 15 is connected to the first circulating slurry pipe 12 and the first new slurry pipe 13. The sand box 16 is used to collect the sand separated by the second desander 15. Understandably, the second desanding machine 15 and sand tank 16 are not routinely used. However, due to the large construction site in this embodiment and the large amount of circulating slurry generated at pile foundation 100, when the efficiency of the new slurry generation mechanism 34 in converting circulating slurry into new slurry is less than the efficiency of the circulating slurry generated at pile foundation 100, the second desanding machine 15 and sand tank 16 can be activated to directly transport the circulating slurry generated at pile foundation 100 to the second desanding machine 15 through the first circulating slurry pipe 12. The second desanding machine 15 removes sand from the circulating slurry, and the sand separated by the second desanding machine 15 enters the sand tank. The separated circulating slurry flows through the first new slurry pipe 13 into the first new slurry tank 143 to mix with the new slurry, and then is pumped to the construction site of pile foundation 100 through the first new slurry pipe 13 to relieve the pressure on the new slurry generation mechanism 34. Specifically, in this embodiment, the second desanding machine 15 has a mud processing capacity of not less than 100m³. 3 / d.

[0083] Furthermore, this embodiment also provides a mud treatment method using the aforementioned mud treatment system, comprising:

[0084] Step S1: The waste slurry generated at pile foundation 100 is pumped to the first waste slurry tank 141 in real time via the first waste slurry pipe 11, and the circulating slurry generated at pile foundation 100 is pumped to the first circulating slurry tank 142 via the first circulating slurry pipe 12.

[0085] Step S2: The waste slurry in the first waste slurry tank 141 is transported to the second waste slurry tank 24 via the first pump 27 and the second waste slurry pipe 21. The circulating slurry in the first circulating slurry tank 142 is transported to the second circulating slurry tank 25 via the first pump 27 and the second circulating slurry pipe 22.

[0086] Step S3: The waste slurry in the second waste slurry tank 24 is transported to the waste slurry treatment mechanism 35 via the third waste slurry pipe 31. The waste slurry in the waste slurry pool 351 is filtered by the filter press 354 to form slag and clean water. The slag falls into the slag pool 353, and the clean water flows into the clean water pool 352. The circulating slurry in the second circulating slurry tank 25 is transported to the new slurry generation mechanism 34 via the third circulating slurry pipe 32. Sand is removed by the first sand remover 341. The sand separated by the first sand remover 341 enters the sand pool 342. The separated circulating slurry passes through the transfer pool 343 and the sedimentation pool 344 in sequence and then enters the adjustment pool 345. The artificial new slurry produced by the slurry making pool 346 is pumped into the adjustment pool 345 and mixed with the circulating slurry to form new slurry. Then the new slurry is transported to the storage pool 347 for later use.

[0087] Step S4: When new grout is needed at pile foundation 100, the new grout in storage tank 347 is transported to grout delivery tank 348, and then pumped to the third new grout pipe 33 by the third pump 349. The new grout flows sequentially through the third new grout pipe 33, the second new grout tank 26, the second new grout pipe 23, the first new grout tank 143, and the first new grout pipe 13 to reach pile foundation 100 for grouting.

[0088] The mud treatment method provided in this embodiment can promptly remove the waste mud and circulating mud generated during the construction of the pile foundation 100, preventing adverse effects on the construction quality of the pile foundation 100. The waste mud can be treated by the waste mud treatment device 35 to form slag and clean water, effectively preventing the waste mud from polluting the environment. The circulating mud can be converted into new mud by the new mud generation device 34 for recycling, which not only effectively saves resources, but also ensures the quality of the new mud through the new mud generation device 34, thereby meeting the construction requirements of the pile foundation 100.

[0089] Optionally, in step S3, when the efficiency of the new slurry generation mechanism 34 in converting the circulating slurry into new slurry is less than the efficiency of the circulating slurry generated at the pile foundation 100, the second desander 15 is activated, and part of the circulating slurry in the first circulating slurry pipe 12 is transported to the second desander 15 for desanding. The sand separated by the second desander 15 enters the sand box, and the separated circulating slurry flows into the first new slurry tank 143 through the first new slurry pipe 13 to mix with the new slurry.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention.
