Description

Technical Field

[0001] The utility model relates to the technical field of guide wall construction, in particular to a guide wall. Background Art

[0002] Before the underground continuous wall is trenched, a guide wall must be constructed. The guide wall is the key to ensuring the accuracy of the underground continuous wall position and the quality of the trenching. During construction, the guide wall often bears the static and dynamic loads of steel cages, conduits for pouring concrete, drilling rigs, etc., so it must be carefully designed and constructed before the formal construction of the underground continuous wall can be carried out.

[0003] The existing guide wall is made of concrete and is usually cast in situ at the construction site. However, the construction progress of this concrete guide wall is slow, the cast-in-situ reinforced concrete cannot be reused, the construction cost is high, and it needs to be demolished after construction is completed, which is a cumbersome process.

[0004] Another existing guide wall is made of steel, but this type of steel guide wall is usually hollow, resulting in a small weight and low structural strength. When subjected to vibration and load, it is prone to displacement and deformation, affecting construction safety and easily slowing down construction progress. Utility Model Content

[0005] In view of this, the utility model provides a guide wall to solve the problem that the existing concrete guide wall cannot be reused and the steel guide wall is prone to displacement and deformation.

[0006] In a first aspect, the present invention provides a guide wall, comprising:

[0007] A plurality of guide wall units, wherein adjacent guide wall units are detachably connected, and each guide wall unit is provided with a receiving cavity and a through hole, wherein the through hole is communicated with the receiving cavity;

[0008] The counterweight is adapted to enter the accommodating cavity through the through hole.

[0009] Beneficial effects: The guide wall includes several guide wall units and counterweights, and the adjacent guide wall units are detachably connected. When constructing the guide wall, the modular guide wall units can greatly reduce the space occupied by transportation. The guide wall units that have been manufactured in the factory are directly transported to the construction site as needed, and the guide wall units are assembled on site, so the construction is simple and fast. In addition, a accommodating cavity and a through hole are provided on the guide wall unit, and the counterweight can enter the accommodating cavity through the through hole. The on-site counterweighting method can reduce the dead weight of the guide wall unit, reduce the difficulty of transportation and construction, and increase the weight of the guide wall unit during construction by the counterweight, which can make the guide wall unit more stable after assembly, so that when the guide wall is subjected to vibration and load in subsequent construction, the possibility of displacement and deformation is effectively reduced, thereby ensuring the stability of the guide wall, and thus ensuring construction safety and progress. After the construction of the underground continuous wall is completed, the guide wall unit can also be recycled. This guide wall not only solves the problem of complex construction and non-recyclability of existing concrete guide walls, but also solves the problem of easy displacement and deformation of existing steel guide walls, which affects construction safety. This guide wall is easy to transport and construct, has high structural strength, can be recycled after construction, realizes green construction, and has great promotion value.

[0010] In an optional embodiment, a groove is provided at one end of the guide wall unit, and a protrusion is provided at the other end of the guide wall unit, and the protrusion is suitable for being inserted into the groove. The end of the guide wall unit provided with the groove or the protrusion is provided with a pin hole passing through the groove or the protrusion, and when the protrusions of adjacent guide wall units are inserted into the groove, the two pin holes are coaxial, and the pin shaft is inserted into the two pin holes.

[0011] Beneficial effect: When the guide wall units are spliced, they are connected through grooves and protrusions. By inserting the protrusions into the grooves, the connection difficulty of the guide wall units can be reduced. After the initial connection of two adjacent guide wall units is completed, the pin shaft is inserted into the two coaxial pin holes to preliminarily position the two adjacent guide wall units, which is convenient for subsequent assembly and effectively reduces the assembly difficulty of the guide wall.

[0012] In an optional embodiment, the side end surface of the wall guide unit that is perpendicular to both the horizontal plane and the splicing direction is L-shaped or rectangular.

[0013] Beneficial effect: By setting the side end faces of the guide wall units perpendicular to the horizontal plane and the splicing direction to be L-shaped or rectangular, the guide wall units can be formed into different shapes to meet construction needs. The guide wall units with L-shaped end faces can prevent gaps from being generated at the corners of the assembled guide wall units, making the connection tight and the structural strength high. Moreover, when the guide wall is recycled after the construction is completed, it is easy to disassemble, thereby improving construction efficiency.

