Title:
CONSTRUCTION METHOD FOR REMODELING AND EXTENDING SHIP LOCK IN SITU
Document Type and Number:
WIPO Patent Application WO/2024/099477
Kind Code:
A1
Abstract:
Provided in the present invention is a construction method for remodeling and extending a ship lock in situ. A flood gate in a built ship-lock upper lock head section is used as a water-retaining cofferdam during a construction period; in terms of plane arrangement, starting from a target cutting-off face located in a built ship lock chamber section to downstream, the remaining part of a built ship lock is cut off, and a new ship lock is constructed; and in terms of cross-section arrangement, a shore-side pier structure between the built ship-lock upper lock head section and a new ship-lock upper lock head section is cut off to a first preset elevation, a first water-retaining and impervious line and a second water-retaining and impervious line are added, and an impervious key wall is constructed, and an upper guide wall section of the built ship lock and the built ship-lock upper lock head section are remodeled, and a third water-retaining and impervious line is added. By using an original water-retaining line building as a water-retaining line during the construction period and by moving a permanent water-retaining line of a junction downwards, it is ensured that the normal operation of a built junction is not affected during the construction period; and the habitual thinking of it being necessary to construct a large-scale earth-rockfill cofferdam project upstream to remodel existing water-retaining line buildings is skillfully avoided, thereby ensuring safety during a project remodeling construction period and greatly saving on project costs.
