Abstract
The invention provides a method for improving the second lining construction efficiency in a tunnel widening section. The method comprises the following steps of: firstly prefabricating a rotating platform comprising a tower formed by bracing pieces, wherein the top of the tower is provided with a lifting platform, and a rotating bearing is connected below the lifting platform and is connected with a lifting system; after the second lining construction is completed in the tunnel widening section, dragging a trolley for construction to the middle part of the widening section; arranging the rotating platform under the trolley, jacking upwards the trolley through a lifting system of the rotating platform, taking down traveling wheels at the bottom of the trolley and traveling wheel guide rails, and then rotating the trolley by 90 degrees; rotating the trolley in place, then arranging the traveling wheels back to the bottom of the trolley, laying the guide rails below the traveling wheels, dropping the trolley through the lifting system of the rotating platform, removing the rotating platform, dragging the trolley to pass through a master cave of the tunnel along the guide rails to reach the next widening section, rotating the trolley by 90 degrees through the rotating platform, and carrying out second lining construction in the next section.
Description
Technical field
The present invention relates to the job practices of a kind of tunnel widened section Second Lining Construction, be applicable to containing widened section such as the band long tunnel of widened section and the super long tunnel two lining constructions of stopping in emergency.
Background technology
Secondary lining is the tunnel construction form concrete lining cutting that applies of supporting inboard in the early stage, carried out under the condition of preliminary bracing in the tunnel, build inner lining with materials such as concrete, reinforce supporting to reach, optimize the route waterproof and water drainage system, beautify outward appearance, the effect of facilities such as communication, illumination, monitoring conveniently be set, to adapt to the requirement of modernized super expressway tunnel construction.
Figure 1 shows that the used chassis 1 of Second Lining Construction in the tunnel.Roller 11 is equipped with in chassis 1 bottom, and roller 11 belows are equipped with guide rail 2, and chassis 1 can move along guide rail 2.After one section two lining construction finished in the tunnel, along the tunnel chassis 1 traction to next section is constructed.But in some long tunnel and super long tunnel, usually just have a widened section to be used for establishing the band that stops in emergency at a certain distance, the tunnel width of establishing the band place of stopping in emergency is more many greatly than normal through tunnel master hole width, among Fig. 1,3 is main hole outline line, and 4 is the widened section outline line.As can be seen, the section of widened section is greater than main hole section, and also the width than normal through tunnel master hole is big to the span of the chassis of widened section two lining constructions.To a widened section two lining construction finish, in the time of need constructing to next widened section, widened section construction chassis can not be normally by master hole, tunnel, after traditional method is an each widened section two linings of having constructed, all will dismantle two lining chassis, re-assembly during to next widened section two lining construction again, dismounting, assembling process need the two weeks time at least usually, this method greatly reduces widened section two lining efficiencies of construction, has delayed the construction period.
Summary of the invention
The objective of the invention is at the low problem of present tunnel widened section two lining efficiencies of construction, a kind of method that improves tunnel widened section two lining efficiencies of construction is provided, can reach normal through tunnel master hole in the situation that does not need to dismantle the construction chassis, improve efficiency of construction indirectly, the reduction of erection time.
The present patent application people finds, the size of common widened section two lining chassis, although it is along the span of the tunnel lateral direction width greater than master hole, tunnel, but stand along the tunnel longitudinally length then less than the width in master hole, tunnel, thus, the applicant expects the stand half-twist, makes stand integral body by master hole, tunnel.
Technical scheme of the present invention is as follows:
A kind of method that improves tunnel widened section two lining efficiencies of construction is characterized in that:
(1) a prefabricated rotary stand, described rotary stand comprises the pylon of being made up of support bar, and the top of pylon is provided with lift platform, and the below of described lift platform connects swivel bearing, and described swivel bearing connects a jacking system;
(2) after widened section two lining constructions finished in the tunnel, the chassis of will constructing drew to the widened section middle part;
(3) rotary stand is arranged on chassis below, by the jacking system of rotary stand, with the chassis jack-up that makes progress, the travelling wheel of the pallet bottom of dismantling, and travelling wheel guide rail are then with the chassis half-twist;
(4) after chassis is rotated in place, travelling wheel is installed back pallet bottom, and below travelling wheel, lay guide rail, jacking system by rotary stand falls chassis, remove rotary stand, draw chassis by master hole, tunnel, to next widened section along guide rail, again by rotary stand with the chassis half-twist, carry out next section two lining construction.
The present invention is by with the stand rotation, can integral body move in master hole, tunnel, does not need to dismantle and re-assembly.Traditional widened section two lining job practicess, dismounting, rigging chassis once need 15 days at least, adopt method of the present invention that two lining formwork jumbos are moved to next widened section from a widened section, whole process can be finished in one day, shortened the time that two lining formwork jumbos switch the scope of operation greatly, improve efficiency of construction greatly, shortened the duration.

The specific embodiment
Below in conjunction with the drawings and the specific embodiments, method of the present invention is described.The present invention includes following steps:
(1) a prefabricated rotary stand.The structure of rotary stand 5 as shown in Figure 2, described rotary stand 5 comprises the pylon of being made up of support bar 51, the top of pylon 51 is provided with lift platform 52, the below of described lift platform 52 connects swivel bearing 53, described swivel bearing 53 connects a jacking system.This jacking system can adopt the hydraulic lifting system of prior art.
The main material of processing rotary stand pylon is i iron, angle steel, steel plate etc.The weight that stand and used bearing need can bear stand as calculated.
(2) after widened section two lining constructions finished in the tunnel, chassis 1 traction of will constructing was to this widened section middle part.Also to dismantle local members such as the thousands of jin of chassis, very heavy oil cylinder, ladder in case of necessity, to guarantee the chassis rotation enough gaps can be arranged.
(3) as shown in Figure 3, rotary stand 5 is arranged on chassis 1 below, by the jacking system of rotary stand 5, lift platform 52 is risen, with chassis 1 jack-up upwards, the travelling wheel 11 of the pallet bottom of dismantling, and the track 2 of travelling wheel below, then with the chassis half-twist.
During practical operation, can be earlier place backing plate 6 at lift platform, chassis is pushed up lift the position stressed evenly.
(4) as shown in Figure 4, after chassis 1 is rotated in place, travelling wheel 11 is installed back pallet bottom, and lay guide rail 2 again below travelling wheel 11, the jacking system by rotary stand falls chassis, removes rotary stand 5, along guide rail 2 traction chassis 1 by master hole, tunnel.To next widened section, again by rotary stand with the chassis half-twist.Chassis moves to next widened section with regard to integral body like this, carries out next section two lining construction.
