The concrete of b) precoating in each shoe brake door base plate;
C) mounting platform is built at the construction field (site);
D) be transported to job site be positioned on mounting platform by completing each shoe brake door base plate of precoating, and splicing puts in place;
E) joint grouting pipe is buried underground;
F) the rear fill concrete construction of bottom is carried out;
G) the joint grouting construction between the contact grouting construction of on-the-spot stitching portion and concrete is finally carried out.
Further, the method for building mounting platform described in comprises:
Build two concrete bands at the construction field (site), and the distance of two concrete bands is greater than the wheelspan of haulage vehicle;
At every bar concrete band top pre-embedded steel slab;
Steel plate is fixedly installed i iron platform, and the i iron platform on two concrete bands forms described mounting platform.
Further, also comprise before described step d): in the side wall concrete of both sides at the construction field (site), pre-buried i iron supports; On i iron supports, Chain block is installed, for lifting by crane completing the gate base plate of precoating and be positioned over mounting platform.
Further, during the concrete of precoating in gate base plate, the wing plate of gate base plate is upwards placed, builds to concrete concordant with wing plate, built and be transported to job site again in 7 days later.
The beneficial effect of patent of the present invention is, the present invention is applicable to Hydraulic and Hydro-Power Engineering gate construction of bottom plates, convenient construction, construction quality more easily ensures, expense cost is low, can ensure gate base plate and concrete gapless, reduces grouting works amount, grouting quality easily ensures, efficiently solves and first installs the gate base plate quality problems that cause of concreting and grouting more in the past.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.A kind of gate construction of bottom plates method, first gate base plate inner concrete of precoating outside the venue, concrete 2 of precoating outside the venue as shown in Figure 1, be transported to job site again and carry out the installation of gate base plate, then gate base plate bottom concrete is backfilled, backfill concrete 4 as shown in Figure 1, finally carry out the joint grouting between the contact grouting of on-the-spot stitching portion and concrete, concrete steps are as follows:
1) position that gate base plate will splice with job site is determined, at this position pre-plugged contact grouting pipe.Outside the venue before pre-cast concrete, first gate base plate is turned, then the contact grouting pipe of pre-buried gate base plate stitching portion, as shown in Figure 2, specifically need bury grout box 5, contact grouting inlet pipe 6 and contact grouting stack underground and to hold concurrently inlet pipe 7.
2) concrete of precoating in each shoe brake door base plate.After-pouring gate underplate concrete checked and accepted by grout pipe, builds to concrete concordant with wing plate, is transported to job site again and installs after having built 7 days.
3) mounting platform is built at the construction field (site).Build two concrete bands 10 at the construction field (site), and the distance of two concrete bands 10 is greater than the wheelspan of haulage vehicle (as flat car), as shown in Figure 4; At every bar concrete band 10 top pre-embedded steel slab 11; The i iron platform 12 steel plate 11 is fixedly installed on i iron platform 12, two concrete bands 10 forms mounting platform, as shown in Figure 5.And about platform between distance must ensure that flat car can pass through.When concrete band 10 intensity reaches more than 70%, carry out the transport of gate base plate 1, installation work.
4) in the side wall concrete 15 of both sides at the construction field (site), pre-buried i iron supports 13; Support on 13 at i iron and Chain block 14 is installed, for lifting by crane completing the gate base plate of precoating and be positioned over mounting platform.
5) be transported to job site be positioned over completing each shoe brake door base plate of precoating on mounting platform, and splicing puts in place.Utilize flat car to transport gate base plate to installation site, utilize Chain block 14 by gate base plate lift-off flat car, then flat car is driven away, then gate base plate is hung onto on erecting bed, and firmly support, and carry out scene splicing, as shown in Figure 6.
6) joint grouting pipe is buried underground.As shown in Figure 3, specifically need bury underground: grout box, joint grouting inlet pipe 8 and the double inlet pipe 9 of joint grouting exhaust.
7) the rear fill concrete construction of bottom is carried out.
8) the joint grouting construction between the contact grouting construction of on-the-spot stitching portion and concrete is finally carried out.After rear fill concrete has been constructed 60 days, first carry out contacts baseplate grouting, carry out base plate joint grouting construction after contact grouting completes, grouting construction completes after 28 days and carries out grouting quality inspection.
