Description

Stir the continuous underground wall construction method of heavy folded double wall
The present invention relates to a kind of continuous underground wall construction method.
At present, the underground continuous job practices of known utilization, at first establish the scope architrave place of diaphragm wall at predetermined structure, dig earlier and establish shallow ridges, after dig downwards and establish zanjon at secondly predetermined paragraph place, the reinforcing cage established with the reinforcing bar structure of transplanting again, or with the PC plate of precasting moulding, but, to dig shallow ridges concrete perfusion behind the implanted reinforced bar cage face, at least after need treating that then the bottom concrete reaches the initial set degree, just must continue the construction of next stage, work progress and treating duration tangible quite labor intensive and man-hour therebetween, when establishing as digging when zanjon, need do the detection of verticality at any time, after making zanjon wall soil, firmly reduce avalanche again, in zanjon, inject stabilizing solution etc., and can influence reinforcing cage structure and concrete bond stress, moreover, use stabilizing solution more to have polluted underground water to reach, sewer, the variation that can't determine in the face of the soil structure layer again again, before construction, do not have when doing one's assignment before the properly complete investigation, then frequent because soil structure in construction period, and puzzlements such as problem that construction is produced can't carry out smoothly and security consideration, even may cause and make and to construct, and force the interruption engineering to be carried out, also in construction, add the noise of generation and the air pollution of the cloud of dust.
Known continuous underground wall construction method remains in following shortcoming:
One, because the formation of known continuous wall, some via as above-mentioned formed interim unit wall body, the continuous wall that forms in succession and organize with continuous placement, so there is no element good, that can join combination between the unit wall body in twos, making in twos, the joint between the unit wall body has the gap, because of can't driving fit, can't reach whole due watertightness of comprehensive metope of continuous wall and requirement of strength.
Two, since as preceding known as described between two unit wall bodies of formation, because of space that can't fluid-tight engagement caused, its slit forms the flow-guiding mouth that seeps water naturally, therefore, the connecting wall that is connected still produces infiltration, causes the danger of constructing and the puzzlement that in the future keeps away body drain water between the operating period.
Three, tradition is inserted behind the reinforcing cage mode of concrete perfusion again in zanjon, by reserving the grouting mouth on the reinforcing cage, behind concrete perfusion of this grouting mouth, treat its concrete setting and form the sample attitude of unit wall body, but the degree of depth is profound because the width of groove is narrow (surpassing more than 10 meters usually), and in being full of the groove of stabilizing solution by the slurry, reinforcing cage pollutes and influences its bond stress except being subject to stabilizing solution, groove internal cause wall soil, silt particle are sneaked in the concrete easily, and influence concrete strength, and then produce and reduce the phenomenon that intensity and quality differ.
Four, known PC plate is after groove is gone in transplanting, utilize the consolidation liquid of hybrid modulation to inject groove, fill the both sides that coat the PC plate, after being solidified, it can form in conjunction with the wall body form, but because no good connect mechanism between the PC plate and only depends on the consolidation liquid combination, in the time of may be because of the hybrid modulation of consolidation liquid, ratio, time error and easily change, thereby cause influencing the globality structural strength.
Five, the continuous wall of tradition is by inserting reinforcing cage in the box cut; operation such as concrete perfusion and forming again; but it is normal because the domain condition is not good; execution control control is bad, and causes the level and smooth program of vertical precision, concrete wall, and problem such as thickness of protection tier deficiency; wherein; except causing wall body cracking and corrosion of steel bar easily, and outside the function of harm retaining wall, also increase the construction burden.
Six, because traditional diaphragm wall is being full of the groove construction of stabilizing solution, and the one-body molded volume that constitutes of reinforcing cage (or PC plate) is too huge, cause except that constructional difficulties, the wall body quality also is difficult to control, therefore, often need be in the wall body inboard of excavation face, diaphragm wall wall coarse or that may chap is decorated in walling in addition, and it not only reduces outside the basement volume space, more needs repeatedly reinforcing construction, increase manpower, man-hour, costs such as material application on foot.
