Abstract
The overall station-crossing construction method of shield machine is the construction method that cannot provide enough place, condition or carry out when construction period is urgent to the export & import of shield structure at station of completing.Two groups of wheels are each side welded at anterior shield, middle shield, after wheels installation, in the below of roller, approach rail is installed, approach rail is connected with station track alignment, after approach rail installation, shield body is slowly fallen, the wheels be integrally connected with shield body are accurately placed on approach rail, then adopt 2 groups of jack+counter-force strut to advance shield body; By replacing the mode of mobile counterforce device position and telescopic jack, make above the continuous pushing tow of shield body to the pedestal that starts; After shield body locates, chassis locomotive haulage misses the stop.The overall station-crossing construction method of shield machine of the present invention, reduces construction risk, avoids the lifting operation of shield body, greatly reduce the security control risk of construction in this engineering method translation motion, ensure that the construction safety that shield body entirety is missed the stop.
Description
Technical field
The present invention relates to field of civil engineering, specifically relate to the overall station-crossing construction method of shield machine that cannot enough place, condition are provided or carry out when construction period is urgent to the export & import of shield structure at station of completing.
Background technology
In the subway Line 1 work progress of Hefei, way station the beginning and the end mileage in water Yangjiang is K11+486.515 ~ K11+685.615, station is double-layer double-span an island platform station, station total length 199.1m, station width 20.1 ~ 23.7m, miss the stop the minimum clear span 6.5m in region (with structure side wall clear distance between the vertical lift of station), clear height 7.45m, shield machine diameter 6.28m.Project management department checks the structure headroom of water Yangjiang way station and design elevation, basically identical with design drawing, and because water Yangjiang way station is station of completing, shield machine cannot adopt the general operating type hanging out and hang in carry out construction of missing the stop.
Summary of the invention
For the technical problem existed in prior art, the object of the present invention is to provide the overall station-crossing construction method of a kind of shield machine.
To achieve these goals, the technical solution adopted in the present invention is: the overall station-crossing construction method of a kind of shield machine, comprise preparation of construction, the installation receiving pedestal, the laying of the track that misses the stop successively, shield machine receive, shield body disintegrates with chassis, the translation of shield body and longitudinal-moving device welds, the welding of wheels, shield body miss the stop, chassis draw miss the stop, shield machine starts again; Two groups of totally 4 80t level wheels are each side welded at anterior shield, middle shield, wheels between left and right distance are 4.6m, front and back are 1m apart from the distance of the shield body weight heart (apart from cutter head panel 2675mm) position, after wheels installation, install approach rail in the below of roller, approach rail is connected with station track alignment, after approach rail installation, shield body is slowly fallen, the wheels be integrally connected with shield body are accurately placed on approach rail, then adopt 2 groups of 100T jack+counter-force strut to advance shield body; The every vertical shift 3m of shield body is a circulation, by replacing the mode of mobile counterforce device position and telescopic jack, makes above the continuous pushing tow of shield body to the pedestal that starts; After shield body locates, chassis 45T locomotive haulage misses the stop.
The overall station-crossing construction method of shield machine of the present invention, its beneficial effect shows:
1, reduce construction risk, avoid the lifting operation of shield body in this engineering method translation motion, greatly reduce the security control risk of construction, ensure that the construction safety that shield body entirety is missed the stop.
2, improve efficiency of missing the stop high: roller in orbit walking resistance is little, also adapt to certain bend and gentle slope, namely direction is controlled, safety improves, and meanwhile, two jack adopt UNICOM's oil pipe, and fltting speed is stablized, ensure that synchronism and the stability of shield body movement.Make adequate preparation at the scene, in the rational situation of construction organization, the right line of shield structure 3 days shield bodies miss the stop smoothly.
3, cost is lower, miss the stop than parallel-moving type entirety or the miss the stop personnel, material, the facility that use of split all few, material therefor in the traversing and vertical shift process of shield body, facility are all reusable.
4, various pipeline and the circuit of shield machine need not be disconnected, can not secondary pollution be caused.Also need not carry out secondary start before debugging.
5, the use of the method decreases the retrofit work amount that shield machine entirety is missed the stop; Decrease the quantity of the required construction material that misses the stop, saved construction cost, shortened the construction period greatly, achieve shield machine and miss the stop safely.Have a extensive future, can promote the use of.
Accompanying drawing explanation
Fig. 1 is the workflow diagram of the overall station-crossing construction method of shield machine of the present invention.
Detailed description of the invention
For further describing the overall station-crossing construction method of shield machine of the present invention, below in conjunction with accompanying drawing, it is described further.
Refer to shown in Fig. 1, the overall station-crossing construction method of a kind of shield machine, comprise preparation of construction, the installation receiving pedestal, the laying of the track that misses the stop successively, shield machine receive, shield body disintegrates with chassis, the translation of shield body and longitudinal-moving device welds, the welding of wheels, shield body miss the stop, chassis draw miss the stop, shield machine starts again; Two groups of totally 4 80t level wheels are each side welded at anterior shield, middle shield, wheels between left and right distance are 4.6m, front and back are 1m apart from the distance of the shield body weight heart (apart from cutter head panel 2675mm) position, after wheels installation, install approach rail in the below of roller, approach rail is connected with station track alignment, after approach rail installation, shield body is slowly fallen, the wheels be integrally connected with shield body are accurately placed on approach rail, then adopt 2 groups of 100T jack+counter-force strut to advance shield body; The every vertical shift 3m of shield body is a circulation, by replacing the mode of mobile counterforce device position and telescopic jack, makes above the continuous pushing tow of shield body to the pedestal that starts; After shield body locates, chassis 45T locomotive haulage misses the stop.
The Third Construction Co., Ltd. is in the subway Line 1 work progress of Hefei, technician is by the on-the-spot construction technology adopting the overall station-crossing construction method of shield machine, preferably resolve technique on shield machine's station-crossing problem, and the operating mode that shield machine entirety is missed the stop is analyzed, draw the clear superiority of this kind of construction method in duration, economic dispatch: effectively improve construction speed, ensure that construction safety, save construction cost.The overall station-crossing construction method of this Novel shield machine is used in way station (left and right line) the technique on shield machine's station-crossing construction of Hefei track traffic Line 15 Biao Shui Yangjiang in December, 2014 and in January, 2015.
Above content is only to design example of the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
