In order to realize purpose of the present invention, the technical scheme of being taked is: a kind of ultra-deep underground continuous wall connector, comprise an I-shaped cross-section shaped steel 2, first phase groove section reinforcing cage 1 is welded on an end of described I-shaped cross-section shaped steel 2, second phase groove section reinforcing cage 3 inserts the other end of described I-shaped cross-section shaped steel 2, and described the second stage of groove section reinforcing cage 3 tops are provided with broken line shape end socket reinforcing bar 4.
When described I-shaped cross-section shaped steel 2 was constructed in first phase groove section, the end was surrounded by band iron 5 and only starches iron sheet 6.
Described I-shaped cross-section shaped steel 2 insertion groove section baseplanes, the overall height of I-shaped cross-section shaped steel is greater than the degree of depth of groove section.
The second phase bending angle of groove section reinforcing cage top end socket reinforcing bar is determined according to field lofting.The length of the broken line length of side 7,8 on the described end socket muscle 4 top length of sides and both sides is determined by field lofting.
This I-shaped cross-section shaped steel joint will forever be imbedded in the soil as the part of diaphragm wall in case after construction finishes, do not need to resemble and extract fore shaft pipe or the joint case.This kind joint form does not have the muscle zone, belongs to rigid joint.Adopt the diaphragm wall good integrity of this kind joint.Because blank area is the I-shaped shape, has increased osmosis path of underground water, sealing performance is good.Be applicable to the construction of the ultra-deep underground continuous wall that stressed and sealing is had relatively high expectations.
Because the factor of topping; the reinforcing cage width likens little to well width; first phase groove section concrete is built should adopt an effective measure in the process and is guaranteed that concrete streams to the second stage of groove section, therefore, adopts in shaped steel end, I-shaped cross-section, first phase groove section two ends that band iron is fixing only to be starched iron sheet and prevent that concrete from streaming.
The certain distance in shaped steel insertion groove section baseplane, I-shaped cross-section, purpose are in order to prevent that first phase groove section concrete from streaming from the bottom of groove section, to enter in the second stage of groove section, thereby influence the trenching construction of the second stage of groove section.
Needs because of various engineerings, the size of foundation ditch, shape are different, the shape of possible foundation ditch is the polygon of rule, also may be have radian irregularly shaped, because the second stage of groove section reinforcing cage top is provided with the end socket reinforcing bar of broken line shape, and bending angle is determined according to field lofting, can make and form linear connection or non-linear connection between each wall section.Thereby make the scope of application of this joint wider, be applicable to the foundation ditch of different shape.
Said method has been exempted the construction stage and has been pulled out the process of fore shaft pipe or joint case, has reduced difficulty of construction, and simultaneously, construction quality is guaranteed, and this joint has increased structural integrity and the antiseepage reliability that the groove section of diaphragm wall connects simultaneously.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples and application construction method.
Fig. 1 sectional drawing that to be I-shaped cross-section of the present invention shaped steel be connected with the second stage of groove section reinforcing cage with first phase groove section reinforcing cage.
Fig. 2 is the partial enlarged drawing of the present invention's second phase groove section reinforcing cage top end socket muscle.
Fig. 3 is the schematic diagram at the bottom of the shaped steel insertion groove of I-shaped cross-section of the present invention.
The specific embodiment
Adopt the diaphragm wall of I-shaped cross-section shaped steel joint generally to divide first phase groove section and the second stage of groove section, first phase groove section two ends Welder's shaped sections shaped steel 2 is as groove section joint, behind the first phase groove section trenching construction, after reinforcing cage 1 and I-shaped cross-section shaped steel 2 are divided into installation, the son that rockfills next time between I-shaped cross-section shaped steel 2 and slotted eye nose end occurs streaming when preventing concreting and enters I-shaped cross-section shaped steel 2 outsides.After the second phase groove grooving, before dividing into reinforcing cage 1, must butt joint do special the processing, should increase the number of times of brush wall, adopt special spader to remove in case of necessity, as shown in Figure 1.
Behind the whole hole of second phase groove, adopt the segmentation from top to bottom of steel wire brush to scrub first phase groove I-shaped cross-section shaped steel 2 joints.Steel wire brush own wt is lighter, and available bolt is fixed in the bucket body of grab bucket or transfers extension with mobile crane, utilizes its bigger deadweight to make the steel wire brush be close to I-shaped cross-section shaped steel web, thereby can better scrub it.Substantially be not with spare on the brush drill bit, the alluvial of bottom land mud no longer increases.
Because the factor of topping; reinforcing cage 1 width likens little to well width; first phase groove section concrete is built should adopt an effective measure in the process and is guaranteed that concrete streams to the second stage of groove section; therefore; adopt in shaped steel end, I-shaped cross-section, first phase groove section two ends that band iron 5 is fixing only to be starched iron sheet 6 and prevent that concrete from streaming, as shown in Figure 2.
