Description

Technical Field

[0001] The invention 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 invention patent with the publication number CN208219684U discloses a curtain grouting borehole return water directional drainage device, comprising an orifice pipe with an increased diameter (3), a drainage pipe (11) and a drainage hose (1), wherein the lower end of the orifice pipe with an increased diameter (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 diameter (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 diameter (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) is sleeved on the internal section (7). ), 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 invention patent with the publication number CN219825332U discloses a curtain grouting drilling water return drainage device, which is used to be connected to a curtain grouting pipe (1), and includes: a heightening pipe (2), the lower end of the heightening pipe (2) is connected to the upper end of the curtain grouting pipe (1); a cavity (3), a filter screen (4) for dividing the cavity (3) into a raw liquid chamber (5) and a purified liquid chamber (6) is arranged in the cavity (3), and a liquid inlet pipe (7) for connecting to the heightening pipe (2) and feeding liquid into the raw liquid chamber (5) is arranged on the cavity (3); an outlet pipe (8) communicating with the purified liquid chamber (6) and used for connecting a drainage pipe is arranged on the cavity (3). Although the above patent also realizes the drainage of the returned water, there are still the following technical defects: the filter residue is not comprehensively cleaned, and the two sides of the cavity cannot be cleaned. Long-term accumulation will lead to a decrease in the water return drainage volume, which is not conducive to the water return 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 water return drainage device with strong practicability and high working reliability. Summary of the Invention

[0086] Further, as Figure 5 shown, guide grooves 12 for cooperating with the sealing assembly 4 to complete the work are opened on both sides of the lower end of the processing cartridge 1, and stoppers are also arranged at the ends of the guide grooves 12, and among them, sealing grooves adapted to the sealing assembly 4 are also opened at the upper ends of both side plates at the opening of the processing cartridge 1.

[0087] Further, as Figure 2 shown, a limiting hole 13 adapted to the limiting mechanism 5 is also opened on the top plate at the open end of the processing cartridge 1, and among them, mounting plates adapted to the support inlet pipe 8 and the drainage pipe 9 are respectively connected to the processing cartridge 1 outside the processing cartridge water inlet and the processing cartridge water outlet.

[0088] Further, as Figure 4 shown, the sealing device 2 includes:

[0089] The plugging plate 21 is slidably clamped on the sliding groove 11;

[0090] The adjusting screw rod 22, one end of the adjusting screw rod 22 is connected to the plugging plate 21 through a bearing, and the upper section of the adjusting screw rod 22 is threadedly connected in the threaded groove of the treatment box body 1;

[0091] The rotating member 23 is connected to the other end of the adjusting screw rod 22 and is located above the treatment box body 1. Among them, the cross-sectional area of the plugging plate 21 is larger than the cross-sectional area of the water inlet of the treatment box body.

[0092] In the present invention, the lower end of the adjusting screw rod 22 is connected to the inner ring of the bearing, and the upper end of the plugging plate 21 is connected to the outer ring of the bearing; the sliding groove 11 is arranged in a rectangle, so as to effectively prevent the plugging plate 21 from idling inside the sliding groove 11. Through the mutual cooperation of the adjusting screw rod 22 and the plugging plate 21, the opening or sealing of the water inlet of the treatment box body can be realized, so that the drainage operation can be interrupted during the process of the staff cleaning the inside of the treatment box body 1, so as to prevent sundries in the water from accumulating in front of the pushing plate 6, which is beneficial to the staff to carry out the cleaning work.

[0093] Further, as Figure 5 shown, the sealing assembly 4 includes:

[0094] The sealing plate 41 is used to be connected to the treatment box body 1 to complete the sealing;

[0095] The handle 42 is arranged on the outer side of the sealing plate 41;

[0096] The guide rods 43 are symmetrically connected to both ends of the lower part of the inner side of the sealing plate 41, and the guide rods 43 are correspondingly slidably clamped in the guide grooves 12.

[0097] In the present invention, the handle 42 is arranged in the middle of the lower part of the outer side of the sealing plate 41; through the arrangement of the handle 42, it is convenient for the staff to pull the sealing plate 41. Through the arrangement of the observation port 411, it is convenient for the staff to penetrate the collection amount of sundries inside the treatment box body 1 and carry out the cleaning work in time.

