Description

Technical Field

[0001] This utility model relates to the field of tunnel sidewall water-stopping technology, and in particular to an environmentally friendly tunnel sidewall water-stopping structure. Background Technology

[0002] Tunnel sidewall waterstopping mainly involves installing waterstops or strips at construction joints and expansion joints, as well as a drainage system within the tunnel, to prevent groundwater seepage and leakage. Therefore, an environmentally friendly tunnel sidewall waterstopping structure, published under CN213478355U, involves pre-embedding connecting cylinders within the tunnel sidewall during construction. After completing a section of the sidewall, the waterstop is inserted and filled into the construction joint. The support rod is then connected to the connecting cylinder using bolts. Finally, following the sequence of positioning nut - tightening inner rod - positioning nut - fixing inner rod - positioning nut, the positioning nut, and the inner rod are secured. The inner rod is fixed and connected to the support rod. The position of the positioning nut is adjusted according to the length of the next section of the tunnel sidewall to be poured. The outer tube is rotated so that the fixing plate abuts against the waterstop extending along the construction joint. Then the outer tube is rotated to move the clamping plate closer to the waterstop until the waterstop is pressed against the fixing plate. Then the next section of the tunnel sidewall is poured. After the pouring is completed, the bolts are loosened to separate the support rod from the connecting tube. During the concrete pouring and vibration process, the clamping assembly plays a role in positioning and fixing the waterstop, reducing the probability of the waterstop moving during the concrete pouring and vibration process.

[0003] However, the environmentally friendly tunnel sidewall waterstop structure uses support rods to assist in fixing the waterstop. If the waterstop laying route is tortuous, the rigid support rods may not be able to adapt to this change, causing the waterstop to not fit tightly against the construction joint and affecting the waterstop effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an environmentally friendly tunnel sidewall water-stopping structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly tunnel sidewall water-stop structure, including a water-stop strip and several fixed seats arranged along the laying path of the water-stop strip. Worm gears are rotatably connected to the top edges of both sides of the fixed seats. Two worm gears are coaxially distributed and each of the two worm gears has a rail fixedly installed at one end facing each other. A bracket is movably installed above the fixed seats and is inserted into the two rails. An abutment frame is hinged to the top edge of one side of the bracket. An abutment roller is rotatably connected inside the abutment frame and is arranged along the width direction of the water-stop strip for rolling connection with the surface of the water-stop strip. Bolts are threadedly connected to the top edge of the other side of the bracket at the hinge position of the abutment frame. The shank of the two bolts is spherical and abuts against the upper and lower ends of one side of the abutment frame, respectively.

[0006] Preferably, the fixing seat is detachably connected to the inner wall of the tunnel.

[0007] Preferably, the insertion rails are distributed along the diameter direction of the worm gear, and several positioning holes distributed from top to bottom are provided on both sides of the insertion bracket. Inserts that are inserted into the positioning holes are provided through the insertion rails.

[0008] Preferably, two worm gears are rotatably connected to both sides of the upper surface of the fixed base. The two worm gears are distributed in parallel and are respectively engaged with two worm wheels.

[0009] Preferably, one end of each of the two worm gears passes through the surface of the fixed seat, and a sprocket is fixedly installed at the through end of the worm gear, and a chain is meshed between the two sprockets.

[0010] Preferably, two stop bars are symmetrically fixedly installed on the side of the abutment frame, and the opposite sides of the two stop bars are slidably connected to the spherical part of the bolt rod.

[0011] Preferably, an overlap piece is fixedly installed on the bottom edge of the abutment frame, and the overlap piece is used to overlap with the bottom edge of the waterstop.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a fixed seat, several independent fixed seats are set along the laying path of the waterstop. By adjusting the height and inclination of the insert relative to the fixed seat, the height of the abutment can be adjusted according to the height of the waterstop. The abutment rollers on the abutment are used to press the waterstop to fix it, thus ensuring the sealing effect.

