Description

Technical Field

[0001] This application relates to the technical field of road construction, and in particular to a simple device for slipforming construction of road shoulders. Background Technology

[0002] Currently, the shoulder refers to the section on both sides of a highway from the edge of the road surface to the edge of the roadbed. Its function is to connect with the carriageway, act as lateral support for the road surface, provide space for emergency parking or storage of road maintenance materials, offer lateral clearance for safety barriers, and contribute to driver safety. Another function is to protect the roadbed slope, preventing roadbed collapse. The hard shoulder refers to the section adjacent to the carriageway and paved with a pavement structure of a certain strength (including the curb strip). It protects and supports the pavement structure, allows vehicles to detour and provides temporary parking for broken-down vehicles, can withstand the loads of vehicles, and facilitates the passage of non-motorized vehicles and pedestrians on mixed-traffic highways.

[0003] Concrete shoulders are commonly used in the construction of various types of roads. They are characterized by being continuous, repetitive, and simple in process. Traditional construction often involves manually erecting formwork in sections, then pouring concrete, and finally smoothing it by hand. This process requires purchasing a large number of formworks and spending a lot of manpower on formwork erection, smoothing, and demolding. The formwork also needs to be maintained. Although the process is simple, it is time-consuming, labor-intensive, and has a high construction cost. Summary of the Invention

[0004] To reduce construction costs, this application provides a simple device for slipforming construction of road shoulders.

[0005] This application provides a simple device for slipform construction of road shoulders, which adopts the following technical solution:

[0006] A simple device for slipforming road shoulder construction includes a slipform and a counterweight. The slipform slides along the road during use, and a shoulder forming space is formed on the slipform. A feed port for pouring concrete is opened on the side wall away from the road. The counterweight is set on the slipform to increase the gravity of the slipform.

[0007] By adopting the above technical solution, when constructing the road shoulder, a tractor is first used to move the sliding formwork, and concrete is poured into the feed inlet during the movement. The counterweight presses the sliding formwork firmly onto the road, forming a smooth road shoulder. The counterweight can effectively reduce the jumping of the sliding formwork. The sliding formwork, traction mechanism and counterweight work together to reduce the degree of manual intervention. It is not necessary to purchase a large number of templates, nor is it necessary to spend a lot of manpower on formwork erection, finishing and dismantling. Only the sliding formwork needs to be maintained, which reduces the construction cost.

[0008] Optionally, the sliding mold is provided with a hopper, and the hopper is connected to the feed port.

[0009] By adopting the above technical solution, the hopper facilitates the entry of concrete into the sliding mold during concrete pouring, enabling overfilling of the concrete, rapid filling of the shoulder forming space, quick shoulder formation, improved work efficiency, and reduced construction costs.

[0010] Optionally, it also includes a traction mechanism for driving the sliding mold to slide. The sliding mold includes a top plate, side plates and an adjustment assembly. The traction mechanism is connected to the top plate. Two side plates are slidably disposed on one side of the top plate. The adjustment assembly is disposed on the top plate and is used to drive the two side plates to slide synchronously.

[0011] By adopting the above technical solution, when the width of the road shoulder changes, the adjustment component can be used to drive the two side plates to slide. The side plates slide along the width direction of the top plate to achieve the adaptation of the sliding mold road shoulder forming space with the road shoulder. Through the above settings, the applicability of the device is improved.

[0012] Optionally, a maintenance mechanism is provided on the top plate. The maintenance mechanism includes a roll frame, a rotating shaft, a geotextile roll, a fixing component, and a transmission component. The roll frame is provided on the top plate, the rotating shaft is rotatably mounted on the roll frame, the geotextile roll is detachably mounted on the rotating shaft through the fixing component, and the transmission component is connected to the traction mechanism and drives the rotating shaft to rotate synchronously.

[0013] By adopting the above technical solution, the construction depth and height of the road shoulder are relatively shallow, and moisture is easily lost quickly, making it prone to cracking. After the road shoulder is laid, the transmission component drives the geotextile roll connected to the fixing component to rotate. The geotextile roll lays the geotextile on the road shoulder, covering the road shoulder and reducing the rapid loss of moisture. At the same time, the road shoulder laying and geotextile laying are carried out simultaneously, which facilitates the improvement of work efficiency and reduces construction costs. In addition, the geotextile roll rotates synchronously with the traction mechanism to achieve synchronous laying, reducing geotextile wrinkles and waste.

