Description
Technical field
The utility model relates to inclined shaft and enters positive hole applied technical field, and especially a kind of inclined shaft enters Zheng Dong and to caunch structure.
Background technology
Along with the fast development of infrastructure construction, inclined shaft enters Zheng Dong and caunches as with its strong adaptability, bearing capacity is high, features such as easy construction and be widely used in culvert, the building engineering fields such as railway tunnel, caunch belong to concealed work because inclined shaft enters Zheng Dong, in practice of construction, affect its construction quality many factors and wayward, technology of caunching is perfect not, its quality can not be guaranteed completely, often inclined shaft enters Zheng Dong technology of caunching and exists and to caunch defect stable not, showing as inclined shaft, to enter positive hole undesirable, caunch and to subside or bracing frame collapses, and the defect of these constructing structures must effectively be repaired in time, just can guarantee engineering structures safety, therefore, for the problems referred to above, we propose a kind of inclined shaft and enter Zheng Dong and to caunch structure.
Utility model content
Prior art can not meet the needs of people, and for making up prior art deficiency, it is simple that the utility model aims to provide a kind of structure, and connect closely, bearing capacity is high, and the inclined shaft of easy construction enters Zheng Dong and to caunch structure.
For achieving the above object, the utility model is by the following technical solutions: a kind of inclined shaft enters Zheng Dong and to caunch structure, at least comprises frame supporting, concrete backfill district, frame navigation channel, supporting steelframe, Zheng Dong, bracing members post, inclined shaft, steel bracing plate, cover arch bow member and steelframe; Described fan-shaped frame supporting lower end arranges frame navigation channel; Between described frame navigation channel, concrete backfill district is set and upper end, concrete backfill district is covered by frame supporting; Lower end, described concrete backfill district arranges supporting steelframe; Described supporting steelframe bottom arranges positive hole and Zheng Dong side arranges bracing members post; Described bracing members post side arranges inclined shaft and one end weldable steel gripper shoe; Described steel bracing plate side is provided with cover arch bow member and cover arch bow member external surface welding frame navigation channel; Described cover encircles bow member top welding steel structure and steelframe is closely connected with the supporting of arc frame.
Further, described frame supporting is sector structure.
Further, it is inner that described positive hole is positioned at supporting steelframe, and positive hole is semicircular structure.
Further, described steelframe is I-shape construction.
Compared with prior art, the beneficial effects of the utility model are: branch's operation of caunching is less, and difficulty of construction is little, and the activity duration is short, after excavation, positive hole structure self-deformation is little, and fan-shaped frame supporting closing time is short, cause positive structure of the window convergent deformation, but its deflection is little, cracking phenomena is not obvious, significantly improve safety factor, excavation supporting face, outrigger positive hole changes straight line into by original curve, improves Safety construction technology.Because self convergent deformation of this structure is easy to control, reduce construction control difficulty, section headroom strengthens simultaneously, and construction safety is easy, is conducive to the safety of vehicle, has good promotional value.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of inclined shaft enters Zheng Dong and to caunch structure, at least comprises frame supporting 1, concrete backfill district 2, frame navigation channel 3, supporting steelframe 4, positive hole 5, bracing members post 6, inclined shaft 7, steel bracing plate 8, cover arch bow member 9 and steelframe 10; Described fan-shaped frame supporting 1 lower end arranges frame navigation channel 3; Between described frame navigation channel 3, concrete backfill district 2 is set and upper end, concrete backfill district 2 is covered by fan-shaped frame supporting 1; Lower end, described concrete backfill district 2 arranges supporting steelframe 4; Described supporting steelframe 4 bottom arranges positive hole 5 and positive side, hole 5 arranges bracing members post 6; Described bracing members post 6 side arranges inclined shaft 7 and one end weldable steel gripper shoe 8; Described steel bracing plate 8 side is provided with cover arch bow member 9 and cover arch bow member 9 external surface welding frame navigation channel 3; Described cover encircles bow member 9 top welding steel structure 10 and steelframe 10 and arc frame supporting 1 compact siro spinning technology.
As optimisation technique scheme of the present utility model: described frame supporting 1 is sector structure; It is inner that described positive hole 5 is positioned at supporting steelframe 4, and positive hole 5 is semicircular structure; Described steelframe 10 is I-shape construction.
As construction method of the present utility model: inclined shaft enter Zheng Dong caunch simultaneously in conjunction with mountain shed frame method as temporary support system, short excavation, fast to close, strong supporting, diligently to measure, the feedback guidance according to information construct, guarantees safety, stablizes.Inclined shaft enters flat slope section and still keeps benching tunnelling method construction method, carry out obliquely caunching and inclined shaft arch lift and raises in up/down steps arch, arrive and tangent position, positive hole, second end bottom elevation is appointed and is controlled by flat slope, step shortens, by left and right abutment wall with neat, smooth blasting or pre-arranged layer controlled blasting is adopted to excavate first sectional layer in construction, supporting tunneling boring adopts steelframe, inclined shaft and the positive hole angle of cut are more conducive to cavern's Stability Analysis of Structures more greatly, the corresponding reduction of difficulty of construction, intersect vertically with positive hole crossing the changing into of abutment wall, when slope construction is as positive hole outline excavation five cun of platforms, artificial drilling and blasting method excavates obliquely, often excavate one section and settle positive hole initial stage protective frame, form construction supporting system, sprayed mortar has backfilled construction.
