Description

Technical Field

[0001] The utility model relates to a backwater drainage device, in particular to a curtain grouting drilling backwater drainage device, belonging to the technical field of backwater drainage. Background Art

[0002] Generally speaking, curtain grouting is a grouting project in which slurry is poured into cracks and pores in rock or soil to form a continuous water-blocking curtain to reduce seepage and lower penetration pressure. During the curtain grouting drilling process, if the groundwater level is high, backflow is likely to occur and overflow onto the working surface. In order to ensure the normal progress of the construction, the staff needs to use drainage pipes to drain the overflowing backflow water.

[0003] At present, when workers use drainage pipes for drainage, due to the relatively simple structure of the drainage pipes, the return water flowing out during drilling usually carries rock powder and drilling debris. Therefore, during the process of drainage, the drainage pipes are easily blocked, which affects the normal drainage work.

[0004] After searching, a Chinese utility model patent with the announcement number CN208219684U discloses a curtain grouting borehole return water directional drainage device, comprising an orifice pipe with an increased pipe (3), a drainage pipe (11) and a drainage hose (1), wherein the lower end of the orifice pipe with an increased pipe (3) is provided with an external threaded section I (2) threadedly connected to the curtain grouting orifice pipe, the outer middle part of the orifice pipe with an increased pipe (3) is provided with a drainage branch (4) whose left end is welded and connected to the orifice pipe, the axis of the drainage branch (4) intersects perpendicularly with the axis of the orifice pipe with an increased pipe (3), and the right end of the drainage branch (4) is provided with a shoulder I (6) with an external thread; the left end of the drainage pipe (11) is provided with a shoulder II (9) and an internal section (7) inserted into the right end of the drainage branch (4), and a sealing gasket ( 8), the right end face of the shoulder I (6) and the left end face of the shoulder II (9) are respectively fitted with the left and right end faces of the sealing gasket (8), the drainage pipe (11) is sleeved with a swivel nut (10) threaded with the shoulder I (6), and the sealing gasket (8) and the shoulder II (9) are both located inside the swivel nut (10); the right end of the drainage pipe (11) is sleeved with the left end of the drainage hose (1), the outer side of the right end of the drainage pipe (11) is provided with a directional iron bar (14) bundled with the drainage hose (1), the right end of the drainage pipe (11) is provided with at least two parallel threaded columns (12), the lower end of the threaded column (12) is vertically welded to the outer cylindrical surface of the right end of the drainage pipe (11), and the directional iron bar (14) and the threaded column (12) are wound and fixed together. Although the device can drain the return water, it carries rock powder and drilling slag, which can easily cause blockage of the drainage pipe and the drainage hose during the process of flowing through the drainage pipe and the drainage hose, and is difficult to clean, resulting in the device being unable to play its due role.

[0005] The Chinese utility model patent with the announcement number CN219825332U discloses a curtain grouting drilling return water drainage device, which is used to be connected to a curtain grouting pipe (1), comprising: a pipe expansion tube (2), the lower end of which is connected to the upper end of the curtain grouting pipe (1); a cavity (3), wherein a filter screen (4) is arranged in the cavity (3) for dividing the cavity (3) into a raw liquid chamber (5) and a clean liquid chamber (6); a liquid inlet pipe (7) connected to the pipe expansion tube (2) for feeding liquid into the raw liquid chamber (5) is arranged on the cavity (3); and a liquid outlet pipe (8) connected to the clean liquid chamber (6) for connecting to a drainage pipe is arranged on the cavity (3). Although the above patent also achieves drainage of return water, it still has the following technical defects: the filter residue is not cleaned comprehensively and cannot be cleaned on both sides of the cavity. Long-term accumulation will lead to a decrease in the return water drainage volume, which is not conducive to the return water drainage. In short, it is often very inconvenient.

[0006] Therefore, the key to solving the above technical problems is to develop a curtain grouting drilling return water drainage device with strong practicality and high working reliability. Summary of the invention

[0039] The working principle is: when the curtain grouting drilling return water drainage device of the above-mentioned design structure is used, the operator only needs to carry the utility model to the designated working position by hand or with corresponding equipment to wait for installation as a standby.

[0040] During installation, the operator only needs to install the supporting water inlet pipe (8) of the utility model on the connecting pipe (2) through the bolt assembly. Specifically, during installation, the operator uses a plurality of bolts to sequentially penetrate the various connecting holes provided in an annular manner on the flange (21) and the various mounting holes provided in an annular manner on the mounting member (81), and then tightens the ends through nuts to connect the supporting water inlet pipe (8) and the connecting pipe (2) into an integral structure; at the same time, the drainage pipe (9) is installed on the treatment box body (1) at the water outlet of the treatment box body on the right side, and the water inlet pipe (8) can be used after the connection is completed.

[0041] When in use, the return water in the external drilling hole enters the interior of the processing box body (1) from the water inlet of the processing box body through the supporting water inlet pipe (8), and then passes through the filter element (3) arranged at the water outlet of the processing box body on the right side of the processing box body (1), thereby blocking the entry of foreign matter in the water and collecting it in the interior of the processing box body (1), and the filtered return water can be smoothly drained through the drainage pipe (9);

[0042] During use, the amount of debris collected inside the treatment box body (1) can be observed through the observation port (411) provided inside the sealing plate (41). When a large amount of debris is observed to be collected, the staff only needs to manually close the valve (22) provided on the connecting pipe (2) to stop the water flow of the supporting water inlet pipe (8) of the utility model, so as to seal the water inlet of the treatment box body; then the staff pulls up the connecting strip (52), thereby driving the two sets of limiting strips (53) to move upward and be pulled out from the limiting holes (13) at the top of the treatment box body (1); then the staff pulls the handle (42), thereby driving the sealing plate (41) together with the connecting rod (7), so that the pushing plate (6) in contact with the inner wall of the treatment box body (1) is forced to move inside the treatment box body (1), and the debris collected inside the treatment box body (1) is pushed out to the opening on the front of the treatment box body (1), so as to clean the debris inside the treatment box body (1).