[0014] Optionally, a tensioning assembly is provided on the top plate, the tensioning assembly including a first tensioning roller, the first tensioning roller rotating on the top plate to drive the geotextile toward the road.

[0015] By adopting the above technical solution, when the sliding mold drives the roll frame to slide, the geotextile falls onto the road shoulder by the downward pressure of the first tensioning roller. The tensioning component provides the direction of the geotextile's fall and tensions the geotextile, so that the geotextile falls flat onto the road shoulder.

[0016] Optionally, the tensioning assembly further includes edge pressing rollers, which are rotatably mounted on the side plates and are used to press down the edges of the geotextile.

[0017] By adopting the above technical solution, when the sliding mold drives the roll frame to slide, the geotextile falls onto the road shoulder by the downward pressure of the first tension roller, and the edge pressing roller presses down on the edge of the geotextile, so that the geotextile also moisturizes the edge of the road shoulder, thereby improving the construction quality of the road shoulder.

[0018] Optionally, a water sprinkler assembly is provided on the top plate. The water sprinkler assembly includes a water sprinkler pipe, which is disposed on the top plate and parallel to the axis of the geotextile roll. The water sprinkler pipe has a water outlet and is connected to a water source on the traction mechanism.

[0019] By adopting the above technical solution, during the road shoulder laying process, the geotextile is laid on the road shoulder along with the road shoulder, and the water spray pipe sprays water from the water source onto the geotextile, keeping the geotextile moist, reducing the loss of water from the road shoulder, and at the same time reducing the water absorption of the road shoulder by the geotextile, making the road shoulder structure relatively stable, reducing rapid drying and cracking, and thus preserving the construction quality of the road shoulder.

[0020] Optionally, the sprinkler pipe is rotatably equipped with a shielding pipe, and the shielding pipe has at least one row of drainage holes corresponding to the water outlet. The top plate is equipped with a rotating assembly, which is connected to the shielding pipe and drives the shielding pipe to rotate.

[0021] By adopting the above technical solution, when the geotextile passes through the sprinkler pipe, the rotating component drives the shielding pipe to rotate. When the drainage hole on the shielding pipe corresponds to the water outlet hole on the sprinkler pipe, water is sprayed from the pipe onto the geotextile, making the geotextile relatively moist. This reduces excessive moisture, which would cause the road shoulder surface to become too wet, affecting the shape of the road shoulder and reducing the impact on construction quality. It also eliminates the need for secondary finishing, thus reducing construction costs.

[0022] Optionally, the rotating assembly includes a rotating ring and fixed teeth. The rotating ring is disposed on the shielding tube, and a plurality of fixed teeth are disposed on the rotating ring, with the plurality of fixed teeth being equally spaced along the axial direction of the rotating ring.

[0023] By adopting the above technical solution, during the laying of geotextile, the geotextile drives the fixed teeth to rotate, the fixed teeth drive the rotating ring to rotate, and the rotating ring drives the shielding pipe to rotate. The drainage holes and water outlets on the shielding pipe are constantly connected or disconnected to achieve intermittent watering, so that the geotextile maintains a certain level of moisture. Watering and laying are carried out simultaneously. When the work stops, watering and laying stop at the same time, reducing the occurrence of excessive water spraying and waste.

[0024] Optionally, the shielding tube has multiple shielding strips that slide along it. Each shielding strip has multiple switching holes corresponding to the drain holes. Sliding the shielding strips causes the switching holes to connect with or close the drain holes.

