Abstract
The utility model relates to an underwater bearing platform type shore protection facility. The underwater bearing platform type shore protection facility is characterized in that legs are fixed by the aid of underwater concrete (steel pipe) piles, a concrete bearing platform is used as a foundation for leg grooves and rock-mounted leg protectors instead of a riverbed, accordingly, a base plane consisting of traditional leg grooves, a low-water platform and slope connecting rocks is changed, effectiveness of sections of the underwater leg protectors is kept by means of controlling longitudinal down-cutting of a near-shore riverbed, lateral erosion of water flow to shore bases is controlled, and the purpose that the shore bases of a shore collapse section can be continuously and permanently protected without changing the river regime or affecting stability of a beach strand of an embankment on an opposite shore, a flood control condition and navigation, control and guidance for an existing navigation channel is achieved.
Description
Technical field the utility model relates to a kind of croy of bearing platform type under water, belongs to the bank protection work technical field of construction of hydraulic engineering.
In the background technology hydraulic engineering, the collapse on the bank management measure is that the boundary is divided into bank protection and solid two aspects of pin with the design low water level generally.Promptly design the above enforcement of low water level slope protection works waterborne, implement spats engineering under water below the design low water level.To the regulation of collapse on the bank generally is to be main with spats under water, and bank protection waterborne is auxilliary.The common scheme of spats under water has groynes or rock head spats, jackstone (pillow), gabion spats, various types of mattress sinking spats, long sand filling pipe bag spats etc.There is the problem of following 4 aspects respectively in these constructure scheme: 1, groynes or rock head spats have changed offshore water flow structure and fluidised form; Dyke and existing navigation channel are unfavorable in the opposite bank, have run counter to that principle that left and right banks is taken into account in the dredging waterway and Coordination Treatment are controlled flood well, the requirement of the relation of aspect such as water drainage, shipping, irrigation, water supply, generating and environmental protection; 2, underwater dumped rockfill (pillow), gabion can not change its geological conditions, owing to the Yi Chongxing of riverbed substrate, have just increased the cushion coat of continuous sinking of one deck meeting and loss attenuation, are not suitable for and wash away violent section; 3, various types of mattress sinking spats only adapt under water the gradient and delay in 1: 2.0 and the little section of river-bed deformation, and incompatibility complex-terrain and existing piece stone are thrown the section of protecting; 4, long sand filling pipe bag spats is to build sandbag dam and suitable domatic to rising, and hydraulic reclamation silt is full to becoming silted up in collapsing nest then, is applicable to that nest collapses, and is not suitable for the bar shaped collapse on the bank.The essence of building the sandbag dam is with Sha Haipo, rock head spats, has changed offshore water flow structure and fluidised form, constriction the navigation channel, damage when run-down when sand filling pipe bag, the sandbag dam can subside, collapse on the bank will take place once more.
Summary of the invention the utility model relates to a kind of croy of bearing platform type under water; Utilize the solid pin of underwater concrete (steel pipe) pile foundation; Utilize concrete bearing platform to replace the basis of riverbed as pin groove and enrockment spats; Changing traditional pin groove, low water platform, to connect the basal plane of sloping stone, the vertical incision through control offshore riverbed reaches and keeps the validity of spats section under water, and then the lateral corrasion of controlled water flow opposite bank pin.
The technical scheme of the utility model is: build the pin groove by laying bricks or stones being higher than on the cushion cap of design on the low water level, the low water platform with connect sloping stone.
The beneficial effect of the utility model is, do not change the river gesture, and stable navigation and the control with flood control situation and existing navigation channel of beach strand that does not influence the opposite bank dyke led, and can continue permanent protection collapse on the bank section bank pin and stablize.
Description of drawings
Fig. 1 is bearing platform type croy schematic cross-sectional view under water.
Fig. 2 is bearing platform type croy layout sketch map under water.
Among Fig. 1 and Fig. 2,1-pin groove, 2-low water platform, the 3-spats connects sloping stone, 4-cushion cap, 5-pile foundation, 6-fender pile (pin, the end) stone, 7-riverbed, 8-slope protection works waterborne.
Specific embodiment the present invention can construct as follows:
(1), makes a call to 2～3 rows and safeguard the anti-skid pile under water that bold shore is stable according to underwater topography and the bank slope form and the focused protection scope at scene;
(2) the pile foundation medial and lateral are all by 1: 1.75～1: 2.5 throw, rockfill (pillow) or long sand filling pipe bag fender pile, spats, river bottom protection;
(3) on pile foundation, build cushion cap, the cushion cap elevation of top surface is higher than local design low water level 0.2～0.3m;
(4) build the pin groove by laying bricks or stones by 1.0 * 1.0m on the cushion cap;
(5) build the low water platform on the cushion cap by laying bricks or stones, the low water platform height is concordant with the pin groove, builds spats by laying bricks or stones by 1: 1.75 and connects sloping stone.
Concrete construction process: underwater concrete (steel pipe) pile foundation → throw, fill out fender pile stone (pillow) → build cushion cap → build by laying bricks or stones pin groove → build low water platform → spats by laying bricks or stones to connect sloping stone.
Claims (3)
1. a bearing platform type croy under water is characterized in that utilizing concrete bearing platform to replace the basis of riverbed as pin groove and enrockment spats, to change traditional pin groove, low water platform, to connect the basal plane of sloping stone.
2. the croy of bearing platform type under water according to claim 1 is characterized in that on cushion cap, building by laying bricks or stones the pin groove.
3. the croy of bearing platform type under water according to claim 1 is characterized in that building the low water platform on the cushion cap by laying bricks or stones, builds spats by laying bricks or stones and connects sloping stone.
