Description
Technical Field
The utility model relates to a construction engineering ground field, concretely relates to be used for secret diaphragm wall shaped steel to connect and prevent around closely knit device of flow soil bag impact.
Background
The deep foundation pit of open-cut buried tunnel foundation pit, utility tunnel foundation pit, push pipe and shield work well in the existing city construction field often adopts the underground continuous wall to enclose the structural style, and the underground continuous wall is a trench that is excavated with certain degree of depth and width along predetermined position segmentation through dedicated grooving equipment, then puts the steel reinforcement cage in the groove section, and concrete pouring forms continuous steel reinforcement cage concrete wall at last. The joint connection of the successive construction of the underground diaphragm wall adopts the forms of lock catch steel pipes, profile steel joints and the like, the amplitude structure of the underground diaphragm wall with the thickness of 600mm-800mm generally adopts the form of lock catch steel pipe joints, and the amplitude joint of the underground diaphragm wall with the thickness of 1000mm-1200mm adopts the form of profile steel joints.
According to the common method of the section steel joint, in order to prevent the concrete of the underground diaphragm wall of the groove section which is constructed firstly from flowing around to the back of the section steel joint, the groove cleaning difficulty of the groove forming process of the underground diaphragm wall which is constructed later at the joint part of the section steel is caused, and further a larger leakage point is formed at the concrete flowing around part of the foundation pit, so that the safety of the whole foundation pit is endangered when the earthwork of the foundation pit is excavated, the mode of zinc sheet iron and soil packet filling at the back of the section steel is generally adopted, and the gap between the section steel joint and the soil wall of the groove section is blocked. If the filling of the soil bags is relatively uniform, the plugging effect can still meet the requirements, but when the filling bags are manually thrown, because slurry exists in the groove sections, the soil bags are often unevenly stacked to cause the filling of the soil bags to be not compact, so that local concrete flows around the back of the section steel when concrete of the groove sections is poured, the occlusion and disconnection of underground continuous walls of adjacent groove sections are caused to generate 30-100 cm broken joints, and if the broken joints are positioned at the silt bottom layer, when the broken joint part is excavated in a foundation pit, a foundation pit support structure is under the action of underground water, and the part is very easy to generate large seepage accidents with silt. In case the accident takes place, except that can appear gushing water in a large number and gushing sand in the foundation ditch, the facility of ground outside the foundation ditch, building (structure), peripheral pipeline, town road all can take place the large tracts of land subsides, will cause great destruction for the surrounding environment of current foundation ditch, also causes great delay to the construction period of this engineering simultaneously.
