Description

Technical Field

[0001] This invention relates to the technical field, specifically to a retaining wall for a mountain highway with a deep positioning structure and its construction method. Background Technology

[0002] Landslides or soil deformation and instability can occur on ordinary mountains and slopes due to rainwater erosion or geological movements, especially on mountain roads. When a landslide or slope collapses, it can affect the use of subsequent roads and pose significant safety hazards. Therefore, we need to construct retaining walls to support the first roadbed or slope. However, existing retaining walls still have certain safety hazards in some aspects:

[0003] A retaining wall structure, as described in application number CN202011518763.7, is characterized by comprising: a wall body and a base; a groove is provided on the top surface of the base; the wall body includes a plurality of spaced pipe piles, each pipe pile having an axial hollow channel, all pipe piles being inserted into the groove, and all pipe piles being arranged sequentially along the length of the groove; each pipe pile being connected to the base by reinforcing bars; concrete being poured into the axial hollow channel of each pipe pile; each pipe pile having a wood-grain pattern on its outer surface, the pipe pile being a prestressed concrete pipe pile; a plain concrete pad layer being laid on the bottom surface of the base; and geotextile being provided on the side of the retaining wall structure closest to the bank.

[0004] The retaining walls mentioned in the above documents are mostly vertical, and the angle between the wall and the ground cannot be adjusted. The slopes where the retaining walls need to be installed have complex and varied terrain and mountain angles. A fixed wall angle may not be able to support slopes in different environments, which has certain limitations.

[0005] For example, application number CN201520195601.2 describes a retaining wall, including a wall body and a base at the bottom of the wall. The wall body is a stepped structure composed of horizontal and vertical retaining walls. The structure is simple and can effectively prevent the landslide of soil and rocks. At the same time, it is conducive to drainage and prevents strong erosion of the wall by water. Anchor piles are set on the vertical retaining walls to effectively connect the wall body to the rock behind it. Fixed piles are set at the bottom of the base to increase the stability of the base and make the retaining wall more durable. Planting areas are set on both the horizontal and vertical retaining walls, providing space for greening and landscape design. The reinforced concrete structure can greatly reduce the thickness of the wall and reduce the cost.

[0006] The retaining walls mentioned in the above documents are mostly single walls with large cross-sections. When construction workers transport and install the walls, the large cross-sections may cause some inconvenience to transportation and construction. Furthermore, the splicing process between the walls is relatively complicated, which will reduce construction efficiency. In addition, the walls cannot be adaptively kept at a constant temperature according to temperature differences, which leads to certain limitations in their use.

[0007] Therefore, we propose a retaining wall for mountain roads with a deep positioning structure and its construction method to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide a retaining wall for a mountain road slope with a deep positioning structure and its construction method, so as to solve the problems in the prior art, such as the inability to adjust the angle between the wall and the ground, the cumbersome splicing process, which reduces the construction efficiency, and the inability to adaptively maintain a constant temperature according to temperature differences.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a retaining wall for a mountain road slope with a deep positioning structure and its construction method, comprising a base body, a connecting block, a retaining wall body, a wall groove and a rotating shaft. The connecting block is fixedly connected to the upper surface of the side end of the base body, and the rotating shaft is fixedly connected inside the connecting block. The retaining wall body is nested and connected to the outside of both sides of the rotating shaft, and the wall groove is opened inside the retaining wall body.

[0010] The base groove is formed on the upper surface of the base body, and a threaded rod is nested inside the base groove. A handle is threadedly connected to one side of the threaded rod, and a threaded sleeve is threadedly connected to the threaded rod.

[0011] A connecting piece, wherein the connecting piece is connected through to the side of the retaining wall, and the two sides of the connecting piece are nested with locking blocks, and the inner end of the locking blocks is fixedly connected with a push plate;

[0012] A connecting component is provided, which is connected through the side of the retaining wall. The connecting component has an airbag groove inside, and a folded airbag is attached to the inside of the airbag groove.

[0013] Preferably, a rotating rod is hinged above the threaded sleeve, and the other end of the rotating rod is hinged to one side of the retaining wall. The retaining wall forms a rotating structure with the rotating rod and the rotating shaft, and the threaded sleeve drives the rotating rod to rotate.

