Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to an anti-cross-hole device for the construction of double-span underground continuous walls. Background Technology

[0002] During the construction of double-panel diaphragm walls, cross-holes are a common construction problem. This is mainly because during the concrete pouring process, grout can easily leak through the gaps between the wall panels or the reserved holes, causing adjacent panels to connect. This affects the structural integrity and construction quality of the diaphragm wall, and in severe cases, it can lead to rework, increasing construction costs and time.

[0003] Currently, most existing anti-cross-hole devices are fixed structures, unable to be flexibly adjusted according to the concrete pouring process. They either only achieve sealing and leak prevention, failing to ensure air circulation to accelerate concrete drying, or have a single splicing method, making it difficult to flexibly assemble according to the actual relative positions of the wall surface, and causing mutual interference after splicing, which is detrimental to subsequent rebar installation. Furthermore, the splicing components of existing devices are mostly fixed and non-removable structures. When rebar installation is required, the entire device must be disassembled or the splicing structure damaged, making the operation cumbersome and inefficient. To address the shortcomings of existing technologies, there is an urgent need for an anti-cross-hole device for double-span diaphragm wall construction that can flexibly adapt to construction needs, balance anti-cross-hole protection and construction convenience, and can be used in conjunction with rebar installation, thus overcoming the deficiencies of existing technologies. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes an anti-cross-hole device for the construction of double-span underground continuous walls.

[0005] The technical solution for achieving the objective of this invention is as follows: a device for preventing cross-hole leakage during the construction of a double-span underground continuous wall, comprising a steel plate, a leak-proof component, and a plug-in component; side rods are fixedly installed on both sides of the steel plate, and a plurality of plug holes are provided on the steel plate for splicing with the side rods, the plurality of plug holes being arranged at equal intervals; the leak-proof component includes a hinge, a cover plate, and fixing screw holes, the cover plate being hinged to the steel plate, the fixing screw holes being respectively opened on the steel plate and the cover plate, bolts passing through the fixing screw holes to fix the cover plate and the steel plate in close contact, and the cover plate being relatively thin, the overall thickness of the cover plate after being attached to the steel plate being similar to the thickness of the steel plate itself; the plug-in component includes a plug rod, a plug... The steel plate has slots, threaded slots, and bottom threads. The slots are located on the side of the steel plate, and the threaded slots are evenly spaced on the steel plate. The bottom end of the insertion rod has a bottom thread that matches the threaded slot. The insertion rod is inserted into the threaded slot through the bottom thread, and the insertion rod can also be inserted into the slot of another steel plate to achieve splicing of two steel plates. The cover plate can be fastened to seal all insertion holes, or it can be removed to leave the insertion holes open. The insertion rod can be removed from the threaded slot. The threaded slot after removing the insertion rod can be used to insert reinforcing bars and fix the reinforcing bars by pouring concrete or cement. Multiple steel plates are spliced ​​together by side rods cooperating with insertion holes or insertion rods cooperating with slots to prevent cross-holes during the construction of double-span diaphragm walls.

[0006] Furthermore, the side rod and the steel plate are integrally formed, and the size of the side rod matches the size of the insertion hole, ensuring stable splicing of the steel plate after the side rod is inserted into the insertion hole.

[0007] Furthermore, the size of the cover plate matches the distribution area of ​​the insertion holes on the steel plate, ensuring that the cover plate can completely seal all insertion holes after being fastened to the steel plate, preventing concrete leakage.

[0008] Furthermore, the fixing screw holes are symmetrically arranged on the steel plate and the cover plate, and the number of fixing screw holes is at least one, to ensure the stability of the cover plate and the steel plate being fixedly attached.

[0009] Furthermore, the threaded grooves are arranged in a matrix with equal spacing on the steel plate, and the number of threaded grooves matches the number of insert rods, so the installation position of the insert rods can be selected according to the splicing requirements.

[0010] Furthermore, the length of the insertion rod matches the depth of the slot. After the insertion rod is inserted into the slot, the sides of the two spliced ​​steel plates fit tightly together, preventing concrete leakage caused by the splicing gap.

[0011] Furthermore, the cover plate is made of thin steel plate of the same material as the steel plate to ensure the structural strength of the cover plate and to ensure the consistency of thickness after it is bonded to the steel plate.

[0012] The significant advantages of this invention compared to existing technologies are:

[0013] Firstly, in this invention, by setting up a leak-proof component, the state of the cover plate can be flexibly adjusted according to the concrete pouring situation. When there is a risk of concrete leakage through the hole, the cover plate is fixedly attached to the steel plate, which can completely seal the insertion hole on the steel plate and prevent concrete from leaking through the insertion hole. When the angle of the wall is not likely to cause leakage, the cover plate is removed to open the insertion hole, which does not affect the construction and can also achieve air circulation, accelerate the drying of concrete, and take into account both preventing leakage and construction efficiency.

