Description

Technical Field

[0001] This invention relates to the field of circular pipe culvert construction technology, and in particular to a mortar application device for circular pipe culverts. Background Technology

[0002] Circular pipe culverts are the most commonly used culvert structure type for highway subgrade drainage. The most common type is the reinforced concrete circular pipe culvert, which is composed of multiple pipes connected together. It not only has good mechanical properties, but also has a simple structure, is easy to construct, has a short construction period, and is low in cost.

[0003] During the construction of circular pipe culverts, a 1.5cm-2cm joint is typically left at the interface of two adjacent pipes. This joint must be properly waterproofed. Current technology involves applying a mortar strip manually using a steel trowel along the joint, ensuring the strip's thickness and width are controlled, and then manually finishing the edges to maintain the desired shape. However, this method relies entirely on manual control, resulting in low efficiency and difficulty in controlling the strip's thickness and width, impacting the overall waterproofing performance of the culvert. Furthermore, the appearance quality of the mortar strip is unreliable, potentially leading to cracking and water seepage during later use. Summary of the Invention

[0004] The purpose of this invention is to provide a mortar application device for circular pipe culverts, which alleviates the technical problems of existing mortar application methods that rely entirely on manual control of the construction process, resulting in low work efficiency, difficulty in controlling the thickness and width of the mortar application, affecting the overall waterproof performance of the circular pipe culvert, difficulty in guaranteeing the appearance quality of the mortar application, and potential cracking and water seepage during later use.

[0005] The mortar sealing device for circular pipe culverts provided by the present invention is used for sealing the joint of two pipes in a circular pipe culvert. It includes a bracket and two arc-shaped clamps connected to the bracket and arranged opposite to each other. The two arc-shaped clamps can approach each other to fit against the outer wall of the pipe.

[0006] Each of the arc-shaped clamps includes two spaced-apart stop plates. When the arc-shaped clamps are in contact with the outer wall of the pipe, the two stop plates form a mortar grout gap with the outer wall of the pipe.

[0007] Furthermore, the arc-shaped clamp also includes a connecting plate for connecting the two stop plates.

[0008] Furthermore, the mortar application device for the circular culvert also includes a driving mechanism. One end of the driving mechanism is connected to the arc-shaped clamp, and the other end of the driving mechanism is connected to the bracket, for driving the two arc-shaped clamps to move closer or further apart.

[0009] Furthermore, the drive mechanism includes a pull rope and a rotating wheel with a self-locking function;

[0010] The rotating wheel is rotatably connected to the bracket, one end of the pull rope is connected to the arc-shaped clamp, and the other end of the pull rope is wound around the rotating wheel.

[0011] Furthermore, the support includes a horizontally arranged crossbeam and two side beams respectively connected to both ends of the crossbeam;

[0012] The mortar application device for the circular culvert also includes a connecting structure, which includes two sliding members that are slidably connected to the crossbeam. Each sliding member is connected to an arc-shaped clamp at one end away from the support. When the driving mechanism drives the two arc-shaped clamps, the sliding member can slide along the length of the crossbeam.

[0013] Furthermore, the crossbeam is provided with a "T"-shaped groove extending along its length, and the end of the sliding member away from the arc-shaped clamp is provided with a protrusion corresponding to the "T"-shaped groove, the protrusion being slidably connected in the "T"-shaped groove.

[0014] Furthermore, the mortar application device for the circular pipe culvert also includes a clamping structure, which is disposed between the side beam and the arc-shaped clamp, and is used to lock and position the arc-shaped clamp that is attached to the pipe.

[0015] Furthermore, the clamping structure includes a snap-fit ​​component, one end of which is hinged to the side beam. The snap-fit ​​component has multiple toothed grooves, and the arc-shaped clamp has a snap-fit ​​portion corresponding to the toothed grooves. The snap-fit ​​portion cooperates with the toothed grooves to fix the arc-shaped clamp that is attached to the outer wall of the pipe.

[0016] Furthermore, the mortar applicator for the circular culvert also includes rollers disposed at the bottom of the support, so that the support and the arc-shaped clamp can move.

[0017] Furthermore, the roller is a swivel wheel.

[0018] The present invention provides a mortar sealing device for a circular culvert, used for sealing the joint between two pipes of a circular culvert. It includes a support and two arc-shaped clamps connected to the support and arranged opposite each other. The two arc-shaped clamps can approach each other to fit against the outer wall of the pipe. Each arc-shaped clamp includes two spaced-apart stop plates. When the arc-shaped clamp fits against the outer wall of the pipe, the two stop plates form a mortar sealing gap with the outer wall of the pipe.

