Description

Technical Field

[0001] The utility model relates to the technical field of initial rainwater collection at docks, in particular to a collection structure suitable for initial rainwater at bulk cargo docks. Background Art

[0002] When bulk cargo terminals are loading and unloading materials such as coal and ore, dust is easily scattered on the dock. When it rains, the suspended matter in the initial rainwater is relatively high. The relevant specifications for port design also clearly stipulate that the design of old bulk cargo terminals such as coal and ore should collect and treat the initial rainwater separately.

[0003] The initial rainwater collection of a newly built bulk cargo terminal generally adopts the method of setting drainage ditches in the horizontal direction of the terminal, that is, setting drainage ditches in the direction parallel to the terminal beams, setting a certain drainage slope in the direction of the longitudinal beams, and draining water from both sides of the terminal to the middle drainage ditch to collect initial rainwater. However, many existing old bulk cargo terminals do not have rainwater drainage ditches, but only set drainage outlets at intervals at the lower end of the cofferdams on both sides of the terminal bridge deck, and the rainwater is directly discharged into the river or the sea. If it is necessary to collect initial rainwater from these existing old terminals, according to the method of building new terminals, digging drainage ditches on the original terminal surface will damage the structural beams of the terminal. Once the existing structural piles and beams are penetrated, even if they are reinforced, it is difficult to form a stable whole due to the different expansion and contraction deformations of the new and old structures, which poses a hidden danger to the safety of the terminal. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content