[0098] Specifically, as Figure 5 shown, the sealing plate 41 is also provided with an observation port 411, and the observation port 411 is arranged along the height direction of the sealing plate 41;

[0099] The cross-section of the guide rod 43 is in a "T" shape;

[0100] Among them, sealing blocks 44 adapted to the sealing grooves of the treatment box body 1 are also arranged above both ends of the inner side of the sealing plate 41.

[0101] In the present invention, the sealing plate 41 at the observation port 411 is made of a transparent material, facilitating the observation of the debris inside the processing box body 1; a sealing block 44 is connected to the inner side of the sealing plate 41 and is adapted to be connected to the sealing groove opened on the front surface of the processing box body 1, and the sealing groove and the sealing block 44 are arranged in a loop structure. During use, through the loop structure of the sealing block 44 and the sealing groove, the sealing effect of the sealing plate 41 on the front opening of the processing box body 1 can be effectively ensured, so as to effectively prevent water leakage during the drainage process.

[0102] In the present invention, the cross-section of the guide rod 43 is arranged in a T-shaped structure, and a guide groove 12 adapted to the guide rod 43 is opened on the outer side wall of the processing box body 1, and the front opening of the guide groove 12 is smaller than the back opening, that is, a stop block is provided at the outer end of the guide groove 12. Through the mutual cooperation of the guide rod 43 and the guide groove 12, the stability of the sealing plate 41 during the pulling process can be ensured. In addition, since the guide rod 43 is arranged in a T-shape and the front opening of the guide groove 12 is smaller, the guide rod 43 can be effectively prevented from being completely pulled out of the inside of the guide groove 12, so as to prevent the separation of the sealing plate 41 and the processing box body 1.

[0103] Further, as Figure 6 and Figure 7 shown, the limiting mechanism 5 includes:

[0104] A limiting connecting plate 51, one side of the limiting connecting plate 51 is connected above the sealing plate 41, and a through hole of the limiting connecting plate corresponding to the limiting hole 13 is opened on the limiting connecting plate 51;

[0105] A connecting strip 52, the connecting strip 52 is located above the limiting connecting plate 51;

[0106] Limiting strips 53, the limiting strips 53 are symmetrically connected to the two lower ends of the connecting strip 52;

[0107] A spring 54, the spring 54 is connected between the limiting connecting plate 51 and the connecting strip 52;

[0108] Wherein, the lower end of the limiting strip 53 is connected to the corresponding through hole of the limiting connecting plate below; one end of the spring 54 is connected to the middle part below the connecting strip 52, and the other end of the spring 54 is connected to the limiting connecting plate 51.

[0109] In the present invention, the limiting strip 53 passes through the limiting connecting plate 51 and is clamped in the limiting hole 13 to complete the sealing of the processing box body 1 and the sealing plate 41; under the elastic action of the spring 54, the limiting strip 53 can be prevented from being lost after being pulled out from the limiting connecting plate 51 at the top of the sealing plate 41, and through the elastic characteristics of the spring 54 itself, the tightness of the limiting strip 53 clamped inside the processing box body 1 can be ensured.

[0110] Further, the filter element 3 is a filter screen, and the filter element 3 is connected to the outlet of the treatment box body 1 inside the treatment box body 1 through a fastener.

[0111] The principle is as follows: The spring 54 is fixedly connected between the limit connecting plate 51 and the connecting bar 52; when locking and limiting, the operator pulls up the connecting bar 52 to push the sealing plate 41 to close towards the opening of the treatment box body 1. When the through hole of the limit connecting plate on the limit connecting plate 51 coincides with the limit hole 13, the operator releases the connecting bar 52. Under the elastic action of the spring 54, the connecting bar 52 drives the connecting bar 52 to retract downward, and then drives the lower end of the limit bar 53 to be clamped in the limit hole 13 to complete the sealing of the treatment box body 1 and the sealing plate 41.

[0112] Before using a curtain grouting drilling water return drainage device with the above design structure, the operator only needs to manually or by using corresponding handling equipment to move the present invention to a designated working position for standby installation.

[0113] During installation, the operator only needs to install the support water inlet pipe 8 of the present invention at the water inlet of the treatment box body 1 of the present invention, and install the drainage pipe 9 of the present invention at the water outlet of the treatment box body 1 of the present invention. After the installation is stable and reliable, it can be used.

