Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As Fig. 1, shown in 2, for diaphragm wall shutoff stopping means of the present utility model, it comprises the joint 10 and encapsulation column 20 that are positioned at diaphragm wall unit end face, this joint 10 is consistent with the I-shaped steel joint structure of existing diaphragm wall end face, it specifically has the wing plate 12 that two are stretched out diaphragm wall unit end face, and the web 11 extended along diaphragm wall cell width direction between two wing plates 12, certainly, in the utility model, as long as under guaranteeing that two wing plates 12 have the prerequisite of enough flexural strengths at diaphragm wall width, also can be that above-mentioned web 11 is not set, as long as guarantee that wing plate 12 can stretch out to coordinate with encapsulation column 20 and adjacent continuous wall connector 10 by diaphragm wall unit end face.Encapsulation column 20 is the structure of a hollow, it specifically comprises baffle plate 21 and force bearing plate 22, baffle plate 21 is covered in outside the end face of two wing plates 12, force bearing plate 22 is positioned at the outside of baffle plate 21, and force bearing plate 22 is set to the shape that cross section is outer convex, force bearing plate 22 both sides are fixedly welded on the both sides of baffle plate 21 respectively, thus, this force bearing plate 22 and baffle plate 21 surround the column structure of a hollow, baffle plate 21 is welded with two plates 23 vertical with baffle plate 21 away from the surface (namely for the surface of capping two wing plate 12) of force bearing plate 22, this two plate 23 lays respectively at the inner side of two wing plates 12.
When having carried out construction of diaphragm wall, first the reinforcing cage of diaphragm wall unit is set up, then encapsulation column 20 lifts in the groove to the joint 10 of diaphragm wall unit end face by zero hanging device, when inserting encapsulation column 20, guarantee that the bearing of trend encapsulating column 20 is consistent with short transverse, two plates 23 of encapsulation column 20 are made to lay respectively at the inner side of joint 10 liang of wing plates 12, and, that tries one's best guarantees that corresponding plate 23 is identical with the spacing of wing plate 12, the outside of the lucky capping joint 10 liang of wing plates 12 of baffle plate 21, afterwards, at the inner concrete perfusion of the reinforcing cage of diaphragm wall unit, until concrete setting and after reaching some strength, hanging device is utilized encapsulation column 20 entirety to be extracted, afterwards, carrying out the excavation of follow-up diaphragm wall unit groove section, due to when excavating follow-up groove section, need to utilize rig the soil body bottom encapsulation column 20 or other structures to be broken up, just can carry out the excavation of follow-up groove section, therefore, in order to accelerate the speed of application of rig and be beneficial to block stamp impact construction, need to reserve enough clear space in follow-up groove section joint, to facilitate lower hammer, therefore, the both sides of above-mentioned encapsulation column 20 have the part protruding from joint 10 both sides respectively, the part of this protrusion can be weld other steel work at the side of above-mentioned baffle plate 21 and force bearing plate 22, also can be as shown in fig. 1, increase the span of baffle plate 21 and force bearing plate 22 arc, the width of encapsulation column 20 is made to be greater than the width of joint 10.
Diaphragm wall shutoff stopping means of the present utility model is when carrying out construction of diaphragm wall, substitute existing sand bag, monolithic is embedded into the end of diaphragm wall unit, and the construction for two diaphragm wall unit joints provides convenient, overcomes the defect that efficiency of construction that stacking sand bag causes is low, long in time limit; , concretely when effectively preventing filling concrete to stream meanwhile, can reuse in construction of diaphragm wall process; In addition, after encapsulation column 20 is extracted, the clear space reserved is large, decreases operation and the construction volume of the construction of follow-up diaphragm wall unit, has saved construction cost.
According to the needs of shutoff and the structure of joint 10, encapsulate column 20 when considering construction simultaneously and need the end depending on joint 10, therefore, adopt and to arrange two near the side of wing plate 12 perpendicular to the plate 23 of baffle plate 21 at baffle plate 21, and consider bulk strength, between two plates 23, arrange a gripper shoe 24, the both sides of this gripper shoe 24 are welded on two plates 23 respectively, make the connected structure formation one of baffle plate 21 near joint 10 side coordinate the i iron of grafting with joint 10.
In plugging construction process, in order to improve the steadiness that encapsulation column 20 is combined with joint 10, especially avoid encapsulating situation about being separated with joint 10 in the interference by soil structures bottom column 20, the utility model arranges an insertion section 25 in the bottom of encapsulation column 20, this insertion section 25 for being inserted in the soil body at the bottom of diaphragm wall unit groove, the taper that insertion section 25 is big up and small down.
When reality uses, consider that force bearing plate 22 may bear larger pressure, therefore, can weld between baffle plate 21 and force bearing plate 22 and strengthen gusset.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
