Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel drainage pipe blockage disease prevention and treatment, and specifically relates to a tunnel transverse channel side wall replaceable crystallization precipitation device and method. Background Art

[0002] With the rapid development of my country's transportation industry, the number of tunnels under construction and in operation is increasing, and a series of complex disease problems are constantly emerging. Especially in areas with developed karst and abundant groundwater, tunnel drainage pipes are generally experiencing serious crystallization blockage during the tunnel construction and operation stages. The main component of the white crystals in tunnel drainage pipes is calcium carbonate. The main source of its calcium is the hydration product of cement in concrete, and its carbonate ions mainly come from mineralized ions in groundwater. After chemical reaction, the resulting white crystals adhere to the inner wall of the pipe. If left untreated, the continuous deposition of crystals will eventually cause blockage of the drainage pipe. After the drainage pipe is blocked, it often causes problems such as increased tunnel leakage, arch bottom bulging, and lining blockage, threatening the safety of the tunnel lining structure and increasing maintenance costs. In addition, since the tunnel drainage system is often pre-buried in the lining, it is very difficult to repair after blockage. Therefore, how to solve the problem of crystallization blockage in tunnel drainage pipes is an urgent problem to be solved by technicians in this field.

[0003] The high concentration of calcium and magnesium ions in tunnel groundwater is the primary cause of frequent tunnel crystallization problems. Generally speaking, the higher the calcium and magnesium ion content in groundwater, the higher the groundwater hardness, and the more susceptible tunnel drain pipes are to crystallization blockage. Therefore, reducing the calcium and magnesium ion content in groundwater is key to addressing tunnel crystallization blockage. In recent years, with the advancement of water treatment technology, various water softening measures have emerged. One approach involves adding large amounts of chemicals to the water. These chemicals react with the calcium and magnesium ions in the water, producing a precipitate that can be filtered out to soften the water. Another approach involves ion exchange technology, primarily using sodium cation exchange resins. These resins are typically manufactured as fine, spherical particles with a porous, sponge-like structure. They contain numerous micropores and carry a large number of sodium ions. When raw water passes through the sodium cation exchange resins, the calcium and magnesium ions in the raw water are exchanged for sodium ions, and the ions are retained in the resins. This significantly reduces the calcium and magnesium ion content of the treated raw water, thereby reducing the water hardness. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to illustrate the present invention and are not intended to limit the present invention. The test methods in the following examples, where specific conditions are not specified, are generally carried out under conventional conditions or under conditions recommended by the respective manufacturers.

[0036] refer to Figures 1 to 6 The present invention provides a tunnel transverse channel sidewall replaceable crystallization precipitation device, comprising: a longitudinal water blind pipe 400 and a longitudinal drainage blind pipe 500 buried in the tunnel bottom, and an S-shaped filter module 200 disposed on the tunnel transverse channel sidewall 300. Specifically, the S-shaped filter module 200 is wall-mounted on the tunnel transverse channel sidewall 300. This not only avoids occupying the limited space of the roadway and does not affect driving safety, but also effectively solves the risk of crystallization in the tunnel longitudinal water blind pipe 400 and the longitudinal drainage blind pipe 500, thereby ensuring the safety of the tunnel lining structure.

[0037] In the embodiment of the present invention, the S-shaped filter module 200 includes a first drain pipe 201, a second drain pipe 204 and a plurality of U-shaped drain pipes 202; a hollow support tube 203 with an open surface is respectively provided between the first drain pipe 201 and the U-shaped drain pipe 202, between each two U-shaped drain pipes 202, and between the U-shaped drain pipe 202 and the second drain pipe 204, and a tube cover 2031 matching the hollow support tube 203 is provided on the hollow support tube 203, wherein one side of the tube cover 2031 is connected to the hollow support tube 203 is hinged, so that the hollow carrying cylinder 203 can be opened freely. In addition, a buckle 2031 is provided on the other side of the cylinder cover 2031, and a slot 2033 matching the buckle 2032 is provided on the hollow carrying cylinder 203. The design of the buckle 2032 and the slot 2033 facilitates that when the cylinder cover 2031 is closed, the buckle 2032 on the cylinder cover 2031 is engaged with the slot 2033 on the hollow carrying cylinder 203, so that the cylinder cover 2031 and the hollow carrying cylinder 203 are tightly locked together, thereby improving their stability.

[0038] Furthermore, waterproof pads are provided on the contact surfaces of the hollow supporting tube 203 and the tube cover 2031. The waterproof pads are made of waterproof material. The provision of the waterproof pads improves the sealing performance and prevents the hollow supporting tube 203 from leaking during operation.

