Abstract
The utility model discloses a novel tunnel structure, hang including the tunnel body, be located the tunnel body outside and detain the side slope and collapse the landslide body that links to each other with hanging the side slope of detaining, the side slope is provided with a plurality of grout pipes in collapsing the landslide body, through grout pipe grout back in the side slope collapse the landslide in form a plurality of layers of grout back up coat, grout pipe outer end still is provided with grout pipe extension, and grout pipe extension is located the tunnel portal front formation construction safety protection canopy, a plurality of grout holes have evenly been arranged on the grout pipe. The utility model discloses a squeeze into the grout pipe in the safe construction district of side slope, carry out preliminary anchor to the side slope, then grout to the side slope through the grout pipe, form the back up coat, then carry out side slope reinforcement and tunnel excavation construction under the protection of the construction safety canopy that the section formed prolongs life at the grout pipe. The workload of the landslide treatment of the hanging opening side slope is simplified, the adaptability of the tunnel hanging opening construction to geological conditions is improved, and the construction safety is improved.
Description
Technical field
The utility model belongs to tunnel structure design field, specifically relates to a kind of novel tunnel structure.
Background technology
Tunnel engineering is widely used in the industry such as traffic, the energy of China, and its construction operation is complicated, especially in mouth hanging section, often because geological conditions does not meet requirement of strength, for reducing tunnel excavation and lining project amount, the reduction of erection time, there is various tunnel structure at present.As the publication number Chinese patent that is CN 203546685 U discloses a kind of tunnel structure of optimization, it comprises portal, barrel and is arranged on barrel mouth hanging position and the reinforced concrete soil cave body straight line ennation of connection portal and barrel, barrel be provided with tunnel mouth hanging side slope and originate in tunnel mouth hanging side slope, reinforced concrete soil cave body straight line ennation is provided with transitional seams with the junction of portal and barrel respectively, is provided with sealing in transitional seams.This technical scheme is the straightway extending tunnel bend head and the tail by arranging tunnel extension at mouth hanging place, to meet code requirement, avoid to new hole line from newly carrying out geological prospecting analysis, thus minimizing tunnel digs, lining project amount, to shorten the construction period, to save construction investment.But owing to needing to carry out large-scale side slope grouting, excavation and supporting during tunnel construction, therefore to mouth hanging position choose and hole line choose formed restriction.Once mouth hanging construction, domatic slumping unstability occurs and often cause comparatively large-engineering loss, except amendment hole line is from new mouth hanging, also cause casualties, the process of unstability face is also very difficult; Not only increase Construction Technology difficulty, too increase investment, great potential safety hazard is caused to the safety of constructor.
Utility model content
For solving the problem, the utility model provides a kind of novel tunnel structure.Thus reduce tunnel mouth hanging Geological Condition Requirement, reduce difficulty of construction and input, available protecting constructor's safety, shortens the construction period, cost saving.
The utility model is achieved by following technical solution.
A kind of novel tunnel structure; comprise tunnel body, be positioned at outside tunnel body buckle side slope and with the side slope rockfall landslide buckling side slope and be connected; some grout pipes are provided with in described side slope rockfall landslide; in side slope rockfall landslide, some layers of consolidation by grouting layer are formed after being in the milk by grout pipe; described grout pipe outer end is also provided with grout pipe extension, and grout pipe extension be positioned at tunnel formed in front of the door construction safety protection canopy.
Described grout pipe some grout holes have been evenly arranged.
Described grout pipe adopts floral tube or steel pipe to make, and its end first entering rock is taper.
Described consolidation by grouting layer completes the rear induration forming slurries and geologic body of grouting for utilizing grout pipe.
Safe construction section reserved when described grout pipe extension is construction grouting pipe.
The beneficial effects of the utility model are:
Compared with prior art: the utility model is by when particularly mouth hanging collapses at mouth hanging place; grout pipe is squeezed in the safe construction district of side slope; preliminary anchoring is carried out to side slope; then by grout pipe, side slope is in the milk; form back-up coat, then prolong the protection of the construction safety canopy that raw section is formed at grout pipe under, carry out slope reinforcement and Tunnel excavation.Simplify the workload of mouth hanging side slope slumping process, add the compliance of tunnel mouth hanging construction to geological conditions, add working security, shorten the construction period, save construction investment, there is significant economic benefit and good compliance.
Accompanying drawing explanation
Fig. 1 is section structure schematic diagram of the present utility model;
Fig. 2 is the A-A direction view of Fig. 1;
Fig. 3 is the structural representation of grout pipe in the utility model.
In figure: 1-tunnel body, 2-mouth hanging side slope, 3-side slope rockfall landslide, 4-consolidation by grouting layer, 5-grout pipe, 6-grout hole, 7-grout pipe extension.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, Figure 2, Figure 3 shows; the novel tunnel structure of one described in the utility model; comprise tunnel body 1, be positioned at outside tunnel body 1 buckle side slope 2 and with the side slope rockfall landslide 3 buckling side slope 2 and be connected; some grout pipes 5 are provided with in described side slope rockfall landslide 3; in side slope rockfall landslide 3, some layers of consolidation by grouting layer 4 are formed after being in the milk by grout pipe 5; described grout pipe 5 outer end is also provided with grout pipe extension 7, and grout pipe extension 7 be positioned at tunnel formed in front of the door construction safety protection canopy.The technical program squeezes into grout pipe by the safe construction district in side slope; preliminary anchoring is carried out to side slope; then by grout pipe, side slope is in the milk, forms back-up coat, then prolong the protection of the construction safety canopy that raw section is formed at grout pipe under, carry out slope reinforcement and Tunnel excavation.Simplify the workload of mouth hanging side slope slumping process, add the compliance of tunnel mouth hanging construction to geological conditions, add working security, shorten the construction period, save construction investment.
Described grout pipe 5 some grout holes 6 have been evenly arranged.
Described grout pipe 5 adopts floral tube or steel pipe to make, and its end first entering rock is taper, and namely the other end of floral tube or steel pipe is taper.In reality processing, grout pipe 5 can be processed with any steel pipe.
Described consolidation by grouting layer 4 completes the rear induration forming slurries and geologic body of grouting for utilizing grout pipe 5.
Safe construction section reserved when described grout pipe extension 7 is construction grouting pipe 5.It can be utilized as the basis of other safety prevention measures.
Above-mentioned tunnel 1 can be the tunnel of arbitrary form and purposes.
Above-mentioned mouth hanging side slope 2 can be any side slope type.
Above-mentioned side slope rockfall landslide 3 can be the rockfall landslide of arbitrary form.
