Description

Technical Field

[0001] This invention belongs to the technical field of building component manufacturing and construction equipment, and more specifically, relates to a flexible interlocking connection deep and shallow connection underground continuous wall and rigid plate processing equipment. Background Technology

[0002] Diaphragm walls, as a common support structure in deep foundation pit engineering, are widely used in various civil engineering projects. In complex geological conditions or when adjacent to existing buildings, it is often necessary to use walls of different depths to connect shallow and deep sections in order to balance safety and economy.

[0003] Traditional rigid connection methods are prone to stress concentration at the joints when there is differential settlement or horizontal deformation between walls, leading to concrete cracking or joint failure. This affects the overall waterproofing and stability of the structure, and in some cases, the collapse of the deeper wall due to force majeure can cause significant deformation damage to the shallower wall. Furthermore, current technologies lack connection components that can effectively coordinate deformation between walls of different depths, provide reliable flexible tensile strength, and prevent the junction between deep and shallow walls from becoming a weak point in the structure.

[0004] Therefore, there is an urgent need for a new type of underground continuous wall connection structure that can adapt to deformation, effectively transfer loads, ensure connection reliability, and achieve controllable disconnection at critical moments. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a flexible interlocking connection device for processing diaphragm walls and rigid panels that connect deep and shallow sections. This device solves the problem in existing diaphragm walls where rigid connections at the joints between deep and shallow sections lead to stress concentration at the connection points, causing concrete cracking, joint failure, and severely impacting the overall structure's waterproofing and stability. Simultaneously, it addresses the issue where rigid connections exert strong tensile forces on the shallower wall when the deeper wall overturns due to external forces, triggering a chain reaction of damage.

[0012] In one embodiment of the present invention, the reinforcement component further includes: at least two first reinforcing ribs disposed on the outside of the inner connector and fixedly connected to the first rigid wall body, for improving the connectivity between the inner connector and the first rigid wall body; and at least two second reinforcing ribs disposed on the outside of the outer connector and fixedly connected to the second rigid wall body, for improving the connectivity between the outer connector and the second rigid wall body.

[0013] In one embodiment of the present invention, the interlocking assembly further includes: at least two connecting ribs, which are evenly disposed on the outer sides of the two mating members and respectively fixedly connected to the inside of the first rigid wall and the second rigid wall, for improving the overall connectivity between the flexible connector and the first rigid wall and the second rigid wall.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see Figures 1 to 4 This illustration shows the structure of a flexible interlocking underground continuous wall with shallow and deep connections in an exemplary embodiment of this application, including: a wall foundation component 1 and a flexible connecting wall 2, wherein... The wall foundation component 1 includes: a first rigid wall 111 and a second rigid wall 112 with their top ends at the same horizontal line, wherein the depth of the first rigid wall 111 is greater than that of the second rigid wall 112. A flexible connecting wall 2, disposed between the first rigid wall 111 and the second rigid wall 112, is used to provide a horizontal connection between the two. The flexible connecting wall 2 includes: The height difference pad 200 is fixedly connected to the first rigid wall 111 to make the bottom end of the flexible connector 210 and the bottom end of the second rigid wall 112 at the same horizontal line. The flexible connector 210 is disposed on the top of the height difference pad 200 and is fixedly connected to the first rigid wall 111 and the second rigid wall 112, and is used to provide flexible horizontal tension for the first rigid wall 111 and the second rigid wall 112.

