Description

Technical Field

[0001] The utility model relates to the technical field of shield construction, in particular to an auxiliary tool for applying sealing glue to segments for shield construction. Background Art

[0002] Segment is the main assembled component for shield construction and also the innermost barrier of the tunnel. It bears the functions of resisting soil pressure, groundwater pressure and some special loads. It is the permanent lining structure of the shield tunnel. The quality of the segment is directly related to the overall quality and safety of the tunnel, and has a significant impact on the waterproof performance and durability of the tunnel.

[0003] Specifically, during the construction process, the segment not only plays a role in supporting the tunnel wall surface to prevent the tunnel from collapsing due to loose strata, but also effectively prevents water, mud, etc. from entering the tunnel through its characteristics such as high-strength impermeable concrete, thereby ensuring the stability and safety of the tunnel. The segment has a multi-layer sealing structure to achieve high tightness and waterproof performance, and can also reduce internal corrosion and damage of the tunnel and extend the service life of the tunnel.

[0004] At present, from the time the segment leaves the factory to the time it is assembled by the shield machine, it goes through multiple processes to complete the combination of different types of sealing structures with the segment. In this process, currently, manual work is mostly used. A paintbrush or a roller brush is used to evenly apply glue on the segment, and then wait for the glue to dry for a certain period of time, and then the sealing ring (EPDM rubber gasket, water-swellable waterstop strip) and the composite cushion layer (butyl cork pad) can be pasted on the segment. Some problems will be encountered in this process. Since the glue needs to be applied to the segment on-site, tools with bristles cannot be used multiple times. After being used for a certain period of time, they need to be replaced, otherwise the bristles will all be stuck and unable to evenly apply the glue, and the bristles cannot hold the glue. The new brush carries excessive glue, and if it drips naturally or cannot be evenly applied, it will contaminate the segment, resulting in a decrease in the sealing performance of the segment and certain potential safety hazards; using tools without bristles is more difficult to evenly apply the glue into the installation groove of the segment sealing ring, and it is generally placed vertically on the ground; the storage area of the segment is not fixed, and there is no fixed facility to automatically realize this process. Currently, it cannot be separated from workers, but due to personal experience and technical gaps, the quality of this process cannot be well controlled. Currently, the segment sealing layer pasting process completely relies on manual work and disposable tools to complete. The quality of this process depends on the integrity of the tools and the experience of the workers, and will cause problems such as glue waste, segment pollution, site pollution, uneven glue application, and detachment and non-sealing caused by improper installation of the sealing layer, ultimately affecting the quality of shield construction. For this reason, the applicant proposes an auxiliary tool for applying sealing glue to segments for shield construction to solve the above problems. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an auxiliary tool for applying sealing glue to segments based on shield construction, so as to solve the problems put forward in the above-mentioned background technology.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: An auxiliary tool for applying sealing glue to segments based on shield construction, including a glue storage tank, a segment glue applicator gun assembled on the glue storage tank, and a tool for pasting water-swelling waterstop strips;

[0007] A silica gel hose is connected between the segment glue applicator gun and the glue storage tank. A segment glue application roller is assembled inside the segment glue applicator gun, and a glue delivery pipeline corresponding to the segment glue application roller is opened inside the segment glue applicator gun;

[0008] The tool for pasting water-swelling waterstop strips includes a housing. Three rollers are rotatably installed inside the housing. The three rollers are rotatably installed with the housing through roller shafts, and the three rollers are arranged in an L-shaped distribution.

[0009] Preferably, a storage basket is fixedly installed on one side of the glue storage tank, and water-swelling waterstop strips are stored inside the storage basket.

[0010] Preferably, the glue storage tank is a closed pressure-resistant container, and a pressure port is opened at the rear end of the glue storage tank.

[0011] Preferably, a glue outlet communicating with the silica gel hose is opened at the bottom of the glue storage tank. The silica gel hose and the segment glue applicator gun are connected through a glue delivery pipe connector, and the glue delivery pipe connector communicates with the glue delivery pipeline.

