The specific embodiment
In the present embodiment in the shield construction subway tunnel shield machine pushing tow tune method be to be undertaken by following process:
1, referring to Fig. 2, the base plate bed course is set in end well 8 makes and turn over beam and be capped, the base plate bed course is to form underlayer 1 by the auxilliary pad of rubble, establishes medium coarse sand and forms bed course 2 assisting on the underlayer 1; On last bed course 2, lay steel plate layer 3, with steel plate layer 3 as the shield machine carrier;
2, in end well 8, be positioned at and receive portal 9 places, the shield machine acceptance frame be set, receive shield machine (shown in Fig. 1-1), remove shield machine and be connected with each pipeline between chassis by the shield machine acceptance frame in steel plate layer 3 upper edge shield machine tunneling direction direction; One top-pushing mechanism is set, and is in the both sides of shield machine acceptance frame 5 pushing tow hydraulic jack 6 to be set, and pushing tow reaction frame 7 is fixedly installed on the steel plate layer 3; Utilize the pushing tow hydraulic jack shield machine to be moved to the middle part (shown in Fig. 1-2) of end well 8 through the shield machine acceptance frame on the steel plate layer;
3, be positioned at reception portal 9 places and extend the installation first road shape steel bracket 11 (shown in Fig. 1-3) along the shield machine tunneling direction and to opposite side; Be positioned at the portal place that starts and extend, the second road shape steel bracket 12 (shown in Fig. 1-3) is installed along the tune line direction and to opposite side; The chassis 13 that respectively saves that is arranged in current circuit at first gets into the first road shape steel bracket (11) (shown in Fig. 1-4); Begin to lift successively from the minor details chassis by crane then and respectively save chassis; Make and respectively save chassis successively behind the Rotate 180 degree; Be placed on the second road shape steel bracket (12) and go up (shown in Fig. 1-5); And withdraw to extending on the second outside road shape steel bracket (12) of end well, remove the first road shape steel bracket (11) subsequently and be positioned at the second road shape steel bracket (shown in Fig. 1-6) of end well;
4, utilize the collaborative pushing tow of each pushing tow hydraulic jack, and, make shield machine turning anticlockwise to 180 degree (shown in Fig. 1-7, Fig. 1-8, Fig. 1-9 and Fig. 1-10) through the shield machine acceptance frame;
5, utilize pushing tow hydraulic jack and the shield machine translation is arrived start portal position (shown in Fig. 1-11) once more through the shield machine acceptance frame, between shield machine and adjacent chassis, carry out subsequently pipeline is connected with front and back along connecing installation (shown in Fig. 1-12), completion is constructed.
Referring to Fig. 2,,, need handle tune shaft bottom plate for satisfying shield machine tune needs because of turning over 200mm on the plate-girder of tune shaft bottom.For avoiding shield machine jacking and decline repeatedly, the base pad layer height is set at 350mm; Underlayer 1 is a hardcore bed, and last bed course 2 is the medium coarse sand bed course, after setting cushion finishes and flattens, uses thickness to lay steel plate layer 3 as the steel plate of 30mm, and steel plate layer 3 is the direct carrier of shield machine 4.
Referring to Fig. 3, shield machine acceptance frame 5 is the steel sole plate 5b that are welded with four thickness 5mm in the bottom of a rectangular frame 5a, can increase the globality of shield machine acceptance frame 5 like this.
Shown in Figure 3 is the layout signal of pushing tow hydraulic jack; Shown in Figure 4 is the signal of pushing tow hydraulic jack longitudinal section.
When shield machine carries out translation, at first to guarantee to be fixedly installed on bracket 5c on the shield machine acceptance frame 5 with shield machine 4 and shield machine acceptance frame 5 firm welding, a pair of pushing tow hydraulic jack of selecting to be in phase the same side carries out the translation pushing tow; The a pair of pushing tow hydraulic jack that selection is on the diagonal position reverses end for end to rotate.
In the pushing tow process; The counter-force of pushing tow is converted into steel plate layer 3 and process rolls the friction between the last bed course 2 that is made up of medium coarse sand; Frictional force on steel plate layer 3 and the medium coarse sand between the bed course 2 is much larger than the frictional force between steel plate layer 3 and the shield machine acceptance frame 5; So the setting of pushing tow hydraulic jack 6 is steel members that welding one can be guaranteed rigidity on steel plate layer 3, as pushing tow reaction frame 7, between pushing tow hydraulic jack 6 and pushing tow reaction frame 7, force transmission rack 7a is set.
Before carrying out pushing tow, need along shield machine running orbit coating butter on steel plate layer 3, to reduce translation frictional force.
