After digging stillage truck excavates one section, excavation chassis is exited, then sets up steel pipe scaffold, use little template assembly to construct.Just prop up
Cheng Hou, removes scaffold and template, and excavation chassis advances, and carries out next section of tunnel excavation, circulation construction.Traditional loess tunnel
In road excavation and preliminary bracing work progress, need to repeatedly advance and exit excavation chassis, repeatedly set up support and template, not only efficiency
Low, workload is big, and it is time-consuming long to construct, and after causing excavation, the loess exposed time is long, and landslide easily occurs in vault, increases safety
Hidden danger；The just little template assembly of Zhi Caiyong, seam is many, and casting concrete presentation quality is poor.
Summary of the invention
The purpose of this utility model is for traditional loess tunnel excavation and just props up the defect that mode exists, it is provided that a kind of excavation
And just formwork builds concrete construction combined type chassis, utilize excavation chassis directly to carry out just formwork and build concrete construction, improve construction
Efficiency, reduces potential safety hazard, and improves casting concrete presentation quality.
The technical solution of the utility model is as follows:
A kind of loess tunnel excavation and just formwork build concrete construction combined type chassis, including excavation chassis, described excavation chassis bag
Include two overhead certain altitude, the upper longerons that are horizontally disposed with and are parallel to each other, be horizontally disposed with by many between longeron on two and with
The crossbeam that upper longeron is vertical connects, the two ends of every upper longeron and middle part, and the upper end of the perpendicular support being vertically arranged with many is connected, perpendicular
The middle part of support, is provided with the workbench horizontally outward extended, and the lower end of perpendicular support is connected with horizontally disposed lower longeron, the two of lower longeron
End connects vertical road wheel supporting leg respectively, is provided with road wheel bottom every road wheel supporting leg, and the middle part of lower longeron is vertically arranged two
Root hydraulic lifting supporting leg, it is characterised in that: on described crossbeam, be horizontally disposed with two guide rails parallel with upper longeron, described in lead
Rail is arranged over falsework, and described falsework is arranged over template, and described template includes a backform, and the both sides of backform are respectively
Be articulated and connected the side of a side form, and the opposite side of each side form is hingedly connected mould；Described falsework top is with described
The backform of template is connected by latch, is provided with the roller moved along two guide rails bottom described falsework；Described perpendicular support is provided with
Multiple hydraulically extensible bars, each hydraulically extensible bar one end is connected with described perpendicular support, the other end and the side form of described template or Bian Molian
Connect；Described lower longeron top is provided with HYDRAULIC CONTROL SYSTEM case, and the power line of HYDRAULIC CONTROL SYSTEM case is suspended in a perpendicular support.
This utility model compared with the existing technology, has the advantage that
(1) efficiency of construction is high, and conventional construction method needs after having excavated to exit excavation chassis, then sets up support assembly mould
Plate carries out just formwork and builds concrete construction, and efficiency of construction is low, and cyclic advance short (traditional handicraft every cyclic advance 1.2m), this
Traditional excavation trolley structure is improved by utility model, is lengthened by excavation chassis, and arranges template on excavation chassis, makes
Excavation chassis is integrated with supporting chassis, and in work progress, chassis need not be retreated repeatedly, substantially increases efficiency of construction, and this reality
With cyclic advance every after new application up to 2.0m, often circulation can save for 30 man-hours；
(2) work progress is safer, applies this utility model, can complete formwork and concrete waters after excavation within the shortest time
Build work, greatly reduce loess open-assembly time in atmosphere, decrease hole and push up the probability of appearance of caving in without sign；
(3) this utility model can use bulk integral mold plate, and the seam decreasing traditional approach employing little template assembly generation is many
Defect, concreting presentation quality can be improved.