[0043] After the work of pushing the debris out of the processing box body (1) is completed, the staff pushes the handle (42) to close the processing box body (1), so that the push plate (6) is driven by the connecting rod (7) to contact and fit with the inner wall of the processing box body (1); then the staff locks the sealing assembly (4) to the processing box body (1) through the limiting mechanism (5), and the operator pulls the connecting strip (52) upwards to push the sealing plate (41) to close the opening of the processing box body (1). When the limiting connecting plate through hole on the limiting connecting plate (51) coincides with the limiting hole (13), the operator The staff loosens the connecting strip (52), and the connecting strip (52) is driven to retract downward under the elastic action of the spring (54), thereby driving the lower end of the limiting strip (53) to be clamped in the limiting hole (13), thereby completing the sealing of the processing box body (1) and the sealing plate (41). Finally, the staff can open the valve (22) provided on the connecting pipe (2), thereby opening the water inlet of the processing box body (1), so that the water can flow smoothly, and the drainage work can be ensured to proceed smoothly. The above operations are repeated in sequence until the drainage work of all the curtain grouting drilling holes is completed.

[0044] During the entire operation process described above, the valve (22) is a manual valve or an automatic electric valve, which is used to close the water flow supporting the water inlet pipe (8) and stop the supply of water to the processing box body (1).

[0045] Finally, as time goes by, when the utility model is used up, the operator only needs to clean and repair the various components of the utility model, and then move them to the designated tool storage warehouse for storage by manual or corresponding equipment, so as to prepare for the next cycle of use.

[0047] 1. The outer end of the guide groove provided in the utility model is provided with a stopper, and the stability of the sealing plate during the pulling process can be ensured by the mutual cooperation between the guide rod and the guide groove. In addition, since the guide rod is set in a T shape and the front opening of the guide groove is small, the guide rod can be effectively prevented from being completely pulled out of the guide groove, so as to prevent the sealing plate and the processing box body from being separated;

[0048] 2. The limit strip provided in the utility model can pass through the limit connecting plate and then be clamped in the limit hole to complete the sealing of the processing box body and the sealing plate. At the same time, under the elastic action of the spring, the limit strip can be firmly clamped on the processing box body and the limit connecting plate to prevent the processing box body and the sealing plate from loosening;

[0049] 3. The connecting pipe and valve provided in the utility model cooperate with each other to realize the opening or sealing of the water inlet of the treatment box body, so that the drainage operation can be interrupted during the process of the staff cleaning the inside of the treatment box body to prevent the debris in the water from accumulating in front of the push plate, so as to facilitate the staff to carry out the cleaning work;

[0111] Before use, the operator only needs to carry the utility model to a designated working position manually or with corresponding carrying equipment to wait for installation as a standby.

[0112] When in use, the return water in the external drilling hole enters the inside of the treatment box body 1 from the water inlet of the treatment box body through the supporting water inlet pipe 8, and the filter element 3 arranged at the water outlet of the treatment box body on the right side of the treatment box body 1 can block the entry of debris in the water and collect it into the inside of the treatment box body 1, and the filtered return water can be smoothly drained through the drainage pipe 9;

[0113] During use, the amount of debris collected inside the processing box body 1 can be observed through the observation port 411 provided inside the sealing plate 41. When a large amount of debris is observed to be collected, the valve 22 is used to seal the water inlet of the processing box body; then the staff pulls up the connecting strip 52, thereby driving the two sets of limit strips 53 to move upward and withdraw them from the limit holes 13 at the top of the processing box body 1, and then the staff pulls the handle 42, thereby driving the sealing plate 41 together with the connecting rod 7, so that the pushing plate 6 in contact with the inner wall of the processing box body 1 is forced to move inside the processing box body 1, and the debris collected inside the processing box body 1 is pushed out to the opening on the front side of the processing box body 1, so as to clean the debris inside the processing box body 1.

[0114] After the work of pushing the debris out of the processing box body 1 is completed, the staff pushes the handle 42 to close the processing box body 1, so that the push plate 6 is driven by the connecting rod 7 to contact and fit with the inner wall of the processing box body 1 again; then the staff locks the sealing assembly 4 to the processing box body 1 through the limiting mechanism 5, and the operator pulls up the connecting strip 52 to push the sealing plate 41 to close the opening of the processing box body 1. When the limiting connecting plate through hole on the limiting connecting plate 51 coincides with the limiting hole 13, the operator releases the connecting strip 52 to close the sealing plate 41 to the opening of the processing box body 1. The connecting strip 52 is driven to retract downward under the elastic action of the spring 54, thereby driving the lower end of the limiting strip 53 to be clamped in the limiting hole 13, thereby completing the sealing of the processing box body 1 and the sealing plate 41. Finally, the staff can open the valve 22 set on the connecting pipe 2 to open the water inlet of the processing box body 1, so that the water can flow smoothly. At this time, the smooth progress of the drainage work can be guaranteed, and the above operations are repeated in sequence until the return water drainage work of all curtain grouting drilling holes is completed.

[0115] Finally, as time goes by, when the utility model is used up, the operator only needs to clean and repair the various components of the utility model, and then move them to the designated tool storage warehouse for storage by manual or corresponding equipment, so as to prepare for the next cycle of use.

[0116] Finally, it should be noted that the above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
