Detailed Description
Referring to fig. 1-4, a tunnel trash separation drain meeting high environmental requirements includes a plurality of first prefabricated members 10 and second prefabricated members 2, and a plurality of first cover plates 3 and second cover plates 1. The first prefabricated member 10 is the U type, and a plurality of first prefabricated members 10 vertically splice along the tunnel and form the sewage underdrain for the sewage in the drainage tunnel, the slope of sewage underdrain is unanimous with the tunnel longitudinal slope. The second prefab 2 is the L type, and a plurality of second prefabs 2 form the cable pit along behind the vertical concatenation in tunnel and between the tunnel lining structure for the cable conductor of arranging. Clear water underdrains are formed between the left side wall of the first prefabricated member 10 and the side wall of the second prefabricated member 2 and the tunnel lining structure, namely, one side wall of the clear water underdrains is shared by the sewage underdrains, the upper portion of the other side wall is shared by the cable trench, the lower portion and the bottom of the other side wall are shared by the tunnel lining structure, and the clear water underdrains are communicated with the longitudinal drain pipes 5 through the plurality of transverse water guide pipes 6 and used for guiding and draining the underground water collected through the longitudinal drain pipes 5.
First apron 3 vertically sets gradually on sewage underdrain and clear water underdrain along the tunnel, sewage underdrain and clear water underdrain share apron promptly, 3 both ends of first apron support respectively on second prefab 3 and first prefab 10, first apron 3 is located sewage underdrain top department and is equipped with arc and cuts the water recess, the bottom of arc cut the water recess vertically evenly is equipped with a plurality of outlet 11 along the tunnel, sewage in the tunnel collects to arc and cuts the water recess in to introduce the sewage underdrain through outlet 11. Preferably, the distance between adjacent drainage holes 11 is 10 cm. The second cover plate 1 is sequentially arranged on the cable trench along the longitudinal direction of the tunnel, and two ends of the second cover plate 1 are respectively supported on the tunnel lining structure and the second prefabricated member 2.
Among the above-mentioned technical scheme, its tunnel that satisfies high environmental requirement separates escape canal of decontaminating can satisfy the requirement of the separation of decontaminating of tunnel construction and operation stage, especially to the very big extra-long and overlength tunnel construction of sewage volume, carries out purification treatment after the sewage of discharging alone, and water after the purification can reuse, satisfies high environmental requirement. Most structures of the drainage ditch all adopt a prefabricated form, so that the construction difficulty is reduced, the construction efficiency is improved, and during maintenance, the side type drainage ditch does not need to break the pavement 4, so that the maintenance is convenient.
The novel clean water drainage structure is characterized by further comprising a plurality of middle cover plates 8, trapezoidal protrusions are arranged on the outer wall of the left side of the first prefabricated part 9, two ends of each middle cover plate 8 are respectively placed on the tunnel lining structure and the corresponding trapezoidal protrusions, the middle cover plates 8 are sequentially arranged along the longitudinal direction of the clean water blind ditches and divide the clean water blind ditches into an upper heat preservation area and a lower overflowing area, heat preservation materials 7 are filled in the heat preservation areas, and the joints of the clean water blind ditches and the transverse water guide pipes 6 are located in the overflowing areas. The clear water blind ditch for leading and draining the underground water is subjected to heat preservation treatment by the mode, so that the anti-freezing requirement of the alpine region is met. In the non-heat-preservation tunnel section, the heat-preservation area and the corresponding middle cover plate 8 can be eliminated, and at the moment, the whole clear water underdrain is used as a water passing section.
The height of the left side wall of the first prefabricated member 10 is smaller than that of the right side wall of the first prefabricated member, so that the acting points of the first cover plate 3 are distributed to two ends, and the stability of the support of the first cover plate 3 is ensured.
The width of the right side wall of the first preform 10 is greater than that of the left side wall thereof and the width of the upper half of the right side wall is greater than that of the lower half thereof. That is, the side wall of the sewage underdrain close to the road surface 4 is wide and the upper part is enlarged, the enlarged end is the first cover plate 3 and the bearing platform of the road surface 4, the size of the enlarged end can be adjusted properly, but the width of the lower non-enlarged end is not less than 10cm to ensure that the side wall of the sewage underdrain close to the road surface 4 is not damaged by the pressure of the road surface 4. Preferably, a waterproof cement mortar mat is laid as a finishing layer 9 under the first preform 10.
The tunnel left and right sides all sets up the escape canal, and the concrete size of left and right sides escape canal is confirmed according to construction and operation needs to consider the influence of 4 cross slopes on road surface, the size of left and right sides escape canal can have the difference, but the form keeps unanimous.
Specifically, during tunnel construction, the escape canal is opened, but clear water underdrain covers middle apron 8, does not fill insulation material 7, and during construction, face construction sewage and face basement rock crack water discharge in time to the sewage underdrain, and during tunnel operation, first apron 10 and middle apron 8 are all covered, and groundwater is discharged into the clear water underdrain through horizontal aqueduct 6, and sewage converges into the sewage underdrain from outlet 11 to realize the separation of decontaminating.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
