Embodiment 1
[0043] Such as Figure 1-7 As shown, a composite material floating mesh interception system includes main buoy 1, side buoy 2, secondary buoy 3, small buoy 4, cable 5, anchorage 6, ultra-high molecular weight polyethylene nylon cable 7, buffer energy consumption Material 8, buffer energy-dissipating space lattice body 9, concrete inner core 10 and buoy shell 13;
[0044] The main buoy 1 is connected to the two side buoys 2 respectively by two cables 5, a plurality of secondary buoys 3 are arranged at intervals on the cable 5, and a plurality of small buoys 4 are continuously arranged on the cable 5, and the main buoy 1 , side buoys 2, secondary buoys 3, small buoys 4 and cables 5 together form an intercepting net;
[0045] The main buoy 1, the side buoy 2, the secondary buoy 3 and the small buoy 4 are all made of composite materials, including a buoy shell 13 and a concrete inner core 10, and the buoy shell 13 is a solid shell composed of a composite material surface layer bod...
Embodiment 2
[0058] Such as Figure 8 with 9 As shown, this embodiment is basically the same as Embodiment 1, the difference lies in the arrangement of the anchors, and the main buoy 1 and the side buoys 2 respectively adopt the arrangement of three anchors 6 fixed in parallel.
Embodiment 3
[0060] Such as Figure 10 with 11 As shown, this embodiment is basically the same as Embodiment 1, the difference lies in the arrangement of the anchorage,
[0061] The main buoy 1 and the side buoys 2 respectively adopt the arrangement of three anchorages 6 fixed in series.

Abstract
The invention discloses a composite material floating type net-shaped interception system and a construction method. A primary buoy, a lateral buoy, a secondary buoy and a small buoy are manufactured through a vacuum infusion one-time forming technology by means of fibers and resin and are connected through cables which are adjacent to one another and connected, then the relative positions of the buoys are determined through ultra-high-molecular-weight polyethylene nylon cables via anchors, the buoys are fixed to a riverbed, a pair of floating type net-shaped interception systems are symmetrically arranged on the two sides of a pier so that ships can be interrupted or poked to steer, and the systems serve as the first defensive line for buffering collisions. When the composite material floating type net-shaped interception system is used as a composite material floating body anti-collision device, if small ships collide with a bridge tower, high deformation capacity is achieved due to the fact that section shells of the buoys are made of elastic composite materials, and the buoys can be automatically restored and not damaged after compression.
Description
technical field [0001] The invention relates to an anti-collision structure on water, which is a low-cost elastic and corrosion-resistant anti-collision device made of composite materials, specifically, it is suitable for piers and caps of various bridges, etc. on water (ocean) A composite material bridge anti-collision device for building to avoid ship (ice floes) collision disasters. Background technique [0002] Ship collision accidents have been happening all over the world. With the rapid development of the transportation industry, the number of large bridges crossing navigable rivers, port areas and straits is increasing; at the same time, the number of ships on the waterway is also increasing and tends to Due to the large scale, the contradiction between bridges and navigable ships has become increasingly prominent. The problem of bridge ship collision prevention is gradually getting great attention from relevant shipping management, planning and design departments. ...