[0114] During use, the water return in the external drilling enters the inside of the treatment box body 1 from the water inlet of the treatment box body through the support water inlet pipe 8. After passing through the filter element 3 arranged at the water outlet of the right side of the treatment box body 1, the sundries in the water can be blocked and collected inside the treatment box body 1, and the filtered water return can be smoothly drained through the drainage pipe 9;

[0115] During the use process, through the observation port 411 arranged inside the sealing plate 41, the collection amount of sundries inside the treatment box body 1 can be observed. When it is observed that the collection amount of sundries is relatively large, the staff rotates the rotating member 23, thereby driving the adjusting screw 22 to rotate, so that the bottom end thereof drives the plugging plate 21 connected by a bearing to move downward and contact the inner wall of the water inlet of the treatment box body to achieve the sealing of the water inlet of the treatment box body; then the staff pulls up the connecting bar 52, thereby driving the upper movement of the two limit bars 53 and pulling them out from the limit holes 13 at the top of the treatment box body 1. Subsequently, the staff pulls the handle 42, thereby driving the sealing plate 41 together with the connecting rod 7 to be pulled, so that the pushing plate 6 in contact connection with the inner wall of the treatment box body 1 moves inside the treatment box body 1 and pushes the sundries collected inside the treatment box body 1 to the opening at the front of the treatment box body 1 to achieve the cleaning of the sundries inside the treatment box body 1.

[0116] After finishing the work of pushing the sundries out of the processing box body 1, the staff closes the pushing handle 42 with the processing box body 1, so that the pushing plate 6 drives the pushing plate 6 to contact and fit with the inner wall of the processing box body 1 again through the connecting rod 7; then the staff locks and connects the sealing component 4 to the processing box body 1 through the limiting mechanism 5. The operator pulls up the connecting strip 52 upward, closes the pushing sealing plate 41 towards the opening of the processing box body 1. When the through hole of the limiting connecting plate on the limiting connecting plate 51 coincides with the limiting hole 13, the operator releases the connecting strip 52. Under the elastic action of the spring 54, the connecting strip 52 drives the connecting strip 52 to retract downward, and then drives the lower end of the limiting strip 53 to be clamped in the limiting hole 13, completing the sealing of the processing box body 1 and the sealing plate 41. Finally, the staff can reversely rotate the rotating part 23, which can drive the upper lifting of the blocking plate 21. At this time, the smooth progress of the drainage work can be ensured. Sequentially cycle the above operations until the operation of the present invention is completed.

[0117] Finally, as time goes by, after the present invention is used up, the operator only needs to clean and repair each component of the present invention, and then transport it to the designated tool storage warehouse for storage by manual or corresponding handling equipment for storage, so as to be used for the next cycle.

[0118] Embodiment 2

[0119] This Embodiment 2 is basically the same as Embodiment 1. The only differences are: the shape and structure design of the blocking device are different from those in Embodiment 1; at the same time, it is also different that at the position where the connecting pipe 2a is connected to the processing box body 1, there is no connecting flange or connecting plate, but the connecting pipe 2a of the present invention is directly communicated with the water inlet of the processing box body 1 of the present invention to realize the water transmission function.

[0120] Specifically, the differences are mainly manifested in that the blocking device includes:

[0121] A connecting pipe 2a, one end of the connecting pipe 2a is connected and communicated to the processing box body 1 at the water inlet of the processing box body, and the other end is connected with a flange 2b, and the flange 2b is connected to support the water inlet pipe 8;

[0122] A valve 2c, which is installed on the connecting pipe 2a to control the opening or closing of the water in the supporting water inlet pipe 8.

[0123] The connecting pipe 2a is an integral hollow cylindrical member, which is used to be matched and communicated with the supporting water inlet pipe 8 of the present invention to realize the function of water flow circulation;

[0124] The flange 21 is annularly connected to the free end port of the connecting pipe 2a and integrated with it; several connecting holes are annularly formed in the flange 21, and the connecting holes penetrate through the front and back sides of the flange 21; it is used for bolts to pass through to connect the connecting pipe 2a of the present invention and the supporting water inlet pipe 8, achieving the functional purposes of convenient installation and convenient disassembly.

[0125] More specifically, a mounting member 81 is connected to the supporting water inlet pipe 8. The mounting member 81 is a flange, and several mounting holes are annularly and penetratingly formed in the flange. The mounting holes correspond to the connecting holes on the flange 21 and are used to connect the connecting pipe 2a of the present invention and the supporting water inlet pipe 8.

[0126] The supporting water inlet pipe 8 and the connecting pipe 2a are detachably connected into a whole through a plurality of locking components.

