Abstract
The utility model discloses a prevent that the tunnel from just propping up the structure and the drainage system of percolating water, prop up a plurality of annular blind pipe and an at least vertical blind pipe in the grid steelframe outside and fix at the inboard a plurality of A -frame of grid steelframe first including fixing the A -frame upper berth is equipped with the flier the drain pipe has been laid in the A -frame, drain pipe and sewage pump connection, the sewage pump sets up in the tunnel sump pit, the annular blind pipe with vertical blind pipe is connected, the play water end (W. E. ) setting of vertical blind pipe is at the face with just between the structure. The utility model discloses an at tunnel pre -buried blind pipe just and between the country rock, in the sump pit of planning in advance in groundwater drainage to the tunnel, rethread sewage pump exhausting to the drain pipe tunnel of discharging prevents that the tunnel from just propping up percolating water, reduces surface subsidence, guarantees tunnel zhi anquan just, improves operation environmental quality and civilized construction level.
Description
Technical field
This utility model is related to a kind of structure for preventing percolating water, and particularly one kind prevents city underground bored tunnel to be located at
The structure and its drainage system of a percolating water at the beginning of water rich strata.
Background technology
Now domestic metro industry is in the ascendant, flourishes in the whole nation one, tier 2 cities, subsurface excavation method as it is a kind of more
The construction method of science, in being verified and being widely used in Subway Tunnel construction in practice.Subsurface excavation method tunnel is more typical
Support form is served as a contrast for first+waterproof+two, is to consider tunnel cost, just props up general with water resistance, then positioned at rich water ground
Easily there is percolating water situation during construction is just in the tunnel of layer, more very just as " Water Curtain Cave ", surface subsidence, construction can be caused
Bad environments, and tunnel just Zhi Zhiliang is endangered, there is potential safety hazard, affect civilized construction in tunnel.
The content of the invention
This utility model provides one kind to solve technical problem present in known technology and prevents a percolating water at the beginning of tunnel
Structure and its drainage system, a percolating water at the beginning of tunnel can be prevented using the structure and its drainage system, reduce surface subsidence, protect
The first Zhi Anquan in card tunnel, improves task environmental quality and civilized construction level.
This utility model is adopted the technical scheme that to solve technical problem present in known technology：One kind prevents tunnel
The structure and its drainage system of a percolating water at the beginning of road, including the multiple annular blind pipe being fixed on the outside of a just grid steel frame and at least
A piece longitudinal blind pipe and the multiple A-frames being fixed on the inside of grid steel frame, are equipped with the A-frame and mark time
Plate, is laid with drain pipe in the A-frame, and the drain pipe is connected with sewage pump, and the sewage pump is arranged on tunnel collection
In puddle, the annular blind pipe is connected with longitudinal blind pipe, and the water side of longitudinal blind pipe is arranged on face and just props up
Between structure.
The annular blind pipe diameter 50mm, is fixed with a just grid steel frame using tied silk I.
Longitudinal blind pipe diameter 80mm, is fixed with a just grid steel frame using tied silk II.
Longitudinal blind pipe and the annular blind pipe are connected using four-way.
The A-frame is formed using 50x50mm square steel pipe weldeds.
This utility model has the advantages and positive effects that：By propping up the pre-buried blind pipe and country rock between at the beginning of tunnel, will
Subsoil water is drained in the catch pit planned in advance in tunnel, then is evacuated to drain pipe discharge tunnel by sewage pump, prevents tunnel
Just a percolating water, reduces surface subsidence, it is ensured that the first Zhi Anquan in tunnel, improves task environmental quality and civilized construction level.

Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinated
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 and Fig. 2, a kind of structure and its drainage system for preventing a percolating water at the beginning of tunnel, including being fixed on just
Prop up the multiple annular blind pipe 1 on the outside of grid steel frame and at least one longitudinal blind pipe 2 and be fixed on multiple on the inside of grid steel frame
A-frame 3, is equipped with step plate 4 on the A-frame 3, and in the A-frame 3 drain pipe 5 is laid with, described
Drain pipe 5 is connected with sewage pump 7, and the sewage pump 7 is arranged in tunnel catch pit 6, and the annular blind pipe 1 is blind with the longitudinal direction
Pipe 2 connects, and the water side of longitudinal blind pipe 2 is arranged on face and just props up between structure.
In the present embodiment, the diameter 50mm of the annular blind pipe 1, is fixed with a just grid steel frame using tied silk I.It is described vertical
To the diameter 80mm of blind pipe 2, fixed using tied silk II with a just grid steel frame.Longitudinal blind pipe 2 and the annular blind pipe 1 are adopted
Four-way connects.The A-frame 3 is formed using 50x50mm square steel pipe weldeds.
Operation principle of the present utility model：
Subsoil water is drained to longitudinal blind pipe 2 by annular blind pipe 1, and subsoil water is drained to tunnel catch pit 6 by longitudinal blind pipe 2
Interior, the water converged in catch pit is drained in the drain pipe 5 by sewage pump 7, and finally discharges tunnel.
Although being described to preferred embodiment of the present utility model above in conjunction with accompanying drawing, this utility model is not
Above-mentioned specific embodiment is confined to, above-mentioned specific embodiment is only schematic, is not restricted, ability
The those of ordinary skill in domain under enlightenment of the present utility model, without departing from this utility model objective and claimed
In the case of scope, many forms can also be made, these are belonged within protection domain of the present utility model.
