H, lift and broken.
Described new and old subway station connectivity part diaphragm wall and side wall restructuring bankrupt, wherein, in the step B, bore lifting
Hole carries out the break flour being ground with using cooling water cooling during lacing hole.
Described new and old subway station connectivity part diaphragm wall and side wall restructuring bankrupt, wherein, in the step G, pass through liquid
Diamond rope of the pressure motor driving with diamond bead operates around cut wall, so as to be ground cut wall, production
Raw abrasive dust and the cooled water of heat are taken away, and are finally reached the purpose of separation concrete.
Described new and old subway station connectivity part diaphragm wall and side wall restructuring bankrupt, wherein, in the step H, it will split
While blocking concrete block is vertically suspended in midair with A seating electric block, with hoist engine transverse translation concrete block and outward
Haul out 80-150 cm；Hang again to track flat car；Then level is transported to exit；Finally go to ground using truck crane
Crushed on face.
Beneficial effect：By the method for the present invention, it is continuous with building up station can safely and efficiently to abolish new subway station
Wall and side wall, the duration can be shortened by carrying out underground engineering construction using the method for the present invention, and and can significantly reduces construction and made an uproar
Sound, reduce dust, it is ensured that construction safety, existing structure safety, operated subway and passenger safety.

Embodiment
The present invention provides a kind of new and old subway station connectivity part diaphragm wall and side wall restructuring bankrupt, to make the mesh of the present invention
, technical scheme and effect it is clearer, clear and definite, the present invention is described in more detail below.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
A kind of new and old subway station connectivity part diaphram wall and side wall provided by the present invention abolish method, and it includes step
Suddenly：
S1, determine to cut new and old subway station connectivity part diaphram wall and side wall position.
As depicted in figs. 1 and 2, according to construction drawing field lofting, blocking unit is planned（Piecemeal wall）, cutting circuit and
Cutting section position, wherein 10 be new and old subway station connectivity part, 110 be old subway station（Building up station）Side wall, 120 be new
Subway station（New subway station）Side wall.Wherein, each blocking unit size is 3.0m 3.0m.Local wall can suitably subtract
Small blocking unit size, dividing condition are as shown in Figure 3.
S2, bore hole for hoist and lacing hole.
According to Hoisting Position and cutting circuit, hole for hoist and lacing hole are bored using diamond water drilling respectively.Wherein, Mei Yifen
4 drift angles of module unit bore hole for hoist and lacing hole using diamond water drilling, and hole for hoist and lacing hole aperture are 200mm（Such as
Shown in Fig. 4, wherein 20 be lacing hole）.Remaining cut-off rule uses diamond-wire saw cut.Diaphram wall and side wall overlapping portion
Point, block size is identical, cuts simultaneously.
S3, installation stator wheel and rope saw equipment.
Specifically available chemical bolt static line saws main foot stool and auxiliary stand.Stator wheel is divided into driving wheel and driven
Wheel.
S4, installation diamond rope.
According to fixed cutting section, diamond rope is wrapped in driving wheel, on auxiliary wheel in sequence, and penetrate
Lacing hole.
S5, wear hoisting rope.
Liftable rope penetrates hole for hoist, and wearing hoisting rope ensures dismantling concrete energy safty hoisting.
S6, linked operation system and installation safety guide rail.
According to field condition, water, the electrically and mechanically associated pipe such as equipment and safety protection equipment are connected.
S7, in sequence wall cutting.
Driving wheel lifting tension force is adjusted, ensures that diamond rope is suitably tightened, cooling water supply, restarts driving actively
Wheel, drive diamond-wire to recover and turn cutting.
It is overall to remove（Cutting）To cut successively from top to bottom, each layer of piecemeal is carried out order, specific as Fig. 3 orders are torn open
Remove, first 1-1,1-2,1-3 ..., 2-1,2-2,2-3 ..., finally to 3-3,3-4,3-5.
S8, lifting and broken.
After the completion of cutting, concrete component is lifted into the place specified and crushed by entirety, and clears out job site in time.
Further, in the step S2, water cooling is used in boring procedure, and carry out the break flour being ground.Hole
Position is controlled using cross setting-out method and perforate controller, and water drilling corning machine must be fixedly secured on metope before drilling.
Further, in the step S7, diamond rope saw cuts through hydraulic motor high-speed driving and carries diamond string
The steel wire cable of pearl operates around cut concrete, and in the presence of certain stretching force, high-speed grinding is cut concrete, production
Raw abrasive dust and the cooled water of heat are taken away, and are finally reached the purpose of separation concrete.
Further, in the step S8, while blocking concrete block being split and vertically suspended in midair with A seating electric block,
80-150 cm are outward hauled out with hoist engine transverse translation concrete block;(track and flat board are hung to track flat car again
Car can use shaped steel to make by oneself);Then level, which is transported to, hangs exit;Finally gone on ground and crushed using truck crane.
In summary, by the method for the present invention, it is continuous with building up station new subway station can safely and efficiently to be abolished
Wall and side wall, the duration can be shortened by carrying out underground engineering construction using the method for the present invention, and and can significantly reduces construction and made an uproar
Sound, reduce dust, it is ensured that construction safety, existing structure safety, operated subway and passenger safety.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can
To be improved or converted according to the above description, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Protect scope.