[0127] In the present invention, the locking component includes a bolt and a nut. The nut is fixedly fastened to the end of the bolt. During use, after the bolt sequentially passes through each of the connecting holes annularly formed in the flange 21 and each of the mounting holes annularly and penetratingly formed in the mounting member 81, the end is tightened and fixed by the nut, so as to connect the supporting water inlet pipe 8 and the connecting pipe 2a into a whole structure, realizing the function of water transmission of the present invention and achieving the purpose of diverting water.

[0128] When a curtain grouting drilling water return diversion device with the design structure of this Embodiment 2 is in use, the operator only needs to manually or by corresponding equipment carry the present invention to a designated working position for standby installation.

[0129] During installation, the operator only needs to install the supporting water inlet pipe 8 of the present invention on the connecting pipe 2a through a bolt assembly. Specifically, during installation, the operator uses a plurality of bolts to sequentially pass through each of the connecting holes annularly formed in the flange 21 and each of the mounting holes annularly and penetratingly formed in the mounting member 81, and then the end is tightened and fixed by the nut, so as to connect the supporting water inlet pipe 8 and the connecting pipe 2a into a whole structure; at the same time, the drainage pipe 9 is installed at the water outlet of the right processing box body 1 of the processing box body. After the connection is completed, it can be used.

[0130] During use, the water return in the external drilling enters the interior of the processing box body 1 from the water inlet of the supporting water inlet pipe 8. After passing through the filtering member 3 provided at the water outlet of the right processing box body of the processing box body 1, the sundries in the water can be blocked and collected inside the processing box body 1, and the filtered water return can be smoothly diverted through the drainage pipe 9.

[0131] During use, through the observation port 411 provided inside the sealing plate 41, the collection amount of sundries inside the treatment box body 1 can be observed. When it is observed that the collection amount of sundries is relatively large, the staff only needs to manually close the valve 22 provided on the connecting pipe 2a to stop the water flow in the support water inlet pipe 8 of the present invention, so as to seal the water inlet of the treatment box body; then the staff pulls up the connecting bar 52, thereby driving the upward movement of the two sets of limiting bars 53 and pulling them out from the limiting holes 13 at the top of the treatment box body 1. Subsequently, the staff pulls the handle 42, thereby driving the sealing plate 41 together with the connecting rod 7 to be pulled, so that the push plate 6 in contact connection with the inner wall of the treatment box body 1 moves inside the treatment box body 1 and pushes the sundries collected inside the treatment box body 1 to the opening on the front of the treatment box body 1, so as to clean the sundries inside the treatment box body 1.

[0132] When the work of pushing the sundries out of the treatment box body 1 is completed, the staff closes the handle 42 and the treatment box body 1, so that the push plate 6 drives the push plate 6 to contact and fit with the inner wall of the treatment box body 1 again through the connecting rod 7; then the staff locks and connects the sealing component 4 to the treatment box body 1 through the limiting mechanism 5. The operator pulls up the connecting bar 52 upward and closes the sealing plate 41 towards the opening of the treatment box body 1. When the through hole of the limiting connecting plate on the limiting connecting plate 51 coincides with the limiting hole 13, the operator releases the connecting bar 52. Under the elastic action of the spring 54, the connecting bar 52 drives the connecting bar 52 to retract downward, and then drives the lower end of the limiting bar 53 to be clamped in the limiting hole 13 to complete the sealing of the treatment box body 1 and the sealing plate 41. Finally, the staff can open the valve 22 provided on the connecting pipe 2a, thereby realizing the opening of the water inlet of the treatment box body 1, so that the water can flow smoothly. At this time, the smooth progress of the drainage work can be ensured. The above operations are cycled in sequence until all the drainage work of the return water of the curtain grouting holes is completed.

[0133] During the entire implementation operation process described above, the valve 22 is a manual valve or an automatic electric valve, which is used to close the water flow of the support water inlet pipe 8 and stop the water supply work for the treatment box body 1.

[0134] Finally, as time goes by, when the present invention is no longer in use, the operator only needs to clean and repair each component of the present invention, and then transport it to the designated tool storage warehouse for storage through manual or corresponding equipment for storage for the next cycle of turnover use.

[0135] During the entire above-mentioned implementation process, since the present invention is designed with the connecting pipe 2a and the valve 22 cooperating with each other, the water inlet of the processing box body can be opened or sealed, so that the drainage operation can be interrupted during the process of the staff cleaning the inside of the processing box body, preventing debris in the water from accumulating in front of the pushing plate, which is conducive to the cleaning work of the staff.

[0136] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
