Description

Technical Field

[0001] The invention relates to the field of ground-connected wall construction, and in particular to a wall-brushing device with a ground-connected wall obstacle-clearing function and a construction method. Background Art

[0002] The underground continuous wall construction, also known as underground continuous wall construction, is an important foundation construction technology in construction projects. This technology is mainly used to reinforce the land and prevent soil erosion. As part of the underground structure, it undertakes multiple functions such as water interception, anti-seepage, load bearing, and water retaining.

[0003] In the prior art, the construction process of the ground-connected wall usually requires the use of special trenching equipment, such as a trenching machine or a rotary drilling rig, to dig or drill a trench with a certain width and depth along the predetermined position, and then use mud wall protection to form the trench and set a steel cage with a certain rigidity in the trench; then use a conduit to pour underwater concrete to build a unit trench, and then proceed section by section. During the construction process, in order to ensure that the new and old concrete are tightly connected, it is often necessary to brush the trench wall with a brushing steel brush.

[0004] With regard to the above-mentioned prior art, the trench wall conditions of the excavated trench are complicated. When facing obstacles with relatively large rigidity, it is usually necessary to remove the wall brush and replace it with a scraper to clean the obstacles with relatively large rigidity. The operation is complicated and the work efficiency of cleaning the obstacles in the trench is low. Summary of the invention

[0007] By adopting the above technical scheme, when the groove wall needs to be brushed, the wall brush body is first installed on the drill rod of the rotary drilling rig, and then the drill rod moves in the vertical direction so that the ultrasonic probe can detect the inner wall of the groove while moving along with the wall brush body and the drill rod in the vertical direction, thereby realizing a preliminary judgment on the condition of the inner wall of the groove. When facing an obstacle with smaller rigidity in the groove, the obstacle can be cleaned by moving the wall brush steel brush in the vertical direction. When facing an obstacle with larger rigidity in the groove, the drill rod is rotated so that the wall brush scraper rotates with the wall brush body and the drill rod to the position of the obstacle with larger rigidity, and then the obstacle can be cleaned by moving the wall brush scraper in the vertical direction. During the cleaning process of obstacles with different rigidities, there is no need to take out the wall brush body for replacement. The rotary drilling rig can be driven to drive its own drill rod to rotate and move in the vertical direction.

The self-locking effect between the brush wall worm and the brush wall worm wheel is conducive to fully ensuring the stability of the position of the bidirectional lead screw after rotation, thereby ensuring the stability of the two brush wall sliders after movement.

The second vertical section 503 and the second vertical section 503 are respectively connected to the two ends of the horizontal section 502. The first vertical section 501 extends to the bottom of the first connecting ring 2. When the connecting rod 4 slides into the connecting groove 5 through the first vertical section 501 and falls into the second vertical section 503 after rotation, the connection between the first connecting ring and the second connecting ring 3 is realized, that is, the connection between the wall brush body 1 and the drill pipe of the rotary drilling rig is realized.

When the connecting rod 4 is located in the second vertical section 503, the pressing ring 6 presses against the top of the second connecting ring 3 under the elastic force of the pressing spring 7, so as to limit the position of each connecting rod 4 and the second connecting ring 3. A fixing hole 8 is provided on the outer peripheral surface of the second connecting ring 3, and a fixing bolt 9 is threadedly matched on the outer peripheral surface of the first connecting ring 2. When the connecting rod 4 is located in the second vertical section 503, the fixing bolt 9 is opposite to the fixing hole 8. At this time, when the fixing bolt 9 is screwed so that the fixing bolt 9 penetrates into the fixing hole 8, the stable limit of the position of the pressing ring 6 is achieved.

[0039] Reference Figure 2 In the embodiment of the present application, the cross section of the wall brush body 1 is rectangular, and the wall brush body 1 has four wall brushing surfaces 101 distributed circumferentially around its own axis.

Specifically, the first wall brushing component includes a wall brushing mounting plate 10 and a wall brushing steel brush 11. In the embodiment of the present application, there are three wall brushing mounting plates 10 distributed in the vertical direction, and three groups of wall brushing steel brushes 11 are arranged corresponding to the wall brushing mounting plates 10. The wall brushing steel brushes 11 of each group are respectively installed on the side of each wall brushing mounting plate 10 away from the wall brush body 1. When the drill rod of the rotary drilling rig moves in the vertical direction, each wall brushing steel brush 11 can clean obstacles with less rigidity.

