Description

Technical Field

[0001] This utility model relates to the field of diaphragm wall cleaning technology, and in particular to a diaphragm wall brushing device and equipment. Background Technology

[0002] A diaphragm wall is a reinforced concrete wall constructed in sections within the strata. It is mainly used for deep foundation pit support, seepage prevention and retaining, or as part of a permanent underground structure. After trenching, the sidewalls of the trench need to be cleaned to remove the attached mud. After cleaning, the mud blocks removed need to be removed from the trench to reduce the height of the mud accumulation at the bottom of the trench. In the existing technology, a crawler crane is usually used to lift a wire brush to clean the wall. After cleaning, the mud in the trench is then pumped out or excavated. This process generally takes a long time and has low cleaning efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the problem of low hole cleaning efficiency of existing equipment in the background art, and to provide a wall brushing device and equipment for diaphragm walls.

[0015] Preferably, the wire brush includes at least two wire ropes, which are fixed to the outer wall of the mounting plate, and the diameter of the wire ropes is 10mm to 14mm.

[0016] Preferably, the outer wall of the cylinder is provided with ribs, the ribs are spirally surrounding the cylinder, the ribs are integrally formed with the cylinder, and the opening is located between two ribs distributed along the axial direction of the cylinder.

[0039] Example

[0040] In the first aspect, such as Figures 1 to 3 As shown, this application provides a wall cleaning device for diaphragm walls, including a cylinder 1 and a cleaning assembly disposed on the side wall of the cylinder 1.

[0041] The cylinder 1 can be a cylindrical component made of steel. The hole cleaning assembly is set on the outer wall of the cylinder 1. The hole cleaning assembly can be moved by inserting the cylinder 1 into the slot of the diaphragm wall and moving the cylinder 1 to carry out the hole cleaning operation. In the example, the cylinder 1 is 1.5m long and 0.7m in diameter.

[0042] In some embodiments, the cylinder 1 has an inner cavity, and at least one opening 15 is provided on the side wall of the cylinder 1, the opening 15 being connected to the inner cavity. The cylinder 1 has a first end 11 and a second end 12 along its axial direction, and the first end 11 is provided with an opening and closing device, which is capable of opening and closing the cylinder opening of the first end 11.

[0043] In the preferred method of use, the cylinder 1 extends vertically into the slot of the diaphragm wall and moves up and down. The first end 11 is the lower end of the cylinder 1, and the second end 12 is the upper end of the cylinder 1. The opening 15 is connected to the inner cavity, and the cylinder opening at the lower end of the cylinder 1 can be switched between open and closed states. The diameter of the opening 15 is large enough for mud blocks to pass through. During the hole cleaning operation, keeping the cylinder opening at the lower end of the cylinder 1 closed allows the mud blocks that have been cleaned to flow into the inner cavity through the opening 15 and be stored there. When a large amount of mud blocks are stored, the cylinder 1 can be lifted from the slot of the diaphragm wall and moved to the adjacent dumping area. Then, the cylinder opening at the first end 11 is switched to the open state, allowing the mud blocks in the inner cavity to fall into the dumping area. The above steps can then be repeated to continue cleaning the hole.

[0044] It is understandable that during the hole cleaning operation, the vertical movement of the cylinder 1 and the hole cleaning assembly will agitate the water in the diaphragm wall hole groove, causing the fallen mud blocks and other blocks to be in a state of agitation or floating. By setting the opening 15 on the side wall of the cylinder 1, some of the cleaned blocks can flow into and accumulate in the inner cavity of the cylinder 1, and be carried away from the inner cavity as the cylinder 1 is lifted. This can reduce the height of the mud blocks accumulating at the bottom of the diaphragm wall hole groove, which is conducive to reducing the subsequent cleaning time. Moreover, mud blocks in a state of agitation or floating are easier to clean than accumulated mud blocks, which is conducive to improving the hole cleaning efficiency.

