Description

Technical Field

[0001] This invention relates to the field of underground continuous wall technology, and in particular to an underground wall cap beam structure. Background Technology

[0002] Diaphragm walls are constructed by excavating a rectangular trench of a certain depth using specialized trenching machinery with slurry lining. Underwater reinforced concrete is then poured into the trench to complete one unit of the wall. These units are connected using specific jointing methods to form a continuous underground reinforced concrete wall. The primary functions of diaphragm walls are water and soil retention, and they also serve as a structural load-bearing component.

[0003] For example, the existing patent with publication number CN110158630A discloses a circular diaphragm wall foundation for a long-span arch bridge in a region with a thick overburden layer. The foundation includes a circular diaphragm wall, a cap beam, an inner lining wall, a base plate, an arch seat, a cover plate, and pile foundations. The circular diaphragm wall comprises a Phase I trench segment and a Phase II trench segment, which are connected alternately to form a ring. The cap beam is arranged along the outline of the circular diaphragm wall and located at its top. The inner lining wall is tightly attached to the inner sidewall of the circular diaphragm wall. The base plate has a flat structure and is laid flat within the circular diaphragm wall. The arch seat is located on the upper surface of the base plate. The top of the cover plate is flush with the top surface of the cap beam. The pile foundations are located within the circular diaphragm wall.

[0004] However, the existing technology still has shortcomings. For example, after the diaphragm wall is completed, the cap beam needs to be removed, which wastes the guide wall concrete. It also requires secondary excavation and backfilling, which is time-consuming and labor-intensive. Summary of the Invention

[0005] In view of this, it is necessary to provide an underground wall cap beam structure to solve the technical problems in the existing technology that require the removal of the cap beam after the completion of the continuous wall construction, which wastes the guide wall concrete and requires secondary excavation and backfilling, which is time-consuming and labor-intensive.

[0006] To achieve the above-mentioned technical objectives, the present invention provides an underground wall cap beam structure, comprising:

[0007] Main body of the continuous wall;

[0008] The cap beam assembly includes a first cap beam and a second cap beam, the first cap beam and the second cap beam being located on both sides of the continuous wall body;

[0009] The support assembly includes a first support member, a first connector, and a second connector. The first connector is located inside the first cap beam, the second connector is located inside the second cap beam, and the first support member is located inside the continuous wall body. The two ends of the first support member are respectively connected to the first connector and the second connector.

[0010] Furthermore, the two ends of the first support member are threadedly connected to the first connector and the second connector, respectively.

[0011] Furthermore, the support assembly also includes a second support member disposed inside the first cap beam, the second support member being threadedly connected to the side of the first connector facing away from the first support member.

[0012] Furthermore, the support assembly also includes a third support member disposed inside the second cap beam, the third support member being threadedly connected to the side of the second connector facing away from the first support member.

[0013] Furthermore, the support assembly also includes a plurality of vertical support members disposed on the main body of the continuous wall. The plurality of vertical support members are arranged in parallel and spaced apart, and the vertical support members are arranged along the length extension direction of the main body of the continuous wall.

[0014] Furthermore, each of the vertical support members is welded to the first support member.

[0015] Furthermore, there are multiple first support members, first connectors, and second connectors. Multiple first support members are evenly arranged along the vertical direction of the continuous wall body. Each first support member is connected to the corresponding first connector and second connector at both ends. The vertical support member is connected to multiple first support members at the same time.

[0016] Furthermore, the support assembly also includes a first support mechanism and a second support mechanism with identical structures. The first support mechanism connects the continuous wall body and the first cap beam, and the second support mechanism connects the continuous wall body and the second cap beam.

[0017] Furthermore, the first support mechanism includes a first support plate, a second support plate, a first screw, and an auxiliary bracket. The first support plate is welded to the bottom of the first cap beam, and the second support plate is attached to the side of the continuous wall body. The first support plate and the second support plate are arranged perpendicular to each other, and the two ends of the auxiliary bracket are respectively connected to the first support plate and the second support plate.

