In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is used to draw the structural representation of the breast wall apparatus that digs the formula basis for the utility model;
Fig. 2 is drawing the application example schematic diagram that digs in the formula foundation construction for the utility model breast wall apparatus.
Description of reference numerals:
The 11-steel fabric sheet; The 12-concrete; 13-draws and digs the formula basis;
14-fore shaft backplate; The 15-face of land.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not paying the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is used to draw the structural representation of the breast wall apparatus that digs the formula basis for the utility model.As shown in Figure 1, the utility model breast wall apparatus comprises the columns that formed by steel fabric sheet 11 and concrete 12 gluings around steel fabric sheet 11, and the column of formation has hollow structure, hereinafter referred to as hollow column.The outer length of side or the external diameter of hollow column, with design in advance to draw the length of side or the external diameter that dig formula basis 13 identical.
In the technique scheme, optionally, the hollow columnar body by integral forming; Perhaps, the sliceable moulding of hollow column is for example spliced with the glued part that forms of mixed earth respectively by the polylith steel fabric sheet, forms required hollow column.
In order to reach supporting protection effect preferably, can with the wall thickness of hollow column 4cm-6cm, preferred, the wall thickness of hollow column is 5cm.The shape of hollow column and design in advance to draw the shape of digging the formula basis identical, if draw dig the formula basis cross sectional shape for circular or square, then the shape of hollow column also should be circular or square mutually.
Because it is bigger to draw the height that digs the formula basis, in order to improve the convenience of construction, one of the formation that a plurality of hollow columns can be linked to each other is rectangular, and the total length of the hollow column of the formation that links to each other equals or be slightly larger than to draw the overall height of digging the formula basis.Each saves the contour design of hollow column, to improve the convenience of construction.
The utility model breast wall apparatus digs formula foundation outline coupling with drawing of design in advance, in drawing the work progress that digs the formula basis, the utility model breast wall apparatus can be arranged on to be formed drawing digs on the hole wall on formula basis, because the hollow column of breast wall apparatus has soundness and intensity preferably, therefore can effectively prevent to cheat the wall soil body caves in, thereby provide effective security protection for drawing the work progress that digs the formula basis, improved and drawn the working security that digs the formula basis.
Fig. 2 is drawing the application example schematic diagram that digs in the formula foundation construction for the utility model breast wall apparatus.As shown in Figure 2, the utility model breast wall apparatus can form drawing to dig in the formula foundation construction process, digs the hole wall that drawing of formula basis dig pit and carries out the safety supports protection being used to draw.Concrete, the utility model digs the job practices of carrying out the safety supports protection in the formula foundation construction and may further comprise the steps drawing:
Step 1, draw and dig drawing when digging the formula foundation construction segmentation height.Each section is high to be 1m-1.5m, draws the diameter of digging pit and equals to draw the intended diameter of digging formula basis 13 and the design wall thickness sum of breast wall apparatus, and preferred, the wall thickness of breast wall apparatus is 5cm.
Step 2, finish first section high L1 draw dig after, adopt 14 pairs of fore shaft backplates to draw to scrape out draw to dig pit carried out fore shaft.Fore shaft backplate 14 can be assembled into an integral body by several piece, and draws the high part of this section of digging pit and form annular retaining wall zone.Fore shaft backplate 14 can extend to few 1.5m on the face of land 15 by drawing the outer wall of digging pit outside the hole, the length of the backplate of first section high L1 in foundation pit is identical with first section high height.
Step 3, in annular retaining wall zone, arrange one deck ring like steel wire net sheet 11.
Step 4, in annular retaining wall zone concreting 12, concrete around steel fabric sheet 11 gluings be one.For shortening the engineering time, can select the quick-dry type concrete.
Step 5, when concrete 12 reaches form removal intensity, remove fore shaft backplate 14.
Can form first section hollow column by step 1-5.
Next, can adopt the same procedure shown in the step 1-5, continuing forms other hollow columns, for example: adopt method shown in the step 1 to draw and dig second section high L2; Adopt the method shown in the step 2 to draw the part layout fore shaft backplate that digs out, form annular retaining wall zone newly; Adopt the method shown in the step 3 in annular retaining wall zone, to arrange ring like steel wire net sheet; Adopt the method concreting in annular retaining wall zone shown in the step 4; When concrete reaches form removal intensity, adopt the method shown in the step 5 to remove the fore shaft backplate.Formed second section hollow column like this.By that analogy, adopt identical method to form the multistage hollow column, the multistage hollow column by the concrete gluing be one rectangular, equal or be slightly larger than to draw to dig the formula Base Design degree of depth until the final lengths of hollow column, also promptly formed the breast wall apparatus that the utility model provides.
Drawing after the outer wall formation breast wall apparatus of digging pit at the employing said method, can form draw at the cavity of breast wall apparatus and dig the formula basis.Because the hollow column of breast wall apparatus has soundness and intensity preferably, therefore can effectively prevent to cheat the wall soil body and cave in, thereby provide effective security protection for drawing the work progress that digs the formula basis, improved and drawn the safety of digging the formula foundation construction.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model embodiment technical scheme.
