Background technology
Authorization Notice No. is that the patent of invention of CN101550829B discloses a kind of shield whole self-propelled station-crossing construction method, and step is as follows: guide table of missing the stop arranges some groups of reaction holes; After shield machine receives and pushes to guide table of missing the stop, between first group of reaction holes and shield machine shield tail, place semi-ring section of jurisdiction; Counter-force post is inserted in reaction holes; Shield structure jack pushes away semi-ring section of jurisdiction, advances, releases after a segment distance, retraction shield structure jack, hang out semi-ring section of jurisdiction, extract counter-force post until shield structure jack, counter-force post is inserted in the reaction holes of next group adjacent, continues above process; Circulation is advanced until shield machine pushing tow to precalculated position.
Prior art, by inserting counter-force post missing the stop in guide table in reserved reaction holes, utilizes shield structure jack to push away the method for advance, realizes the object of shield whole self-propelled station-crossing.Prior art Problems existing one adopts relatively independent counter-force post, considers the factors such as the Rigidity and strength of column, and its pushing reaction that can provide is little, and counter-force conduction system is not also optimized, and easily damages hole periphery guide table concrete; Two is that reaction holes pre-sets, and crossing, tunnel curved section versatility is poor, is unfavorable for the pose adjustment of shield machine in curved section pushing tow process.
Utility model content
The technical problems to be solved in the utility model is to provide a kind ofly can provide larger pushing reaction, can not damage reserving hole, large jacking force shield machine air that versatility is good and rational in infrastructure pushes through hole truss-like reaction support group.
In order to solve the technical problem that the utility model proposes, the utility model discloses a kind of large jacking force shield machine air and push through hole truss-like reaction support group, it is characterized in that comprising crossbeam, column group, diagonal brace, described column group comprises at least two row's three row columns, be fixedly connected with by diagonal brace between described often row column, described crossbeam is fixedly connected with the first row column of described column group.
Above-mentioned large jacking force shield machine air pushes through the advantage that hole truss-like reaction support group makes full use of truss-like reaction support group space combination structure,---first row column---the counter-force conduction mode of concrete guide table that diagonal brace---arranges column---afterwards that passes through crossbeam, greatly optimize counter-force conduction system, be assigned with the stressed of each structure of bearing group and concrete guide table rationally and effectively, while bearing group structure and guide table concrete not being damaged, the effect of enough large pushing reaction can be provided again; Simultaneously to push through the versatility of hole truss-like reaction support group good for the large jacking force shield machine air of the utility model, has both been suitable for shield machine tunnel straightway sky and pushed through hole, be applicable to again tunnel curved section sky and push through hole; And the large jacking force shield machine air of the utility model pushes through hole truss-like reaction support group and can change girder system by adjustment column radical and spacing and diagonal brace length, thus different end reactions is provided, the requirement of attitude of shield machine adjustment in pushing tow process can be met.
Improve as one of the present utility model, the end face of described crossbeam and the first row column end face of column group are in sustained height.Crossbeam end face and column end face are in sustained height can guarantee that crossbeam is as there being larger contact surface during stress surface.
Improve as one of the present utility model, described crossbeam adopts H profile steel and Plate Welding to form.
Improve as one of the present utility model, described crossbeam is fixedly connected with by the mode of welding with the first row column of described column group.
Improve as one of the present utility model, described diagonal brace and horizontal direction angle are 30 ° ~ 45 °.When diagonal brace and horizontal direction angle are 30 ° ~ 45 °, the transmittance process of power is more reasonable, stressed evenly.
Improve as one of the present utility model, described diagonal brace adopts H profile steel and Plate Welding to form.
Improve as one of the present utility model, described column is fixedly connected with by the mode of welding with diagonal brace.
Improve as one of the present utility model, the column of described composition column group is seamless steel pipe.
Generally speaking the beneficial effects of the utility model are as follows:
1, there is good counter-force conduction system, in pushing tow process, not easily the structure of hole truss-like reaction support group is pushed through to large jacking force shield machine air and guide table concrete damages, and can push through for shield structure sky the pushing reaction that hole provides larger;
2, highly versatile, had both been suitable for shield machine tunnel straightway sky and had pushed through hole, and be applicable to again tunnel curved section sky and push through hole, and can meet the needs of attitude of shield machine adjustment in pushing tow process.
Accompanying drawing explanation
Fig. 1 the utility model stereogram;
Wherein: 1-crossbeam, 2-column group, 3-diagonal brace.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, the utility model comprises these three parts of crossbeam 1, column group 2 and diagonal brace 3.Column group 3 comprises 6 root posts, described column is all identical and line up two row three row, and the column forming column group 2 adopts external diameter 30cm, the seamless steel pipe of wall thickness 4cm, and when being inserted into by column in concrete guide table, column exposes the height of concrete guide table a little more than section of jurisdiction upper surface lowest part; Crossbeam 1 adopts the H profile steel of 300*300*10*15mm and Plate Welding to form, then by crossbeam 1 rigid solder on the first row column of column group 2, crossbeam 1 end face and first row column end face are on sustained height; Diagonal brace 3 adopts the H profile steel of 200*200*8*12mm and Plate Welding to form, diagonal brace 3 one end is with first row column rigid solder, the other end is with second row column rigid solder, and diagonal brace 3 and level are 30 ° ~ 45 ° to angle, and the length of diagonal brace 3 can need to arrange flexibly according to pushing tow.
The disclosed large jacking force shield machine air of the utility model pushes through the stress point that hole truss-like reaction support group is used as shield machine advance, before shield machine pushing tow each time, the large jacking force shield machine air welded is pushed through hole truss-like reaction support group and winches to reaction holes group place by the crane hoisting equipment on shield machine, again column group 2 is anchored in corresponding reaction holes, large jacking force shield machine air pushes through placement section of jurisdiction, truss-like reaction support group front, hole and utilizes large jacking force shield machine air to push through hole truss-like reaction support group to block section of jurisdiction, during jack pair section of jurisdiction applied thrust on shield machine, thrust is delivered to large jacking force shield machine air by section of jurisdiction and pushes through hole truss-like reaction support group,---first row column---the counter-force conduction mode of diagonal brace 2---second row column---concrete guide table afterwards through crossbeam 1, then shield machine is advanced the propulsive thrust producing this thrust.
The foregoing is only better embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, the structural modification that local is small may be there is in implementation process, if do not depart from spirit and scope of the present utility model to various change of the present invention or modification, and belonging within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
