Description
Technical field
It the utility model is related to building structure technology field, more particularly to a kind of additional fixing structure of loess tunnel.
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, but current loess support reinforcement structure and is paid no attention to
Think, however it remains potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of additional fixing structure of loess tunnel, makes the rain on the tunnel top support soil body
Water is along the quick drainage in ditch, it is ensured that and the water in the range of support of tunnel can be excluded quickly, prevent water from penetrating into tunnel top loess,
So as to ensure that safety for tunnel engineering and operation tunnel safety.
To achieve the above object, the utility model provides a kind of additional fixing structure of loess tunnel, and the ruggedized construction includes edge
The straining beam of the loess surface that with massif landforms is adapted laying of the tunnel width direction in tunnel upper, straining beam is in tunnel
Length direction is spacedly distributed, and is above straining beam 40-50cm's on the outside of the straining beam at the both ends in length of tunnel direction
Loess Surface structure, there are gunite concrete structure, gunite concrete knot in the medial surface towards straining beam of Loess Surface structure
Structure is combined closely with straining beam, and the casting concrete knot that thickness is 10cm is connected between every two adjacent straining beams
Structure, the top surface of casting concrete structure and the either flush of straining beam, and casting concrete structure, straining beam and gunite concrete
Structure collectively forms tunnel top gutter, and multiple straining beams being spacedly distributed are provided with along the vertical of length of tunnel direction laying
Binder, vertical binder are spacedly distributed along tunnel width direction, and vertical binder is provided with the equitant position of straining beam stretches into loess
Interior hole, reinforcing bar is provided with hole, the upper end of reinforcing bar is fixedly connected with vertical binder and straining beam, and the lower end of reinforcing bar is fixed on loess
It is interior.
As further improvement of the utility model, reinforcing bar guard member is cased with the reinforcing bar in hole.
Compared with prior art, loess tunnel of the present utility model additional fixing structure has the beneficial effect that：
(1) bolt anchorage is used outside tunnel, the support of anchor pole end uses binder, and the binder tunnel top soil body is set along massif landforms
Put, binder both sides extend out 500mm, make tunnel top support soil body rainwater to be formed along support beam and expansion both sides concrete structure
The quick drainage in ditch, it is ensured that water of the surface water in the range of support of tunnel can be excluded quickly, prevent terrestrial reference water penetrate into tunnel top
Portion's loess, so as to ensure that safety for tunnel engineering and operation tunnel safety.
(2) using reinforcing bar guard member reinforcing bar can be avoided to be contacted with hole inwall, so as to extend the service life of reinforcing bar.
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 elevation of the additional fixing structure of loess tunnel.
Fig. 2 is the plan of the additional fixing structure of loess tunnel.
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. 1-2 is refer to, the additional fixing structure of described loess tunnel is included along the width of tunnel 1 above tunnel 1
The surface of loess 2 laying straining beam 3, straining beam 3 is spacedly distributed in the length direction of tunnel 1, positioned at the length direction of tunnel 1
The outside of the straining beam 3 at both ends is above straining beam 340-50cm Loess Surface structure a, in Loess Surface structure a direction
The medial surface of straining beam 3 has gunite concrete structure 4, and gunite concrete structure 4 is combined closely with straining beam 3, per adjacent two
The casting concrete structure 5 that thickness is 10cm, top surface and the horizontal stroke of casting concrete structure 5 are connected between individual straining beam 3
The either flush of binder 3, and casting concrete structure 5, straining beam 3 collectively form tunnel top row with gunite concrete structure 4
Ditch 6, so as to make the rainwater on the top loess 2 of tunnel 1 along 6 quick drainage of gutter, it is ensured that in the range of the support of tunnel 1
Rainwater can quickly exclude, prevent rainwater penetrate into the top loess of tunnel 1, so as to ensure that the construction safety in tunnel 1 and operation tunnel
Road safety.Multiple straining beams 3 being spacedly distributed be provided with along the length direction of tunnel 1 lay vertical binder 7, indulge binder 7 along
The width of tunnel 1 is spacedly distributed, and vertical binder 7 is provided with the hole 8 stretched into loess 2, hole 8 with 3 equitant position of straining beam
Interior to be provided with reinforcing bar 9, the upper end of reinforcing bar 9 is fixedly connected with vertical binder 7 and straining beam 3, and the lower end of reinforcing bar 9 is fixed in loess 2, is made
It is firm, firm to obtain ruggedized construction.Reinforcing bar guard member 10 is cased with reinforcing bar 9 in hole 8, reinforcing bar can be avoided to be connect with hole inwall
Touch, so as to extend the service life of reinforcing bar.
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.
