Description
Technical Field
The invention relates to a steel sheet pile connection mode, in particular to a welding type steel sheet pile corner water stop construction method.
Background
The steel sheet pile is used as a building enclosure and is used as a soil retaining wall, a water retaining wall and a sand retaining wall during foundation pit excavation, bridge cofferdam construction, large-scale pipeline laying and temporary ditch excavation. The steel sheet pile is high-strength steel with locking mouth, and is engaged with locking mouth to form closed steel sheet pile wall, and can be used for retaining soil and partial water-retaining engineering, and is suitable for preventing seepage in water and under the ground water level. Fig. 1 is a schematic view of a conventional steel sheet pile corner connection structure. Because the lock openings are tightly jointed, the problem that the joint parts are easy to be split when the supporting impervious wall is constructed by other methods is solved, and the large seepage of underground water can be prevented. However, when the steel sheet pile is used for constructing four corner positions of a foundation pit, the locking notch cannot be a right-angle corner, and the transition needs to be slowly carried out according to a curve, so that the locking notch is occluded with a gap, tightness is not achieved, and water leakage and water seepage are easy to occur. In addition, the maximum difficulty of the locking notch engagement is caused by the accumulated error of the new and old degree and the construction gradient of the steel sheet pile, and water leakage caused by the inaccurate locking notch engagement is also easily caused.
Chinese patent CN108130956A discloses a waterproof node structure of a corner wall of an underground prefabricated laminated wall panel and a construction method thereof in 2018, 6.8.8.a bottom plate, a first double-sided prefabricated wall panel and a second double-sided prefabricated wall panel are perpendicular to each other, and an end of the first double-sided prefabricated wall panel is correspondingly connected with a side of the second double-sided prefabricated wall panel. However, the assembled industrialized underground building formed by the double-sided laminated wall boards has the difficulty of wasting labor and materials, is only suitable for the outer walls of structures such as basements, semi-basements, underground garages and the like which adopt the double-sided laminated wall boards, and has no wide application value.
Therefore, the known steel sheet pile corner water stopping method has various inconveniences and problems.