[0014] Preferably, a limiting rod is fixedly connected inside the base groove, and an auxiliary block is nested on the limiting rod. The upper surface of the auxiliary block is fixedly connected to the lower surface of the threaded sleeve. A limiting spring is fixedly connected to one side of the auxiliary block, and the other end of the limiting spring is fixedly connected to the inside of the base groove. The auxiliary block and the limiting rod form an elastic structure through the limiting spring, and the limiting rod will limit the threaded sleeve through the auxiliary block.

[0015] Preferably, one side of the push plate has an arc-shaped structure, and a sleeve rod is fixedly connected to the inner side of the push plate. An inner rod is nested inside the sleeve rod, and the other end of the inner rod is fixedly connected to the inside of the docking member. A return spring is fixedly connected inside the docking member, and the other end of the return spring is fixedly connected to the top of the push plate. The inner rod and the sleeve rod are connected through the return spring. The push plate is symmetrically distributed about the center point of the docking member, and the push plate will drive the locking block to move.

[0016] Preferably, the connecting member has a fixing groove inside, and the center of the fixing groove is located at the center position between the two push plates. A fixing rod is nested inside the fixing groove. The retaining wall has a connecting groove on its side, and the upper and lower ends of the connecting groove have locking grooves. The locking grooves are connected to the locking blocks. At the same time, a fixing groove is opened at the center of the connecting groove, and the locking blocks will lock into the locking groove.

[0017] Preferably, one side of the connecting member is fixedly connected to one side of the docking member, and the connecting member and the docking member are hollow cylindrical structures, and the connecting member and the docking member are coaxial and interconnected.

[0018] Preferably, the folding airbag is a ring structure when viewed from the front, and a push plate is fixedly connected to one side of the folding airbag, and a push rod is fixedly connected to the other end of the push plate. A sliding groove is opened inside the airbag groove, and a push plate is nested inside the sliding groove. The push plate forms a sliding structure with the folding airbag and the sliding groove, and the folding airbag will push the push plate to move.

[0019] Preferably, the other end of the push rod is fixedly connected to a movable plug, and a sealing ring is nested around the outer ring of the movable plug. The movable plug is a circular structure when viewed from the front. The diameter of the movable plug is smaller than the minimum diameter of the mating part and larger than the maximum diameter of the connecting part. The push rod will drive the movable plug to move.

[0020] A construction method for a retaining wall on a hillside of a mountain highway with a deep positioning structure, characterized by the following steps:

[0021] A: When construction workers need to install retaining walls to support slopes at different angles, they can install the inlay handle on the side of the threaded rod. Rotating the inlay handle will cause the threaded rod to rotate. When the threaded rod rotates, the threaded sleeve connected to the external thread will move laterally simultaneously. When the threaded sleeve moves, it will cause the auxiliary block to move laterally along the limit rod. At this time, the auxiliary block will limit the movement of the threaded rod. While the auxiliary block moves, it will compress the limit spring, which will apply an elastic force to the auxiliary block and buffer the force on the auxiliary block to a certain extent. When the threaded sleeve moves, the rotating rod will rotate in the threaded sleeve, thereby pushing the retaining wall to rotate. At this time, the construction workers can make the retaining wall fit the angle of the mountain.

[0022] B: When construction workers need to connect two retaining walls, they can insert the connecting piece into the connecting groove to achieve initial connection between the two retaining walls. At this point, the user can insert the fixing rod into the connecting groove and the fixing slot on the connecting piece, extending the fixing rod further into the mountainside for better fixation and support between the retaining wall and the mountain. When the fixing rod is inserted into the connecting piece, it will push the pushing plate to both sides, causing the pushing plate to move towards the side wall of the connecting piece. This push plate will then move the locking block outwards and into the slots at both ends of the connecting groove. The locking groove allows the two retaining walls to be more firmly connected. As the push plate moves, it drives the sleeve rod to slide along the inner rod. When the sleeve rod slides, it simultaneously limits the movement of the locking block to prevent the locking block from shifting. At the same time, the return spring buffers the force of the sleeve rod sliding. When it is necessary to disassemble the retaining wall, the fixing rod is removed, and the return spring pushes the sleeve rod to move inward. The sleeve rod simultaneously drives the locking block to move inward through the push plate. At this time, the locking block is not connected with the locking groove, which makes it easier for construction workers to disassemble the retaining wall to a certain extent.

