Description
Technical field
The present invention relates to Tunnel Engineering technical fields, and in particular to a kind of for the new of Support System in Soft Rock Tunnels leading pre-supporting
Type pipe canopy.
Background technique
Pipe shed method have many advantages, such as construct fast, highly-safe, short time limit, be widely used in mountain tunnel, large span and
In large cross-section tunnel and the poor urban shallow tunnel of geological conditions.Pipe shed method is by squeezing into steel pipe simultaneously into quasi- excavation soil layer
Slip casting, to improve soil layer self-stable ability, stable soil, which encircles and reduces excavation, causes Stratum Loss；Meanwhile steel pipe is formed with country rock
Camber effect can effectively control the deformation of country rock.
It is found in pipe canopy practical application, if the soil body cannot form Load -carring arch or face and not be able to maintain surely between pipe canopy
Fixed, then " the camber effect " of pipe canopy will be unable to work, and is also just unable to reach restrained deformation and protects the effect of environment.In engineering
In practice often by pipe canopy grouting methol guarantee the stabilization of the soil body, but that there may be slip casting effects in the application is bad
Situations such as, therefore the invention patent increases wavy wing plate in two sides, by the wing of pipe canopy by the structure type of change pipe canopy
Plate overlaps two-by-two, then cooperates the cementation of cement grout, promotes the formation of " camber effect ", while reinforcing country rock, pole
The earth improves the integrated carrying ability and water-stagnating effect of pipe canopy.
Summary of the invention
The purpose of the present invention is to provide a kind of anchor pile for slope retaining, one kind is advanced for Support System in Soft Rock Tunnels
The novel pipe shed of pre support when reinforcing weak surrounding rock with pipe canopy, is connected to become pipe canopy using wing plate cooperation cement grout whole
Body improves the bearing capacity and water-stagnating effect of beam-arch structure, inhibits the deformation for not excavating country rock, increases the safety of tunnel excavation
Property, to solve the problems mentioned in the above background technology.In order to reach the above problem.
To achieve the above object, the invention provides the following technical scheme: a kind of be used for Support System in Soft Rock Tunnels leading pre-supporting
Novel threaded pipe canopy, wing plate is arranged in the two sides Guan Peng in including pipe canopy, and the wing plate is in wave structure along pipe canopy radial direction,
The wing plate of adjacent two pipes canopy mutually overlaps, the attached full water mud of the wing plate surrounding after overlap joint, so that pipe canopy is connected to each other as a whole altogether
With carrying；There is slip casting of at least two injected hole for cement grout in pipe canopy spaced set, pipe canopy is squeezed into country rock, pipe canopy
Along the arc-shaped laying of tunnel vault.
Preferably, it is cone structure in the lower end Guan Peng, blade-like screw thread in city is set on its surface, being conducive to the cutting soil body will
Pipe canopy squeezes into country rock and preferably keeps the globality of pipe canopy and reinforce stability.
Preferably, internal screw thread is set on the top Guan Peng.
Preferably, wing plate radial width is 1 to 1.5 times of pipe canopy diameter.
Compared with prior art, the beneficial effects of the present invention are: cooperating slip casting more can be effectively by pipe by increasing wing plate
Canopy is connected to become entirety, improves the total tune of pipe canopy carrying, and playing camber effect can also mention while reinforcing country rock
The water-stagnating effect in senior executive's canopy grouting and reinforcing area；It is poor suitable for mountain tunnel, large span and large cross-section tunnel and geological conditions
Urban shallow tunnel.
Detailed description of the invention
1. the novel pipe shed structural schematic diagram that Fig. 1 is the invention patent.
2. the novel pipe shed left view that Fig. 2 is the invention patent.
3. the novel pipe shed sectional view that Fig. 3 is the invention patent.
Appended drawing reference: 1- wing plate, 2- injected hole, 3- pipe canopy, 4- blade-like screw thread, 5- internal screw thread.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of for the new of Support System in Soft Rock Tunnels leading pre-supporting
Type screwed pipe canopy, as shown in the picture, including pipe canopy 3, wing plate 1 is set in 3 two sides of pipe canopy, the wing plate 1 is along 3 radial direction of pipe canopy
In wave structure, when making novel pipe shed 3 described in wing plate 1 certain radian radially may be present, be conducive between pipe canopy 3
The wing plate 1 of overlap joint, adjacent two pipes canopy 3 mutually overlaps, the attached full water mud of 1 surrounding of wing plate after overlap joint, so that pipe canopy 3 is connected with each other
For whole common carrying；There is slip casting of at least two injected hole 2 for cement grout in 3 spaced set of pipe canopy.
It is wherein cone structure in 3 lower end of pipe canopy, city blade-like screw thread 4 is set on its surface, being conducive to the cutting soil body will
Pipe canopy squeezes into country rock and preferably keeps the globality of pipe canopy and reinforce stability, and internal screw thread 5, the wing is arranged on 3 top of pipe canopy
1 radial width of plate is 1 to 1.5 times of 3 diameter of pipe canopy.
When this novel pipe shed reinforces weak surrounding rock with pipe canopy 3, cooperate cement grout that pipe canopy 3 is connected into using wing plate 1
For entirety, the bearing capacity and water-stagnating effect of beam-arch structure are improved, inhibits the deformation for not excavating country rock, increases the peace of tunnel excavation
Quan Xing.
This novel pipe shed cooperates slip casting more pipe canopy 3 effectively can be connected to become entirety by increasing wing plate 1, improves pipe canopy
The total tune of 3 carryings, the sealing in 3 grouting and reinforcing area of pipe canopy can also be improved while reinforcing country rock by playing camber effect
Effect.
The invention patent city shallow embedding poor suitable for mountain tunnel, large span and large cross-section tunnel and geological conditions
Tunnel.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