[0018] Furthermore, the second support plate has a through hole extending through it along its thickness direction, and the main body of the continuous wall has a connecting groove, the connecting groove and the through hole being positioned corresponding to each other and communicating with each other.

[0019] Compared with the prior art, the beneficial effects of the present invention include:

[0020] The cap beam assembly of this invention can be retained as part of the underground wall, resulting in a larger overall volume of the diaphragm wall with better moisture resistance and compressive strength. Furthermore, it eliminates the need to remove the cap beam, saving guide wall concrete and eliminating the need for secondary excavation, thus saving time and labor. Additionally, the first and second connectors are respectively installed inside the first and second cap beams, and are connected by a first support member located inside the main body of the diaphragm wall. This effectively connects the main body of the diaphragm wall to the cap beam assembly via a support component, further reinforcing the connection between the diaphragm wall body and the cap beam assembly.

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0025] Please refer to Figure 1 and Figure 2 The present invention provides a cap beam structure 100, which is used to construct a continuous reinforced concrete wall underground for purposes such as water interception, seepage prevention, and load-bearing.

[0026] The underground wall cap beam structure 100 includes a continuous wall body 1, a cap beam assembly 2, and a support assembly 3. The cap beam assembly 2 is sleeved on the continuous wall body 1, and the support assembly 3 connects the continuous wall body 1 and the cap beam assembly 2 to ensure that the cap beam assembly 2 can be stably retained.

[0027] In underground wall construction, the cap beam assembly 2 is typically used to assist in the pouring of the main body 1 of the continuous wall, enabling the main body 1 of the continuous wall to form quickly. After the main body 1 of the continuous wall is formed, the cap beam assembly 2 usually needs to be removed. In this invention, after the main body 1 of the continuous wall is formed, the cap beam assembly 2 is retained and fixed by the support assembly 3, so that the cap beam assembly 2 becomes part of the underground wall, thereby increasing the stability of the underground wall and giving it stronger moisture resistance and compressive strength.

[0028] The cap beam assembly 2 includes a first cap beam 21 and a second cap beam 22, which are located on both sides of the main body 1 of the continuous wall. Both the first cap beam 21 and the second cap beam 22 are L-shaped to allow them to be more stably embedded in the ground. The space between the first cap beam 21 and the second cap beam 22 is used for casting the main body 1 of the continuous wall.

[0029] refer to Figure 1 The support assembly 3 includes a first support member 31, a first connector 32, and a second connector 33. The first connector 32 is located inside the first cap beam 21, the second connector 33 is located inside the second cap beam 22, and the first support member 31 is located inside the continuous wall body 1. Both ends of the first support member 31 are detachably connected to the first connector 32 and the second connector 33, respectively. When both ends of the first support member 31 are connected to the first connector 32 and the second connector 33, the cap beam assembly 2 is integrated with the continuous wall body 1. In other embodiments, the two ends of the first support member 31 can also be connected to the first connector 32 and the second connector 33 by welding or an integrally formed structure, making the connection more stable.

[0030] Figure 1 In the illustrated embodiment, the first connector 32 and the second connector 33 are respectively disposed near the side edges of the first cap beam 21 and the second cap beam 22. In other embodiments, the first connector 32 may be disposed near the inner center of the first cap beam 21, and the second connector 33 may be disposed near the inner center of the second cap beam 22. This is not limited here.

[0031] In one embodiment, the two ends of the first support member 31 are threadedly connected to the first connector 32 and the second connector 33, respectively. In other embodiments, the two ends of the first support member 31 can also be connected to the first connector 32 and the second connector 33 by other detachable means, such as a snap-fit ​​connection.

[0032] refer to Figure 2 The support assembly 3 also includes a second support member 34 disposed inside the first cap beam 21 and a third support member 35 disposed inside the second cap beam 22. The second support member 34 is threadedly connected to the side of the first connector 32 facing away from the first support member 31, and the third support member 35 is threadedly connected to the side of the second connector 33 facing away from the first support member 31. The addition of the second support member 34 and the third support member 35 is equivalent to further reinforcing the first cap beam 21 and the second cap beam 22, making the cap beam assembly 2 more stable and less prone to collapse.