[0019] In practical use, the two arc-shaped clamps are brought close together and aligned with the joints of the two adjacent pipes. They are then attached to the outer wall of the pipes, so that the joint between the two pipes is between the two stop plates. The two stop plates and the outer wall of the joint between the two pipes form a mortar banding gap. Finally, the construction workers fill the gap with mortar and smooth it. The mortar banding device for circular culverts provided by this invention can effectively improve the construction quality of mortar banding, ensure that its appearance dimensions meet the drawing requirements, improve work efficiency, and guarantee good waterproof performance of the circular culvert.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0029] like Figures 1 to 6 As shown, the mortar sealing device for a circular pipe culvert provided in this embodiment is used to seal the joint between two pipes of a circular pipe culvert. It includes a support 100 and two arc-shaped clamps 200 connected to the support 100 and arranged opposite to each other. The two arc-shaped clamps 200 can approach each other to fit against the outer wall of the pipe.

[0030] Each arc-shaped clamp 200 includes two spaced-apart stop plates 210. When the arc-shaped clamp 200 is in contact with the outer wall of the pipe, the two stop plates 210 form a mortar grout gap with the outer wall of the pipe.

[0031] In practical use, the mortar application device for circular culverts provided in this embodiment involves bringing the two arc-shaped clamps 200 close together and aligning them with the joints of two adjacent pipes. These clamps are then attached to the outer wall of the pipes, ensuring the joint between the two pipes is positioned between the two stop plates 210. The two stop plates 210 and the outer wall of the joint between the two pipes form a mortar application gap. Finally, the construction worker fills the gap with mortar and smooths it. The mortar application device for circular culverts provided by this invention effectively improves the construction quality of the mortar application, ensures that its dimensions meet the drawing requirements, increases work efficiency, and guarantees good waterproofing performance of the circular culvert.

[0032] Specifically, in this embodiment, the shape of the arc-shaped clamp 200 corresponds to the shape of the outer wall of the pipe. When the two arc-shaped clamps 200 approach each other and abut against the outer wall of the pipe, the two stop plates 210 of the arc-shaped clamp 200 can fully contact the outer wall of the pipe, thereby preventing mortar leakage.

[0033] Considering that most pipes have circular cross-sections, in this preferred embodiment, each arc-shaped clamp 200 is semi-circular, that is, both stop plates 210 are semi-circular structures. When the two arc-shaped clamps 200 approach and connect with each other, they can surround the circumference of the pipe.

[0034] It should be noted that the height of the two stop plates 210, that is, the height along the radial direction of the pipe, is consistent with the thickness of the mortar strip.

[0035] Furthermore, the arc-shaped clamp 200 also includes a connecting plate for connecting the two stop plates 210.

[0036] Preferably, the mortar application device for the circular culvert also includes a driving mechanism. One end of the driving mechanism is connected to the arc-shaped clamp 200, and the other end of the driving mechanism is connected to the bracket 100, which is used to drive the two arc-shaped clamps 200 to move closer or further apart.

[0037] Furthermore, the drive mechanism includes a pull rope 420 and a rotating wheel 410 with a self-locking function.

[0038] The rotating wheel 410 is rotatably connected to the bracket 100. One end of the pull rope 420 is connected to the arc-shaped clamp 200, and the other end of the pull rope 420 is wound around the rotating wheel 410.

[0039] Specifically, in this embodiment, there are two driving mechanisms, each of which is used to drive an arc-shaped clamp 200. Preferably, the driving mechanism includes a rotating wheel 410 and a pull rope 420 wound around the rotating wheel 410. The rotating wheel 410 is rotatably mounted on the bracket 100 and can drive the arc-shaped clamp 200 connected to the pull rope 420 to move by rotating itself, thereby realizing the two arc-shaped clamps 200 moving closer or further apart.

[0040] Preferably, in this embodiment, the rotating wheel 410 is provided with a handle 430 for driving the rotating wheel 410 to rotate. The handle 430 can be manually turned to drive the rotating wheel 410 to rotate. It should be noted that the rotating wheel 410 has a self-locking function. When it is rotated to the correct position, it can automatically lock to prevent it from rotating in the opposite direction, thus preventing the arc-shaped clamp 200 from being unable to maintain its fixed position. The specific structure for realizing the self-locking function can be a ratchet structure or other related structures with a self-locking effect. Those skilled in the art can refer to existing similar structures, which will not be elaborated here.

[0041] It should be noted that the rotating wheel 410 can also be driven by a drive motor, saving manpower and improving efficiency.

[0042] Furthermore, the support 100 includes a horizontally arranged crossbeam 110 and two side beams 120 respectively connected to both ends of the crossbeam 110.

