Abstract
The utility model provides a supporting assembly for an overlapped tunnel or a short-range construction tunnel. The supporting assembly is arranged in a tubular lining structure of the tunnel and comprises transverse H-type structural steel pieces which are arranged transversely and horizontally, longitudinal H-type structural steel pieces which are arranged longitudinally and vertically, pressure-bearing pipes, jacking pieces and steel corbels. At least one transverse H-type structural steel piece and at least two longitudinal H-type structural steel pieces are fixedly connected. The two ends of each transverse H-type structural steel piece are connected with the pressure-bearing pipes respectively. The top end of each longitudinal H-type structural steel piece is further connected with one pressure-bearing pipe. The jacking pieces are arranged between the pressure-bearing pipes and the inner wall of the lining structure. The base end of each jacking piece is an arc steel plate which can be attached to the inner wall of the lining structure. The tail end of each jacking piece extends into the corresponding pressure-bearing pipe. A top cap of each jacking piece is matched with the end face of the corresponding pressure-bearing pipe so that the base end of each jacking piece can abut against the lining structure and each top cap can be tightly pressed into the corresponding pressure-bearing pipe. The bottom ends of the longitudinal H-type structural steel pieces are welded to the steel corbels. The steel corbels are connected with the bottom of the lining structure.

Accompanying drawing explanation
The above and other feature of the present utility model, character and advantage are by by becoming more obvious below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 be an embodiment of the utility model overlap tunnel or the construction tunnel front view of supporting component closely.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
It should be noted that follow-up accompanying drawing is all only as example, it is not to draw according to the condition of equal proportion, and should be using this as the protection domain of the utility model actual requirement is construed as limiting.
As shown in Figure 1, overlap tunnel or closely construction tunnel supporting component be arranged in the liner structure 1 of tubulose in tunnel, this supporting component comprises a horizontal H shaped steel 3 that transverse horizontal arranges, longitudinally erects two longitudinal H shaped steel 4, pressure-bearing pipe fitting 6, jacking 2 and steel corbels 7 arranging.Laterally H shaped steel 3 and two longitudinal H shaped steel 4 are fixedly connected, the mode that is fixedly connected preferably bolt connects, on the place joining and horizontal H shaped steel 3 and/or longitudinal H shaped steel 4, be welded to connect the steel plate of use, by bolt 5, steel plate and corresponding longitudinal H shaped steel 4, the wing plate of horizontal H shaped steel 3 are solidly connected again, also can be other modes, for example between two longitudinal H shaped steel 4, weld a horizontal H shaped steel, weld respectively a H shaped steel at the side of longitudinal H shaped steel 4 again, three sections of H shaped steel arranging in same level direction like this form aforementioned lateral H shaped steel 3.In other embodiments, can also be that many parallel H shaped steel 3 join with longitudinal H shaped steel 4, longitudinally the quantity of H shaped steel 4 is also not limited to two, can be unnecessary two.
Laterally the two ends of H shaped steel 3 are connected with respectively pressure-bearing pipe fitting 6, longitudinally the top of H shaped steel 4 is also connected with pressure-bearing pipe fitting 6, between each pressure-bearing pipe fitting 6 and the inwall of liner structure 1, be provided with jacking 2, jacking 2 generally includes strut 23 and top cap 22, strut 23 has a cardinal extremity and an end, top cap 22 is nut form, strut 23 has spiro rod section, top cap 22 is on the spiro rod section of strut 23, in embodiment as shown in Figure 1, the cardinal extremity of strut 23 is that curved plate 21 can be fitted with liner structure 1, end extend in pressure-bearing pipe fitting 6, cap 22 rotations in top are supported with the end of pressure-bearing pipe fitting 6, between liner structure 1 and pressure-bearing pipe fitting 6, form and support, this is supported power and makes whole supporting component play firmly supporting role, longitudinally bottom and the steel corbel 7 of H shaped steel 4 weld, steel corbel 7 is also connected with the bottom of liner structure 1.
