Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-seepage component for diaphragm walls. Background Art

[0002] A diaphragm wall is a structure commonly used in underground engineering, which is a wall structure used to prevent groundwater seepage, provide support and separate underground spaces. It is usually composed of concrete, steel bars and other materials and plays an important role in underground engineering.

[0003] The pressure of groundwater will exert additional forces on the diaphragm wall, thus increasing the seepage risk of the wall. Especially in areas with high groundwater levels or areas with large fluctuations in groundwater levels, the pressure of groundwater will increase the possibility of leakage. For this reason, an anti-seepage component for diaphragm walls is proposed to solve the above problems. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides an anti-seepage component for diaphragm walls, aiming to improve the problem that the pressure of groundwater in the prior art will exert additional forces on the diaphragm wall, thus solving the seepage risk of the wall.

[0027] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0028] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: an anti-seepage component for a diaphragm wall, including a construction trench 1. Inside the construction trench 1, there is a wall body 2. The height of the wall body 2 exceeds the height of the construction trench 1. By the height of the wall body 2 exceeding the height of the construction trench 1, it ensures that the depth of the wall body 2 underground is sufficient, providing better support and anti-seepage effects, and preventing road surface water from entering the construction trench 1. Between the wall bodies 2, there is a steel reinforcement cage 3. The steel reinforcement cage 3 is used to enhance the structural strength between the wall bodies 2. The steel reinforcement cage 3 includes four groups of transverse steel bars 31 and longitudinal steel bars 32. Among them, there are multiple groups of longitudinal steel bars 32 arranged horizontally, and both ends of the longitudinal steel bars 32 are fixedly connected to support plates 33. The support plates 33 are fixedly connected to the side walls of the wall body 2. The transverse steel bars 31, longitudinal steel bars 32, and support plates 33 help to maintain the stability of the steel bars and the strength of the overall structure, preventing the deformation and damage of the wall body 2.

[0029] Refer to Figure 3 - Figure 4 , inside the wall body 2, there is an anti-leakage component 4. The anti-leakage component 4 is located inside the wall body 2 and is mainly used to prevent groundwater from leaking into the soil around the wall body 2. The anti-leakage component 4 includes an installation groove 41. The installation groove 41 is opened inside the wall body 2. The installation groove 41 is used to install other components and provide a space for accommodating seepage water. The inner bottom surface of the installation groove 41 is fixedly connected to a collection groove 42. The bottom surfaces of the collection groove 42 and the installation groove 41 are both inclined. The collection groove 42 is located inside the installation groove 41, collecting seepage water and guiding it to a drain pipe 44. The inclined bottom surface is for effectively collecting and discharging the leaked water. The end of the collection groove 42 is fixedly connected to a sealing plate 43. The sealing plate 43 is located at the end of the collection groove 42, preventing seepage water from penetrating through this part into the soil around the wall body 2. The side wall of the sealing plate 43 is fixedly connected to a drain pipe 44. The drain pipe 44 is used to discharge the collected water from the area around the wall body 2, preventing water accumulation from causing leakage of the wall body 2. The side wall of the wall body 2 is fixedly connected to a waterproof cloth 45. The waterproof cloth 45 further enhances the anti-seepage effect, preventing water from penetrating into the inside of the wall body 2 from the side.

[0030] Refer to Figure 3, a plurality of support blocks 46 distributed in an array are fixedly connected between the inner walls of the installation groove 41. The support blocks 46 are used to enhance the structural stability of the installation groove 41. An upper cover plate 47 is inserted into the installation groove 41. The upper cover plate 47 is used to cover the installation groove 41 and fix the water absorption plate 48. A plurality of water absorption plates 48 distributed in an array are fixedly connected to the bottom surface of the upper cover plate 47. The water absorption plates 48 are inserted into the installation groove 41. The water absorption plates 48 are used to absorb the moisture around the wall 2 and reduce the possibility of leakage.

[0031] Working principle: During the construction of the diaphragm wall, the construction groove 1 is first excavated, and then the wall 2 is constructed and fixed inside the construction groove 1. Since the height of the wall 2 exceeds that of the construction groove 1, the bottom of the wall 2 can penetrate deeper into the soil, providing better support and anti-seepage effects. At the same time, it effectively prevents the road surface water from seeping into the ground through the construction groove 1.

[0032] The setting of the steel reinforcement cage 3 further strengthens the structural strength of the wall 2. The transverse steel bars 31 and the longitudinal steel bars 32 are intertwined to form a strong framework, and the support plate 33 ensures the stable connection between the steel reinforcement cage 3 and the wall 2, making the wall 2 more durable and able to withstand various external pressures and stresses.

[0033] The introduction of the anti-leakage component 4 further improves the anti-seepage performance of the diaphragm wall. The installation groove 41 provides an installation space for other components and also forms an area for accommodating seepage water. The inclined design of the collection groove 42 enables the seepage water to flow smoothly to the drain pipe 44, thus achieving rapid drainage. The sealing plate 43 effectively prevents the seepage water from penetrating from the end of the collection groove 42 into the soil around the wall 2.

[0034] The laying of the waterproof cloth 45 enhances the side anti-seepage effect of the wall 2 and further reduces the risk of water seeping into the wall 2 from the side. The support blocks 46 enhance the structural stability of the installation groove 41, ensuring that it is not easily deformed or damaged during long-term use.

[0035] The use of the upper cover plate 47 further ensures that the water absorption plate 48 can be closely attached to the inside of the installation groove 41. The water absorption plate 48 can absorb the moisture around the wall 2, thereby reducing the possibility of leakage. When the water absorption plate 48 is saturated, it can be replaced by disassembling the upper cover plate 47, with simple operation and low maintenance cost.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