[0033] Figure 2The support assembly 3 in the illustrated embodiment also includes a plurality of vertical support members 36 disposed on the continuous wall body 1. The plurality of vertical support members 36 are arranged in parallel and at intervals, and each vertical support member 36 is arranged along the length extension direction of the continuous wall body 1. The continuous wall body 1 is fixed by the plurality of vertical support members 36, making the structure of the continuous wall body 1 more stable and less prone to collapse.

[0034] In one embodiment, each vertical support 36 may also be welded to the first support 31, so that the first support 31 and the vertical support 36 are integrated, which can further enhance the stability of the connection between the cap beam assembly 2 and the continuous wall body 1.

[0035] In one embodiment, there are multiple first support members 31, first connectors 32 and second connectors 33. Multiple first support members 31 are evenly arranged along the vertical direction of the continuous wall body 1. The two ends of each first support member 31 are detachably connected to the corresponding first connectors 32 and second connectors 33. The vertical support member 36 connects multiple first support members 31 at the same time.

[0036] The support assembly 3 also includes a first support mechanism 37 and a second support mechanism 38 with identical structures. The first support mechanism 37 connects the main body of the diaphragm wall 1 and the first cap beam 21, and the second support mechanism 38 connects the main body of the diaphragm wall 1 and the second cap beam 22. Through the further reinforcement of the first support mechanism 37 and the second support mechanism 38, the main body of the diaphragm wall 1 can support the first cap beam 21 and the second cap beam 22, further enhancing the stability of the connection between the main body of the diaphragm wall 1 and the cap beam assembly 2.

[0037] refer to Figure 3 The first support mechanism 37 includes a first support plate 371, a second support plate 372, a first screw 373, and an auxiliary bracket 375. The first support plate 371 is installed at the bottom of the first cap beam 21 by the first screw 373. The second support plate 372 is attached to the side of the continuous wall body 1. The first support plate 371 and the second support plate 372 are arranged perpendicular to each other. The two ends of the auxiliary bracket 375 are respectively connected to the first support plate 371 and the second support plate 372. In other embodiments, the first support plate 371 can also be installed at the bottom of the first cap beam 21 by welding, which is not limited here.

[0038] The second support plate 372 has a through hole 374 extending along its thickness direction. The main body of the diaphragm wall 1 has a connecting groove 379 at the position corresponding to the through hole 374, and the connecting groove 379 is connected to the through hole 374. During construction, concrete will first flow into the through hole 374 and then into the connecting groove 379, so that the second support plate 372 is connected and fixed to the main body of the diaphragm wall 1.

[0039] The first support mechanism 37 also includes a third screw 376, a fourth screw 377, and an L-shaped bracket 378. The L-shaped bracket 378 rests against the connection between the first support plate 371 and the second support plate 372. The third screw 376 passes through the first support plate 371 and is threaded to the first cap beam 21. The fourth screw 377 passes through the second support plate 372 and is threaded to the continuous wall body 1, thus fixing the L-shaped bracket 378 and further enhancing the stability of the connection between the continuous wall body 1 and the cap beam assembly 2. The number of screws is not limited and can be one or more. The structure of the second support mechanism 38 is the same as that of the first support mechanism 37 and will not be described further here.

[0040] The construction sequence of the cap beam assembly of the present invention is as follows: first, the first cap beam 21 and the second cap beam are cast and formed; then, the lower half of the continuous wall body 1 is cast; and finally, the upper half of the continuous wall body 1 is cast to form the cap beam assembly.

[0041] The cap beam assembly of this invention can be retained as part of the underground wall, resulting in a larger overall volume of the underground wall and better moisture resistance and pressure resistance. Furthermore, the main body of the diaphragm wall is connected to the cap beam assembly via a support assembly, further reinforcing the connection between the main body and the cap beam assembly, ensuring a stable connection and preventing collapse.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
