DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figure 1 Figure 6 The utility model provides technical schemes: a tunnel special high molecular water stop band, including water stop body 1 and install in water stop body 1 middle part lead-through hole 101, water stop body 1 top surface symmetry fixedly connected with water stop rib 102,

[0029] Water stop body 1 side is provided with connecting assembly 2, and connecting assembly 2 includes glue retaining groove 201, and glue retaining groove 201 is arranged on one side of water stop body 1, and extrusion strip 202 is fixedly connected to the other side of water stop body 1, and the side of water stop body 1 where extrusion strip 202 is installed is symmetrically fixedly connected with butt joint block 203, and the side of water stop body 1 where glue retaining groove 201 is arranged is symmetrically provided with inner groove 204;

[0030] Among them, dustproof paste 205 can be pasted to both sides of water stop body 1, glue retaining groove 201 and extrusion strip 202 on different water stop bodies 1 are inserted, and butt joint block 203 and inner groove 204 on different water stop bodies 1 are inserted.

[0031] Among them, the surface of water stop body 1 is symmetrically provided with shaping assembly 3.

[0032] Glue retaining groove 201 is composed of three kinds of grooves, including curved groove arranged at the end of lead-through hole 101, bifurcated groove communicated with the two sides of curved groove and straight groove connected with bifurcated groove, and the contour of extrusion strip 202 is same with glue retaining groove 201, and bifurcated groove and inner groove 204 realize position avoidance.

[0033] Butt joint block 203 is same with water stop body 1 in material, and the shape is barb-shaped.

[0034] ​The dustproof sticker 205 has a relief ring groove 208 in the middle and relief square grooves 207 symmetrically opened on both sides. The mating block 203 can pass through the relief square grooves 207. One end of the dustproof sticker 205 is fixedly connected to a pull ear strap 206. The dustproof sticker 205 is made of polymer material and has wear-resistant and dustproof properties.

[0035] The shaping component 3 includes two pairs of mating sleeves 301, which are symmetrically distributed on both sides of the through hole 101. The mating sleeves 301 are fixedly connected to the surface of the waterstop body 1.

[0036] The top of the connecting sleeve 301 is provided with a roll-up groove 303. The material of the connecting sleeve 301 is the same as that of the waterstop body 1. A shaping rod 302 is inserted between the two connecting sleeves 301 of the same pair. The connecting sleeve 301 can prevent the shaping rod 302 from being misaligned and falling off when it is stuck together.

[0037] The shaping rod 302 is bonded to the outer side of the waterstop body 1. The shaping rod 302 comes in two types: curved rod and straight rod. The various shapes of the shaping rod 302 are more in line with the current situation of curved and straight surfaces in tunnels.

[0038] Working principle: Before using this type of tunnel-specific polymer waterstop, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6 As shown, when it is necessary to join two waterstop bodies 1, firstly, the dustproof stickers 205 on the sides of the two waterstop bodies 1 to be joined are peeled off using the pull tabs 206, thereby exposing the clean joining surfaces of the two waterstop bodies 1, avoiding the need for dust cleaning and saving installation time.

[0039] Then apply glue to the surfaces of the two waterstop strips 1 to be joined. At this time, some glue will naturally remain in the glue groove 201.

[0040] Then, the mating block 203 on one waterstop body 1 is inserted into the inner groove 204 of the other waterstop body 1. Due to the material properties of the mating block 203, the mating block 203 will deform due to compression. After it is completely inserted into the inner groove 204, the deformation disappears and the mating block 203 returns to its original shape and engages with the inner groove 204. During this process, the extrusion strip 202 will squeeze the glue in the glue retention groove 201, thereby directly increasing the contact area between the two waterstop bodies 1 and indirectly increasing the amount of glue, thus increasing the fixing effect.

[0041] When the sealing strip is used on the curved surface and straight line of the tunnel, the shaping rod 302 can be inserted into the inside of the butt joint sleeve 301 by outwardly prying and turning the turning groove 303, so that the glue is applied between the shaping rod 302 and the sealing strip body 1 after the butt joint sleeve 301 is restored, thereby realizing the increase of the external support of the sealing strip body 1, and finally making the sealing strip body 1 more difficult to deform and increasing the sealing effect in long-term use.

[0042] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