[0045] In some embodiments, the hole cleaning assembly includes chisel teeth 3 and wire brush 4. The chisel teeth 3 are hard tooth-shaped structures, for example, their material can be wear-resistant alloy steel or nylon steel wire composite, which can be used to break hard rocks and scrape firmly attached mud blocks; the wire brush 4 can be used to scrape off loose mud skin. By simultaneously setting chisel teeth 3 and wire brush 4, most cleaning needs can be met, and frequent device replacement is not required, which helps to improve cleaning efficiency.

[0046] In some embodiments, a mounting plate 2 spaced apart from the side wall of the cylinder 1 is further provided on the cylinder 1, and the chisel teeth 3 and / or wire brush 4 are fixed on the mounting plate 2. The mounting plate 2 is spaced apart from the side wall of the cylinder 1, and a channel for mud to flow through can be left between them, thereby reducing the resistance to the up and down movement of the cylinder 1. The mounting plate 2 also allows the chisel teeth 3 and wire brush 4 to protrude to a position at a certain distance from the side wall of the cylinder 1, thereby reducing the probability of the cylinder 1 colliding with the side wall of the ground beam wall during the cleaning process.

[0047] Preferably, mounting plates 2 are provided on both radially opposite sides of the cylinder 1, and one mounting plate 2 is provided with chisel teeth 3, which protrude from the outer wall of the mounting plate 2; the other mounting plate 2 is provided with wire brush 4, which protrudes from the outer wall of the mounting plate 2.

[0048] Preferably, the mounting plate 2 is connected to the cylinder 1 via a connecting assembly. The connecting assembly can be a connecting plate, such as a steel plate, disposed between the mounting plate 2 and the cylinder 1. The number of connecting plates can be one or more.

[0049] Furthermore, there is a channel 21 between the mounting plate 2 and the outer wall of the cylinder 1. The channel 21 allows water to flow through, which can reduce the resistance of the wall-mounted brush device extending downward into the water and increase the downward impact strength.

[0050] The wall-mounted brushing device described in this embodiment has an opening 15 on the side wall of the cylinder 1 and an opening and closing device at the lower end of the cylinder 1. During cleaning, the opening and closing device can be closed, allowing mud lumps or other blocks that are turned up or floated during the cleaning process to flow into and be stored in the inner cavity through the opening 15. They are then carried out of the groove as the cylinder 1 is lifted. This reduces the height of mud lumps accumulating at the bottom of the groove, reducing subsequent cleaning time. Moreover, mud lumps that are turned up or floated are easier to clean than accumulated mud lumps, which helps improve the cleaning efficiency. By simultaneously setting the wall-mounted teeth 3 and the wire brush 4, most cleaning needs can be met, and frequent device replacement is not required, which helps improve cleaning efficiency.

[0051] In some embodiments, when the opening and closing device closes the opening of the first end 11, the first end 11 has a drainage channel. The drainage channel allows water to flow through, but can block lumps such as mud with a certain volume. When the cylinder 1 moves up and down in the diaphragm wall slot through the drainage channel, the water level in its inner cavity can change dynamically, so that external water can continuously flow into the inner cavity from the opening 15. For example, when the cylinder 1 is lifted, the water in the inner cavity flows out from the drainage channel, but solids such as mud lumps remain in the inner cavity, and the water level in the inner cavity decreases. Then, when the cylinder 1 falls, because the water level in the inner cavity is low, external water will flow into the inner cavity from the opening 15 under the action of gravity, and bring in new mud lumps, etc. This cycle can make more mud lumps in the external water flow into the inner cavity, thereby reducing the height of mud lumps accumulating at the bottom of the diaphragm wall slot.

[0052] Preferably, the drainage channel can be formed by a drainage hole provided on the side wall of the cylinder 1, or by a gap left on the opening and closing device. The drainage channel can allow small-diameter mud and sand to pass through, such as mud and sand particles with a diameter ≤2mm. The specific design can be based on the actual working conditions.

