Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
Please refer to Fig. 1-5, present embodiment provides a kind of Demolition Construction method of construction wall, comprises the following steps:
Step one, employing static(al) cutting technique cut from top to bottom to body of wall 200; Any one cutting tool can be adopted to cut, such as, with the instrument of cutting knife;
Step 2, when cutting body of wall 200, adopting first crosscut, rear perpendicular step of cutting carries out, wherein during cross-cutting step, adopting the mode of inclined-plane cutting to carry out; Namely, during crosscut, cut direction is set to the cutting of direction, angle of inclination relative to horizontal position, namely inclined-plane cutting, and can be tilted to the left, also can be tilted to the right, and can require to carry out suitable selection according to construction environment; In figure, F is transverse cuts face, i.e. inclined-plane cutting.
Step 3, the step that the wall block 201 after cutting is removed.
The Demolition Construction method of the construction wall 200 of present embodiment, have employed static(al) cutting technique and Demolition Construction is carried out to construction wall 200, reduce the noise cutting and remove during body of wall 200 is constructed and produce, after wall block 201 after cutting is performed and removes step, avoid to cut and remove the contamination by dust such as airborne dust that during body of wall 200 is constructed, body of wall 200 collapses and fragment splashes.Adopt first crosscut, rear perpendicular step of cutting cuts, prevent from formerly erecting the situation blocking cutting tool of cutting, causing in rear crosscut construction; The mode particularly adopting inclined-plane to cut in cross-cutting step is carried out, wall block 201 then after cutting can skid off downwards on body of wall 200, facilitate the effect that the wall block 201 after to cutting removes, wherein, remove in step at wall block 201, in the side that the minimum point on inclined-plane is downward, wall block 201 after cutting can be removed, be specially adapted to removing of lifting.That is, the wall block 201 cut down, after construction wall 200 cutting is decomposed into several little wall blocks 201, removes simultaneously, thus reaches the object of removing construction wall 200 by the present invention.The present invention is applicable to the dismounting of body of wall 200 on the ground, is also applicable to the dismounting of wall by stages in stage construction base pit engineering, owing to having reduction noise, avoids airborne dust etc. to affect the problem of environment pollution, therefore, it is possible to meet the demand for development of green construction.
Please refer to Fig. 3, the Demolition Construction method of the construction wall 200 of present embodiment, before step one, also comprises the step of ruling to the metope of body of wall 200, to cut with by body of wall 200, so that body of wall 200 is divided into several wall blocks 201 along line to body of wall.Wherein, the lines of line are entity lines or virtual lines.Wherein the line of entity lines can adopt ink fountain snap the line or marker pen to rule.The hatched manner of ink fountain snap the line has advantage fast and easily, the position before can reducing to rule or the measurement of distance.Marker pen is scribed ss and can realizes the mode that present embodiment marks entity lines.Wherein, the line of virtual lines can adopt the virtual lines that sharp light-struck mode is rule.Virtual lines have the advantage that can reuse, and laser equipment can be modulated to the lines intersected pre-set and project to body of wall 200, to be mapped on the metope of body of wall 200 by virtual lines.The lines of ruling in present embodiment preferably adopt the mode of ledgement 202 and vertical moulding 203 to rule.Can certainly adopt that to intersect respectively be that the mode of other lines intersected such as 45 degree is rule.First rule and cut again, be convenient to control the overall pulling down engineering time of construction wall 200, be convenient to construct according to plan, and can ensure that the size of each wall block 201 is no more than and lift heavily quantitative limitation.
Please refer to Fig. 4, the Demolition Construction method of the construction wall 200 of present embodiment, the joining being also included in line bores the step of fabrication hole 205, to be cut wall block 201 for starting point and/or terminal by this fabrication hole 205.It has and can cut for starting point with fabrication hole 205, has quick and easy effect, and is convenient to the effect that contraposition scribe line carries out cutting.
Please refer to Fig. 4, the Demolition Construction method of the construction wall 200 of present embodiment, before lifting, is also included in the step of boring hole for hoist 204 in each wall block 201 region, after being connected with hanging device such as crane 400 grade by hole for hoist 204, wall block 201 lifting is removed.The hole for hoist 204 of present embodiment is no less than two, can be odd number, also can be even number.
Please refer to Fig. 5, the Demolition Construction method of the construction wall 200 of present embodiment, be also included in the step of the wherein side setting operation frame 300 of construction wall 200, to facilitate the construction cutting and remove operation.Handling frame 300 adopts monolithic scaffold floor, and it has can the effect of anti-falling stop thing, particularly in subterranean excavation engineering, can directly to drop the adverse effect produced its collision rift sole plate or the structure floor of foundation ditch by effective anti-falling stop thing.In present embodiment, arrange the constuction joint of L rice distance between handling frame 300 and construction wall 200, the distance L of constuction joint can be 0.5 meter or 1 meter etc.
Please refer to Fig. 6, the Demolition Construction method of the construction wall 200 of present embodiment, in step 3, the mode of lifting is adopted to remove the wall block 201 after cutting, with realize from top to bottom wall block 201 is lifted carrying, thus reach the object removed, can certainly remove by setting up the alternate manners such as transport tape.Wherein, adopt hanging device such as crane 400 grade to carry out lifting to wall block 201 in present embodiment to remove, before lifting, first by the hole for hoist 204 of the ropes such as wire rope 402 through wall block 201, then after being connected and fixed with rope 402 by the suspension hook 401 of crane 400, operation crane 400 lifts by crane, thus is removed by wall block 201.Also can be fixing or after directly wall block 201 binding being fixedly connected with by rope 402 by wall block 201 by other net, then sling by the suspension hook 401 of crane 400.Certainly in order to easy lifting, also suspension hook 401 can not be set, and directly adopt rope 402 to fix.Hole for hoist 204 can be connected with crane 400 by rope 402, also by such as holding the reinforcing bar of the U-shape of bending 90 degree again, can insert hole for hoist 204 and being connected with crane.
In present embodiment, construction wall 200 can be concrete wall 200, reinforced concrete wall 200, brick wall body 200, brick joisted body of wall 200 or cob wall body 200, also can be the construction wall 200 of arbitrary structures in other building operations.
The invention is not restricted to above-mentioned detailed description of the invention, all various changes done within the spirit and scope of the present invention, all within protection scope of the present invention.
