Abstract
Waterproof/drainage structure at the bottom of a kind of soft stratum tunnel, to efficiently solve guarded drainage problem at the bottom of soft stratum tunnel, it is to avoid diseases such as rising soil at the bottom of tunnel occur.Including the supporting support plate on floor, tunnel and pile foundation, pile foundation is transversely arranged with tunnel bearing of trend interval, and its top consolidates with support plate, lower end through inverted arch packed layer, secondary lining presses down arch section and preliminary bracing structure enters and stablizes rock-soil layer.Arranging water-swelling rubber water bar between described each pile foundation and inverted arch packed layer, water-swelling rubber water bar was around pile foundation one week.Described tunnel arranges gutter under floor, arranges transverse drainage blind pipe below water-swelling rubber water bar, by subsoil water ejectment to tunnel drainage ditch.
Description
Technical field
This utility model relates to municipal administration and railway tunnel, particularly to waterproof/drainage structure at the bottom of a kind of soft stratum tunnel.
Background technology
, under DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES effect, there is diseases such as rising soil at the bottom of tunnel, tunnel bottom structure is damaged, serious threat in weak surrounding rock
Liner structure and operation security.Along with developing rapidly of China Express Railway, it is actual that ballastless track is widely used in engineering, lays
Tunnel basis settlement after construction value is required high by ballastless track section.At the bottom of conventional tunnel, country rock uses rotary churning pile, injecting grout through steel perforated pipe etc.
Reinforcement measure still can not meet requirement.
The structural shape using railway roadbed supporting structure to separate with tunnel lining structure can efficiently solve tunnel basis sedimentation
Problem, reduces construction investment simultaneously to greatest extent.This structure includes support plate and the pile foundation supporting floor, tunnel, and pile foundation is along horizontal
To and tunnel bearing of trend interval arrange, its top and support plate consolidate, and lower end presses down arch section through inverted arch packed layer, secondary lining
Enter with preliminary bracing structure and stablize rock-soil layer,
Not carrying out guarded drainage process at the bottom of conventional tunnel, weak surrounding rock, under DYNAMIC LOADING OF DRIVING TRAIN ON BRIDGES effect, easily occurs bursting and become muddy when a thaw sets at the bottom of tunnel
Emit the diseases such as mud.
Utility model content
The purpose of this utility model is to provide waterproof/drainage structure at the bottom of a kind of soft stratum tunnel, to efficiently solve soft stratum
Guarded drainage problem at the bottom of tunnel, it is to avoid diseases such as rising soil at the bottom of tunnel occurs.
It is as follows that this utility model solves the technical scheme that this technical problem used:
Waterproof/drainage structure at the bottom of a kind of soft stratum tunnel of the present utility model, including support plate and the stake on supporting floor, tunnel
Base, pile foundation is transversely arranged with tunnel bearing of trend interval, and its top and support plate consolidate, lower end through inverted arch packed layer, two
Secondary lining cutting presses down arch section and preliminary bracing structure enters and stablizes rock-soil layer, it is characterized in that: between described each pile foundation and inverted arch packed layer
Arranging water-swelling rubber water bar, water-swelling rubber water bar was around pile foundation one week;Described tunnel arranges gutter under floor,
Transverse drainage blind pipe is set below water-swelling rubber water bar, by subsoil water ejectment to tunnel drainage ditch.
The beneficial effects of the utility model are, efficiently solve the emission problem of soft stratum subsoil water at the bottom of tunnel, it is to avoid
Diseases such as rising soil at the bottom of tunnel occurs;Simple in construction, easy construction.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is the cross-sectional view of waterproof/drainage structure at the bottom of this utility model a kind of soft stratum tunnel.
Fig. 2 is the plane graph of waterproof/drainage structure at the bottom of this utility model a kind of soft stratum tunnel.
Component name shown in figure and corresponding labelling: secondary lining presses down arch section 11, preliminary bracing structure 12, gutter
13, inverted arch packed layer 14, floor, tunnel 15, pile foundation 20, support plate 21, water-swelling rubber water bar 22, transverse drainage blind pipe
23。
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Seeing figures.1.and.2, waterproof/drainage structure at the bottom of a kind of soft stratum tunnel of the present utility model, including supporting floor, tunnel
The support plate 21 of 15 and pile foundation 20, pile foundation 20 is transversely arranged with tunnel bearing of trend interval, and its top consolidates with support plate 21,
Lower end passes inverted arch packed layer 14, secondary lining presses down arch section 11 and preliminary bracing structure 12 enters and stablizes rock-soil layer.Described each stake
Arranging water-swelling rubber water bar 22 between base 20 and inverted arch packed layer 14, water-swelling rubber water bar 22 is around pile foundation one
Week, at prevention subsurface flow to floor, tunnel 15.Floor, described tunnel arranges gutter 13 15 times, at hydro-expansive rubber sealing
Transverse drainage blind pipe 23 is set below bar 22, by subsoil water ejectment to tunnel drainage ditch 13.Efficiently solve at the bottom of tunnel weak
The emission problem of stratum subsoil water, it is to avoid diseases such as rising soil at the bottom of tunnel occurs;Simple in construction, easy construction.
The above some principle of waterproof/drainage structure at the bottom of this utility model a kind of soft stratum tunnel that simply explain through diagrams,
Shown in being not intended to be confined to this utility model and in described concrete structure and the scope of application, thus every the most sharp
Corresponding amendment and equivalent, belong to the apllied the scope of the claims of this utility model.