[0012] Preferably, a handle is fixedly installed on the outer side of the segment glue applicator gun, and a steel bar groove is opened inside the segment glue application roller.

[0013] Preferably, the segment glue application roller and the segment glue applicator gun are limited and fixed through a magnetic snap buckle, and a magnetic seat cooperating with the magnetic snap buckle is fixedly installed on the segment glue applicator gun.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] At present, the process of pasting the segment sealing layer completely relies on manual labor and disposable tools to complete. The quality of this process depends on the integrity of the tools and the experience of the workers. The auxiliary tool for applying the sealing glue to the segments based on shield tunneling construction provides a set of simple-to-use tool sets for this process, and certain suppression is carried out on the final process quality problems caused by individual differences between workers and equipment. By setting up a special segment glue-applying roller, the cooperation relationship between the roller and the segment enables the roller to evenly apply the glue flowing out of the glue delivery pipeline onto the installation groove of the segment sealing layer, reducing most of the glue waste and solving the problem of uneven glue application. The segment glue-applying roller can perfectly fit the shape of the segment sealing layer pasting groove. Compared with traditional roller brushes and paintbrushes, the excess glue flowing out of the glue delivery pipeline will be squeezed to both sides or the front side, rather than simply dripping under the action of gravity, reducing segment pollution and site pollution. At the same time, the segment glue-applying roller is designed to be replaceable, which can prevent a single roller from being severely contaminated or the glue layer being too thick to complete the set functions, and a new roller can be quickly replaced. The structure is simple and can be reused after simple maintenance or cleaning, reducing cost waste; by setting up a tool for pasting the water-swellable waterstop strip, the two rollers at the rear end can adjust the direction of the water-swellable waterstop strip to prevent the water-swellable waterstop strip from being bent too much when passing through the front roller and unable to be smoothly pushed forward for pasting. Because the tool for pasting the water-swellable waterstop strip uses rollers to paste the water-swellable waterstop strip, the pasting position has higher accuracy compared with the traditional manual calibration.

The various embodiments listed in the present utility model are only used to illustrate the present utility model and are not used to limit the scope of the present utility model. Any obvious modification or change made to the present utility model does not depart from the spirit and scope of the present utility model.

[0025] Please refer to Figures 1-6 As shown, a sealing glue application auxiliary tool based on shield construction segments proposed by the present utility model includes a glue storage tank 9 and a segment glue gun 1 assembled on the glue storage tank 9, as well as a water-swelling waterstop strip pasting tool 13. A silicone hose 16 is connected between the segment glue gun 1 and the glue storage tank 9. A segment glue roller 7 is assembled inside the segment glue gun 1. A glue delivery pipeline 3 corresponding to the segment glue roller 7 is opened inside the segment glue gun 1. The water-swelling waterstop strip pasting tool 13 includes a housing 17. Three rollers 15 are rotatably installed inside the housing 17. The three rollers 15 are rotatably installed with the housing 17 through rollers 14 respectively. The three rollers 15 are arranged in an L-shaped distribution.