[0039] In actual application, there are multiple hollow supporting tubes 203, and the multiple hollow supporting tubes 203 are parallel to each other. A hollow purification tube 206 is embedded in the hollow supporting tube 203. That is to say, the more hollow supporting tubes 203 there are, the more hollow purification tubes 206 there are, and the better the purification effect. The number of hollow supporting tubes 203 is determined by factors such as the length of the tunnel cross-channel side wall 300 and the degree of crystallization of the water flow. It can be increased or decreased according to actual conditions, and the present invention does not make specific limitations here.

[0040] Furthermore, a water stop plate 2061 is provided at each end of the hollow purification cylinder 206. Each water stop plate 2061 has a circular through hole 2062. A filter screen 2063 is provided on the circular through hole 2062. The filter screen 2063 can block larger external impurities and improve the crystallization rate. The inner diameter of the first drain pipe 201, the inner diameter of the U-shaped drain pipe 202, and the inner diameter of the second drain pipe 204 are respectively equal to the inner diameter of the circular through hole 2062.

[0041] Preferably, the inner diameter of the hollow supporting tube 203 is larger than the outer diameter of the first drainage pipe 201, the outer diameter of the U-shaped drainage pipe 202, and the outer diameter of the second drainage pipe 204, in order to compensate for the head loss when the tunnel drainage is filtered and prevent blockage;

[0042] Preferably, the drainage pipes on both sides of the hollow supporting tube 203 should extend into the hollow supporting tube 203 to ensure that the drainage pipes extending into the hollow supporting tube 203 form a water stop head with a certain thickness inside the hollow supporting tube 203, and the drainage pipes located on the left and right sides of the hollow supporting tube 203 should remain parallel to the hollow supporting tube 203 and form a positional relationship with the bottom tangent to the hollow supporting tube 203. In this way, the water in the hollow supporting tube 203 can be discharged in time, and water accumulation in the hollow supporting tube 203 will not occur due to the water outlet position being too high.

[0043] The water inlet end of the first drainage pipe 201 is provided with a water pump 600 and a water inlet switch 2011. The water pump 600 is used to pump water from the lower longitudinal water delivery blind pipe 400 to the higher first drainage pipe 201, the U-shaped drainage pipe 202, and the second drainage pipe 204. The water inlet switch 2011 can control whether water is fed into the first drainage pipe 201. If crystallization of water in the tunnel is to be carried out, the water inlet switch 2011 should be turned on.

[0044] The hollow carrier cylinder 203 is embedded with a hollow purification cylinder 206 with both ends open and matching the interior of the hollow carrier cylinder 203. The interior of the hollow purification cylinder 206 is filled with filter material.

[0045] Furthermore, the filter material is any one of a hard chorion membrane, a sodium type cation exchange resin or a calcium magnesium reaction medicine ball, and the above three filter materials are stored in the hollow purification cylinder 206 respectively to form a hard chorion membrane hollow purification cylinder, a sodium type cation exchange resin hollow purification cylinder and a calcium magnesium reaction medicine ball hollow purification cylinder;

[0046] Furthermore, the hard chorion membrane purification cartridge is formed by a hard chorion membrane tightly attached to the inner wall of the hollow purification cartridge 206. The chorion membrane is made of a hard material and does not swing excessively when water flows through it. This can increase the roughness of the inner wall of the hollow purification cartridge 206, increase the attachment area of ​​the crystals, and improve the crystallization rate.

[0047] Furthermore, the sodium cation exchange resin hollow purification cartridge is enclosed in a sodium cation exchange resin. The porous sponge-like skeleton of the sodium cation exchange resin carries a large amount of sodium ions. When water flows through, the calcium and magnesium ions in the water flow will be exchanged with the sodium ions in the sodium cation exchange resin. The calcium and magnesium ions will be retained in the sodium cation exchange resin, thereby achieving the purpose of reducing the concentration of calcium and magnesium ions in the water flow.

[0048] Furthermore, there are multiple calcium-magnesium reaction balls inside the hollow purification cylinder. The calcium-magnesium reaction balls are small spherical objects made of calcium-magnesium reaction reagents. The calcium-magnesium reaction balls can form multiple water flow channels in the hollow purification cylinder 206. When the water flows through, the calcium-magnesium reaction balls can react with calcium and magnesium ions to generate precipitates. The precipitates will be retained in the hollow purification cylinder 206, and the hardness of the water flow will be greatly reduced.

[0049] In actual application, there are multiple S-shaped filter modules 200, and every two S-shaped filter modules 200 are connected by the second drain pipe 204. The number of S-shaped filter modules 200 can be determined according to factors such as the length of the tunnel transverse channel side wall 300 and the crystallization degree of the water flow. It can be increased or decreased according to actual conditions, and the present invention is not specifically limited here.