[0014] 2. In this utility model, by rotating the two bolts on the insert bracket respectively, the contact bracket can be forced to be parallel to the width direction of the waterstop under the blocking action of the two stop bars, and the contact roller installed inside it can press against the surface of the waterstop. Furthermore, the contact roller rolls to facilitate the tightening of the waterstop by the personnel, and the contact roller rolls accordingly, without generating friction between it and the waterstop.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, an environmentally friendly tunnel sidewall water-stop structure includes a waterstop 1 and several fixing seats 2 arranged along the laying path of the waterstop 1. The fixing seats 2 are detachably connected to the inner wall of the tunnel and are fixed to the inner wall of the tunnel using expansion bolts or other known technologies or means. Worm gears 11 are rotatably connected to the top edges on both sides of the fixing seats 2. Two worms 9 are rotatably connected to both sides of the upper surface of the fixing seats 2. The two worms 9 are parallel and mesh with the two worm gears 11 respectively. One end of each worm 9 passes through the surface of the fixing seat 2 and a sprocket 12 is fixedly installed at the through end of the worm 9. A chain 13 meshes between the two sprockets 12. By connecting the two sprockets 12 with the chain 13, the two sprockets 12 can be rotated at the same speed, thereby enabling the worms 9 connected to the two sprockets 12 to rotate at the same speed. The meshing connection between the worms 9 and the worm gears 11 enables the two worm gears 11 to rotate at the same speed.

[0023] Two worm gears 11 are coaxially distributed, and each of the two worm gears 11 is fixedly mounted with a rail 14 at one end facing each other. A bracket 5 that is movably mounted above the fixed base 2 is inserted into the two rails 14. The rails 14 are distributed along the diameter of the worm gears 11. Several positioning holes 15 distributed from top to bottom are opened on both sides of the bracket 5. Inserts 10 that are inserted into the positioning holes 15 are provided through the rails 14. By rotating the two worm gears 11 at the same speed, the two rails 14 are rotated at the same speed while maintaining a relatively parallel arrangement, thus adjusting the tilt of the bracket 5 inserted into the rails 14. Furthermore, by inserting the inserts 10 into the rails 14 and passing them through the positioning holes 15 at different positions on the bracket 5, the height of the bracket 5 can be adjusted. In addition, the inserts 10 used in this solution are magnetically attracted to the rails 14.

[0024] A contact frame 3 is hinged to the top edge of one side of the insert 5. A contact roller 4, rotatably connected within the contact frame 3 and positioned along the width of the waterstop 1, is used for rolling contact with the surface of the waterstop 1. Bolts 6 are threaded onto the top edge of the other side of the insert 5 at both the upper and lower positions of the hinge point of the contact frame 3. The shanks of the two bolts 6 are spherical and abut against the upper and lower ends of one side of the contact frame 3, respectively. Two stop bars 7 are symmetrically fixed to the side of the contact frame 3. The opposite sides of the two stop bars 7 are slidably connected to the spherical portions of the bolt 6 shanks. The bottom edge of the contact frame 3 is fixedly mounted... Equipped with a lap plate 8, which overlaps with the bottom edge of the waterstop 1, it can prevent the waterstop 1 from swaying up and down. After the height and tilt of the insert 5 are adjusted, by rotating the two bolts 6 on the insert 5 respectively, the abutment frame 3 can be forced to be parallel to the width direction of the waterstop 1 under the blocking action of the two stop bars 7, and the abutment roller 4 installed inside it can press against the surface of the waterstop 1. Furthermore, the abutment roller 4 rolls to facilitate the tightening of the waterstop 1 by personnel. The abutment roller 4 rolls accordingly and will not rub against the waterstop 1.

[0025] Working principle: After the waterstop 1 is laid, the fixing seat 2 is installed along the laying direction of the waterstop 1. The inclination of the insertion rail 14 is adjusted by rotating the drive worm gear 11, thereby adjusting the inclination of the insertion bracket 5. Then, the height of the insertion bracket 5 is adjusted by the plug 10. According to the inclination of the waterstop 1, the two bolts 6 on the insertion bracket 5 are rotated respectively. Under the blocking action of the two stop bars 7, the contact frame 3 is forced to be parallel to the width direction of the waterstop 1. The contact roller 4 installed inside it presses against the surface of the waterstop 1. Furthermore, the contact roller 4 rolls to facilitate the tightening of the waterstop 1 by personnel. The contact roller 4 rolls with it and will not generate friction with the waterstop 1.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