[0014] In an optional embodiment, several of the guide wall units are connected in sequence to form a guide wall assembly, and several of the guide wall assemblies are detachably connected in sequence to form a guide wall body. Adjacent guide wall bodies are arranged in parallel and spaced apart to form grooves, or adjacent guide wall bodies are arranged vertically and detachably connected.

[0015] Beneficial effect: Guide wall components are formed by guide wall units, and various forms of guide walls are formed by different connections between the guide wall components. The above modular design makes the on-site assembly of the guide wall simple and quick, and also makes the structure of the guide wall diverse, which can be combined according to the needs of on-site construction, thereby improving the applicability of the guide wall.

[0017] Beneficial effect: The guide wall panel protects the end face of the guide wall that may come into contact with other construction equipment, thereby preventing the guide wall unit from being damaged. At the same time, it can strengthen the connection strength between the guide wall units and the guide wall components, making the structural strength of the guide wall body higher and avoiding deformation of the guide wall.

[0018] In an optional embodiment, the through hole is provided on the top wall guide panel.

[0019] Beneficial effect: The hole provided on the top surface makes it convenient for construction workers to deliver the counterweight into the accommodating cavity, thereby reducing the difficulty of construction.

[0020] In an optional embodiment, a side support is further included, which is arranged between two parallel and spaced guide wall bodies and at the end of the guide wall body, and the top surface of the side support is flush with the top surface of the guide wall body.

[0021] Beneficial effect: The hole provided on the top surface makes it convenient for construction workers to deliver the counterweight into the accommodating cavity, thereby reducing the difficulty of construction.

[0022] In an optional embodiment, it further includes an inner support, which is arranged between two parallel and spaced guide wall bodies.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0040] The following combination Figures 1 to 4 , describing an embodiment of the guide wall of the present utility model.

[0041] According to an embodiment of the present invention, a guide wall is provided, comprising a plurality of guide wall units 1 and a counterweight. Adjacent guide wall units 1 are detachably connected, each having a receiving cavity and a through hole 11 communicating with the receiving cavity. The counterweight is adapted to enter the receiving cavity through the through hole 11.

[0042] The guide wall provided in this embodiment includes several guide wall units 1 and counterweights, and adjacent guide wall units 1 are detachably connected. When constructing the guide wall, the modular guide wall units 1 can greatly reduce the space occupied by transportation. The guide wall units 1 that have been manufactured in the factory are directly transported to the construction site as needed, and the guide wall units 1 are assembled on site, so the construction is simple and fast. In addition, a accommodating cavity and a through hole 11 are provided on the guide wall unit 1, and the counterweight can enter the accommodating cavity through the through hole 11. The counterweight is performed on site to reduce the weight of the guide wall unit 1, and the difficulty of transportation and construction is reduced. The weight of the guide wall unit 1 during construction is increased by the counterweight, which can make the guide wall unit 1 more stable after assembly, so that when the guide wall is subjected to vibration and load in subsequent construction, the possibility of displacement and deformation is effectively reduced, thereby ensuring the stability of the guide wall, and thus ensuring construction safety and construction progress. After the construction of the underground continuous wall is completed, the guide wall unit 1 can also be recycled. This guide wall not only solves the problem of complex construction and non-recyclability of existing concrete guide walls, but also solves the problem of easy displacement and deformation of existing steel guide walls, which affects construction safety. This guide wall is easy to transport and construct, has high structural strength, can be recycled after construction, realizes green construction, and has great promotion value.

[0043] In one embodiment, the guide wall unit 1 is made of steel. The guide wall unit 1 made of steel has a high structural strength and is not easily deformed or damaged during construction.

