The invention discloses a guide device for guiding a cobbly soil foundation steel sheet pile to sink and a using method. The upper portion of a positioning section (2) is connected with the steel sheet pile (4) through pins (3), and the lower portion of the positioning section (2) is connected with front guide cutting slices (1) through front guide cutting slice rotation shafts (5); the positioning section (2) is in a U shape according to the cross section shape of the steel sheet pile; the end of each front guide cutting slice is provided with a rotary wheel (6), the rotary wheel (6) is internally provided with an axle (7), and the outer side of the rotary wheel (6) is provided with a rotary wheel protection plate (8); and the axles (7) are connected with the front guide cutting slices (1) through axle connection plates (10), and limiting devices (13) are arranged between the front guide cutting slices (1) and the positioning section. The using method comprises the steps that 1, the guide device is connected with the steel sheet pile (4) through pins (3); 2, in the steel sheet pile (4) hammering sinking process, sinking is conducted according to the hammering sinking technical standard of the steel sheet pile which is not provided with the guide device; and 3, when concrete engineering construction is completed, and the steel sheet pile (4) is pulled out, the guide device is pulled out together with the steel sheet pile (4).
Description
technical field [0001] The invention relates to the field of technical control when steel sheet pile cofferdams are used for cofferdam construction on pebble soil foundations. Background technique [0002] Steel sheet pile cofferdam is a commonly used construction technology in bridge foundation construction. However, for the steel sheet pile cofferdam construction at the present stage, hammering is mainly used to sink the steel sheet pile, which requires that there should be no pebbles and other objects in the sinking part of the steel sheet pile. Because in the current stage of hammering steel sheet pile construction, the lower part of the steel sheet pile does not have any guiding equipment, and the upper part of the steel sheet pile directly cuts the soil and sinks through the hammering action of the upper part. If objects such as pebbles are encountered, due to the high rigidity of the steel sheet pile itself, it cannot be effectively avoided, and the steel sheet pile ...