[0023] C: When the temperature inside a single retaining wall is high, the folded airbags in the airbag grooves inside the connecting parts will expand due to heat. When the folded airbags expand, they will drive the push plate to move along the slide groove. The push plate will simultaneously drive the push rod, which will further push the movable plug to slide in the airbag groove until the airbag groove leaves the connecting parts and enters the interior of the connecting parts. At this time, the connecting parts and the connecting parts are connected, so that the heat-carrying airflow inside the individual retaining walls with high internal temperatures can be guided and kept at a constant temperature through the wall grooves.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) The mountain road half-slope retaining wall with deep positioning structure and its construction method are equipped with a rotating rod. When the construction personnel turn the embedded handle, the threaded rod will rotate, and the threaded sleeve will move on the threaded rod. At this time, the rotating rod will rotate synchronously under the action of the threaded sleeve. When the rotating rod rotates, it will push the retaining wall to rotate about the rotating axis. At this time, the angle between the retaining wall and the base body can be adjusted to a certain extent, so that the retaining wall is better suited to the slope of different terrain and supports it, thus expanding the adaptability of the retaining wall.

[0026] (2) The mountain road half-slope retaining wall with deep positioning structure and its construction method are equipped with a connecting part. When the construction personnel need to install two retaining walls, they only need to insert the connecting part between the two retaining walls into the connecting groove. At this time, the two retaining walls can be initially connected to a certain extent. When the construction personnel insert the fixing rod into the fixing groove, the fixing rod will squeeze the pushing plate, so that the pushing plate will drive the locking block into the locking groove, so that the two retaining walls can be more stably connected. At this time, it is convenient for the construction personnel to quickly and conveniently assemble the retaining walls, reducing the cumbersome degree of construction assembly. At the same time, the small area of ​​the retaining wall also facilitates the construction personnel to transport and install the retaining wall to a certain extent.

[0027] (3) The mountain road half-slope retaining wall with a deep positioning structure and its construction method are equipped with a movable plug. When the temperature inside a single retaining wall is high, the folded airbag in the airbag groove opened inside the connecting part will be heated and expanded. The folded airbag will drive the push plate to move along the slide groove. The push plate will drive the push rod at the same time. The push rod will further push the movable plug to slide in the airbag groove until the airbag groove leaves the connecting part and enters the interior of the docking part. At this time, the docking part and the connecting part are connected, so that the heat-containing airflow inside the single retaining wall with a high internal temperature can be guided and kept constant temperature through the wall groove.

[0046] A construction method for a retaining wall on a hillside of a mountain highway with a deep positioning structure includes the following steps:

[0047] A: When construction workers need to support the retaining wall 3 on slopes at different angles, they can install the inlay handle 8 on the side of the threaded rod 7. Rotating the inlay handle 8 will cause the threaded rod 7 to rotate. When the threaded rod 7 rotates, the threaded sleeve 9 connected by the external thread will move laterally. When the threaded sleeve 9 moves, it will drive the auxiliary block 10 to move laterally along the limiting rod 11. At this time, the auxiliary block 10 will limit the movement of the threaded rod 7. While the auxiliary block 10 moves, it will squeeze the limiting spring 12. The limiting spring 12 will then apply an elastic force to the auxiliary block 10, which will buffer the force on the auxiliary block 10 to a certain extent. When the threaded sleeve 9 moves, the rotating rod 13 will rotate in the threaded sleeve 9, thereby pushing the retaining wall 3 to rotate. At this time, the construction workers can make the retaining wall 3 fit with the angle of the mountain.

