Abstract
The utility model discloses a tunnel supporting construction's adjustable work platform, this adjustable work platform is by the platform, braced system and stair are constituteed, the platform includes a middle part platform and two lateral part platforms, braced system includes the stand, platform leg and regulation leg, adjust the leg setting in this adjustable work platform lower part, it is middle porose to adjust the leg, through the fixed altitude mixture control that can realize adjusting the leg of bolt, each slope about the one side of keeping away from the face of this adjustable work platform sets up two sections stair, connect ground and lateral part platform and lateral part platform and middle part platform respectively. This adjustable work platform and the adaptation of tunnel profile phase, top platform are applicable to vault construction work, and the lateral part platform is suitable for both sides haunch position construction work, can be through adjusting packing up and putting down the height of adjusting the platform in order to adapt to the different execution conditions of face in the tunnel of leg to satisfy the normal current of special machines equipment, the commonality is strong.
Description
Technical field
This utility model relates to technical field of construction, particularly relates to the construction used during tunnel support operation
Platform, specifically, is a kind of scalable operation platform for tunnel support work.
Background technology
During constructing tunnel, owing to geological condition can change along with drilling depth, thus affect tunnel excavation
Support types.If running into weak broken wall rock, tunnel face need to reserve a large amount of Core Soil to ensure to open
Dig the safety of supporting construction.In current tunnel support work, generally use a kind of by shaped steel and reinforcing bar
The work platforms in fixed form being welded, but when running into loose wall rock, tunnel face reserves core
During cubsoil, this platform near face, or cannot level steadily cannot be placed after face,
It is difficult to ensure that support work is effectively carried out.And for meeting the current, in this platform of construction equipment
Portion's work surface is higher, causes top construction space narrow, affects being smoothed out of support work.Therefore
Need badly and work platforms is improved, to adapt to the normal construction of different face condition, improve construction
Efficiency.
Utility model content
For the problems referred to above, this utility model provides a kind of scalable construction for tunnel support work
Platform, this scalable operation platform can adapt to the normal construction of different tunnel face condition, improves
Efficiency of construction.
To achieve these goals, this utility model adopts the following technical scheme that
This utility model provides a kind of scalable work platforms for tunnel support construction, this scalable
Work platforms is made up of platform, support system and stair, and platform includes a middle deck and two sides
Portion's platform, support system include column, platform lower limb and 4 regulation lower limbs, 4 regulation lower limb be arranged on this can
Regulation work platforms bottom, this scalable work platforms is tilting to set away from each about the side of face
Put halfpace stair, connect ground and side locating platforms and side locating platforms and middle deck respectively.
Described regulation lower limb is middle porose, by the fixing altitude mixture control that can realize regulating lower limb of latch.
Compared with prior art, this utility model has the beneficial effect that
1, top platform of the present utility model is applicable to tunnel vault construction working, and two side locating platforms are fitted
With haunch position, tunnel both sides construction working, a middle deck and the work of two side locating platforms compositions
Face adapts with tunnel excavation profile, can meet the support work of whole tunnel section.And top construction
Space is big, it is possible to ensure being smoothed out of tunnel support work.
2, use this utility model, can by regulation lower limb pack up and put down regulation platform height,
Plateau levels is made steadily to place, the execution conditions different to adapt to tunnel face, and meet other machines
The normal pass of tool equipment, highly versatile.
In sum, this utility model is simple and practical, conveniently moving, and cost is low, adapts to
Property strong, supporting construction and the normal pass of other construction equipment of varying environment condition in hole can be met.

Reference in figure:
1 middle deck, 2 side locating platforms, 3 stair, 4 regulation lower limbs, 5 latches.
Detailed description of the invention
With reference to Fig. 1 Fig. 3, this utility model provides a kind of scalable work for tunnel support construction
Platform, this scalable work platforms is made up of platform, support system and stair 3, and platform includes one
Middle deck 1 and two side locating platforms 2, middle deck 1 is suitable for the supporting construction of tunnel vault, sidepiece
Platform 2 is suitable for the supporting construction of both sides haunch, the work surface of three platform compositions and tunnel excavation profile
Adapt, the support work of whole section can be met.Support system includes column, platform lower limb and 4
Regulation lower limb 4,4 regulation lower limb 4 is arranged on this scalable work platforms bottom, porose in the middle of regulation lower limb 4,
By the fixing altitude mixture control that can realize regulating lower limb 4 of latch 5.Thus realize work platforms four direction
Altitude mixture control, the execution conditions that tunnel is different can be met.And when constructions such as excavation, explosions with platform
Car moves to beyond safe distance together, conveniently moving.Regulation lower limb 4 can be according to practice of construction feelings in hole
Condition is packed up and is put down, the needs current to adapt to supporting construction and other plant equipment in hole.This is adjustable
Joint work platforms, away from being respectively obliquely installed halfpace stair 3 about the side of face, connects ground respectively
With side locating platforms 2 and side locating platforms 2 and middle deck 1, convenient construction personnel are upper and lower.
During Specific construction, with reference to Fig. 4 Fig. 5, when tunnel face wall rock condition is preferable, without reserved
Core Soil, moves this work platforms to face by elevating conveyor, packs up regulation lower limb 4 and makes podium level
Reduce, flow out enough construction spaces for vault, in order to carry out support work and the blasting boreholes of face
Deng work.When tunnel face wall rock condition is poor have to reserved part Core Soil time, this work mobile
Making platform to face, two regulation lower limbs 4 near face directly rest on reserved Core Soil,
Put down the regulation lower limb 4 away from face, and the position, hole of regulating pin 5 highly makes middle deck 1 with regulation
Approximate horizontal with side locating platforms 2, with convenient construction.When face supporting or boring end-of-job after,
Move this work platforms by loader and recess face, put down all regulation lower limbs 4, raise platform with side
Just other construction equipment passes through.Contrasting former work platforms in fixed form, this utility model can be adjusted flexibly
Joint work platforms anterior and posterior height, to adapt to the construction of face different condition, is ensureing other machine simultaneously
Tool equipment maximum possible can ensure construction space under conditions of passing through smoothly, and the suitability is strong.
