At present, because the groundwater contains abundant calcium ions or other ions which are easy to form crystals, a large amount of crystals can appear along with the seepage water during tunnel operation in some areas, the crystals are deposited and attached to the surface of a concrete ditch after flocculation and agglomeration, and the solidification and agglomeration are carried out after a period of time, so that water flow space and channels are blocked. Unlike conventional silt deposition, such crystals are firmly attached to the concrete base surface, have high hardness, are difficult to crush, and are not efficient by conventional ditch cleaning methods. In the long term, due to the blockage of the drainage ditch caused by sediments such as crystals at the bottom of the tunnel drainage ditch, water in the tunnel drainage ditch overflows and flows to a road surface or a ballast bed, so that the driving safety is affected.

In view of the above, the designer provides a tunnel drainage ditch, in the service process, the crystallization solidification layer can be broken into small blocks, so that the cleaning is convenient, the cleaning and maintenance workload during tunnel operation is reduced, the tunnel maintenance cost is saved, and the tunnel operation safety is guaranteed.

Referring to fig. 1-4, in the present embodiment, the tunnel drainage ditch includes a drainage ditch body 100 and at least one crystal breaking unit 200. The drainage ditch body 100 is used for being arranged inside the tunnel and located on at least one side of the width direction of the tunnel, and the drainage ditch body 100 is further provided with a drainage groove 130 with a gradient. The at least one breaking unit 200 includes a breaking pad 210 and breaking teeth 220 disposed on the breaking pad 210, and the breaking pad 210 is installed in the drainage channel 130.

It should be appreciated that when designing the tunnel drainage ditch, the drainage ditches can be arranged on two sides of the tunnel interior, and the two drainage ditches are basically arranged in parallel in an extending manner, so that the drainage efficiency can be improved.

In view of the above, the operation principle of the tunnel drainage ditch provided in this embodiment is as follows:

by providing the breaking unit 200 in the drain body 100, when the tunnel water is permeated into the drain body, the crystals carried by the tunnel water are deposited on the breaking pad 210 while flowing through the breaking pad 210. During the solidification of the crystals, intermittent weakened sections are formed in the solidified crystalline layer due to the barrier of the breaking teeth 220. When cleaning, if the amount of the deposited and solidified crystals is not large, the single crystal breaking pad 210 can be directly taken out, and the crystal layer on the surface of the single crystal breaking pad can be poured and cleaned; if the crystals have been deposited and solidified to a certain thickness and hardness, then a spatula may be used to cut the crystalline solid at the location of the breaking teeth 220 along the weakened interface of the crystalline solid, and after removal of the bulk crystalline solid, the monolithic breaking pad 210 is removed and cleaned. By the design, the solidified crystals in the drainage ditch body 100 can be easily broken and quickly cleaned, the cleaning workload of a tunnel drainage system is reduced, and the tunnel maintenance cost is saved and the tunnel operation safety is guaranteed.

The following examples illustrate the detailed construction of the tunnel gutters of the present utility model.

Referring to fig. 2, in this embodiment, alternatively, the drainage ditch is configured with a cross section of U, specifically, the drainage ditch includes a bottom wall 110 and two side walls 120, the two side walls 120 are connected to opposite sides of the bottom wall 110, and the bottom wall 110 and the two side walls 120 cooperate to form a U-shaped drainage ditch body. Also, the bottom wall 110 and the two side walls 120 together define a rectangular drain channel 130. The top surface of the bottom wall 110 constitutes the tank bottom wall 110 of the drain tank 130, and the inner side surfaces of the two side walls 120 constitute the two tank side walls 120 of the drain tank 130. A barrier coating 300 is provided on both the tank bottom wall 110 and both tank side walls 120. The barrier coating 300 may be made of a coating cured layer having hydrophobic properties, in other words, the barrier coating 300 may be provided as a coating cured layer having hydrophobic properties. By providing the barrier coating 300, the in-ditch crystals can be effectively prevented from adhering to the concrete ditch floor. And, isolation coating 300 solidifies on the cell wall of water drainage tank 130, and construction is convenient nimble, and the combination with the cell wall of water drainage tank 130 is firm reliable, is difficult for droing, long service life. The cross section is a plane perpendicular to the extending direction of the drain body 100.