[0026] Based on the above-mentioned structural setting, the sealing glue smearing auxiliary tool based on the shield construction pipe segment is composed of a pipe segment glue coating gun 1, a pipe segment glue coating roller 7, a glue storage tank 9 and a water-swellable waterstop strip pasting tool 13, wherein the glue storage tank 9 can be used to conveniently store the glue, and the glue is transported into the pipe segment glue coating gun 1, the pipe segment glue coating roller 7 is aligned on the sealing strip pasting groove of the pipe segment, and the glue is rolled to evenly spread the glue, and the water-swellable waterstop strip is installed on the water-swellable waterstop strip pasting tool 13, and the water-swellable waterstop strip is pushed The water-swellable waterstop sticking tool 13 rolls a circle on the pipe segment to complete the sticking of the water-swellable waterstop. Specifically, in the working process, the pipe segment glue coating roller 7 is assembled by inserting the pipe segment glue coating gun 1 so that the pipe segment glue coating roller 7 can rotate in the pipe segment glue coating gun 1, and the pipe segment glue coating gun 1 is connected to the glue storage tank 9 through the silicone hose 16. By injecting air into the glue storage tank 9 to pressurize it, the increased internal pressure of the glue storage tank 9 will squeeze the glue into the silicone hose 16, and the glue can be supplied to the pipe segment glue coating gun 1. The glue delivery pipe 3 makes the glue adhere to the surface of the pipe segment glue coating roller 7. By aligning the pipe segment glue coating roller 7 on the sealing strip pasting groove of the pipe segment and pushing the pipe segment glue coating roller 7 to roll, the glue can be evenly applied in a circle. The pipe segment glue coating roller 7 can perfectly fit the shape of the sealing layer pasting groove of the pipe segment. The excess glue flowing out of the glue delivery pipe 3 will be squeezed to the sides or the front side by the pipe segment glue coating roller 7. It will not only drip under the action of gravity, but also reduce the pollution of the pipe segment and the site. When the glue dries for a period of time, it will expand when it encounters water. The waterstop strip is installed on the water-swellable waterstop strip pasting tool 13, and the water-swellable waterstop strip is passed through the middle of the two rollers 15 at the rear end, and is wrapped from the upper end of the front roller 15 to the bottom, and the end of the water-swellable waterstop strip that has passed the front roller 15 is pasted on the water-swellable waterstop strip pasting groove, and the water-swellable waterstop strip pasting tool 13 is pushed, and a circle is rolled on the pipe segment to complete the pasting of the water-swellable waterstop strip, and the EPDM rubber sealing pad is put on the pipe segment, and then turned to its pasting groove to complete the installation of the pipe segment sealing layer.

[0027] Furthermore, a storage basket 12 is fixedly mounted on one side of the glue storage tank 9, and a water-swellable waterstop strip is stored inside the storage basket 12. The storage basket 12 can be used to conveniently place the water-swellable waterstop strip to be used, and one end of the water-swellable waterstop strip is extended from the outlet at the rear end of the storage basket 12 and connected to the water-swellable waterstop strip pasting tool (13).

[0028] Furthermore, the glue storage tank 9 is a sealed pressure-resistant container, and a pressurizing port 10 is provided at the rear end of the glue storage tank 9. After injecting glue into the glue storage tank 9, the lid is sealed, and air is pumped into the pressurizing port 10 at the rear end of the glue storage tank 9, and the glue discharge speed is controlled by controlling the internal pressure of the glue storage tank 9.

[0029] Furthermore, a glue outlet 11 communicating with the silicone hose 16 is formed at the bottom of the glue storage tank 9. The silicone hose 16 is connected to the segment gluing gun 1 through a glue delivery pipe connector 5, and the glue delivery pipe connector 5 communicates with the glue delivery pipeline 3. Among them, when the internal pressure of the glue storage tank 9 increases, the glue will be extruded from the glue outlet 11. The glue delivery pipe connector 5 can facilitate the connection with the silicone hose 16, enabling the silicone hose 16 to supply the glue to the segment gluing gun 1.

[0030] Furthermore, a handle 4 is fixedly installed on the outer side of the segment gluing gun 1, and a steel bar groove 8 is formed inside the segment gluing roller 7. Among them, the segment gluing gun 1 can be operated for gluing by holding the handle 4, and the steel bar groove 8 is used for subsequent structural reinforcement of the segment gluing roller 7.

[0031] Furthermore, the segment gluing roller 7 is limited and fixed to the segment gluing gun 1 through a magnetic snap 2, and a magnetic seat 6 cooperating with the magnetic snap 2 is fixedly installed on the segment gluing gun 1. Among them, the segment gluing roller 7 can be directly inserted into the chamfered circular through hole of the segment gluing gun 1, and the other end is adsorbed and fixed by the magnetic seat 6 and the magnetic snap 2. This can not affect the normal rolling of the segment gluing roller 7, and can also achieve rapid replacement of the segment gluing roller 7. The segment gluing roller 7 can be reused through simple maintenance or cleaning, reducing cost waste.
