Problems solved by technology
[0003] During the construction of steel sheet piles in muddy clay cofferdams, whether the positioning and guidance of the steel sheet piles is good or not will directly affect the waterproof sealing effect between the steel sheet piles. Poor waterproof sealing will lead to a large amount of waterproofing in the later stage. Sealing operation is not only time-consuming but also prolongs the construction period, resulting in increased construction costs

The invention discloses a steel sheet pile inserting and driving orienting device for a mucky clay geological cofferdam. The device comprises an orienting coaming with an opening at one side, a front steel sheet pile positioning buckle and a rear steel sheet pile positioning buckle, wherein the front steel sheet pile positioning buckle and the rear steel sheet pile positioning buckle are fixed to the orienting coaming. The steel sheet pile inserting and driving orienting device is a finished product manufactured in advance in a factory or is manufactured by welding iron plates on site after being adjusted according to site construction requirements, and front and rear steel sheet piles can be fixed and guided through the buckles so as to avoid waterproof sealing failure caused by position deviation of the steel sheet piles in the inserting and driving process. The limiting coaming comprises a front limiting plate used for positioning the front steel sheet pile, a rear limiting plate used for positioning the rear steel sheet pile, and a middle limiting plate used for connecting the front limiting plate and the rear limiting plate. The distance between the inner sides of the front limiting plate and the rear limiting plate is equal to the thickness of the front steel sheet pile and the rear steel sheet pile after the front steel sheet pile and the rear steel sheet pile are combined in an inserted manner. The device has the beneficial technical effects of a reliable and durable structure, convenience in construction and capability of being recycled for multiple times.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to the construction of cofferdams in water conservancy projects, and in particular to a device for inserting and driving steel sheet piles and a construction method for geological cofferdams in muddy clay. Background technique [0002] Water conservancy projects are related to the production and life of residents in various places. In common waterwork operations, the decisive factors for the success and safety of waterwork operations are how to build reasonable underwater temporary structures and reasonable construction plans. Steel sheet piles are characterized by their high strength. , good waterproof, reusable, not limited by the shape of the cofferdam and other characteristics, it is widely used in the construction of deep water foundation cofferdam. The construction quality of the steel sheet pile plays an absolute role in the quality of the cofferdam. [0003] During t...