[0014] Secondly, in this invention, by setting side rods on both sides of the steel plate and opening slots on the side, combined with the insertion holes and detachable insertion rods on the steel plate, two splicing methods are provided. Moreover, the insertion holes and threaded grooves are arranged at equal intervals, so that multiple steel plates can be adjusted to their relative splicing positions according to the relative positions of the wall, avoiding mutual interference during splicing, and adapting to the construction needs of walls with different angles and sizes.

[0015] Thirdly, in this invention, the insertion rod is spirally connected to the threaded groove on the steel plate through the bottom thread, which can not only stably insert into the slot of another steel plate to achieve splicing and ensure the overall stability after splicing, but also flexibly disassemble. After the insertion rod is removed, the threaded groove can be directly used to insert steel bars and fix them with concrete or cement, without the need to open additional steel bar installation holes, simplifying the construction process and improving construction efficiency.

[0016] Fourthly, in this invention, the cover plate is made of thin steel plate of the same material as the steel plate, and the overall thickness after being bonded to the steel plate is similar to the thickness of the steel plate itself, so as to avoid the cover plate protruding and affecting the fit during construction; the side rod and the insertion hole are matched in size and the fixing screw holes are symmetrically arranged, which further ensures the structural stability and reliability of the device. The overall structure is simple, easy to disassemble and assemble, and suitable for large-scale promotion and use. Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides an improved anti-cross-hole device for the construction of double-span diaphragm walls. The technical solution of this invention is as follows:

[0027] like Figures 1-5 As shown, an anti-cross-hole device for the construction of a double-span underground continuous wall includes a steel plate 1, an anti-leakage component 4, and a plug-in component 5. Side rods 2 are fixedly installed on both sides of the steel plate 1. The side rods 2 are cuboid rods. Several plug holes 3 are provided on the steel plate 1 to facilitate splicing with the side rods 2. The side rods 2 can be directly inserted into the plug holes 3, and basic fixation is achieved using static friction. For a more robust fixation, cement or concrete can be poured. The plug holes 3 are arranged at equal intervals. The anti-leakage component 4 includes a hinge 41, a cover plate 42, and fixing screw holes 43. The cover plate 42 is hinged to the steel plate 1 via the hinge 41. Fixing screw holes 43 are respectively provided on the steel plate 1 and the cover plate 42. Bolts passing through the fixing screw holes 43 can fix the cover plate 42 to the steel plate 1 in a close fit. The cover plate 42 is relatively thin, and the overall thickness of the cover plate 42 after being fitted with the steel plate 1 is similar to the thickness of the steel plate 1 itself. The plug-in component 5 includes a plug rod 51, a slot 52, and a threaded groove 5. The insertion rod 51 has a bottom thread 54 and a slot 52 on the side of the steel plate 1. Threaded grooves 53 are equally spaced on the steel plate 1. The bottom end of the insertion rod 51 is provided with a bottom thread 54 that matches the threaded groove 53. The top end of the insertion rod 51 is thinner and is used to insert into the slot 52, while the bottom end of the insertion rod 51 is thicker and has a bottom thread 54. The bottom thread 54 can be spirally embedded into the threaded groove 53. The insertion rod 51 is spirally inserted into the threaded groove 53 through the bottom thread 54. The insertion rod 51 can also be inserted into the slot 52 of another steel plate 1 to achieve splicing of two steel plates 1. The cover plate 42 can be fastened to seal all insertion holes 3, or it can be removed to leave the insertion holes 3 in an open state. The insertion rod 51 can be removed from the threaded groove 53. The threaded groove 53 after removing the insertion rod 51 can be used to insert reinforcing bars and fix the reinforcing bars by pouring concrete or cement. Multiple steel plates 1 are spliced ​​by the side rod 2 and the insertion hole 3 or by the insertion rod 51 and the slot 52 to prevent cross-holes during the construction of double-span underground continuous walls.

[0028] In this embodiment, the side rod 2 and the steel plate 1 are integrally formed, and the size of the side rod 2 matches the size of the insertion hole 3, ensuring that the steel plate 1 is stably spliced ​​after the side rod 2 is inserted into the insertion hole 3. Since the insertion hole 3 is located on the steel plate 1, the length of the insertion hole 3 is lower than the corresponding side length of the steel plate 1. Therefore, the length of the side rod 2 needs to be shorter than the side length of the corresponding side of the steel plate 1.

