Description
Technical field
The present invention relates 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, destroyed the property for occurring to sink suddenly rapidly by structure after water-soaked.Harm of the collapsibility of loess to Human dried bloodstains is non-
Chang great, often damages 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.
The content of the invention
It is an object of the invention to provide a kind of additional fixing structure of loess tunnel, tunnel top is set to support the rainwater edge on the soil body
The quick drainage in ditch, it is ensured that the water in the range of support of tunnel can be excluded quickly, prevent water from penetrating into tunnel top loess, so that
It ensure that safety for tunnel engineering and operation tunnel safety.
To achieve the above object, the present invention provides a kind of additional fixing structure of loess tunnel, and the ruggedized construction is included along tunnel
Road width is in the straining beam of the loess surface being adapted with the massif landforms laying of tunnel upper, and straining beam is in length of tunnel
Direction is spacedly distributed, and straining beam 40-50cm loess is above on the outside of the straining beam at the two ends in length of tunnel direction
Slope structure, has a gunite concrete structure in the medial surface towards straining beam of Loess Surface structure, gunite concrete structure with
Straining beam is combined closely, and the casting concrete structure that thickness is 10cm is connected between every two adjacent straining beams, is poured
Build the top surface of concrete structure and the either flush of straining beam, and casting concrete structure, straining beam and gunite concrete structure
Tunnel top gutter is collectively formed, multiple straining beams being spacedly distributed are provided with the vertical system laid along length of tunnel direction
Beam, vertical binder is spacedly distributed along tunnel width direction, and vertical binder is provided with the equitant position of straining beam to be stretched into loess
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 in loess.
As a further improvement on the present invention, it is cased with reinforcing bar guard member on the reinforcing bar in hole.
Compared with prior art, loess tunnel of the invention 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.
By following description and with reference to accompanying drawing, the present invention will become more fully apparent, and these accompanying drawings are used to explain the present invention
Embodiment.
Brief description of the drawings
Fig. 1 is the elevation of the additional fixing structure of loess tunnel.

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 two 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 the quick drainage in gutter 6, 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 that ensure that tunnel 1 construction safety 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 the equitant position of straining beam 3
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
Obtain ruggedized construction firm, firm.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.
