An auxiliary device for filling retaining walls with asphalt-impregnated hemp fiber

Abstract

This utility model discloses an auxiliary device for filling retaining walls with asphalt-impregnated hemp fibers. It includes a handle, with two upright plates symmetrically installed on both sides of the bottom end of the handle. Two extension plates (first extension) are symmetrically arranged on the outer wall of one of the upright plates, and rollers are connected between the extension plates via a rotating shaft. Two extension plates (second extension) are symmetrically arranged on the outer wall of the other upright plate, and an asphalt filling pipe is arranged between the extension plates (second extension) (third extension). The beneficial effects are: This utility model, through the design of the extension plates (first extension), extension plates (second extension), and connecting columns, allows for the installation and fixation of the asphalt filling pipe, rollers, and scraper. When filling the retaining wall joints, the scraper can fill the asphalt-impregnated hemp fibers, allowing them to quickly enter the wall joints.

Combined with the rotation of the rollers, this achieves compaction and leveling of the gaps, realizing three auxiliary functions for gap filling and effectively ensuring the tightness of the wall joint filling.

Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for filling asphalt-impregnated hemp fibers, and specifically to an auxiliary device for filling asphalt-impregnated hemp fibers into retaining walls. Background Technology

[0002] To prevent cracks from forming inside the road retaining wall due to uneven settlement of the foundation, temperature changes, or differences in the bearing capacity of the foundation, expansion joints are generally required for segmented construction, and the waterproofing requirements for the expansion joints at the segmentation points are very high.

[0003] Existing auxiliary devices for filling retaining walls with asphalt-impregnated hemp fibers effectively fill settlement or expansion joints in the retaining wall to achieve its waterproof and debris-proof functions. Although the above method can achieve the filling of asphalt-impregnated hemp fibers by the device, when filling the joints, on-site workers use steel bars or other rods to fill the asphalt-impregnated hemp fibers into the settlement joints little by little. The filling process is slow and cannot be tidied up, resulting in poor compactness of the asphalt-impregnated hemp fibers. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-3 As shown in this embodiment, an auxiliary device for filling a retaining wall with asphalt-impregnated hemp fibers includes a handle 7. Two upright plates 8 are symmetrically installed on both sides of the bottom end of the handle 7. Two extension plates 11 are symmetrically arranged on the outer wall of one upright plate 8, and rollers 9 are connected between the extension plates via a rotating shaft 10. Two extension plates 2 are symmetrically arranged on the outer wall of the other upright plate 8, and an asphalt filling tube 3 is arranged between the extension plates 2. Two slots 4 are symmetrically opened at one end of the asphalt filling tube 3. Insert plates 16 connect the slots 4 to a pull rod 14. Limiting boxes 13 are evenly distributed on the outer wall of the extension plates 2, and compression springs 15 are connected to the limiting boxes 13 around the pull rod 14. Asphalt... On the other side of the filling pipe 3, a caulking pipe 27 is provided. A connecting column 5 is installed at the bottom of the vertical plate 8. The bottom of the connecting column 5 is connected to a scraper 12 through a threaded column 6. Through the design of the extension plate 11, extension plate 2, and connecting column 5, the asphalt filling pipe 3, roller 9, and scraper 12 can be installed and fixed. When filling the gaps of the retaining wall, the scraper 12 can be used to fill the asphalt hemp fibers, allowing them to quickly enter the wall gaps. Then, the asphalt filling pipe 3 will fill the gaps with asphalt. With the rotation of the roller 9, the gaps can be compacted and leveled, realizing the three auxiliary functions of the device for filling gaps and effectively ensuring the tightness of the device's filling of the wall gaps.

[0025] like Figures 1-3 As shown, in this embodiment, the top of the upright plate 8 is connected to a handle 7, and the bottom of the handle 7 is provided with an anti-slip groove 1.

[0026] like Figures 1-3 As shown, in this embodiment, the handle 7 is screwed to the upright plate 8, and the anti-slip groove 1 is formed on the handle 7. The anti-slip groove 1 has a semi-circular arc structure. The design of the handle 7 in conjunction with the anti-slip groove 1 makes it convenient for the user to grip the device.

[0027] like Figures 1-3 As shown, in this embodiment, both extension plate 11 and extension plate 2 are screwed to the upright plate 8, the rotating shaft 10 is rotatably connected to extension plate 11, and the rotating shaft 10 is inserted into the roller 9. The design of the rotating shaft 10 in conjunction with the roller 9 facilitates the rolling and leveling of asphalt.

[0028] like Figures 1-3As shown, in this embodiment, the pull rod 14 is screwed to the insert plate 16, and the insert plate 16 corresponds to the slot 4 one by one. The pull rod 14 pulls the insert plate 16, which compresses the compression spring 15, thereby adjusting the position of the insert plate 16 so that the insert plate 16 can fix the slot 4.

[0029] like Figures 1-3 As shown, in this embodiment, the limiting box 13 is screwed to the extension plate 2, and the two ends of the compression spring 15 are screwed to the insert plate 16 and the limiting box 13 respectively. The limiting box 13 limits the movement position of the insert plate 16.

[0030] like Figures 1-3 As shown in this embodiment, the asphalt filling pipe 3 is connected to the extension plate 2 via a slot, and the joint filling pipe 17 is inserted into the asphalt filling pipe 3. The design of the asphalt filling pipe 3 in conjunction with the joint filling pipe 17 enables uniform asphalt filling into the gap.

[0031] like Figures 1-3 As shown, in this embodiment, the connecting column 5 is screwed to the upright plate 8, the threaded column 6 is threaded to the connecting column 5, and the scraper 12 is screwed to the threaded column 6. The design of the connecting column 5 in conjunction with the threaded column 6 facilitates the installation and use of scrapers 12 of different widths, ensuring the filling effect of the device on asphalt and hemp fibers in different gaps.

[0032] The specific implementation process of this embodiment is as follows: When using the device, asphalt hemp fibers need to be filled into the gaps of the retaining wall. Scrapers 12 of different sizes suitable for entering the gaps are installed on the connecting column 5, so that the scrapers 12 can fill the asphalt hemp fibers evenly in the gaps. Then, the two pull rods 14 are pulled, so that the insert plate 16 can squeeze the compression spring 15, thereby allowing the asphalt filling tube 3 to enter between the two extension plates 2. Then, the pull rods 14 are released, and the compression spring 15 rebounds, so that the insert plate 16 can limit and fix the slot 4. Then, the asphalt filling tube 3 is connected to the asphalt supply equipment, so that the asphalt can be delivered to the filling tube 17. With the movement of the filling tube 17 into the gap, the device can quickly fill the asphalt. Finally, the rollers 9 on the roller shaft 10 can achieve the leveling effect of the device on the asphalt, ensuring the aesthetics of the asphalt hemp fibers during filling.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