[0043] The mortar application device for the circular culvert also includes a connecting structure, which includes two sliding members 300 that are slidably connected to the crossbeam 110. The end of each sliding member 300 away from the support 100 is connected to an arc-shaped clamp 200. When the driving mechanism drives the two arc-shaped clamps 200, the sliding member 300 can slide along the length direction of the crossbeam 110.

[0044] Preferably, the crossbeam 110 is provided with a "T"-shaped groove 111 extending along its length direction, and the end of the sliding member 300 away from the arc-shaped clamp 200 is provided with a protrusion corresponding to the "T"-shaped groove 111, and the protrusion is slidably connected in the "T"-shaped groove 111.

[0045] It should be noted that the above-mentioned connection structure can also adopt other structural forms, such as the structure of slide rails and slide grooves.

[0046] In this embodiment, the "T"-shaped groove 111 on the crossbeam 110 is only one form exemplified in this embodiment. The groove can also be a dovetail-shaped groove and a protrusion corresponding to the dovetail-shaped groove. There is no limitation here, as long as it can achieve a sliding connection.

[0047] Furthermore, the mortar application device for the circular pipe culvert also includes a clamping structure, which is set between the side beam 120 and the arc-shaped clamp 200 to lock and position the arc-shaped clamp 200 that is attached to the pipe.

[0048] Preferably, the clamping structure includes a clamping member 500, one end of which is hinged to the side beam 120. The clamping member 500 is provided with a plurality of toothed grooves 510, and the arc-shaped clamp 200 is provided with a buckling part 220 corresponding to the toothed grooves 510. The buckling part 220 cooperates with the toothed grooves 510 to fix the arc-shaped clamp 200 attached to the outer wall of the pipe.

[0049] Furthermore, the mortar application device for the circular pipe culvert also includes rollers 140 disposed at the bottom of the support 100, so that the support 100 and the arc-shaped clamp 200 can move.

[0050] Furthermore, the 140 roller is a swivel wheel.

[0051] Specifically, in this embodiment, a fixing plate 130 is connected to the bottom of each side beam 120 of the support 100. The extension direction of the fixing plate 130 is perpendicular to the extension direction of the cross beam 110. There are four casters, with two casters spaced apart on each fixing plate 130. The four casters are arranged in a rectangle so that the entire device can move freely on the two base planes of the circular pipe culvert. After the construction of the joint of two adjacent pipes is completed, it can move along the length direction to carry out the construction of the next joint. The device is very flexible, saves time and effort, and improves construction efficiency.

[0052] In this embodiment, the shape of the arc-shaped clamp plate fits the outer wall of the circular culvert. The width and thickness between the two stop plates 210 of the arc-shaped clamp 200 are consistent with the dimensions of the mortar strip on the drawing. The arc-shaped clamp 200 and the bracket 100 are connected through a connecting structure, a driving mechanism, and a clamping structure. Rollers 140 are provided at the bottom of the bracket 100, which is placed on the concrete base of the circular culvert. In this way, the device can move freely on the circular culvert, which greatly improves the flexibility of use. It saves time and effort during construction and improves work efficiency. The arc-shaped clamp 200 can be opened and closed freely under the combined action of the driving mechanism and the connecting structure. The clamping structure can fix the arc-shaped clamp 200, which is in contact with the outer wall of the pipe, to prevent it from moving. When constructing each mortar strip, the arc-shaped clamp 200 can fit tightly with the outer wall of the circular pipe, ensuring the appearance and construction quality of the mortar strip.

[0053] In summary, the mortar sealing device for circular culverts provided by this invention is used for sealing the joint between two pipes in a circular culvert. It includes a support 100 and two opposing arc-shaped clamps 200 connected to the support 100. The two arc-shaped clamps 200 can approach each other to fit against the outer wall of the pipe. Each arc-shaped clamp 200 includes two spaced-apart stop plates 210. When the arc-shaped clamp 200 fits against the outer wall of the pipe, the two stop plates 210 form a mortar sealing gap with the outer wall of the pipe. In actual use, the two arc-shaped clamps 200 are brought close together and aligned with the joint of two adjacent pipes, then fitted onto the outer wall of the pipe, so that the joint between the two pipes is between the two stop plates 210. The two stop plates 210 form a mortar sealing gap with the outer wall of the joint between the two pipes. Finally, the construction worker fills the mortar sealing gap with mortar and smooths it. The mortar application device for circular pipe culverts provided by this invention can effectively improve the construction quality of mortar application, ensure that its appearance and dimensions meet the requirements of the drawings, improve work efficiency, and ensure good waterproof performance of the circular pipe culvert.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