[0040] Reference Figure 2 and Figure 4 The wall brush body 1 is provided with a wall brush motion assembly to drive the wall brush mounting plate 10 to move toward or away from the wall brush body 1, so that the wall brush steel brush 11 can adapt to different internal conditions of the groove. Specifically, the wall brush motion assembly includes a wall brush slider 12, a wall brush connecting rod 13, a wall brush limiting rod 14 and a wall brush driving member, wherein the wall brush slider 12, the wall brush connecting rod 13 and the wall brush limiting rod 14 are vertically arranged in three groups corresponding to the wall brush mounting plate 10, and each group of wall brush sliders 12 is provided with two, and the wall brush body 1 is provided with three wall brushing grooves 15 distributed in the vertical direction, and each group of two wall brushing sliders 12 are slidably matched in the wall brushing groove 15 of the wall brush body 1 in the horizontal direction, and the two wall brushing sliders 12 can move along the wall brushing groove 15 in the direction of approaching or moving away from each other.

[0041] Continue to refer to Figure 2 and Figure 4Each set of wall brushing connecting rods 13 is provided with two, one end of the two wall brushing connecting rods 13 is rotatably mounted on the two wall brushing sliding blocks 12 respectively, and the other end is rotatably mounted on the side of the wall brushing mounting plate 10 close to the wall brushing device body 1. The wall brush limit rod 14 is a telescopic rod. In the embodiment of the present application, each group of wall brush limit rods 14 is provided with two, and the wall brush limit rod 14 includes a first rod body 141 and a second rod body 142. A limiting slide groove 16 extending along its own length direction is opened on the side of the wall brush mounting plate 10 close to the wall brush device body 1. One end of the first rod body 141 of the two wall brush limit rods 14 is slidably fitted in the limiting slide groove 16 of the wall brush mounting plate 10, and one end of the second rod body 142 of the two wall brush limit rods 14 is respectively fixedly installed on the two wall brush sliders 12. The first rod body 141 of the two wall brush limit rods 14 is respectively penetrated by the two second rod bodies 142 and slidably fitted with the two second rod bodies 142, so that when the two wall brush sliders 12 move along the wall brush slide groove 15 in the direction of approaching or moving away from each other, the wall brush mounting plate 10 moves in the direction of approaching or moving away from the wall brush device body 1 under the drive of the wall brush connecting rod 13 and the limiting action of the wall brush limit rod 14.

[0042] Reference Figure 4 The wall brush driving part includes a wall brush motor 17, a wall brush driving rod 18, a bidirectional screw rod 19, a wall brush worm wheel 20 and a wall brush worm 21, wherein three bidirectional screw rods 19 are distributed along the vertical direction corresponding to the wall brush slide groove 15, and each bidirectional screw rod 19 is rotatably installed on the wall brush device body 1, and the two ends of each bidirectional screw rod 19 with opposite thread rotation directions are respectively penetrated through the two wall brush sliders 12 of each group and matched with the thread of the wall brush slider 12, so that when the bidirectional screw rod 19 rotates, the two wall brush sliders 12 of each group move towards or away from each other under the limiting action of the wall brush slide groove 15.

[0043] Reference Figure 2 and Figure 4 The wall brush driving rod 18 is vertically rotated and installed in the wall brush body 1, the wall brush motor 17 is installed in the wall brush body 1, and one end of the wall brush driving rod 18 is fixedly installed at the output end of the wall brush motor 17, so that the wall brush motor 17 drives the wall brush driving rod 18 to rotate. There are three sets of wall brush worm wheels 20 and wall brush worms 21 corresponding to the bidirectional screws 19, and each wall brush worm wheel 20 is coaxially fixedly connected to each bidirectional screw 19, and each wall brush worm 21 is coaxially fixedly connected to the wall brush driving rod 18, and each wall brush worm 21 is meshed with each wall brush worm wheel 20, so that when the wall brush driving rod 18 rotates, each bidirectional screw 19 rotates synchronously due to the meshing of the wall brush worm 21 and the wall brush worm wheel 20. Then, the rotation of the wall brush driving rod 18 driven by a single wall brush motor 17 facilitates the final synchronous movement of each wall brush steel brush 11 toward or away from the wall brush body 1, which is fast and stable.