[0025] In complex geological conditions or near existing buildings, walls of different depths are often used to connect shallow and deep sections to balance safety and economy. However, the wall material used in actual construction is concrete, which can be considered a rigid material. Therefore, if geological settlement or other reasons cause deformation between the two walls, cracks may appear at the connection. In extreme cases, if one wall collapses, it may directly cause the other wall to collapse as well. To solve this problem, in one embodiment of the present invention, a flexible connecting wall 2 is set between the first rigid wall 111 and the second rigid wall 112. This design can effectively transfer the horizontal load between the shallow and deep walls, and at the same time, the deformation capacity of the flexible connecting wall 2 can absorb and release the stress caused by differential settlement or lateral displacement, significantly reducing stress concentration and the risk of concrete cracking at the connection, and improving the stability and reliability of the overall structure. Meanwhile, although the connection between the flexible connecting wall 2 and the first rigid wall 111 and the second rigid wall 112 is a fixed connection, its strength is insufficient to support its stable connection between the first rigid wall and the second rigid wall under extreme conditions. This also gives the connection the ability to undergo controllable deformation or even breakage under extreme working conditions, thereby avoiding catastrophic chain damage caused by the instability of the deep wall, and taking into account both the safety under normal conditions and the resilience during disasters.

[0026] Please see Figures 1 to 3 This application illustrates a wall foundation component 1 for a flexibly interlocking underground continuous wall that connects deep and shallow sections in an exemplary embodiment of the present application. Its structure includes: a deep wall foundation pit 101, a shallow wall foundation pit 102, a first rigid wall 111, and a second rigid wall 112.

[0027] Deep wall foundation pit 101, used for the construction of the first rigid wall 111 in the next step; Shallow wall foundation pit 102 is used to construct a second rigid wall 112, the bottom of which is higher than the bottom of deep wall foundation pit 101.

[0028] The conventional construction method for connecting walls is as follows: a deep foundation pit is excavated on the selected foundation, a deep wall is built on the foundation pit, and then a shallower foundation pit is excavated on one side, and a shallower wall is built on the foundation pit to connect the walls of different heights on both sides. The construction method of this invention, however, involves setting up a flexible connecting wall 2 on the side of the foundation pit 102 where the shallow wall is to be built after the deep wall foundation pit 101 is constructed. Then, the first rigid wall 111 and the flexible connecting wall 2 are constructed as a single unit, and finally, the second rigid wall 112 is constructed. Compared with the traditional construction method, this method does not add many steps but achieves new results.

[0029] In one embodiment of the present invention, the flexible connecting wall 2 consists of a height difference pad 200 and a flexible connector 210. The height difference pad 200 is fixedly connected to the flexible connector 210 to maintain the flexible connector 210 at the same height as the second rigid wall 112, and also facilitates control of the height of the flexible connector 210 during construction. Furthermore, the flexible connector 210 is made of an elastic material, preferably rubber, which maintains sufficient elasticity for adequate cushioning and also possesses sufficient toughness to provide corresponding tensile force. Those skilled in the art can choose any material to achieve the same function.

[0030] Please see Figures 4 to 7 Furthermore, in one embodiment of the present invention, the flexible connector 210 includes: a first rigid plate 211, a flexible rubber layer 212, and a second rigid plate 213. The first rigid plate 211 is disposed on the height difference pad 200, and its top end is at the same height as the top end of the first rigid wall 111, and is fixedly disposed between the first rigid wall 111 and the flexible rubber layer 212. The flexible rubber layer 212 is fixedly connected between the first rigid plate 211 and the second rigid plate 213, and is used to connect the first rigid plate 211 and the second rigid plate 213, and to provide flexible buffer for the compression or pulling of the two. The second rigid plate 213 is disposed on the height difference pad 200, and its top end is at the same height as the top end of the second rigid wall 112, and is fixedly disposed between the second rigid wall 112 and the flexible rubber layer 212.