[0044] In one embodiment, the counterweight is sand and gravel. Using sand and gravel as the counterweight is convenient and quick, and can be collected at the construction site. The sand and gravel can be easily fed into the accommodating cavity through the through hole 11 and can also be easily poured out from the through hole 11 after construction is completed. The construction difficulty is low, and after filling, it is not easy to shake, and the center of gravity is stable, ensuring the stability of the center of gravity of the guide wall. In other embodiments, the counterweight can also be an iron block, a prefabricated counterweight block, or water.

[0045] In one embodiment, the through hole 11 is square, and its size is 200 mm×200 mm. In other embodiments, the through hole 11 may also be circular.

[0046] In one embodiment, a groove 12 is provided at one end of the guide wall, and a protrusion 13 is provided at the other end of the guide wall. The protrusion 13 is adapted to be inserted into the groove 12. The ends of the guide wall provided with the groove 12 or protrusion 13 are each provided with a pin hole extending through the groove 12 or protrusion 13. When the protrusions 13 of adjacent guide wall units 1 are inserted into the groove 12, the two pin holes become coaxial, and the pins are inserted into the two pin holes. When the guide wall units 1 are spliced ​​together, they are connected via the groove 12 and protrusion 13. Inserting the protrusion 13 into the groove 12 can reduce the difficulty of connecting the guide wall units 1. After the initial connection of the two adjacent guide wall units 1 is completed, the pins are inserted into the two coaxial pin holes to preliminarily position the two adjacent guide wall units 1, facilitating subsequent assembly and effectively reducing the difficulty of guide wall assembly.

[0047] In one embodiment, the side end surfaces of the guide wall units 1 that are perpendicular to both the horizontal plane and the splicing direction are L-shaped or rectangular. By configuring the side end surfaces of the guide wall units 1 that are perpendicular to both the horizontal plane and the splicing direction as L-shaped or rectangular, the guide wall units 1 can be configured into various shapes to meet construction requirements. The L-shaped end surfaces of the guide wall units 1 prevent gaps from forming at the corners of the assembled guide wall units 1, resulting in a tight connection and high structural strength. Furthermore, upon completion of construction, when the guide wall is recycled, disassembly is facilitated, thereby improving construction efficiency.

[0048] In one embodiment, several guide wall units 1 are sequentially connected to form a guide wall assembly 2, and several guide wall assemblies 2 are sequentially and detachably connected to form a guide wall body 3. Adjacent guide wall bodies 3 are arranged parallel and spaced apart to form a groove, or are arranged perpendicularly and detachably connected to each other. Guide wall assemblies 2 are formed by guide wall units 1, and various guide wall configurations are formed by different connections between guide wall assemblies 2. This modular design simplifies and swifts on-site assembly of the guide wall, and also allows for a variety of guide wall structures that can be combined according to on-site construction needs, thereby improving the applicability of the guide wall.

[0049] In one embodiment, the guide wall assembly 2 is formed by combining L-shaped guide wall units 1. In addition to being connected by pins, the guide wall units 1 are also connected by bolts to enhance the connection strength and facilitate disassembly.

[0050] In one embodiment, the guide wall further includes guide wall panels 4, which are disposed on the top surface of the guide wall body 3 and on the side surface facing the other guide wall body 3. The guide wall panels 4 are detachably connected to the guide wall body 3. The guide wall panels 4 protect the end surfaces of the guide wall that may come into contact with other construction equipment, thereby preventing damage to the guide wall units 1. They also strengthen the connection strength between the guide wall units 1 and between the guide wall assemblies 2, thereby increasing the structural strength of the guide wall body 3 and preventing deformation of the guide wall.

[0051] In one embodiment, the guide wall panel 4 is supported by a 12 mm manganese plate, which has high structural strength and is wear-resistant.

[0052] In one embodiment, a through hole 11 is provided on the top surface of the guide wall panel 4. The through hole 11 provided on the top surface facilitates construction workers to insert the counterweight into the accommodating cavity, thereby reducing construction difficulty.

[0053] In one embodiment, the guide wall units 1, the guide wall assemblies 2, and the guide wall body 3 and the panel are all detachably connected by bolts and nuts. Among the bolts and nuts connecting the guide wall body 3 and the panel, the nuts are welded to the panel to improve the connection strength and reduce mortar leakage, and a round tube is arranged around the nut to further prevent mortar from entering.

