Abstract

The utility model relates to a fiber concrete revetment thin shell, belonging to water building engineering material. The structure employs a shell body of the revetment thin shell is of U shape, which is provide with a convex portion on one end and a concave portion on the other end, a convex edge is arranged on one side edge of the U-shape shell body which is connected with the other side edge of adjacent shell body. The utility model has the advantages of simple structure, convenient operation, low building price, good durability and practicality, which has good bearing and resisting ability with the action of frozen-heave force and ice- push force.

Description

Fibrous concrete bank protection shell

Technical field

The utility model relates to the water conservancy construction material type, particularly a kind of fibrous concrete bank protection shell.

Background technology

As everyone knows, China is vast in territory, and the reservoir that is in the plains region is a lot, needs repeatedly the earth dam of reinforcement ten hundreds of, river levee, the tens thousand of kilometers of sea wall shore protection.In Wall in Plain Reservoir earth dam slope protection and riverbank slope protection works, traditional bank protection form has several types such as vegetation slope pavement, pitched work, concrete flat slab bank protection and mold-bagged concrete bank protection, but all has some intrinsic defectives, can not satisfy the specific needs of engineering; At present, the form of structure that earth dam slope protection adopted mainly is in several forms such as anti-filtering material (being geosynthetics) upper berth gabion, stone masonry, dry stone wall or the prefabricated blocks of ordinary concrete; These bank protection forms have certain effect in earth dam slope protection, but still have some deficits in some aspects, for example, in the Wall in Plain Reservoir earth dam slope protection of north operation, ubiquity opposing freeze injury scarce capacity, dash the effect of washing in a pan in addition and make revetment block subside, burst apart, influence the safe operation of reservoir to a great extent.In sum, bank protection form commonly used at present is in the actual operation process, especially at north cold area, main exist following three aspects to need in addition improved problem: the one, dash the problem of washing in a pan, generally be positioned at the reservoir of flat-bottomed land, the short dike in dam is long, the shallow territory of water is wealthy, the stormy waves fetch is long, earth dam dashes at regular stormy waves and washes in a pan down, causes dykes and dams avalanche, damage, will influence the normal operation of reservoir when serious; The 2nd, problem of frost heave, be in the Wall in Plain Reservoir of north cold area, no matter earth dam slope protection adopts the bank protection form of which kind of type, inevitably all to be subjected to frost heave action, traditional bank protection form is because the problem of material and form of structure, through several freeze thawing cycle periods, the earth dam slope protection ubiquity the phenomenon of cracking avalanche, makes damage even more serious; The 3rd, ice pushes away effect, and it is the guide who causes extensive damage under the wind wave action that ice pressure causes local failure with the bank protection passing, is badly in need of solving.

The utility model content

The purpose of this utility model is to provide a kind of fibrous concrete bank protection shell, and, frost heave naughty with dashing of solving that existing earth dam slope protection exists and ice such as push away at problem; Fibrous concrete is to mix a kind of advanced composite material (ACM) that a certain amount of fiber forms in ordinary concrete, it has overcome shortcomings such as concrete tensile strength is low, limit elongation is little, fragility is big, has that good tension, bending resistance, shearing resistance, resistance are split, a performance such as endurance and high tenacity.

The technical solution of the utility model is: structurally adopt shaped form thin plate arch shell to add the straightway of certain-length, the housing that is fibrous concrete bank protection shell is the U type, end at U shell body is provided with protuberance, and the other end is provided with recess, and the recess of this protuberance and adjacent housings plugs together affixed; Side in this U shell body is provided with chimb in addition, and the opposite side edge lap of this chimb and adjacent housings prevents that Ba Tubeichong from washing in a pan; Can directly U shell body be installed during use and be laid on the earth dam upstream face of fixing the slope and completing geosynthetics, one side lap of U shell body on the chimb of adjacent U shell body, is plugged together the affixed protective slope structure that forms integral body with the recess of the protuberance of U shell body one end and adjacent housings one end simultaneously again.

Advantage of the present utility model is: simple in structure, and easy construction, lower, the good endurance of cost has good supporting capacity and opposing to dash the ability of washing in a pan under frost-heave force, ice push effect, and is practical.

Fig. 1 is a three-dimensional appearance schematic diagram of the present utility model;

Fig. 2 is a combination overlap joint schematic diagram of the present utility model;

Fig. 3 and Fig. 4 are embodiment schematic diagram of the present utility model.

The specific embodiment:

Shown in accompanying drawing 1 and accompanying drawing 2, the utility model structurally is to adopt shaped form thin plate arch shell to add the straightway of certain-length, the housing 1 that is fibrous concrete bank protection shell is the U type, end at U shell body 1 is provided with protuberance 11, the other end is provided with recess 12, and this protuberance 11 plugs together affixed with the recess 12 of adjacent housings; Side in this U shell body 1 is provided with chimb 13, and this chimb 13 overlaps with another side 14 of adjacent housings, prevents that Ba Tubeichong from washing in a pan.

Shown in accompanying drawing 3 and accompanying drawing 4, can directly U shell body 1 be installed when the utility model uses and be laid on the earth dam upstream face of fixing the slope and completing geosynthetics, one side 14 of U shell body 1 is overlapped on the chimb 13 of adjacent U shell body, again the protuberance 11 of U shell body 1 one ends and the recess 12 of adjacent housings one end is plugged together the affixed whole protective slope structure that forms simultaneously.

Claims

1, a kind of fibrous concrete bank protection shell, it is characterized in that: the housing of bank protection shell is the U type, is provided with protuberance at an end of U shell body, and the other end is provided with recess; Side at this U shell body is provided with chimb, the opposite side edge lap of this chimb and adjacent housings.
