Description

Technical Field

[0001] This utility model relates to the field of anti-seepage wall construction technology, and in particular to an arc-shaped wall brush for attaching to a trenching machine in anti-seepage wall construction using a lock-joint pipe. Background Technology

[0002] In construction engineering, when using a seepage barrier as a water-stop curtain, a trenching machine is required in conjunction with interlocking pipes for construction. The interlocking pipes form a semi-circular joint at the end of the trench section, facilitating the connection between adjacent trench sections. During construction, a unit trench section is first excavated, then the interlocking pipe is hoisted into the end of the unit trench section. After the interlocking pipe is in place, a reinforcing cage is hoisted into the trench section and concrete is poured. After the concrete has initially set, the interlocking pipe is hoisted out. Once the concrete has completely solidified, the trench section is formed, and the next trench section is constructed one by one. Before constructing the next trench section, the concrete sidewalls of the previously formed trench section must be brushed to ensure the joint between adjacent trench sections is clean, reducing the risk of seepage after the foundation pit is excavated. The more thorough and cleaner the brushing, the lower the risk of leakage. Because the interlocking pipe is circular, the resulting joint surface is semi-circular, making it difficult to clean with conventional brushing tools, easily leading to incomplete cleaning and affecting the construction quality.

[0003] Therefore, how to create a new type of arc-shaped wall brush for attaching to trenching machines in the construction of anti-seepage walls using lock-joint pipes is one of the important research and development topics at present. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an arc-shaped wall brush for attaching to the trenching machine in the construction of a seepage barrier wall using a lock-joint pipe. This allows the brush to completely fit the semi-circular joint surface formed after the lock-joint pipe is pulled out. The brush has comprehensive functions of brushing, scraping mud, and roughening, improving the brushing effect, avoiding sand and mud inclusion between adjacent trench sections, reducing the risk of water seepage and leakage at the joints, and improving the overall construction quality of the seepage barrier wall, thereby overcoming the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model provides an arc-shaped wall brush for attaching to a trenching machine to form an anti-seepage wall during the construction of a lock-joint pipe, comprising a vertical base plate, a steel brush layer, and a mud scraping and roughening layer;

[0006] The vertical substrate is a vertically arranged rectangular steel plate. The front and side surfaces are horizontally welded with three layers of steel brush and mud scraping and texturing layer at equal intervals. The steel brush layer is located in the upper and middle layers, and the mud scraping and texturing layer is located in the lower layer.

[0007] The steel brush layer includes an upper fixing plate, a lower fixing plate, and steel wires. Both the upper and lower fixing plates are arc-shaped, with a gap between them. Several steel wires are evenly installed in the gap around the perimeter, with the ends of the steel wires extending out of the edges of the upper and lower fixing plates.

[0008] The mud-scraping and texturing layer includes a mud-scraping plate and a texturing plate. Both the mud-scraping plate and the texturing plate are arc-shaped and are stacked one on top of the other. The edges of the texturing plate are continuously provided with sharp, protruding spikes.

[0009] As an improvement of this utility model, a vertical rib is welded to the middle of the vertical substrate. The rib is welded and fixed to the steel brush layer and the mud scraping and texturing layer respectively to increase the overall strength.

[0010] Furthermore, the steel wire is connected to the upper fixing plate and the lower fixing plate by bolts.

[0011] Furthermore, several brush gears are evenly arranged on the left and right sides of the vertical substrate along the vertical direction.

[0012] Furthermore, lifting rings are welded and fixed to the top of the vertical substrate and the top of the uppermost steel brush layer.

[0013] Furthermore, the vertical base has a connecting seat and a connecting groove welded to its back surface for connection with the troughing machine bucket.

[0014] With this design, the present invention has at least the following advantages:

[0015] 1. Two layers of steel brushes and one layer of mud scraping and roughening are set from top to bottom, which has a multi-functional comprehensive wall brushing effect of roughening, mud scraping and wall brushing. Both the steel brush layer and the mud scraping and roughening layer can perfectly fit the semi-circular joint surface formed after the lock pipe is pulled out, which improves the quality and efficiency of wall brushing, avoids the phenomenon of sand and mud inclusion between adjacent trench sections, and avoids affecting the overall effect of the underground continuous wall. In the later stage of foundation pit excavation, the risk of water seepage and leakage at the joints is reduced.

[0016] 2. The brushing gears set on both sides of the vertical base plate can ensure that the brush is stably attached to the semi-circular joint surface, making the up-and-down movement smoother and more stable. At the same time, it can also clean the blind areas on both sides, further improving the brushing effect.

[0017] 3. The steel wire is bolted to the upper and lower fixing plates for easy maintenance and replacement;

[0018] 4. It has a simple structure, is easy to use, and is suitable for widespread application. Attached Figure Description