[0050] Preferably, there are three S-shaped filter modules 200, wherein the three S-shaped filter modules 200 can be any combination of a hard chorion hollow purification cartridge, a sodium type cation exchange resin hollow purification cartridge, and a calcium-magnesium reaction ball hollow purification cartridge;

[0051] Furthermore, in order to ensure that the tunnel cross-channel side wall replaceable crystallization precipitation device in the present invention can occupy the tunnel cross-channel driving space as little as possible, the S-shaped filter module 200 should be installed as close to the cross-channel side wall 300 as possible, and should be raised to an appropriate height relative to the ground of the tunnel cross-channel so that it can fully occupy the curved side wall space of the tunnel cross-channel, wherein the cross-channel side wall 300 is perpendicular to the length direction of the tunnel main hole 100.

[0052] The water outlet end of the longitudinal water supply blind pipe 400 is connected to the water inlet end of the first drain pipe 201, the first drain pipe 201, the second drain pipe 204 and multiple U-shaped drain pipes 202 are respectively connected to multiple hollow supporting cylinders 203 and face the circular through holes 2062, and the water outlet end of the second drain pipe 204 is connected to the water inlet end of the longitudinal drainage blind pipe 500, wherein the first drain pipe 201, the second drain pipe 204 and multiple U-shaped drain pipes 202 are respectively fixedly connected to multiple hollow supporting cylinders 203.

[0053] The present invention also provides another embodiment, in which the S-shaped filter module 200 further includes a connecting pipe 205, both ends of which are respectively connected to the second drain pipe 204, wherein the connecting pipe 205 serves to provide a confluence outlet in another direction for the water in the second drain pipe 204; a water outlet switch 2051 is provided on the connecting pipe 205, and the water outlet switch 2051 can control whether water is flowing.

[0054] The present invention also provides a tunnel transverse channel side wall replacement type crystallization precipitation method, which is applied to the above tunnel transverse channel side wall replacement type crystallization precipitation device, comprising the following steps:

[0055] Step 1: Select the side wall 300 of the tunnel transverse passage, select an appropriate number and type of S-shaped filter modules 200 according to the crystallization disease situation in the tunnel, select filter materials to be filled in the hollow purification cylinder 206, open the cylinder cover 2031 of the hollow supporting cylinder 203, embed a hollow purification cylinder 203 filled with filter materials in each hollow supporting cylinder 2031, cover the cylinder cover 2031, connect the water outlet end of the longitudinal water delivery blind pipe 400 with the water inlet end of the first drainage pipe 201, the first drainage pipe 201, the second drainage pipe 204 and multiple U-shaped drainage pipes 202 are respectively connected to the multiple hollow supporting cylinders 203 and face the circular through hole 2062, the water outlet end of the second drainage pipe 204 is connected to the water inlet end of the longitudinal drainage blind pipe 500, and the tunnel transverse passage side wall replaceable crystallization precipitation device is installed;

[0056] Step 2: Turn on the water inlet switch 2011 and the water outlet switch 2051, and the tunnel cross channel side wall replaceable crystallization precipitation device starts filtering. After the device has been working for a period of time, the crystals in the hollow purification cylinder 206 will increase and the filtering effect will decrease. At this time, the hollow purification cylinder 206 needs to be replaced. Open the cylinder cover 2031 of the hollow supporting cylinder 203 corresponding to the hollow purification cylinder 206 that needs to be replaced, take out the hollow purification cylinder 206, put in the replaced hollow purification cylinder 206, and cover the cylinder cover 2031.

[0057] For example, there are three S-type filter modules 200. When the three S-type filter modules 200 need to work simultaneously, all the water inlet switches 2011 are turned on and all the water outlet switches 2051 are closed, and the three S-type filter modules 200 can start working simultaneously; when the crystallization disease in the tunnel is relatively light, the number and type of the working S-type filter modules 200 can be appropriately adjusted by opening or closing the water outlet switch 2051 on the connecting pipe.

[0058] Step 3: The staff should check the tunnel cross channel side wall replaceable crystallization precipitation device from time to time. If the filtration effect of the hollow purification cylinder is found to be reduced, repeat step 2.

[0059] The present invention discloses a tunnel transverse channel side wall replaceable crystallization precipitation device and method, which can fully utilize the limited space on the tunnel transverse channel to effectively prevent and control the crystallization blockage disease of the tunnel's longitudinal water supply blind pipe 400 and longitudinal drainage blind pipe 500. The S-shaped filter module 200 is wall-mounted on the tunnel transverse channel side wall 300, which not only avoids occupying the limited space of the roadway and does not affect driving safety, but also effectively solves the crystallization risk of the tunnel's longitudinal water supply blind pipe 400 and longitudinal drainage blind pipe 500, ensuring the safety of the tunnel lining structure. At the same time, the filtering effect of the filter module can be flexibly adjusted according to the different degrees of crystallization disease in the tunnel, thereby reducing the tunnel operation cost.

[0060] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
