50cm, every guide pile bottom are b beyond pre- foundation pit bottom depth of digging, b=20-40cm, along the side that guide pile is crowded around when excavation
Shape region is dug down, the foundation pit until digging out predefined size.
Further, the silt dug out in Excavation Process is needed far near coal-mine 1m or more, foundation depth tolerance
For+100mm, -50mm.
Further, the bundle muscle formwork specifically includes the following steps:
A1: assembling reinforcement: several pieces of pad bricks first are laid with as protective layer at foundation pit bottom, bind bottom plate muscle, bottom on pad brick
There are the spacing of 5-8cm between plate muscle and foundation pit walls, and column muscle is then bound on bottom plate muscle；
A2: template installation: template uses rigid material, and template is installed to four side of column muscle one by one and is mutually fastened,
Foundation pit walls set up support rod and push against all templates.
Further, the basis pour specifically includes the following steps:
B1: it according to concrete proportioning by raw material using mechanical stirring or artificial stirring, prepares it after concrete from mould
Pouring operation is carried out at the top of plate, the concrete being stirred continuously in template in casting process makes it uniformly；
B2: starting after casting in 12 hours to molding basic stand column water seasoning, when maintenance on the outside of template
Add overcover, irrigation times should ensure that concrete surface is wet.
Further, in step bl is determined, concrete formulation includes: 390-395 parts of cement, rubble based on its parts by weight of raw materials
1235-1240 parts, 635-640 parts of sand and 180-190 parts of water.
Further, demoulding backfill specifically includes the following steps:
C1: template is dismantled after pouring completion 48 hours in basis, and the concrete removed on basic stand column after disassembly is residual
Slag；
C2: adding overcover in basic stand column exposed parts, then the backfilled with earth in foundation pit, until backfill height and ground
It flushes, is buried basic stand column lower end.
Beneficial effects of the present invention are as follows:
1, it before digging foundation pit, according to foundation pit size after its edge contour marks, is inserted perpendicularly into along every contour line
Several guide piles, every adjacent positioned pilespacing is from reasonable Arrangement, and it is more than pre- one section of foundation pit of digging that every guide pile, which needs to protrude into underground,
Distance, such foundation pit guarantee that guide pile will not fall when digging to bottom, and the square region surrounded when digging foundation pit along guide pile is down
Digging avoids construction error caused by directly digging down with artificial intuition, has standardized construction method, can once dig out satisfaction and hang down
The foundation pit that straight degree requires, meets construction requirement, and be integrally improved construction efficiency.
