Abstract
The utility model discloses support frame is pour to tunnel secondary belongs to the tunnel support field, and the purpose provides swift, easy to assemble and a transport support frame is pour to tunnel secondary. Including buckled plate and fixing rivet, its characterized in that, the support frame is pour to the secondary, and the concatenation forms according to tunnel shape size by the multiunit buckled plate to fasten with fixing rivet in adjacent buckled plate junction. Adopting the buckled plate concatenation to put up the support frame that forms and need not removing and install convenient after building the completion, the support frame will become the bearing structure in tunnel, consequently can play the tunnel better and support and the guard action, avoid the deformation of subsiding that the tunnel strutted not as good as result in often, and then cause construction safety.
Description
Technical field
The utility model relates to a kind of support of tunnel device, and particularly tunnel secondary builds bracing frame.
Background technology
Infrastructure construction is in recent years greatly developed, and especially the construction of speedway and railway increases, and the Mountain Debelopment that multidirectional with a varied topography, gully is connived, therefore construction of tunnel inevitably increases.Construction method is commonly used in present tunnel New Austrian Tunneling Method, Mining Method, tunnel boring machine method, maximum with New Austrian Tunneling Method again.New Austrian Tunneling Method is based on the self-stable ability safeguarded and utilize country rock, using shotcrete integration as supporting means, makes country rock become the ingredient of support system, controls the distortion of country rock better with lax.After tunnel excavation, build one deck flexible thin wall liner in time and build, by enclosing rock measure, determine that surrouding rock deformation builds waterproofing course and secondary lining after stable.The mode of present secondary lining many employings tunnel lining trolley, be specially and lay splash guard and reinforcing bar below rough tunnel, then a smooth circular arc mould is propped, gap in the middle of mould and tunnel wall by concrete from the bottom up primary concreting tamp, the tunnel smooth in appearance after solidifying, firmer.But there is the shortcoming of building complexity, transport inconvenience in tunnel lining trolley.And in major long tunnel, temporary parking position can be set usually; tunnel radius is herein obviously more local than other large many; and adopt during tunnel lining trolley and significantly can not change radius; only has replacing template; and tunnel lining trolley needs repeatedly to change radius sometimes; thus make construction become very complicated more, add the difficulty of construction.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of convenient tunnel secondary installed and transport and builds bracing frame.
The utility model solves the technical scheme that its technical problem adopts, tunnel secondary builds bracing frame, comprises corrugated sheet and fixing rivet, it is characterized in that, support frame as described above is spliced to form according to tunnel-shaped size by organizing corrugated sheet more, and fastening at adjacent corrugated plate junction fixing rivet.
Further, described secondary build bracing frame by corrugated sheet ripple elongated end along tunnel longitudinal direction splice form.
Further, described secondary build bracing frame by corrugated sheet ripple elongated end along arched tunnel direction splice form.
Further, longitudinal junction at two ends, described corrugated sheet plate face is provided with double screw, and lateral connection place is provided with single screw, and described double screw and single screw are all arranged on corrugated sheet crest.
Further, described corrugated sheet embeds fixing formation secondary in tunnel bottom layer of concrete preformed groove and builds bracing frame pedestal.
The beneficial effects of the utility model are: adopt corrugated sheet to splice the tunnel secondary built and build bracing frame can adjust arbitrarily bracing frame shape and size according to the shape size in tunnel, avoid and adopt tunnel lining trolley to carry out the problems such as the complicated operation run into when secondary is built.Adopt tunnel lining trolley to carry out secondary when building, after having built one section of tunnel, lining trolley will remove, and continue to build next section of tunnel.And the bracing frame adopting corrugated sheet to splice to build can not remove after having built and installation and transportation are convenient; bracing frame will become the braced structures in tunnel; therefore support and protective effect can be played to tunnel better; avoid tunnel support to cause sedimentation and deformation not in time, and then cause construction safety.

Fig. 3 is tunnel lateral direction sectional view.
Fig. 4 is corrugated board structures schematic diagram.
In figure, 1-builds bracing frame bis-times, 11-corrugated sheet, the double screw of 111-, the single screw of 112-, 3-LIFT, 4-tunnel wall.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, tunnel secondary builds bracing frame, comprises corrugated sheet 11 and fixing rivet 2, and described secondary is built bracing frame 1 and according to tunnel-shaped size is spliced to form by organizing corrugated sheet 11 more, and fastening at adjacent corrugated plate 11 junction fixing rivet 2.
The corrugated of the arc-shaped wave card 11 of monomer can be sinusoidal circular arc ripple, triangle ripple, trapezoidal ripple or arcuate bead, and polylith corrugated sheet 11 can be circular, ellipse, arch or the shape of a hoof after splicing, and bracing frame shape determines according to the shape in tunnel.Use the splicing of many group corrugated sheets 11 to build tunnel secondary and build bracing frame, the block number of corrugated sheet 11 can be changed arbitrarily according to the size in tunnel, thus make bracing frame tunnel wall of can fitting well be convenient to build mixed earth.And adopt corrugated sheet 11 to splice bracing frame, make the transport of material more convenient, and construction is also easier.Between adjacent corrugated plate 11, junction uses fixing rivet 12 fastening.
Preferably, as shown in Figure 1 and Figure 2, described secondary build bracing frame 1 by corrugated sheet 11 ripple elongated end along tunnel longitudinal direction splice form.
Secondary is built bracing frame 1 and is spliced by corrugated sheet 11, and a kind of embodiment is: corrugated sheet 11 ripple elongated end is along tunnel longitudinal direction splicing composition bracing frame.
Preferably, as shown in Figure 3, described secondary build bracing frame 1 by corrugated sheet 11 ripple elongated end along arched tunnel direction splice form.
Secondary is built bracing frame 1 and is spliced by corrugated sheet 11, and another kind of embodiment is: corrugated sheet 11 ripple elongated end is along arched tunnel direction splicing composition bracing frame.
Preferably, as shown in Figure 4, longitudinal junction at two ends, described corrugated sheet 11 plate face is provided with double screw 111, and lateral connection place is provided with single screw 112, and described double screw 111 and single screw 112 are all arranged on corrugated sheet 11 crest.
Longitudinal junction at corrugated sheet 11 upper face two ends is provided with double screw 112, and pitch of holes is 40 ~ 90mm, and use double screw 112 that adjacent corrugated sheet 11 can be made to be connected more firm, using bolt to fix can be easy for installation and removal.The steel plate thickness of corrugated sheet 11 is 3.0 ~ 8.0mm, and its pitch of waves is 400mm, and wave height is 150mm, and spliced is 4000 ~ 25000mm across footpath.
Preferably, described corrugated sheet 11 embeds fixing formation secondary in tunnel bottom layer of concrete and builds bracing frame 1 pedestal.
First subwave card 11 to be vertically fixed in tunnel bottom layer of concrete preformed groove as bracing frame pedestal when secondary builds bracing frame 1 starting to build, to be convenient to the splicing remaining corrugated sheet 11.