[0054] In one embodiment, side supports 5 are further included. The side supports 5 are disposed between two parallel and spaced-apart guide wall bodies 3 and at the ends of the guide wall bodies 3. The top surfaces of the side supports 5 are flush with the top surfaces of the guide wall bodies 3. The side supports 5 enable force transmission between the two parallel and spaced-apart guide wall bodies 3. The two guide wall bodies 3 can provide mutual support, ensuring that the guide wall can adhere closely to the soil during construction without tipping over, while also increasing the overall structural strength of the guide wall.

[0055] In one embodiment, the guide wall further includes an inner support 6 disposed between two parallel and spaced guide wall bodies 3. The inner support 6 supports the middle portion of the guide wall body 3, thereby increasing the overall stability of the hoisting when the two assembled guide wall bodies 3 are hoisted, and reducing shaking and collision during the hoisting process.

[0056] In one embodiment, the inner support 6 is detachably connected to the guide wall body 3. Before the guide wall is constructed, the inner support 6 supports the guide wall body 3. The inner support 6 can support the middle portion of the guide wall body 3. When the two assembled guide wall bodies 3 are hoisted, the stability of the overall hoisting can be increased, and shaking and collisions during the hoisting process can be reduced. After the guide wall is hoisted, the inner support 6 needs to be removed to expose the groove between the two parallel and spaced guide wall bodies 3, making it easier for equipment to be installed in the groove.

[0057] In one embodiment, the guide wall unit 1 is further provided with a lifting hole 7, which is suitable for connecting to a lifting device. The lifting hole 7 can be connected to the lifting device, and the guide wall unit 1 can be easily transported by the lifting device, making it convenient for construction workers to align and assemble.

[0058] In one embodiment, a hanging hole 7 is provided on the top surface of the guide wall unit 1, and a hanging hook is provided in the hanging hole 7. The hanging hook can be connected to the lifting equipment. Setting the hanging hook in the hanging hole 7 is beautiful, simple, and safe, and avoids damage to equipment or construction personnel during construction.

[0059] In one embodiment, the hanging hole 7 is square, and the size of the hanging hole 7 is 300 mm x 300 mm. In other embodiments, the hanging hole 7 may also be circular.

[0060] According to an embodiment of the present invention, on the other hand, a construction method of an underground continuous wall is also provided, which uses the above-mentioned guide wall for construction, including: transporting the guide wall unit 1 to the construction site for assembly; excavating a foundation trench; placing the assembled guide wall unit 1 into the foundation trench; placing the counterweight into the accommodating cavity through the through hole 11; re-measuring the elevation of the guide wall; performing underground continuous wall grooving construction after confirmation; hoisting the guide wall and moving it to the next foundation trench, and repeating the operation.

[0061] The underground continuous wall construction method provided in this embodiment is constructed by the above-mentioned guide wall. The guide wall unit 1 is easy to transport and saves space. The assembly when transported to the site is simple and quick. It can also be combined according to construction needs. After the assembly is completed, the foundation trench is excavated on site, and the assembled guide wall unit 1 is placed in the foundation trench. The construction is simple and convenient. After the guide wall unit 1 is set, the counterweight is placed in the receiving hole. The counterweight increases the overall deadweight of the guide wall and increases the structural strength and stability of the guide wall. After the counterweight is set, the overall setting of the guide wall is completed. The elevation of the guide wall is re-measured to ensure the correct setting position of the guide wall. After confirmation, the grooving construction of the underground continuous wall can be started. After the construction is completed, the guide wall can be hoisted out and moved to the next foundation trench for recycling operation. It can also be disassembled and recycled and moved to another construction site in need. The underground continuous wall construction method provided in this embodiment solves the problems of slow construction progress, high construction cost, environmental pollution, etc. of traditional cast-in-place reinforced concrete guide walls, and realizes standardized production and recycling; it also solves the problem that existing steel guide walls are prone to displacement and deformation. During the entire installation and disassembly process, only excavators need to cooperate with manual labor, which improves construction efficiency.
