Specific embodiment
Below in conjunction with embodiment, the technical solution of the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only the utility model a part of the embodiment, instead of all the embodiments.Based in the utility model
Embodiment, those skilled in the art's every other embodiment obtained under the premise of not making the creative labor, all belongs to
In the range of the utility model protection.
In order to guarantee that inverted arch construction in tunnel is carried out continuously and tunnel excavation is slagged tap and do not opened by inverted arch with transport of materials in hole
The influence of digging, therefore trestle is set up in inverted arch box cut.
Refering to fig. 1-3, the utility model provides a kind of technical solution:
A kind of simple trestle for tunnel, including two trestle monomers 1, the spacing between trestle should be according to practical passage
Construction machinery conduct and arrange, and the width of trestle monomer 1 should be wider than the tyre width of construction machinery, it is ensured that construction machinery
It is broad by the path of trestle, and then guarantee to be difficult to fall when passing through.
The trestle monomer 1 is welded to form by more I-steel, and the I-steel is HW400 × 400H fashioned iron, the stack
Bridge monomer 1 includes that across section 2 and the climbing section 3 across 1 both ends of section is arranged in, described by beam slab 21 and to be arranged in beam across section 1
The truss structure 22 of 21 bottom of plate forms.Under normal conditions, construction machinery is by the time of trestle probably two seconds or so, i.e. stack
Bridge is especially subjected to the time of construction machinery gravity at two seconds or so across section 2, to ensure the stress safety across section 2, therefore
Truss structure 22 is being added across section 2 in the utility model.
Further, the lower section across section 2 is additionally provided with trestle rack 6, increases the load capacity of trestle with this.
It is ridden on the inverted arch 8 poured across one end of section 2, the other end rides over the other end of inverted arch.
The trestle rack 6 includes rack main body 61, is equipped with hydraulic jacking device 62 in the rack main body 61, and described
61 bottom centre of frame body is equipped with the stroke channel at the jacking end 63 of hydraulic jacking device 62, goes back on 61 bottom of rack main body
It is provided with walk supporting device 64.
The trestle rack 6 is vertically arranged between trestle monomer 1 and the pitted surface of inverted arch pit, the trestle rack 6
Height is less than the spacing between 1 lower end surface of trestle monomer and the pitted surface of inverted arch pit.
The walk supporting device 64 includes at least three idler wheels, at least one in the idler wheel is universal wheel.
The course of work of trestle rack 6 is to be respectively provided with trestle rack 6 under each trestle monomer 1, manually passes through idler wheel for stack
Abutment frame 6 is pushed into 1 lower section of trestle monomer for needing to support, and starts hydraulic jacking device 62, and rack main body 61 is stretched out at jacking end 63
Bottom reaches pitted surface, and then rack main body 61 is lifted up, until the top of rack main body 61 connects with across the lower end surface of section 2
Touching.Because the height of inverted arch pit is different, in the utility model, trestle rack 6 is arranged to liftable structure, is improved
Its adaptability achievees the effect that meet different inverted arch height to support trestle monomer 1.
The beam slab 21 is welded by more I-steel and steel plate, and the truss structure 22 includes that bottom is equipped with crossbeam
23, support 24 is vertically installed in the middle part of crossbeam 23,24 tops of support and 23 both ends of crossbeam are connected with diagonal brace 25.
Above-mentioned truss structure 22 is triangular truss, and further, truss structure 22 can also be parallel truss, parabolic
Line truss etc..
According to the actual situation, in the machinery support at blue railway safety tunnel construction sections, the involved the smallest climbing capacity of machinery
It is 15 °, so, the gradient of the climbing section 3 is 15 °.
Further, checkered plates 4, the checkered plates 4 are provided on the end face of the climbing section 3 and beam slab 21
For more reinforcing bars of transverse weld on the steel plate, and then the non-skid property of trestle is improved, guarantees safety when construction machinery passes through.
Further, described to be provided with multiple lifting lugs 5 on 2 both ends of section, in two end side surfaces of each trestle monomer 1
Two lifting lugs 5 are respectively set, lifting lug 5 is rigid material, i.e., is provided with eight lifting lugs 5 in total on entire trestle, can pass through wirerope
The bucket tooth on lifting lug 5 and digging machine bucket is connected, and then achievees the purpose that movable trestle.
Further, affixed extension board 7 on the left and right side of the trestle, when can effectively prevent construction machinery current
Contained object, which is fallen, influences inverted arch operation.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein
Disclosed form, should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and
Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field
The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all should be in right appended by the utility model
It is required that protection scope in.
