The specific embodiment
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, the counterforce device that starts in a kind of shield machine hole, the described counterforce device that starts is arranged on the rear portion of shield machine 6 shield bodies, and the described counterforce device that starts includes reaction frame 1, counter force wall 2 and steel and supports 3; Start described in described reaction frame 1 the is positioned at front portion of counterforce device, the structure of described reaction frame is structure existing, ripe in prior art, at this, do not do too much explanation, in this embodiment, described reaction frame adopts the structure shown in Fig. 5-Fig. 6, described reaction frame is assembled by steel construction piece, and the center of reaction frame has the rear supporting polygonal hole matching with shield machine 6 shield body rear portions, makes the rear supporting polygonal hole through having on reaction frame at shield machine 6 shield body rear portions; Described counter force wall 2 is positioned at the rear portion of described reaction frame 1, and described reaction frame 1 supports 3 by steel and is supported on counter force wall 2; Described steel supports 3 for to make a plurality of by the steel pipe of Φ 400mm; In conjunction with Fig. 2-Fig. 4, described counter force wall 2 is built and is formed by steel concrete, and described counter force wall 2 includes counter force wall body 4 and counter force wall ear wall 5; Anchor rib anchoring reserved on one side of described counter force wall body 4 and the abutment wall in tunnel 7 is integrated; The bottom of described counter force wall body 4 and counter force wall ear wall 5 is connected with embedded bar before tunnel floor construction, guarantees when thrust is large not to be subjected to displacement; The center of described counter force wall body 4 has the rear supporting polygonal hole matching with shield machine 6 shield body rear portions; Make the rear supporting polygonal hole through having on counter force wall body at shield machine 6 shield body rear portions; Described counter force wall ear wall 5 is set to trapezoidal, described counter force wall ear wall 5 is positioned at tunnel 7 central sides and is positioned at the rear portion of described counter force wall body 4 one sides, described counter force wall ear wall 8 arranges perpendicular to counter force wall body 4, and in tunnel, central side provides stable support function to counter force wall.
Tunnel, the Shenzhen and Hong Kong 9.6m shield machine of take below starts as example practical process of the present utility model is illustrated in Mining Method tunnel:
For the ease of reaction frame 1 installation and removal, before Mining Method constructing tunnel two linings, the first pre-buried hanger of installing, dismantling for reaction frame, reaction frame resolves into some fritters, adopts transport vehicle to be transported to the originating terminal of shield machine, then bottle gouard moved by hands is hung on the hanger being embedded in advance in two linings, and lifting reaction frame is assembled, and wherein hanger used adopts the reinforcing bar of Φ 32, the counter force wall 2 that the reinforced concrete wall that blocks up thick 2m of first constructing in Mining Method tunnel supports as reaction frame, the rear supporting polygonal hole through having on reaction frame 1 and counter force wall 2 at shield machine shield body rear portion, make reaction frame 1 be positioned at the rear portion of shield machine 6 shield bodies, a plurality of jack that are uniformly distributed along the circumference are installed on the front end face of reaction frame 1, make jack act on shield machine 6, the reaction force acts of jack is on reaction frame 1 simultaneously, the power on reaction frame 1 of acting on supports 3 by steel and is delivered on counter force wall 2, because counter force wall 2 is more firm, so reaction force provides thrust just to advancing of shield machine 6, complete starting of shield machine.