[0025] By adopting the above technical solution, the appropriate amount of water can be determined according to the external temperature and light environment. Then, the sliding shielding strip can be used to partially or intermittently block the drainage holes according to the amount of water, thereby adjusting the amount of water spraying. This allows the shaping cycle of the road shoulder to be maintained and reduces the impact on the construction quality of the road shoulder.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] 1. When constructing the road shoulder, the sliding formwork is first moved by a tractor, and concrete is poured into the feed inlet during the movement. The counterweight presses the sliding formwork firmly onto the road, forming a smooth road shoulder. The counterweight effectively reduces the jumping of the sliding formwork. The sliding formwork, traction mechanism and counterweight work together to reduce the degree of manual intervention. It is not necessary to purchase a large number of templates, nor is it necessary to spend a lot of manpower on formwork erection, finishing and dismantling. Only the sliding formwork needs to be maintained, which reduces the construction cost.

[0028] 2. When the geotextile passes through the sprinkler pipe, the rotating component drives the shielding pipe to rotate. When the drainage hole on the shielding pipe corresponds to the water outlet hole on the sprinkler pipe, water is sprayed from the pipe onto the geotextile, making the geotextile relatively wet. This reduces excessive water, which would cause the shoulder surface to become too wet, affecting the shape of the shoulder and reducing the impact on construction quality. No secondary finishing is required, thus reducing construction costs.

[0029] 3. The appropriate amount of water can be determined based on the external temperature and light conditions. Then, the sliding shielding strip can be used to partially or intermittently block the drainage holes according to the amount of water sprayed, thereby adjusting the amount of water sprayed. This allows the shaping cycle of the road shoulder to be maintained and reduces the impact on the construction quality of the road shoulder. Attached Figure Description

The slipform 100 has an inlet for pouring concrete. When constructing the road shoulder, the slipform 100 is connected to a tractor, and then the tractor drives the slipform 100 to slide. At the same time, concrete is delivered into the inlet by a tanker truck or other mixing equipment to form the road shoulder.

[0043] The sliding mold 100 has an inverted U-shaped shoulder forming space on the side closest to the ground. The feed inlet is connected to the forming space. A hopper 400 is fixedly connected to the sliding mold 100 and is connected to the feed inlet.

The corresponding volume of the hopper 400 is 0.5m³. The counterweight 200 is a counterweight block with a self-weight of 300kg. The hopper 400 is welded to the front end of the top of the U-shaped steel plate. The concrete feeds the U-shaped steel plate by its own weight. The counterweight 200 is placed in the middle and rear part of the back groove of the U-shaped steel plate. Together with the hopper 400, the U-shaped steel plate is ensured to be uniformly stressed.

[0045] During concrete shoulder construction, ensure the centerline of the U-shaped steel plate aligns with the centerline of the shoulder. Place the U-shaped steel plate on the shoulder to be constructed, and measure and mark the inner edge line of the shoulder. Adjust and fix the counterweight 200. Pour qualified concrete into the hopper 400, ensuring the device slides forward at a uniform speed of 3-4 m / min along the shoulder axis, continuously pouring concrete for the shoulder.

The maintenance mechanism 500 includes a roll frame 510 fixedly connected to the protective shell 140. Two rotating shafts 520 are rotatably connected to the roll frame 510. A fixing component 540 is provided at one end of the two rotating shafts 520 that are close to each other. The fixing component 540 includes two fixing cylinders 541 that are respectively fixedly connected to the side walls of the two rotating shafts 520 that are close to each other. The fixing cylinders 541 are round tubes. A fixing bolt 542 is threaded onto the round tube and extends into the fixing cylinder 541. A geotextile roll 530 can be placed between the two fixing cylinders 541. The fixing shaft of the geotextile roll 530 passes through the fixing cylinder 541 and is fixed by the fixing bolt 542. In order to facilitate the installation of the geotextile roll 530, a relief groove 543 is provided on the side wall of the fixing cylinder 541. The fixing shaft of the geotextile roll 530 slides into the fixing cylinder 541 through the relief groove 543.

[0051] The rotating shaft 520 passes through the roll frame 510 and is connected to the transmission assembly 550. The transmission assembly 550 is a chain sprocket or belt pulley that is connected to the traveling mechanism of the traction mechanism 300, so that the traveling mechanism and the rotating shaft 520 rotate synchronously.

