A combined ship lock structure

Abstract

A combined type ship lock structure comprises an integrated structure, connecting pieces and sheet piles. The integrated structure is composed of a lock wall and a flat-bottom-shaped bottom plate. The elevation of the top of each sheet pile is between the original ground elevation and the elevation of the top of the lock wall, the elevation of the bottom of each sheet pile is smaller than or equal to the elevation of a foundation surface, and the elevation of the top face of backfill is smaller than or equal to the elevation of the top of the lock wall. During excavation, lateral bracings are adopted, and a built ship lock is very close to the combined type ship lock. Before construction, the sheet piles, the lateral bracings and the connecting pieces are prefabricated. The connecting pieces are fixed to the sheet piles to connect the sheet piles with the integrated structure, then, the bottom plate is constructed, and finally, the lock wall is constructed. By means of the combined type ship lock structure, the amount of reinforced concrete can be reduced, the stress of the integrated structure can also be improved so that the combined type ship lock structure can meet the requirement of higher filling behind a wall better, the excavated volume of earthwork can also be reduced, and a series of problems caused by stacking of abandoned soil can be avoided. The combined type ship lock structure can expand new study fields for design and type selection of building near ship lock structures.

Description

Technical field [0001] The present invention relates to the technical field of ship lock engineering, and more specifically, is a ship lock structure to be built close to the position of the built ship lock. Background technique [0002] The ship lock is a hydraulic structure set up to overcome the concentrated water level difference on the channel, and plays a pivotal role in the water conservancy and transportation industry. The monolithic ship lock structure is a trough-shaped structure connected by the two sides of the lock wall and the bottom plate, also known as a "U"-shaped structure. The integral ship lock structure can be divided into two types: flat bottom plate and reverse arch bottom plate. The flat bottom monolithic ship lock structure has the advantages of good integrity, strong impermeability, relatively uniform foundation reaction force distribution, and relatively low requirements for foundation bearing capacity, but when the width of the lock chamber is large a...

Problems solved by technology

For this reason, various measures have been proposed, such as row pile support, rock-socketed double-row support piles, etc. when excavating and constructing adjacent ship locks (see Pan Xuanhe's master's thesis of Changsha University of Science and Technology in 2010 "Foundation with row pile support structure The impact of excavation of pits on adjacent ship locks", Lingwei Master Thesis of Changsha University of Science and Technology in 2013 "Application and numerical analysis of rock-socketed double-row support piles in deep foundation pit engineering adjacent to ship locks") Although the above methods will have some impact on engineering practice Good effect and guiding significance, but when the location of the adjacent ship lock is very close to the existing ship lock (the distance between the axis of the lock chamber is less than 100m), the above methods may not be implemented in engineering practice