[0044] Reference Figure 1 and Figure 2The second wall brushing assembly includes a wall brushing scraper 22 disposed on the side of the wall brushing device body 1 away from the first wall brushing assembly. Specifically, the wall brushing scraper 22 includes a scraper mounting seat 221 and a scraper portion 222, wherein the scraper mounting seat 221 is fixedly mounted on the wall brushing device body 1. In the embodiment of the present application, there is an angle of 30 degrees between the scraper mounting seat 221 and the wall brushing device body 1. The scraper portion 222 is integrally fixedly connected with two fixed ear plates 23. The scraper portion 222 is fixedly mounted on the end of the scraper mounting seat 221 away from the wall brushing device body 1 through two bolts that penetrate the fixed ear plates 23 and threadedly cooperate with the scraper mounting seat 221. The detection mechanism includes an ultrasonic probe 24 disposed on the wall brushing device body 1. In the embodiment of the present application, the ultrasonic probe is disposed on the side of the wall brushing device body 1 adjacent to the second wall brushing assembly. When the drill rod moves in the vertical direction in the groove, the ultrasonic probe 24 realizes the detection and processing of the inner wall of the groove.

[0045] The implementation principle of the wall brushing device with the function of clearing obstacles of the ground-connected wall in the embodiment of the present application is as follows: when the wall of the groove needs to be brushed, the wall brush body 1 is first installed on the drill rod of the rotary drilling rig through the cooperation of the first connecting ring 2 and the second connecting ring 3, and then the drill rod moves in the vertical direction so that the ultrasonic probe 24 can detect the inner wall of the groove while the wall brush body 1 and the drill rod move in the vertical direction, thereby realizing a preliminary judgment on the condition of the inner wall of the groove. When facing an obstacle with less rigidity in the groove, the wall brush steel brush 11 is moved in the vertical direction to The obstacles can be cleaned up. When facing an obstacle with greater rigidity in the groove, the drill rod is rotated so that the wall scraper 22 rotates together with the wall scraper body 1 and the drill rod to the position of the obstacle with greater rigidity. Then, the wall scraper 22 can be cleaned up by moving in the vertical direction. During the cleaning process of obstacles with different rigidities, there is no need to take out the wall scraper body 1 for replacement. The rotary drilling rig can be driven to drive its own drill rod to rotate and move in the vertical direction. The operation is simple and beneficial to improving the work efficiency when cleaning obstacles in the groove.

[0046] The embodiment of the present application also discloses a construction method of a wall-brushing device based on the ground-connected wall obstacle removal function. The construction method of the wall-brushing device based on the ground-connected wall obstacle removal function specifically includes the following steps: S1. After the groove is opened, the wall brush body is installed on the drill rod of the rotary drilling rig. Specifically, the connecting rod of the second connecting ring is installed to the connecting groove of the first connecting ring. When the connecting rod is located in the second vertical section of the connecting groove, the first connecting ring and the second connecting ring are firmly fixed by passing the fixing bolts through the fixing holes.

[0047] S2, extending the drill rod of the rotary drilling rig into the opened trench, and detecting the inner wall of the trench by using an ultrasonic probe.

[0048] S3, the obstacles with smaller rigidity are cleaned by the vertical movement of the brush. Specifically, the rotary drilling rig drives the drill rod to move in the vertical direction so that the brush can clean the obstacles with smaller rigidity in the groove.

[0049] S4, clearing relatively rigid obstacles by vertically moving the wall scraper. Specifically, when relatively rigid obstacles are difficult to be cleared by the wall brush, firstly, the rotary drilling rig drives the drill rod to rotate so that the wall brush is moved to face the relatively rigid obstacles, and then the rotary drilling rig drives the drill rod to move vertically so that the wall scraper can clear the relatively rigid obstacles in the groove.

[0050] S5, after the obstacles on the inner wall of the groove are cleared, the wall scrubber body is taken out of the groove by moving the drill rod in the vertical direction, and the cleaning of the inner wall of the groove is completed.

[0051] The implementation principle of the construction method of a wall brushing equipment based on the ground-connected wall obstacle clearing function in the embodiment of the present application is as follows: when it is necessary to clean obstacles of different rigidity in the groove, there is no need to take out the wall brush body for replacement. By driving the rotary drilling rig to drive its own drill rod to rotate and move in the vertical direction, the wall brushing steel brush and the wall brushing scraper can clean the obstacles with smaller and larger rigidity in turn. The operation is simple and conducive to improving the work efficiency when cleaning obstacles in the groove.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