A second tensioning frame 564 is fixedly connected to the side plate 120, and a pressing roller 562 is rotatably connected to the second tensioning frame 564. The pressing roller 562 is inclined and one end passing through the top plate 110 is inclined towards the top plate 110.

[0053] refer to Figure 6 , Figure 7 and Figure 8A water spraying assembly 570 is provided on the protective shell 140. The water spraying assembly 570 includes a connecting bracket 573 fixedly connected to the protective shell 140, and a water spraying pipe 571 fixedly connected to the connecting bracket 573. The water spraying pipe 571 is a blind pipe with one end closed. The water spraying pipe 571 can be connected to a water source, which is a water tank that can be installed on the traction mechanism 300. A drain hole 574 is opened on the water spraying pipe 571. The drain hole 574 is evenly spaced along the length of the water spraying pipe 571. 1. Tangent to the geotextile, and the drainage hole 575 is located on the upper side of the tangent position of the geotextile and the deflection angle is ten degrees; a shielding pipe 572 is sleeved on the sprinkler pipe 571, and at least one row of drainage holes 575 corresponding to the water outlet 574 is opened on the shielding pipe 572. The rotation of the shielding pipe 572 can drive the drainage holes 575 to connect with the water outlet 574. In order to facilitate the rotation of the shielding pipe 572, a rotating component 580 is provided on the shielding pipe 572, and the rotating component 580 drives the shielding pipe 572 to rotate.

[0054] The rotating assembly 580 includes a guide block 583 fixedly connected to the shielding tube 572. The guide block 583 is arranged along the length of the shielding tube 572. The rotating ring 581 is sleeved on the shielding tube 572 and slides along the guide block 583. Multiple fixing teeth 582 are fixedly connected to the rotating ring 581. The multiple fixing teeth 582 are evenly spaced along the circumference of the rotating ring 581. The fixing teeth 582 pad the geotextile, reducing the direct contact between the geotextile and the shielding tube 572. When the geotextile moves, it drives the fixing teeth 582 and the rotating ring 581 to rotate, thereby realizing the rotation of the shielding tube 572.

[0055] In order to reduce water waste, multiple shielding rings 584 are also fitted on the shielding pipe 572. The shielding rings 584 are located on the side opposite to each other of the two rotating rings 581. The shielding rings 584 include two half rings, which abut against each other. One end of each half ring is fixedly connected to a plug, and the other end is provided with a slot, in which the plug is inserted.

[0056] When the weather and humidity are different, the amount of water sprayed can be selected according to the actual environment. The shielding pipe 572 is provided with a sliding groove, which is connected to the drain hole 575. A shielding strip 576 is slidably connected in the sliding groove. The shielding strip 576 is provided with multiple switch holes, which correspond to the drain hole 575. The sliding shielding strip 576 can drive the switch holes to connect with or be misaligned to block the drain hole 575. It can also be used to adjust the water output.

[0057] The implementation principle of Embodiment 2 of this application is as follows: When pouring the road shoulder, the geotextile roll 530 is first installed on two fixed cylinders 541, and then the geotextile is pulled out and laid on the road shoulder. Then the concrete is poured into the hopper 400, and the concrete in the hopper 400 enters the forming space to form the road shoulder. As the road shoulder is laid, the rotating shaft 520 rotates, causing the geotextile to break the roll and be laid on the road shoulder through the shielding pipe 572 and the first tensioning wheel. The traction mechanism 300 drives the top plate 110 to slide, the geotextile continues to break the roll and drives the fixed tooth 582 to rotate, the fixed tooth 582 drives the rotating ring 581 to rotate, the rotating ring 581 drives the shielding pipe 572 to rotate, and the shielding pipe 572 drives the drainage hole 575 to connect with the water outlet hole 574 respectively. Then water is intermittently sprayed on the geotextile.

[0058] Depending on the actual external environment, the sliding shield 576 can be used to connect, close, or misalign the switch hole and the drain hole 575, thereby adjusting the water output and reducing water waste.

[0059] When the width of the road shoulder to be laid changes, the adjusting screw 134 can be rotated to move the slider 133, which in turn moves the sliding rod 131, which in turn moves the side plate 120, thus achieving the width adjustment.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
