Description
Technical field
The utility model belongs to the constructing tunnels such as railway, highway, municipal administration field, more specifically to a kind of tunnel double-lining
Inverted arch construction sump.
Background technique
During current constructing tunnel, in order to guarantee tunnel double-lining construction quality, before constructing tunnel, need pair
Tunnel carries out the first branch blocking construction in just branch back-grouting, tunnel, while in the abutment wall and inverted arch in tunnel before tunnel double-lining construction
Bottom shifts to an earlier date pre-buried blind pipe, it is therefore an objective to outside the ponding discharge tunnel of tunnel double-lining behind, guarantee tunnel double-lining construction quality.If
The water after two backings cannot be discharged in time, the later period will put into a large amount of human and material resources and carry out two lining blocking constructions, and tunnel is applied
Working medium amount and civilized construction will will be greatly reduced.
By the tunnel double-lining construction quality discovery for statistical analysis to having built up, when using above-mentioned construction technology
Afterwards, tunnel double-lining construction causes two lining later period blocking constructions there is also water-stagnating effect after many problems, such as two backings is poor,
Difficulty of construction is big, poor through accuracy, labour's investment is more, loses substantial contribution, while to blind in tunnel double-lining casting process
Tube damage is serious, and live civilized construction is poor, not can guarantee tunnel double-lining back-grouting quality.In order to reduce going out for the above problem
It is existing, while tunnel double-lining construction quality is improved, economic loss caused by reduction is done over again.By experiment and live practice of construction,
Tunnel inverted arch two lining construction in setting sump just can solve and reduce it is above-mentioned lead to the problem of, and two lining inverted arch catchment
Well can be good at using scene waste material, the processing is simple, and high in machining efficiency, site operation speed is fast, construction quality and
Live civilized construction is improved, while also can be reduced later period tunnel double-lining blocking construction, saves economic input.
Summary of the invention
The discharge that inverted arch bottom ponding can be quick, economic when the utility model is constructed mainly for tunnel double-lining, simultaneously
It is further ensured that live civilized construction, guarantees entire tunnel double-lining pouring quality.
To achieve the goals above, the utility model is achieved through the following technical solutions: the tunnel double-lining is faced upward
Arch construction sump includes collector pipe 1, seal plate 2, filter screen 3, cover board 4, two lining concrete 5, inverted arch fill concrete 6, institute
The 1 water inlet side of collector pipe stated is provided with seal plate 2, and the setting of seal plate 2 is in 1 surrounding of collector pipe, the setting of 1 water inlet of collector pipe
There is filter screen 3,1 water outlet of collector pipe is provided with cover board 4, and it is mixed that the water inlet of collector pipe 1 is all arranged in two linings together with seal plate 2
In solidifying soil 5, upper inverted arch fill concrete 6 is covered in the part that collector pipe 1 exposes, only exposes 1 water outlet of collector pipe.
Further, the collector pipe 1 uses Φ 400,6mm steel pipe, and filter screen 3 is used using nylon wire, seal plate 2
4mm seal plate steel plate.
Further, the material that the collector pipe 1 is cut off using open-cut foundation ditch sump, cover board 4 use reinforcing bar square
Plate.
The utility model the utility model has the advantages that
1, tunnel inverted arch two serves as a contrast the application of sump new technology, can be good at the material using scene waste, processing letter
Single, high in machining efficiency, site operation speed is fast, shortens the construction period.
2, in tunnel double-lining casting process, it can use inverted arch underdrain well and focused on, while can be with
Maintenance construction is carried out to tunnel inverted arch and fill concrete using the water in sump, ensure that construction site security civilization ring
Border.
3, the ponding that lining concrete behind can be collected with the sump, provides well for tunnel double-lining back-grouting
Condition guarantees tunnel double-lining back-grouting quality, and then ensure that entire tunnel double-lining waterproof effect and construction quality.
Detailed description of the invention
Fig. 1 sump site operation figure；
Fig. 2 collector pipe front view；
Fig. 3 is collector pipe top view；
In figure, 1- collector pipe, 2- seal plate, 3- filter screen, 4- cover board, 5- bis- serve as a contrast concrete, 6- inverted arch fill concrete.
Specific embodiment
Below in conjunction with the embodiment of the present invention and attached drawing, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
As shown in Figure 1-3, the described tunnel double-lining inverted arch construction sump include collector pipe 1, seal plate 2, filter screen 3,
Cover board 4, two serves as a contrast concrete 5, inverted arch fill concrete 6, and the collector pipe 1 selects 400 steel pipe of Φ, can also use open cut base
The material that hole sump is cut off, and it is processed, after the completion of processing, seal plate 2 is required to weld according to detail design
Steel pipe surrounding is connect, seal plate 2 uses 2 steel plate of 4mm seal plate, and weld seam carries out control by design requirement, through quality and legal periodical inspections
After qualification, it can come into operation.1 water inlet of collector pipe is provided with filter screen 3, and filter screen 3 uses nylon wire, and collector pipe 1 is being pacified
One layer of nylon wire is packaged in the bottom of collector pipe 1 before dress, after collector pipe 1 is installed in place, sump is carried out by two lined steel muscle
It is firm, guarantee sump verticality in inverted arch concreting process, when inverted arch concrete and inverted arch fill concrete 6 have poured
Cheng Hou, the reinforcing bar net cover 4 of one layer of 10 100 × 100mm of Φ in the top cover of collector pipe 1.
Utility model works principle: the easy ponding position in tunnel is marked before being laid with two lining waterproof materials, binds inverted arch reinforcing bar
Collector pipe 1 is mounted on mark position in the process, seal plate 2 can prevent water from infiltrating by the place other than collector pipe 1,
Then casting concrete and backfill inverted arch concrete, 1 well head of collector pipe is concordant with fill concrete face, when tunnel double-lining has been constructed
Cheng Hou can both block sump.
Finally, it is stated that preferred embodiment above is merely to illustrate the technical solution of the utility model, rather than limit to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but it should be understood by those skilled in the art that
Various changes can be made to it in the form and details, without departing from the protection scope of the utility model.