[0053] In some embodiments, the opening 15 is located on the side of the mounting plate 2 away from the first end 11, that is, above the mounting plate 2. It can be understood that since the structure such as the cylinder 1 has a large self-weight, the impact force when the cylinder 1 moves downward is greater than the impact force when it is lifted. The mud blocks and the like mainly fall off due to the scraping when the cylinder 1 moves downward. By setting the opening 15 above the mounting plate 2, the fallen mud blocks can approach the opening 15 and flow into the cylinder 1, so that more mud blocks can be collected by the cylinder 1.

[0054] In some embodiments, the size of the opening 15 in the axial direction of the cylinder 1 is larger than the size of the opening 15 in the circumferential direction of the cylinder 1, thereby increasing the vertical size of the opening 15 so that more of the layered mud blocks in the external water can flow into the inner cavity from the opening 15.

[0055] In some embodiments, the distance between the mounting plate 2 and the first end 11 is less than the distance between the mounting plate 2 and the second end 12.

[0056] In some embodiments, the cylinder 1 has a first side and a second side distributed radially. The mounting plate 2 on the first side is provided with chisel teeth 3, and the mounting plate 2 on the second side is provided with wire brush 4. That is, the chisel teeth 3 and the wire brush 4 are respectively arranged on both sides of the cylinder 1, and different cleaning tools can be switched by rotating the cylinder 1.

[0057] In some embodiments, further, such as Figure 3As shown, the first side is provided with two flush mounting plates 2, and a straight gap 22 is provided between the two mounting plates 2. The gap 22 is parallel to the axis of the cylinder 1. The gap 22 allows the protruding structure of the diaphragm wall sidewall to pass through, such as the protruding steel plate of the cross steel plate joint, to clean the sidewalls on both sides of the protruding structure. By setting the gap 22, the applicability of the chisel teeth 3 can be improved, and the situation where it is impossible to chisel out due to the existence of protruding structures can be reduced, thereby reducing costs and improving efficiency.

[0058] In some embodiments, the chisel teeth 3 are inclined relative to the outer wall of the mounting plate 2, and the distance from the end of the chisel teeth 3 near the first end 11 to the axis of the cylinder 1 is greater than the distance from the end of the chisel teeth 3 away from the first end 11 to the axis of the cylinder 1, so that the downward moving chisel teeth 3 can effectively hang down the mud blocks attached to the side wall of the diaphragm wall. In the first example, the chisel teeth 3 can be 8cm wide inclined ribs, which can be steel plates, and the spacing between adjacent chisel teeth 3 can be 5cm. In the second example, the chisel teeth 3 can be 12cm wide inclined ribs, and the spacing between adjacent chisel teeth 3 can be 7cm.

[0059] In some embodiments, the second end 12 of the cylinder 1 is provided with a connecting part for connecting with the drill rod of the rotary drilling rig.

[0060] In some embodiments, the connecting part further includes a connecting sleeve 5, the side wall of the connecting sleeve 5 is provided with a fixing hole 51, the fixing hole 51 is used for fixing the end of the rotary drilling rig; the connecting sleeve 5 is a cylindrical structure with an opening at its upper end and a cavity inside, the drill rod of the rotary drilling rig can extend into the cavity from the opening, and a threaded hole can be provided on the drill rod, so that the fixing hole 51 on the side wall of the connecting sleeve 5 can be aligned with the threaded hole and fixed with a bolt, the bolt passes through the fixing hole 51 and is embedded in the threaded hole.

[0061] Preferably, the side wall of the connecting sleeve 5 is provided with a reinforcing plate 6, the reinforcing plate 6 connects the side wall of the connecting sleeve 5 and the top surface of the cylinder 1, and at least three reinforcing plates 6 are arranged circumferentially along the connecting sleeve 5, the reinforcing plate 6 can enhance the strength.

[0062] In some embodiments, the opening and closing device includes a fixed plate and a rotating plate. The fixed plate covers part of the opening of the first end 11, and the rotating plate can rotate about the axis of the cylinder 1 to cover or open the remaining opening of the first end 11. That is, when the rotating plate rotates to coincide with the fixed plate, the opening of the first end 11 is partially open, and when the rotating plate rotates to the position of the remaining opening, the opening of the first end 11 is closed.