[0031] In practice, it is relatively difficult to fix the flexible connector 210 to the first rigid wall 111 and the second rigid wall 112, and the actual connection effect does not fully meet the requirements. Therefore, in one embodiment of the present invention, a first rigid plate 211 and a second rigid plate 213 are provided on the outside of the elastic flexible rubber layer 212 to compensate for this curve. The materials of the first rigid plate 211 and the second rigid plate 213 can be selected to be materials that can withstand the tensile force of the wall and are not easy to crack. For the convenience of on-site construction, a preferred material is steel plate, which is easy to process and transport, and its installation difficulty is relatively low. At the same time, the tensile strength and toughness of the steel plate of appropriate thickness can meet the requirements of the wall connection. The thickness of the first rigid plate 211 and the second rigid plate 213 can be determined by those skilled in the art based on actual needs. Fixing the flexible rubber layer 212 between the first rigid plate 211 and the second rigid plate 213 provides sufficient deformation buffer and sufficient tensile strength. The fixed connection between the first rigid plate 211 and the first rigid wall 111, and the connection between the second rigid plate 213 and the second rigid wall 112, can be fixed in any way that can be chosen by those skilled in the art.

[0032] Meanwhile, if both sides of the flexible rubber layer 212 are single planar structures, although the degree of adhesion between it and the first rigid plate 211 and the second rigid plate 213 is improved, the difficulty of fixing it will increase. Therefore, in order to facilitate the fixed connection of the three, in one embodiment of the present invention, the flexible connector 210 further includes: a convex connector 2120, which is disposed on both sides of the flexible rubber layer 212 and fixedly connected to the first rigid plate 211 and the second rigid plate 213, in order to improve the shear resistance of the flexible rubber layer 212 and improve the connection effect with the first rigid plate 211 and the second rigid plate 213.

[0033] The convex connector 2120 can be any convex shape. In actual use, those skilled in the art can choose a suitable shape to fix the first rigid plate 211, the second rigid plate 213 and the flexible rubber layer 212 in any way. For example, bolt holes can be reserved in the flexible rubber layer 212, and the first rigid plate 211 and the second rigid plate 213 can be fixed in the middle of the two with bolts to achieve the effect of combining rigidity and flexibility.

[0034] Furthermore, if the stability is simply achieved through a fixed connection of the three components, it will inevitably be inferior to a more integrated design. Therefore, in one embodiment of the present invention, the bottom ends of the first rigid plate 211 and the second rigid plate 213 are connected by a rigid bridge 215. After connecting the first rigid plate 211 and the second rigid plate 213 through the rigid bridge 215, the flexible rubber layer 212 is directly placed between the first rigid plate 211 and the second rigid plate 213 that constitute the whole, and its stability will be further improved. At the same time, when it is placed on the height difference pad 200, the rigid bridge 215 should be fixedly connected to the height difference pad 200. This structure can keep the flexible connecting wall 2 under the stress of the two side walls, which will greatly reduce the damage to the two side walls caused by the flexible connecting wall 2 itself. If the connecting bridge is placed at the top, the flexible connecting wall 2 will be continuously lifted upward by the shaking of the two side walls, which will greatly damage the connection stability between the flexible connecting wall 2 and the first rigid wall 111 and the second rigid wall 112, and in severe cases, it will cause the two side walls to crack.

[0035] Furthermore, to ensure the overall tensile strength of the flexible connecting wall 2 and the first rigid wall 111 and the second rigid wall 112, while also providing the connection with the ability to undergo controllable deformation or even breakage under extreme working conditions, in one embodiment of the present invention, the flexible connecting body 210 further includes: a reinforcing component 220 composed of an inner connector 221 and an outer connector 222. The inner connector 221 is fixedly connected to the outer side of the first rigid plate 211 and both sides of the flexible rubber layer 212, and is partially fixedly connected to the second rigid plate 213. It is also nested inside the outer connector 222 to enhance the overall tensile strength of the first rigid plate 211, the flexible rubber layer 212 and the outer connector 222. The outer connector 222 is disposed on the outside of the second rigid plate 213 and nested on the outside of the inner connector 221, and is used to enhance the overall tensile strength of the inner connector 221 and the second rigid plate 213. The inner connector 221 and the outer connector 222 are nested together by toothed engagement, and a buffer space of a preset distance is reserved.

