Description
Technical field
The present invention relates to technical field of tunnel construction, more particularly to a kind of constructing middle partition wall in tunnel template and its construction dress
Put.
Background technology
In Highway Construction in Mountainous Area field, due to being influenceed by landform, landforms, while to ensure technical-economic index and friendship
Logical safety, mainly by setting tunnel to solve the problems, such as route line style.Because constructing tunnel need to be according to arrangement and surrounding rock category
Optimum reasonable construction technique is taken, to ensure duration progress and controlled investment.When length of tunnel reaches certain require, one
As use separate tunnel.When length of tunnel is shorter, preferably using multi-arch type tunnel.
In double-arched tunnel construction of central division wall, template is more important, and its selection directly affects the construction period.Because in tunnel
Pilot tunnel section is smaller, and formwork assembling and disassembling is difficult, influence construction.It is many in the prior art that two kinds of template and assembled formwork are walked using hydraulic pressure certainly
Mode is constructed.
Hydraulic pressure, by walking motor movement certainly, typically there is two kinds of structures from template is walked, and the first is to be provided with two in mid-board side
Bar walking track, template center of gravity vertical line falls within two interorbitals, to maintain homeostasis, template increase additional weight.In the structure
Template is connected in main template body by hydraulic system operation, panel by support bar, and main body is by they sup-port in pilot tunnel side wall
On, be used for construction with cage bar curve partition wall, the structure exist from great, steel using amount it is big, it is costly the shortcomings of；It is for second
Respectively there is a walking track in mid-board both sides, template connects integral by end I-steel, forms homeostasis structure.Should
Template is by hydraulic system operation in structure, and panel is connected in main template body by support bar, and main body is being led by they sup-port
On the wall of hole side, the structure is reduced compared with the first dead load, but still heavier, costly, and the arrangement of reinforcement mid-board that can not construct.
To sum up, hydraulic pressure exists from great, costly from template is walked, and template is difficult in narrow and small middle drift space mounting adjustment.
Assembled formwork generally there are two kinds of structures, and the first is spliced by small-sized punching block, by drawing steel inside template
Muscle is connected, spacer bar fixed form position, outside to ensure template monolithic stability by support or diagonal brace.The template is using artificial peace
It is dress, dismounting, mobile, have the shortcomings that artificial quantity is more, peace is torn cumbersome and time-consuming many and small template open and is easily deformed；Second
It is to be spliced by small-sized punching block, time-division two-step pouring of constructing, wall bottom, which is poured, finishes backfill stone.There is people's number in the structure
Amount is more, time-consuming, the uppity shortcoming of pouring quality.To sum up, to there is installation cumbersome, long in time limit for assembled formwork, in every
Wall operating expenses is high and outward appearance is poor.
Thus, the present inventor relies on experience and the practice for being engaged in relevant industries for many years, proposes a kind of constructing middle partition wall in tunnel
Template and its constructing device, to overcome the defect of prior art.
The content of the invention
It is an object of the invention to provide a kind of constructing middle partition wall in tunnel template and its constructing device, overcome in the prior art
Hydraulic pressure is from the installation that dead load is big, costly, mounting and adjusting is difficult to exist with assembled formwork of walking template presence is cumbersome, the duration
The problems such as long efficiency is low, operating expenses is high, outward appearance is poor, the template and its constructing device can effectively improve construction of central division wall effect
Rate, reduction infrastructure cost and construction cost.
