Description

Be used for light section tunnel vault lining cutting slidingtype chassis
Technical field
The utility model belongs to the tunnel construction equipment technical field, specifically, is a kind of slidingtype chassis for the lining cutting of light section tunnel vault.
Background technology
In recent years, along with the energetically adjustment of China's energy strategy, light-gauge mountain tunnel passes through engineering and uses more and more, and also more and more higher to the requirement of duration, quality in gas transmission, oil transportation, water pipeline.At these net sections less than 20m 2The light section tunnel construction in, the vault lining construction is difficulty the most, owing to be subject to spatial constraints, sets up all very inconvenience of support and concreting, not only progress is slow, and difficult quality guarantee.So tunnel top board construction, the lining trolley that should adopt integral assembling, turnover to use, for CN200820103730.4 a kind of tunnel development synchronous lining formwork trolley is disclosed such as Chinese patent application number, relate to development machine TBM construction driving simultaneously and the construction equipment that is connected of the collaborative follow-up of secondary lining operation, be fixedly connected with along the door frame crossbeam of tunnel direction bottom girder and vertical tunnel axis; Walking mechanism is fixed under the bottom girder; On move in length and breadth beam assembly and upper longeron and be fixed in the bottom girder top by door frame column two and door frame column one; The backform crossbeam is fixed in and moves in length and breadth on beam assembly and the upper longeron; Backform column bottom fixing with the backform crossbeam on, top the make progress short template of jacking and long template; One end is fixed on door frame column one, the column two or the screw mandrel in the bottom girder outside holds out against the limit mould laterally.Chinese patent application number discloses a kind of tunnel bogie for all ring integral form-construction lining form for CN03117190.7, its formation comprises the Vierendeel girder with telescopic front and back bearing and front and back anti-floating platform, be installed in the vehicle frame on the Vierendeel girder, be installed on the vehicle frame various template oil cylinders and corresponding be connected to the different templates on each oil cylinder and be installed in Vierendeel girder and vehicle frame between the guide wheel guide rail structure, described Vierendeel girder is an open web type Vierendeel girder, bottom at Vierendeel girder is covered with conveying track, and two ends are provided with the sloping rail that joins with this conveying track.
But the finished product chassis of selling in the market is hundreds thousand of easily, and is for the little lining project of a lot of engineering quantitys, extremely uneconomical; And generally all can there be at the construction field (site) a large amount of steel materials idle; Therefore, be badly in need of on the market that design a kind ofly can be gathered materials on the spot, field fabrication, easy and simple to handle, cheap slidingtype lining trolley.
Summary of the invention
The purpose of this utility model is for the contradiction that solves between lining construction in a small amount and the expensive market finished product chassis input, provides a kind of and can gather materials on the spot, field fabrication, easy and simple to handle, the cheap light section tunnel vault lining cutting slidingtype chassis that is applicable to.
To achieve these goals, the utility model has adopted following technical scheme: a kind of for light section tunnel vault lining cutting slidingtype chassis, and comprise template, template backrest, bracing frame and be located at the walking mechanism of bracing frame bottom; Described template is fixedly mounted on the template backrest, and the integral linear of template is determined by the shaped upper part of template backrest, and is consistent with liner structure; Contact surface in template and template backrest is provided with preformed hole, and vibrator is installed; Described template backrest is made of backrest steel pipe and reinforcing bar mould bases.
Support frame as described above comprises jacking and bracing frame steel pipe, and bracing frame is erected at template backrest below by jacking.
Described walking mechanism comprises castor, i iron and crossbeam, and castor is installed on the i iron, i iron and crossbeam fixed installation.
Described crossbeam is comprised of some i iron or channel-section steel.
Described vibrator is the absorption type vibrator.
Described template backrest is comprised of some reinforcing bars and steel pipe.
All parts of the present utility model fits together by bolt or welding or hinged etc. mode, consists of the finished product chassis.
Chassis of the present utility model is when sliding, can be by the Telescopic of jacking, regulate the height of top template, guarantee certain upper space, because the lining cutting top mostly is the up-narrow and down-wide designs such as the shape of a hoof or arc, when template descended the formation upper space, left and right sides had also pulled open certain distance with the lining cutting side wall so simultaneously, when avoiding chassis to move, wipe at most section and side wall.After chassis slides into the target location, pass through again the jacking adjusting template to corresponding height, this moment, the template both sides were just in time tangent with the side wall liner structure, after the closed end template, closed before and after forming, about the smooth-going vault concrete storehouse of overlap joint, the preformed hole that puts in storage by the template top carries out concrete and builds at last; During form removal, by rotation jacking snap ring, lay down the active force that supports the template backrest, template and backrest break away from the concrete face under Gravitative Loads, realize the demoulding.
Concrete using method of the present utility model:
A. build in advance the chassis track of advancing, accurate unwrapping wire when building, guarantee track width, planeness and trend satisfy chassis advance require and rear position deviation in place in allowed band;
B. reduce the template height by the snap ring of regulating jacking, when forming upper space, can allow the chassis left and right sides and lining cutting side wall maintain a certain distance;
C. utilize lever principle to realize that with crowbar chassis moves;
D. after chassis moves into place, utilize the jack pair support system to support in advance, jack model and quantity should satisfy concrete load requirement when building;
E. regulate the snap ring of jacking, climbing shuttering backrest height, so that template is adjusted to the locations of structures of lining cutting concrete design, this moment, the template both sides were just in time tangent, closed with lining cutting side wall concrete;
F. carry out end head formwork Zhi Li, masterplate place in termination reserves the concrete hole of putting in storage, and finishes storehouse face die plate construction;
G. inject concrete from the template preformed hole, open and be attached to the template upper vibration generator, concrete vibrating is closely knit;
H. arrive form removal length of time, regulate the snap ring of jacking, reduce the template height and realize the demoulding, then cleaning template and smearing release agent just can continue next lining cutting section construction.
Compared with prior art, the beneficial effect that possesses of the utility model:
Gather materials on the spot, field fabrication, easy and simple to handle, cheap.Because what the utility model adopted is the mode that integral assembling, turnover are used, higher and the easy operation of Use Limitation rate, and used main material such as channel-section steel, reinforcing bar, punching block etc., all can directly obtain from the job site, be easy to after the use reclaim, avoided market finished product chassis depreciation, the occupation of capital and the factor such as invisible abrasion when idle, economic benefit is high.