[0036] By installing reinforcing components 220 on the outer sides of the flexible rubber layer 212, the first rigid plate 211, and the second rigid plate 213, which can disconnect under severe tensile force (i.e., when the tensile force on both sides exceeds a preset tensile limit), planned separation is achieved to protect the safety of the remaining wall structure. The reinforcing components 220 consist of inner connectors 221 and outer connectors 222, which are fixed together by toothed grooves. The number and shape of the toothed grooves are not limited; those skilled in the art can choose appropriate numbers and sizes to achieve the same purpose. The advantage of this design is that, under normal conditions, within the normal design load range, the wall at the connection point will not undergo significant changes. Instead, the flexible connecting wall 2 will buffer this deformation process through deformation. Simultaneously, a preset buffer space is reserved at the toothed grooves to prevent abnormal detachment of the toothed grooves due to deformation during thermal expansion and contraction. Furthermore, after installing the reinforcing component 220, the first rigid plate 211 inside it can be integrated with the inner connector 221, and the second rigid plate 213 can be integrated with the outer connector 222. In this design, the deformation buffering capacity of the flexible rubber layer 212 is not affected, but its overall stability is further improved. Moreover, since the reinforcing component 220 is symmetrical about the mid-plane of both walls, and the clamping direction of the toothed grooves is symmetrically distributed, it exhibits relatively stable performance in response to stress changes in various directions of the wall, and will not experience unexpected detachment under normal loads.

[0037] However, a single smooth connection surface will inevitably affect the fixed connection effect between the reinforcing component 220 and the first rigid wall 111 and the second rigid wall 112. Therefore, in one embodiment of the present invention, the reinforcing component 220 further includes: At least two first reinforcing ribs are disposed on the outside of the inner connector 221 and fixedly connected to the first rigid wall 111 to improve the connectivity between the inner connector 221 and the first rigid wall 111. At least two second reinforcing ribs are disposed on the outside of the external connector 222 and fixedly connected to the inside of the second rigid wall 112 to improve the connectivity between the external connector 222 and the second rigid wall 112.

[0038] By adding first and second reinforcing ribs fixed inside the first rigid wall 111 and the second rigid wall 112 to the outside of the inner connector 221 and the outer connector 222, sufficient connection contact surface can be provided for the connection between the reinforcing component 220 and the first rigid wall 111 and the second rigid wall 112, effectively improving the connection effect. At the same time, the number of first and second reinforcing ribs can be determined by those skilled in the art according to actual needs. Furthermore, the first and second reinforcing ribs can be selected in any shape, and several tooth structures can be set on them to improve the connection effect. Multiple first and second reinforcing ribs are not limited to being arranged in parallel. Those skilled in the art can choose any direction of arrangement to improve the ability of the flexible connecting wall 2 to resist stress in multiple directions.

[0039] Furthermore, the inner connector 221 and the outer connector 222 are nested. Although the inner connector 221 is smaller than the outer connector 222, it is not easy to install during actual construction because it needs to engage the tooth groove. Therefore, in a specific embodiment of the present invention, the flexible connector 210 further includes an engagement component 230, which consists of two identical mating parts symmetrical about the center of the flexible rubber layer 212, disposed on the outside of the first rigid plate 211, the flexible rubber layer 212 and the second rigid plate 213, forming a tenon and mortise structure, and reserving a buffer space of a preset distance to enhance the overall tensile strength of the first rigid plate 211, the flexible rubber layer 212 and the second rigid plate 213.

[0040] The design of the interlocking component 230 is also that two identical mating parts are engaged through toothed grooves. When subjected to tensile forces on both sides that exceed the preset load, they can be separated in a planned manner. However, their installation directions are opposite. Therefore, during installation, the toothed grooves on both sides can be easily engaged by transporting in only one direction without any effort. Through the internal first rigid plate 211, second rigid plate 213, and flexible rubber layer 212, a tenon and mortise structure can be formed, which forms a stable connection structure while retaining the controllable separation capability.

