Before construction, according to construction design drawing inter-road road size, chassis is carried out processing and fabricating, chassis will possess certain intensity and rigidity, in use must not be out of shape, and accomplish advantages of simple, and is easy to use.
A kind of job practices of utilizing above-mentioned chassis construction coal mine roadway, the concrete operations step is following:
1, lays track;
2, utilize running gear, be installed on the track chassis is in place;
3, measure the construction control line, utilize leading screw and jack adjustment template;
4, build the tunnel concrete;
5, etc. after concrete strength meets the demands, adjustment leading screw and jack disengaging template, template cleaning brush oil is for use;
6, lay next construction section track, repeat above-mentioned work progress.
The invention has the beneficial effects as follows: solved the concrete leakiness that the two lining concrete constructions of traditional tunnel cause, the presentation quality defect of bad has guaranteed concrete Forming Quality, and easy to operate.

Among the figure: 1, track, 2, wheel, 3, longeron down, 4, motor, 5, column, 6, diagonal brace; 7, side form, 8, bolt, 9, go up longeron, 10, backform, 11, crossbeam, 12, longeron; 13, leading screw, 14, the 8# angle steel, 15, the 16# channel-section steel, 16, charging aperture, 17, jack, 18, operating platform.
The specific embodiment
Like Fig. 1 and Fig. 2, Fig. 3 and shown in Figure 4, it comprises template, template support, running gear and operating platform with chassis in the tunnel concrete construction; Template supports by crossbeam 11 and symmetry and is installed in the column 5 below the crossbeam 11, the gate-type bracing frame that diagonal brace 6 is formed; Template is by backform 10 and the arch gate-type template that forms with side form 7 that backform is fixed together; Template is through being supported on the crossbeam 11 that template supports being much of longeron 9; Crossbeam 11 is formed horizontal skeleton with longeron 12; Template is bearing on the running gear, and described running gear comprises the following longeron 3 that is installed on column 5 lower ends, be installed in down wheel 2 and the motor 4 of wheels motion below the longeron 3; Described operating platform 18 has 2, is installed on the formwork-support each one of front and back respectively.Template supports according to the tunnel size to be confirmed, adopts the gate-type bracing frame of H shaped steel welding.The backform 10 of template adopts bolt to be connected with side form 7.Longeron 12 two ends of supporting in template respectively are equipped with 2 jack 17; On column 5, be welded with leading screw 13.
The concrete preparation method of present embodiment chassis is:
1, template supports: make column 5, diagonal brace 6 and crossbeam 11 earlier; Column 5 adopts H shaped steel 250*180 with diagonal brace 6; Crossbeam 11 adopts H shaped steel 350*170, and length is 2.4 meters, 2 meters of spacings, totally 8; Weld through the 16# channel-section steel between crossbeam and the column.Install longeron 9 and following longeron 3 again, last longeron adopts 16# channel-section steel and H shaped steel 200*200, couples together up and down with crossbeam 11; Following longeron 3 adopts H shaped steel 350*350.After treating that template is installed, jack 17 and leading screw 13 are installed again, the QYL50 jack, is installed on the longeron 12 by 2 every; Leading screw 13 is welded on the column 5.
2, template is installed: per 1.5 meters one of template, and totally 7,10mm is thick, and backform 10 adopts bolt to be connected with side form 7.Welding 16# channel-section steel 15 on the template corresponding with leading screw 13, other positions welding 8# angle steel 14, spacing 250mm makes template have enough rigidity.
3, running gear is installed: template support with walking track 1 between adopt under longeron 3 be connected, wheel 2 is equipped with in following longeron bottom surface.The track model is 38 ㎏/m, 2.3 meters of spacings, and power set are Y100L2-4B5 motor 4, are installed in down on the longeron 3, and the power of walking is provided.