[0029] In this embodiment, the size of the cover plate 42 matches the distribution area of ​​the insertion holes 3 on the steel plate 1, ensuring that the cover plate 42 can completely seal all the insertion holes 3 after being fastened to the steel plate 1, preventing concrete leakage. The hinge 41 adopts an easy-to-disassemble style. Depending on whether the cover plate 42 needs to cover the insertion holes 3, the hinge 41 and the cover plate 42 can be installed or the combination can be removed.

[0030] In this embodiment, the fixing screw holes 43 are symmetrically arranged on the steel plate 1 and the cover plate 42, and the number of fixing screw holes 43 is at least 2, to ensure the stability of the fixed fit between the cover plate 42 and the steel plate 1. The fixing screw holes 43 are evenly distributed on the steel plate 1 and the cover plate 42. Only bolts and nuts with a size smaller than the fixing screw holes 43 need to be selected, pass through the fixing screw holes 43 and fix them, so the cover plate 42 and the steel plate 1 can be fixed together. Therefore, there is no size requirement for the bolts.

[0031] In this embodiment, the threaded grooves 53 are arranged in a matrix with equal spacing on the steel plate 1, and the number of threaded grooves 53 matches the number of insert rods 51. The installation position of the insert rods 51 can be selected according to the splicing requirements.

[0032] In this embodiment, the length of the insertion rod 51 matches the depth of the slot 52. After the insertion rod 51 is inserted into the slot 52, the sides of the two spliced ​​steel plates 1 fit tightly together, avoiding concrete leakage caused by the splicing gap.

[0033] In this embodiment, the cover plate 42 is made of the same thin steel plate as the steel plate 1 to ensure the structural strength of the cover plate 42 and at the same time ensure the consistency of thickness after it is attached to the steel plate 1.

[0034] The specific working method is as follows: the steel plate 1 and the cover plate 42 are hinged together by a hinge 41. Fixing screw holes 43 are opened on both the steel plate 1 and the cover plate 42. The cover plate 42 and the steel plate 1 can be fixed together by bolts. The cover plate 42 is relatively thin. When the cover plate 42 and the steel plate 1 are attached, the thickness is similar to the thickness of the steel plate 1 itself. During construction, multiple steel plates 1 and devices can be prepared. By inserting the side rods 2 on both sides of each steel plate 1 into the insertion holes 3 located on other steel plates 1, the splicing of each steel plate 1 can be realized. Multiple insertion holes 3 are opened on each steel plate 1. The multiple insertion holes 3 are arranged at equal intervals. Therefore, each pair of steel plates 1 can be spliced ​​in a variety of different relative positions, so that the steel plates 1 can be installed in different relative positions according to the relative position of the wall during construction.

[0035] During construction, depending on the concrete pouring situation, if there is a possibility of concrete leakage leading to cross-hole leakage, the cover plate 42 and the steel plate 1 can be fastened together to completely block the insertion holes 3 on the steel plate 1 to prevent the poured concrete from leaking out through the insertion holes 3. However, if the concrete construction wall surface is at an angle where concrete leakage is unlikely, the cover plate 42 can be directly removed, leaving the insertion holes 3 on the steel plate 1 in an open state. In this case, the insertion holes 3 can be used for air circulation to accelerate the drying of the concrete.

[0036] When splicing steel plates 1, to avoid mutual interference during the splicing and installation of multiple steel plates 1, in addition to inserting the side rods 2 on both sides of steel plate 1 into the insertion holes 3 on other steel plates 1, the splicing and installation of two steel plates 1 can also be achieved by inserting the insertion rod 51 on the steel plate 1 into the slot 52 on the side of other steel plates 1. That is, the splicing and installation between any two steel plates 1 can be achieved in two different ways. After multiple steel plates 1 are spliced ​​and installed, the reinforcing bars are installed according to the construction needs. The insertion rod 51 on each steel plate 1 can be removed, and the bottom end of each insertion rod 51 is provided with a bottom thread 54. A large number of threaded grooves 53 are set at equal intervals on the plate 1. Each insert rod 51 can be screwed into one of the threaded grooves 53. The insert rods 51 can be inserted into the slots 52 on other steel plates 1 to achieve splicing of steel plates 1. However, when it is necessary to install reinforcing bars, some insert rods 51 can be removed appropriately. After removing the insert rods 51, reinforcing bars can be inserted into the corresponding threaded grooves 53, and the reinforcing bars can be fixed by pouring concrete or cement. In summary, by splicing and installing multiple steel plates 1 and installing reinforcing bars as needed, it can be used to effectively prevent cross-hole situations during the construction of double-span underground continuous walls.