[0048] B: When construction workers need to connect two retaining walls 3, they can insert the connecting piece 14 into the connecting groove 16 to achieve initial connection of the two retaining walls 3. At this time, the user can insert the fixing rod 19 into the fixing groove 16 and the fixing slot 18 opened on the connecting piece 14, and continue to insert the fixing rod 19 into the mountainside to better fix and support the retaining wall 3 to the mountainside. When the fixing rod 19 is inserted into the connecting piece 14, the fixing rod 19 will press the pushing plate 23 to both sides, causing the pushing plate 23 to move towards the side wall of the connecting piece 14. At this time, the pushing plate 23 will drive the locking block 20 to move outward and enter the locking slots opened at both ends of the connecting groove 16. Within the groove 17, the two retaining walls 3 are more firmly connected. During the movement of the push plate 23, the sleeve rod 22 will slide along the inner rod 21. When the sleeve rod 22 slides, it will simultaneously limit the movement of the locking block 20 to prevent the locking block 20 from shifting. At the same time, the return spring 24 will buffer the force of the sleeve rod 22 sliding. When it is necessary to disassemble the retaining wall 3, the fixing rod 19 is taken out, and the return spring 24 will push the sleeve rod 22 to move inward. The sleeve rod 22 will simultaneously drive the locking block 20 to move inward through the push plate 23. At this time, the locking block 20 is not connected with the locking groove 17, which makes it easier for construction personnel to disassemble the retaining wall 3 to a certain extent.

[0049] C: When the temperature inside a single retaining wall 3 is high, the folded airbag 25 in the airbag groove 26 inside the connecting member 15 will expand due to heat. When the folded airbag 25 expands, it will drive the push plate 27 to move along the slide groove 28. The push plate 27 will simultaneously drive the push rod 29. The push rod 29 will further push the movable plug 30 to slide in the airbag groove 26 until the airbag groove 26 leaves the connecting member 15 and enters the interior of the docking member 14. At this time, the docking member 14 and the connecting member 15 are connected, so that the heat-carrying airflow inside the single retaining wall 3 with a high internal temperature can be guided and kept constant temperature through the wall groove 4.

When the threaded sleeve (9) moves, the rotating rod (13) will rotate in the threaded sleeve (9), thereby pushing the retaining wall (3) to rotate. At this time, the construction personnel can make the retaining wall (3) fit with the angle of the mountain. B: When the construction workers need to connect the two retaining walls (3), they insert the connecting piece (14) into the connecting groove (16). At this time, the two retaining walls (3) can be initially connected. At this time, the workers insert the fixing rod (19) into the connecting groove (16) and the fixing slot (18) opened on the connecting piece (14), and make the fixing rod (19) continue to be inserted into the mountain, so that the retaining wall (3) and the mountain are better fixed and supported. When the fixing rod (19) is inserted into the connecting piece (14), the fixing rod (19) will push the pushing plate (23) to both sides, so that the pushing plate (23) moves towards the side wall of the connecting piece (14). At this time, the pushing plate (23) will drive the locking block (20) to move outward and enter the locking slot opened at both ends of the connecting groove (16). (17) Inward, the two retaining walls (3) are more firmly connected. During the movement of the push plate (23), the sleeve rod (22) will slide along the inner rod (21). When the sleeve rod (22) slides, it will limit the movement of the locking block (20) to prevent the locking block (20) from deviating. At the same time, the return spring (24) will buffer the sliding force of the sleeve rod (22). When it is necessary to disassemble the retaining wall (3), take out the fixing rod (19). The return spring (24) will push the sleeve rod (22) to move inward. The sleeve rod (22) will simultaneously drive the locking block (20) to move inward through the push plate (23). At this time, the locking block (20) does not connect with the locking groove (17), which makes it easier for construction personnel to disassemble the retaining wall (3) to a certain extent. C: When the temperature inside a single retaining wall (3) is high, the folded airbag (25) in the airbag groove (26) inside the connecting piece (15) will expand due to heat. When the folded airbag (25) expands, the folded airbag (25) will drive the push plate (27) to move along the slide groove (28). The push plate (27) will simultaneously drive the push rod (29). The push rod (29) will further push the movable plug (30) to slide in the airbag groove (26) until the airbag groove (26) leaves the connecting piece (15) and enters the interior of the docking piece (14). At this time, the docking piece (14) and the connecting piece (15) are connected, so that the heat-carrying airflow inside the single retaining wall (3) with high internal temperature can be guided and kept constant temperature through the wall groove (4).
