Description
Technical field
The invention belongs to the Steel Structural Design in civil engineering industry and manufacturing technology field, and in particular to a kind of overlapping tunnel
Road bracing members；The overlapping tunnel Construction of Supporting being mainly used in subway construction, the support especially suitable for downlink tunnel are protected.
Background technology
In Metro Construction, overlapping tunnel is common construction difficult problem to small spacing up and down.Power in shield-tunneling construction
Learn characteristic, typically take first driving downlink tunnel tunnel the method for uplink tunnel again and constructed.When constructing uplink tunnel, meeting
The periphery soil body and the descending tunnel being molded are had an impact, serious meeting make downlink tunnel produce different degrees of faulting of slab ends and
Leak.Typically hydraulic pressure support is taken to protect downlink tunnel in site operation.
Current hydraulic pressure support chassis is controlled using hydraulic power, multi-point support.This kind of supporting form easily produces branch
Stresses in segments is concentrated at support, so that section of jurisdiction locally produces rupture.Whole equipment manufacture difficulty is big, general small formed steel construction factory
It can not manufacture.In addition it is high, not easy to remove and insufficient to downlink tunnel protection also to there is manufacturing expense in existing hydraulic pressure support chassis
The shortcomings of.
The content of the invention
In order to solve the above-mentioned technical problem, it is an object of the invention to provide a kind of overlapping tunnel bracing members.It is described overlapping
Tunnel bracing members have the characteristics that low cost, easily fabricated and dismounting, and more conventional support of tunnel equipment can be protected bigger in addition
Section of jurisdiction area, it is especially more preferable to bottom section of jurisdiction protecting effect.
To achieve these goals, the technical solution used in the present invention is：
A kind of overlapping tunnel bracing members, it is characterised in that：It is mainly made up of multiple identical support systems and track, more
Individual support system accommodated side-by-side is in orbit；The support system is circular configuration, and bottom is provided with single-wheel edge, and single-wheel edge falls in-orbit
On road；It is fixedly connected between adjacent support system by some connectors；The bottom of a support system is set most on side
There is track lock, the track lock is connected with the support system by a horizontally disposed hydraulic jack, the track locks
It is in orbit to detain fixing lock.
The support system is mainly made up of upper support and lower support, and the upper support and lower support are half
Circular configuration, connected between upper support and lower support by hydraulic jack.
The upper support is mainly made up of the steel superstructure of two identical semicircular structures, described two upper steels
Parallelism structural is arranged symmetrically, and is fixedly connected between each other by multiple longitudinally connected I-steel；
The steel superstructure is from upper steel annulus, the vertical bracing members in top, horizontal to bracing members and oblique bracing members group
Into；The upper steel annulus is the semicircle that forms of steel plate bending, and the both ends of upper steel annulus are respectively with upper level to steel branch
The both ends of support are by being welded and fixed；In upper steel annulus and horizontal to being fixedly connected with two top vertical steel branch between bracing members
Support and two oblique bracing members, for supporting and reinforcing.
The lower support is mainly made up of two identical bottom steel construction Parallel Symmetric arrangements, two bottom steel constructions
Between be fixedly connected by multiple longitudinally connected I-steel；
The bottom steel construction is mainly from bottom steel annulus, the vertical bracing members in bottom, horizontal to bracing members and oblique steel branch
Support composition；The bottom steel annulus is the quadrant arc that steel plate bending forms；The level is led to one end of bracing members
Cross bottom steel annulus and bottom vertical steel supporting welding is to the other end of bracing members into one 90 degree of sector, the level
Symmetrical 90 degree of sector structures therewith；One end of the oblique bracing members is welded on the middle part of bottom steel annulus, other end weldering
It is connected on the horizontal angle to bracing members and the vertical bracing members in bottom.
The lower support is also mobile trolley used including one, and the mobile trolley used level that is located at is to the 90 of bracing members both ends
Spend between sector structure；It is described mobile trolley used mainly by four vertical I-steel, four horizontal I-steel and four longitudinal I-shapeds
The cuboid framework structure that steel is welded, mobile trolley used bottom are provided with four single-wheel edge；The track lock and mobile station
Car is connected by a horizontally disposed hydraulic jack.
The steel superstructure it is horizontal to being symmetrically welded with some limited blocks on bracing members.
The present invention has the advantages that：
（1）The invention provides a kind of new low cost, easily fabricated and dismounting overlapping tunnel support equipment.This is overlapping
Tunnel bracing members are using hydraulic jack as major impetus, using steel structural form.The more conventional support of tunnel of support equipment provided
Equipment can protect bigger section of jurisdiction area, especially more preferable to bottom section of jurisdiction protecting effect（It is thick using 20mm in design, 200mm
Wide circular steel plate round steel sheet protects the upper and lower part of section of jurisdiction respectively；The more conventional hydraulic pressure support form of this design strengthens pair
The protection of bottom section of jurisdiction；Point before instead of with face support supports）；
（2）The present invention uses bracing members as main body stress and supporting construction, 22a I-steel used and M16 high intensity spiral shells
Bolt is easy to get, and it, which is assembled, uses the welding commonly used in steel construction and bolt connection.This new overlapping tunnel bracing members are easy to
Manufacture, low to Manufactures level requirement, required manufacturing time is 8 days, and only stoste pressure supports chassis manufacturing time
27%；Using traditional steel construction, the cost of whole equipment is 300,000, only the 30% of stoste pressure support chassis cost；
（2）In overlapping tunnel construction, can conveniently it be dismantled on the basis of section of jurisdiction is protected, technical difficulty is low.Dismantle speed
It is faster than uplink tunnel driving speed, does not influence uplink tunnel and normally tunnel.
