Description

Integral escape passage for tunnel construction

Technical Field

The utility model belongs to the technical field of the tunnel construction, concretely relates to integral passway for escaping for tunnel construction.

Background

The escape passage is one of five systems which are necessary to be provided with safety measures in tunnel construction. The pipe used in the escape passage can adopt an phi 800 mm socket steel pipe (or an phi 800 mm pressure-resistant corrugated plastic pipe), the length of the pipe sections is 6-8M, the wall thickness is not less than 10mm, the pipe sections can be connected by a sleeve pipe with the diameter larger than 10cm of the escape pipeline, each end is connected by 1M, and the pipe sections are temporarily fixed by a rubber ring or a wood wedge.

In the tunnel construction process, an escape passage must be arranged from the tunnel face to the two linings, and in the prior tunnel construction, because steps exist between the tunnel face and the two linings, the escape pipeline needs to be matched with a switching joint when the steps are passed, so that the method for arranging the escape passage has the following defects: 1. when the step is passed, the pipeline switching part is easy to loosen and separate; people are easy to block at the corner when escaping through the pipeline; 2. the straight pipeline connected through the sleeve is not firm enough, and the pipeline cannot span the foundation pit and cannot be used when the inverted arch foundation pit is excavated; 3. the mouth of pipe sets up in ground, causes the mouth of pipe to block up easily and can't get into when the face excavation.

Disclosure of Invention

Not enough that escape passage exists in to above-mentioned tunnel construction, the utility model provides an integral escape passage for tunnel construction.

The utility model discloses a realize through following technical scheme.

An integrated escape route for tunnel construction, comprising: escape pipes and enclosures;

the enclosure structure consists of an underframe, a side rail and an enclosure at the top; the underframe is of a ladder-shaped structure and consists of two cross rods which are arranged in parallel and a connecting rod A which is fixed between the two cross rods; each cross rod is fixedly provided with the side rail, each side rail consists of an upright rod, a horizontal rod connected with the upright rod and an inclined strut arranged between the adjacent upright rods, and the upright rods are fixed on the cross rods; the top enclosure consists of a plurality of connecting rods B arranged in parallel, and the connecting rods B are fixed between the two side rails; lifting holes are formed in the vertical rods at the two ends of the side rail; the escape pipeline is arranged in the enclosure structure.

Preferably, a reinforcing rib is further arranged at the joint of the vertical rod and the cross rod.

The utility model also discloses another integral escape passage for tunnel construction, which is formed by connecting at least two escape passages; the corrugated elbows are connected at the joints of the two adjacent escape passages and consist of corrugated pipelines and connecting rings connected to the two ends of the corrugated pipelines.

The utility model has simple manufacture and convenient installation; by arranging the enclosure structure outside the escape pipeline, the safety of tunnel construction is effectively improved, and the practicability is high.

Detailed Description

Embodiments of the present invention will now be described with reference to the accompanying drawings, and those skilled in the art will understand that the following embodiments are merely illustrative of the present invention and should not be considered as limiting the scope of the present invention. The specific techniques, connections, conditions, or the like, which are not specified in the examples, are performed according to the techniques, connections, conditions, or the like described in the literature in the art or according to the product specification. The materials, instruments or equipment are not indicated by manufacturers, and all the materials, instruments or equipment are conventional products which can be obtained by purchasing.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "provided" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. To those of ordinary skill in the art, the specific meaning of the above terms in the present invention is understood according to the specific situation.

The first embodiment is as follows:

as shown in fig. 1-4, the utility model provides an integral escape route for tunnel construction, including: an escape pipeline 1 and an enclosure structure 2;

the enclosure structure 2 consists of an underframe 21, a side rail 22 and a top enclosure 23; the underframe 21 is in a ladder-shaped structure and consists of two cross bars 24 which are arranged in parallel and a connecting rod A25 fixed between the two cross bars 24; each cross bar 24 is fixedly provided with the side rail 22, each side rail 22 consists of upright posts 26, horizontal rods 27 connected with the upright posts 26 and inclined struts 28 arranged between the adjacent upright posts 26, and the upright posts 26 are fixed on the cross bars 24; the top enclosure 23 is composed of a plurality of parallel connecting rods B29, the connecting rod B29 is fixed between the two side rails 22; the upright stanchions 26 at the two ends of the side fence 22 are provided with lifting holes 3; the escape pipeline 1 is arranged in the enclosure structure 2; reinforcing ribs 4 are arranged at the joints of the vertical rods 26 and the cross rods 24.

Example two:

further optimize the scheme, the utility model provides an another kind of integral passway for escaping for tunnel construction, it is by three embodiment one the passway for escaping connect and form, the length of passway for escaping can adjust according to actual needs. As shown in fig. 5 and 6, in the case that there are steps between the tunnel face and the second lining, three escape routes according to the first embodiment are required, the second escape route is arranged along the steps, the first and third escape routes are respectively connected with the second escape route, and the connection is connected by using the corrugated elbow of fig. 5.