Referring to fig. 2-4, in this embodiment, the breaking unit 200 further includes a baffle 230. Baffle 230 is connected to the breaking pad 210, and after the breaking pad 210 is installed in the drain, the baffle 230 is located on a side of the breaking pad 210 away from the bottom wall 110 of the drain tank 130, that is, the baffle 230 extends in a direction from the bottom to the top of the drain tank 130. Meanwhile, the height of the baffle 230 is lower than the height of the drain groove 130, that is, the upper side edge of the baffle 230 is lower than the plane of the notch of the drain groove 130. Further, the width of the baffle 230 may be the same as the width of the drain tank 130 or smaller than the width of the drain tank 130, and when the breaking unit 200 is installed in the drain tank 130, both sides of the baffle 230 in the width direction of the drain tank 130 may be respectively contacted with the barrier coatings 300 on the two tank sidewalls 120, so that the water blocking effect is good. In addition, during actual service, the baffle 230 is located in front of the water flow direction, so that when the water flows in the water drainage tank 130, the water flow is blocked by the baffle 230, so that crystals are formed on the crystal breaking pad 210 conveniently.

It should be appreciated that the baffle 230 may be welded or adhesively secured to the dummy block 210.

Alternatively, the breaking pad 210 is a rectangular plate, and after the breaking pad 210 is assembled to the drain tank 130, the bottom of the breaking pad 210 contacts with the isolation coating 300 on the tank bottom wall 110 of the drain tank 130, and two sides of the breaking pad 210 contact with the isolation coatings 300 on the two tank side walls 120 of the drain tank 130.

Alternatively, the breaking teeth 220 may have a soft structure, the number of breaking teeth 220 is plural, and the breaking teeth 220 are divided into plural rows, the number of breaking teeth 220 in each row is set as required, and the breaking teeth 220 in each row are uniformly arranged at intervals in the width direction of the drainage channel 130. The plurality of rows of breaking teeth 220 are spaced apart in the length direction of the drainage channel 130.

Referring to fig. 3 or fig. 4, it should be noted that the number of the breaking units 200 may be one or more, and when the number of the breaking units 200 is plural, the breaking units 200 are sequentially spliced in the extending direction of the drainage channel 130. Specifically, the breaking pads 210 of the breaking units 200 are spliced in sequence. When crystals on one or more breaking pads 210 need to be cleaned, the baffle 230 can be directly applied to force, so that the single breaking unit 200 can be detached, and the operation is convenient and flexible.

It should be appreciated that the breaking pads 210 and the breaking teeth 220 may be provided as a unitary structure.

In the tunnel drainage ditch provided in this embodiment, when the water seepage of the tunnel enters the drainage ditch, the crystals carried by the tunnel will be intercepted by the baffle 230 on the broken crystal pad 210 when flowing through the broken crystal pad 210, so as to deposit on the broken crystal pad 210. During the solidification of the crystals, intermittent weakened sections are formed in the solidified crystalline layer due to the barrier of the breaking teeth 220. When cleaning, if the amount of the deposited and solidified crystals is not large, the single crystal breaking pad 210 can be directly taken out from the baffle 230, and the crystal layer on the surface of the single crystal breaking pad is poured and cleaned; if the crystals are deposited and solidified to a certain thickness and hardness, then a tool such as a shovel may be used to cut the crystalline solidification body along the weakened interface of the crystalline solidification body at the position of the breaking teeth 220, and after the bulk crystalline solidification body is taken out, the single piece of breaking pad 210 is taken out for cleaning. Since the side wall 120 and the bottom of the ditch are both coated with the isolation coating 300, crystals and silt are not easy to adhere to the basal surface of the ditch, the residual silt and crystal residues in the ditch can be quickly washed clean by high-pressure water, and then the crystal breaking pad 210 is put back into the ditch. The structure can enable the crystal solidification matters in the drainage ditch to be broken easily and cleaned quickly, reduces the cleaning workload of the tunnel drainage system, and is favorable for saving tunnel maintenance cost and guaranteeing tunnel operation safety.