[0041] Similarly, the fixed connection between the mating component and the first rigid wall 111 and the second rigid wall 112 also needs further improvement, just as the principle of the aforementioned reinforcing component 220 is. Therefore, in one embodiment of the present invention, the interlocking component 230 further includes: At least two connecting stiffeners 214 are evenly arranged on the outside of the two mating parts and are respectively fixedly connected to the inside of the first rigid wall 111 and the second rigid wall 112 to improve the overall connectivity between the flexible connector 210 and the first rigid wall 111 and the second rigid wall 112.

[0042] By connecting the stiffening rib 214 to the first rigid wall 111 and the second rigid wall 112, the connection effect between the interlocking component 230 and the first rigid wall 111 and the second rigid wall 112 can be improved. Simultaneously, because the two mating parts are symmetrical about the flexible rubber layer 212, the clamping direction of the tooth grooves is the same, and the positions of the tooth grooves and teeth are the same for both mating parts. To allow sufficient space for the tooth grooves, the wall thickness on the tooth groove side of the mating part is larger, and the wall thickness on the tooth side is smaller. This is to accommodate the positive forces from both sides of the first and second rigid walls. Under axial load, the deformation of thick and thin walls will inevitably differ. The thinner wall side is more prone to greater deformation, which may lead to abnormal separation of the teeth from the grooves. Therefore, the location of the connecting stiffener 214 can be adjusted as needed, placing it more towards the thicker side of the mating part. This allows the thicker wall side, which is less prone to deformation, to bear more of the positive tensile force from both sides of the first and second rigid walls, thus better preventing abnormal separation of the teeth. Alternatively, the problem of different deformation can be solved by increasing the wall thickness of the mating part or by selecting a material that is less prone to deformation.

[0043] Furthermore, since the two mating parts are symmetrical about the flexible rubber layer 212 and the clamping direction of the tooth groove is the same, the tension at a specific angle may cause the tooth groove to disengage abnormally. Therefore, in one embodiment of the present invention, the connecting rib plate 214 is inclined and its outer side is offset towards the thin wall of the mating part.

[0044] by Figure 6 For example, if the right-side mating part is subjected to an upward pulling force, the thick wall is not easily deformed and the thin wall will be further tightened, so there will be no abnormal detachment problem. However, if the right-side mating part is subjected to a downward pulling force, although the thick wall is not easily deformed and does not easily detach, the thin wall is easily deformed, which will cause it to detach abnormally upward. Therefore, in order to solve this problem, the connecting stiffener 214 needs to be set at an angle, with its outer side offset towards the thin wall of the mating part. That is, the connecting stiffener 214 is set at an angle towards the side of the thin wall that is more easily deformed. When the right-side mating part is also subjected to a downward pulling force, the inclined connecting stiffener 214 will first bear part of the pulling force and generate part of the deformation to offset this part of the pulling force, which greatly reduces the impact of the downward pulling force on the thin wall.

The mechanism frame 321 is fixedly mounted on the horizontal processing table 300; The motor 322 is mounted on the frame 321 and is connected to provide power for the T-shaped processing head 323 to process the rigid workpiece 310.

[0046] There are one or more sliding clamping blocks. In use, the rigid workpiece to be processed is placed between the sliding clamping blocks. A stepper motor 322 drives a horizontal lead screw to rotate, causing the sliding clamping blocks to move along the lead screw direction, ultimately moving the rigid workpiece 310 to move along the lead screw direction. A downward-facing motor 322 is mounted on the frame of the machining mechanism 320. A U-shaped machining head 323 is mounted on the motor 322. When the motor 322 rotates, it drives the U-shaped machining head 323 to rotate. When the rigid workpiece 310 moves with the sliding clamping blocks to below the motor 322, the U-shaped machining head 323 will machine a U-shaped groove in the rigid workpiece 310, such as... Figure 9 As shown, if its bottom is completely cut open, a first rigid plate 211 and a second rigid plate 213 are obtained. If it is not cut open, a first rigid plate 211 and a second rigid plate 213 constituting a whole are obtained. The thickness of its bottom can be determined by those skilled in the art according to actual needs.
