Abstract
The utility model discloses a kind of loess tunnel pipe shed support structure, its bow member is made up of I-steel and prefabricated board, prefabricated board is longitudinal and circumferentially disposed along tunnel and is fixed using bolt, one piece of prefabricated board is connected between per two adjacent I-steel, it is inserted with outside bow member at the loess at top along outside tunnel longitudinal direction and ring with the pipe canopy of 3 15 ° of angle arrangements, cement mortar is filled with pipe canopy, a diameter of 70 180mm of pipe canopy, the wall thickness of pipe canopy is 4 10mm, pipe canopy is by long pipe shed, short tube canopy is formed, the length of short tube canopy is 700 1000m, the length of long pipe shed is more than 10m.Loess tunnel pipe shed support structural integrity of the present utility model is good, and single excavation length length, area is big, can effectively solve Canal in Loess Area because water makes soil layer soften and problem of caving in caused by deform, the mechanical shock being effectively isolated in digging process disturbs.
Description
Technical field
It the utility model is related to building structure technology field, more particularly to a kind of loess tunnel pipe shed support structure.
Background technology
The settlement by soaking of loess is a kind of special engineering geological property of loess.Loess has in deadweight or outside loading
Under, structure destroys rapidly the property for occurring to sink suddenly after by water-soaked.Harm of the collapsibility of loess to Human dried bloodstains is non-
Chang great, often damage building, channel, storehouse bank.Therefore, when being built in Collapsible Loess District, to pay special attention to
The infiltration of water is prevented, to ensure safety for tunnel engineering and operation tunnel safety.In the prior art typically using advanced tubule and
The first lining methods that steel arch-shelf hangs Spraying of reinforcement mat with concrete carry out preliminary bracing, it is ensured that work progress construction safety, it is this
The shortcomings that supporting is that supporting scope is small, and insufficient strength, excavation area is small, and water is entrained with during gunite concrete, and loess absorbs
Moisture in concrete easily becomes unstable, the problems such as easily causing landslide.
Utility model content
The purpose of this utility model is to provide a kind of loess tunnel pipe shed support structure, good integrity, single excavation length
Long, area is big, can effectively solve Canal in Loess Area because water soil layer is softened deform caused by cave in problem, be effectively isolated excavation
During mechanical shock interference.
To achieve the above object, the utility model provides a kind of loess tunnel pipe shed support structure, including bow member, the arch
Frame is made up of I-steel and prefabricated board, and prefabricated board is longitudinal and circumferentially disposed along tunnel and is fixed using bolt, per adjacent two
One piece of prefabricated board is connected between I-steel, waterproof adhesive tape, adjacent two pieces of prefabricated boards are additionally provided between prefabricated board and I-steel
Between also be provided with waterproof adhesive tape, be inserted with along outside tunnel longitudinal direction and ring at the loess at top outside bow member and arranged with 3-15 ° of angle
Pipe canopy, be filled with cement mortar in pipe canopy, a diameter of 70-180mm of pipe canopy, the wall thickness of pipe canopy is 4-10mm, adjacent two
Spacing between root pipe canopy is 2-5 times of pipe canopy diameter, and pipe canopy is made up of long pipe shed, short tube canopy, and the length of short tube canopy is 700-
1000m, the length of long pipe shed are more than 10m, and aqueduct is provided with the upper outside of bow member, and aqueduct is through bow member and by along tunnel
The pipeline of road inwall arrangement is connected to the sump in tunnel.
Compared with prior art, loess tunnel pipe shed support structure of the present utility model has the beneficial effect that：
(1) coordinate the bow member being made up of I-steel and prefabricated board using pipe shed support, and use waterproof adhesive tape sealing, so as to
Good integrity, single excavation length length, area is big, can effectively solve Canal in Loess Area because water make soil layer soften and caused by deforming
Landslide problem, the mechanical shock interference being effectively isolated in digging process.
It will be become more fully apparent by following description and with reference to accompanying drawing, the utility model, these accompanying drawings are used to explain this
The embodiment of utility model.
Brief description of the drawings
Fig. 1 is the schematic diagram of loess tunnel pipe shed support structure.
Embodiment
Embodiment of the present utility model described with reference now to accompanying drawing, similar element numbers represent similar member in accompanying drawing
Part.
Fig. 1 is refer to, described loess tunnel pipe shed support structure includes bow member 1, and the bow member 1 is by I-steel 11 and in advance
Making sheet 12 is formed, prefabricated board 12 along tunnel longitudinal direction and circumferentially disposed and fixed using bolt, per two adjacent I-steel 11 it
Between be connected with one piece of prefabricated board 12, waterproof adhesive tape 13, adjacent two pieces of prefabricated boards are additionally provided between prefabricated board 12 and I-steel 11
Waterproof adhesive tape 13 also is provided between 12, for sealing.Be inserted with the loess at the outer top of bow member 1 along outside tunnel longitudinal direction and ring with
The pipe canopy 2 of 3-15 ° of angle arrangement, cement mortar, a diameter of 70-180mm of pipe canopy 2, the wall thickness of pipe canopy 2 are filled with pipe canopy 2
For 4-10mm, the spacing between adjacent two pipe canopies 2 is 2-5 times of the diameter of pipe canopy 2, and pipe canopy 2 is by long pipe shed, short tube canopy structure
Into the length of short tube canopy is 700-1000m, and the length of long pipe shed is more than 10m.Aqueduct 3 is provided with the upper outside of bow member 1,
Aqueduct 3 is connected to the sump in tunnel through bow member 1 and the pipeline 4 by being arranged along tunnel inner wall.
Using above-mentioned supporting construction, good integrity, tunnel single excavation length length is may be such that, area is big, can be effective
Solve Canal in Loess Area because water soil layer is softened and problem of caving in caused by deforming, the mechanical shock being effectively isolated in digging process are done
Disturb.
The utility model is described above in association with most preferred embodiment, but the utility model is not limited to the above and taken off
The embodiment shown, and the various modifications carried out according to essence of the present utility model, equivalent combinations should be covered.
