As the improvement of a kind of guide wall of underground continuous wall punching block of the utility model system, described guide wall of underground continuous wall punching block system comprises that a plurality of screw mandrels support, and described screw mandrel supports the diagonal brace that supports and be obliquely installed that comprises horizontally set.
Improvement as a kind of guide wall of underground continuous wall punching block of the utility model system, described screw mandrel supports and comprises screw mandrel, two screw rods that the hand of spiral that is spirally connected with screw mandrel two ends respectively is opposite, the medium position of described screw mandrel is provided with pin hole, and the other end of described screw rod and described U-shaped bayonet lock connect.
Improvement as a kind of guide wall of underground continuous wall punching block of the utility model system, described guide wall of underground continuous wall punching block system comprises that also steel form moves hoisting mechanism, described steel form moves that hoisting mechanism comprises portal frame with door frame crossbeam, the cucurbit of the door frame crossbeam downside that is installed on portal frame, described portal frame has column, and the bottom of described column is provided with road wheel.
As the improvement of a kind of guide wall of underground continuous wall punching block of the utility model system, described road wheel is steel wheel or rubber wheel.
As the improvement of a kind of guide wall of underground continuous wall punching block of the utility model system, described U-shaped being arranged in strengthened a logical beam side relative to template.
The beneficial effects of the utility model are: the punching block system in growing, using the utility model in large foundation ditch guide wall of underground continuous wall work progress, its steel form inboard arranges the grid ribs and strengthens logical beam and kept punching block entire system rigidity and stability, has guaranteed the precision of moulding.The template that the inner screw mandrel that arranges supports both sides is connected to fixing one and template is supported and can regulate easily the screw mandrel support carry out the template installation and removal, reach the effect of integral mold plate, thereby dismounting quickly and easily, effectively save man-hour, reduce the dismounting difficulty, save human cost.Use steel form can recycle for a long time the diaphragm wall construction of guide wall process that approaches with same size or specification, save material cost.

The specific embodiment
Further illustrate the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of guide wall of underground continuous wall punching block system for guide wall of underground continuous wall being carried out the fast pouring construction of the utility model, it comprises two parallel steel forms that are oppositely arranged 10, described steel form 10 inboards are installed with grid ribs 12, the opposite side of grid ribs 12 is connected with strengthens logical beam 13, strengthen logical beam 13 and be provided with U-shaped card 19, supports 15 by screw mandrel between described steel form 10 and connect, the two ends of described screw mandrel support 15 respectively with described U-shaped card 19 pin joints.Punching block system in growing, using the utility model in large foundation ditch guide wall of underground continuous wall work progress, its steel form 10 inboards arrange grid ribs 12 and strengthen logical beam 13 and kept punching block entire system rigidity and stability, have guaranteed the precision of moulding.The inner screw mandrel that arranges supports 15 templates with both sides and is connected to fixing one and steel form is supported and can regulate easily the screw mandrel support carry out the template installation and removal, reach the effect of integral mold plate, thereby dismounting quickly and easily, effectively save man-hour, reduce the dismounting difficulty, save human cost.Use steel form can recycle for a long time the diaphragm wall construction of guide wall process that approaches with same size or specification, save material cost.
More preferably, described guide wall of underground continuous wall punching block system comprises that a plurality of screw mandrels support 15, described screw mandrel support 15 comprise horizontally set support 16 and the diagonal brace 18 that is obliquely installed.Setting supports 16 perpendicular to steel form, can accurately adjust size, guarantees pouring quality, also can shrink fast two distances between steel form, and is for convenience detach.Support 16 and diagonal brace 18 in conjunction with can form the triangle strong construction, thereby the intensity that guarantees template system guarantees the precision of building.
More preferably, described screw mandrel supports 15 and comprises screw mandrel 20, two screw rods 22 that the hand of spiral that is spirally connected with screw mandrel 20 two ends respectively is opposite, and the medium position of described screw mandrel 20 is provided with pin hole 25, the other end of described screw rod 22 and described U-shaped card 19 pin joints.Thereby pin hole 25 can insert pin rotary screw 20 easily, and then makes screw rod 22 synchronous backwards at two ends flexible, realizes easily installing location and dismounting.
More preferably, described guide wall of underground continuous wall punching block system comprises that also steel form moves hoisting mechanism, described steel form moves hoisting mechanism and comprises the portal frame 30 with door frame crossbeam 32, the cucurbit 39 that is installed on portal frame 30 door frame crossbeam 32 downsides, described portal frame 30 has column 33, and the bottom of described column 33 is provided with road wheel 36.Portal frame comprises two Pin portal frames, it comprises that column 33, door frame crossbeam 32, two ends are respectively with column 33 and the affixed Eight characters of door frame crossbeam 32 support 35, realize firmly syndeton by counter brace 37 respectively with between affixed needle beam 34, the two Pin portal frames of two Pin portal frames.Thereby the cucurbit of portal frame crossbeam downside can with described steel form by U-shaped link to connect transport integral mold plate to next station, realize loading and unloading fast, shorten man-hour.The location channel-section steel that the handover process is preset by ground carries out position alignment, thereby realizes contraposition in the situation of release guide rail, realizes accurately installing fast.
More preferably, described road wheel 36 is steel wheel or rubber wheel, is the form that adopts castor, facilitates portal frame to move and transfers the steel form assembly, and the steel form assembly refers to the syndeton between steel form and a pair of steel form and strengthens structure etc.
More preferably, described U-shaped being arranged in strengthened a logical beam side relative to template, is convenient to support with screw mandrel and installs and removes, locates, and also facilitates to be connected with lifting device.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