[0063] It should be noted that the remaining opening of the rotating plate at the first closed end 11 in this embodiment is not completely sealed, but allows water and small-diameter particles to pass through, as long as it can block large-diameter mud lumps.

[0064] In some embodiments, the wire brush 4 includes at least two wire ropes fixed to the outer wall of the mounting plate 2, and the diameter of the wire ropes is 10mm to 14mm; in the example, the length of the wire rope is 50cm and the diameter is 12mm.

[0065] In some embodiments, the outer wall of the cylinder 1 is provided with ribs 14, which spirally and uniformly surround the outer wall of the cylinder 1 from top to bottom. The ribs 14 can be die-cast together with the cylinder 1 to enhance the structural strength of the cylinder 1. The opening 15 is preferably located between two ribs 14 distributed along the axial direction of the cylinder 1, because the opening 15 will reduce the structural strength of the cylinder 1 to a certain extent. Setting the opening 15 between two ribs 14 can reduce the strength damage of the cylinder 1.

[0066] In a second aspect, this application provides a wall-mounted brushing device, including a rotary drilling rig and a wall-mounted brushing device as described above. The wall-mounted brushing device is connected to the drill rod of the rotary drilling rig, and the rotary drilling rig can drive the wall-mounted brushing device to move vertically.

[0067] Preferably, the drill rod of the rotary drilling rig is driven by a hydraulic or electric motor, and the extension and retraction of the drill rod can drive the cylinder 1 to move vertically. The power of the rotary drilling rig is selected according to the wall resistance, and is usually 5kW to 15kW.

[0068] Preferably, the rotary drilling rig has a lateral guide wheel or an ultrasonic sensor to monitor the tilt angle of the drill rod. By adjusting the angle or position of the drill rod, the wall-brushing angle and pressure can be adjusted.

[0069] The diaphragm wall brushing device described in this embodiment is simple in design, low in manufacturing cost, and low in maintenance and replacement cost. By connecting to the drill rod of a rotary drilling rig, the device moves up and down using the power of the rig to clean up attached mud and sludge. It is applicable to different types of diaphragm wall joints and diaphragm walls of various depths, achieving efficient and rapid cleaning of mud, sand, and gravel in underground spaces. By connecting to the drill rod of the rotary drilling rig, it performs forced brushing from top to bottom, which has a significant effect on removing the surrounding concrete and clay attached to the I-beam joint. At the same time, the device uses a rotary drilling rig for excavating diaphragm wall trenches, saving the cost of using a crane for brushing.

[0070] In a third aspect, this application provides a method for cleaning holes in a diaphragm wall, using the diaphragm wall brushing device described above, comprising the following steps:

[0071] S1. Tank Section Inspection: Ultrasonic wall gauge is used to check the mud cake thickness and sediment accumulation at the joint location;

[0072] S2. Equipment debugging: Lock the diaphragm wall brushing device to the rotary drilling rig to ensure that the device is not loose;

[0073] S3. First wall brushing (coarse brushing): This is carried out immediately after the trench is formed. A wire brush 4 is used to move up and down in a reciprocating motion (speed 2~3m / min) to remove most of the loose mud skin and carry out the thicker mud slurry through the cylinder 1.

[0074] S4. Second wall brushing (fine brushing): Repeat the operation before lowering the reinforcing cage, using wall chisel teeth 3 to thoroughly clean away any residue; mud removal standard: exposed concrete area at joints ≥90%

[0075] S5. Check the thickness of sediment: After brushing the wall, drop a measuring rope and a weight to check the thickness of sediment (≤100mm).

[0076] Preferably, when brushing the wall, the reverse circulation pump should be started to remove debris in time to avoid secondary deposition of the brushed mud or concrete; the brushing speed should be reduced near the H-beam or joint pipe to prevent structural damage.

[0077] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
