Abstract
The utility model relates to a nut block body protective face structure which comprises a protective face structure which is formed by connecting nut block bodies one by one. The protective face structure is characterized in that the bottoms of the nut block bodies are provided with clamping grooves and convex feet, the clamping grooves and the convex feet of the adjacent nut block bodies are mutually matched, the bottom of the protective face structure is provided with a bottom plate which is integrally cast with the nut block bodies, and drain holes are arranged on the bottom plate. The utility model adopts the optimal proposal that the bottoms of two side surfaces of the nut block bodies are provided with the clamping grooves, and the bottoms of two corresponding side surfaces are provided with the convex feet. The utility model has the advantages that the utility model provides an economic, convenient, safe and reliable novel nut block body protective face structure, enlarges the application range of the nut block bodies, simplifies construction processes, reduces construction investment and solves the problem that the nut block bodies are easy to suck and destroy.
Description
Technical field
The utility model relates to a kind of protecting slope of dam ground surface protection structure that is applicable to engineerings such as dyke, reservoir dam, is specifically related to a kind of nut block ground surface protection structure.
Background technology
The artificial block masks of employing such as the dyke at present domestic and international many stormy waves bigger area, particularly coastal area, reservoir embankment carry out the protection of side slope.No matter when the conventional artificial block of installation is turned round king's block or is turned round worker's block, nut block and barrier board mask, its underpart generally need be done one deck laid dry (irritate and build) piece stone or concrete cushion earlier, working procedure is more, investment is bigger, especially in the area that lacks building stones, the imbalance between supply and demand of building stones is also very outstanding.
The plain nut block has the good unrestrained effect and easy for installation that disappears, to compare cost lower with other artificial block (comprising barrier board), comparing unit area building cost with filling building block stone mask is more or less the same, but adopt nut block mask to compare filling building block stone mask and can more effectively reduce wave run-up, reduce dike (dam) crest level, taking all factors into consideration also has remarkable advantages on cost, so the nut block has obtained more application at present.Consider that at present for facility is installed, the general substance of nut block is little, than turning round king's block, turn round worker's block and four jiaos of cavity blocks are all much smaller, when stormy waves is big the nut block have by the wave sucking-off destroy may.
The utility model content
The purpose of this utility model has provided a kind of nut block ground surface protection structure, has solved the technical problem that traditional nut block ground surface protection structure is easily destroyed by the wave sucking-off when stormy waves is big.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of nut block ground surface protection structure, comprise the ground surface protection structure that connects and composes one by one by the nut block, it is characterized in that: the bottom of described nut block is provided with draw-in groove and protruding pin, the draw-in groove of adjacent nut block and protruding pin match, the bottom of ground surface protection structure is provided with the base plate integrated poured with the nut block, and base plate is provided with drain hole.
Wherein two side bottom of described nut block are provided with draw-in groove, and two side bottom relative with it are provided with protruding pin.
The beneficial effects of the utility model are: a kind of economy, convenience, safe and reliable new type nut block ground surface protection structure are provided, have enlarged the scope of application of nut block, simplified working procedure and reduce construction investment, solved the problem that the easy sucking-off of nut block destroys.
Description of drawings
Fig. 1 is the structural representation of nut block;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is a nut block ground surface protection structure schematic diagram;
Fig. 4 is the side sectional view of nut block ground surface protection structure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of nut block ground surface protection structure, as shown in drawings, in order to enlarge the scope of application of nut block, simplify working procedure, reduce construction investment, solve the nut block and be prone to the problem that sucking-off destroys, stretch out protruding pin 1 on the both sides, bottom of plain nut block, establish draw-in groove 2 on adjacent both sides simultaneously.The draw-in groove 2 of next nut block is pressed on the last protruding pin 1 during construction and installation, presses one by one to form from a side to link.Can change the situation that former nut block is independently resisted ripple suction after linking, become whole ground surface protection structure unit associations opposing ripple suction, greatly change the stress condition of block, improve the ability of nut block wind and wave resistance.Plain nut block hollow does not have the end, the utility model is established the base plate 3 with the block monobloc cast in nut block bottom, establish drain hole 4 on the base plate, to reduce pore water pressure, when design levee body mask, cancel the conventional placed rockfill transition zone that is located under the nut block simultaneously, and the nut block directly is placed on the rubble loaded filter after the levelling, not only save the engineering quantity of placed rockfill but also simplified working procedure.
This new type nut block structure is seen shown in Fig. 1,2.Block base plate drain hole 4 quantity and position can be adjusted according to actual needs, and block can adopt plain concrete or reinforced concrete structure.Be being connected of stiffnut block and laying unit periphery Cast-in-place concrete safe edge, the nut block base plate adjacent with Cast-in-place concrete can be laid overhanging anchor bar, is connected to integral body with peripheral cast-in-situ concrete.Adopt this new type nut block mask, make the levee body mask more economically, conveniently, safely, reliably.
During concrete the construction, with Fig. 3 form of laying is example, at first lay first row from bottom to up in the left side, protruding pin 1 upwards, back one draw-in groove 2 is pressed on the last protruding pin 1, lays secondary series more from bottom to up, two draw-in grooves 2 of secondary series nut block are pressed in respectively on the protruding pin 1 of last of these row and the first row adjacent block, lay successively, adopt cast-in-situ concrete fixed edge piece at each laying unit periphery at last, to form the whole unit chain effect.In like manner, if lay toward the left side with the right side, then protruding pin of nut block left and right sides and draw-in groove position are exchanged.
Claims (3)
1, a kind of nut block ground surface protection structure, comprise the ground surface protection structure that connects and composes one by one by the nut block, it is characterized in that: the bottom of described nut block is provided with draw-in groove and protruding pin, the draw-in groove of adjacent nut block and protruding pin match, and the bottom of ground surface protection structure is provided with the base plate integrated poured with the nut block.
