Abstract

The utility model relates to a T-shaped, winged prefabricated component for a retaining wall, being used for assembling the T-shaped, winged concrete or the prefabricated component of steel concrete of a retaining wall (waterproof wall). The utility model comprises a wall body [3] and a tail wing plate [4]. The wall body [3] comprises a panel [1] and a web plate [2]. The extending-backward point of the lower part of the web plate is used for supporting the tail wing plate [4]. The prefabricated component can increase the antidumping capability of the retaining wall (the waterproof wall), and cause the soil pressure of the tail wing plate to be conveyed into a foundation through a direct line. The component is respectively prefabricated in order to conveniently transport. The retaining wall (the waterproof wall) which is made of the prefabricated component has the advantages of material saving and good performance. The utility model is suitable for various foundations of the water conservancy, railways, highways, etc.

Description

T-shaped, winged prefabricated componect for retaining wall

The utility model relates to a kind of prefabricated units of constructing retaining wall (or mine dam) in the Foundation Design, especially for farmland water conservancy works.

The existing prefabricated units of constructing retaining wall (or mine dam), normally monolithic concrete or reinforced concrete prefabricated, form by panel, triangular web and base plate.For example in Japan clear 58---the prefabricated retaining wall member described in No. 19818 patents forms by panel, base plate and triangular web are integral prefabricated exactly.It utilizes the vertical earth pressure that bears on the base plate to make member have resistance to capsizing, keeps stablizing (see figure 1), and is embedded with nut in each base plate rear end portion, and during assembly unit, prefabricated section connects to integral body with bolt up and down, to increase resistance to capsizing.But anterior angle---the turning cylinder that topples is nearer at the bottom of wall owing to the position that resists the vertical earth pressure that inclines, so for keeping wall stability, just require bigger base areas, member is complex-shaped simultaneously, so prefabricated comparatively difficult.

The purpose of this utility model is improved at above-mentioned member exactly, increases the anti-ability of inclining of body of wall, simplifies the member shape simultaneously, provide a kind of can be prefabricated respectively, retaining wall (or mine dam) prefabricated units of convenient transportation.

Technical solution of the present utility model is, with concrete (or steel concrete) difference precast wall body (3) and (4) two basic building blocks of tail plate.Body of wall is made up of the web (2) that rectangular panel (1) and bottom extend back, and section is T-shaped.Web (2) afterbody support rectangle tail plate (4) (see figure 3).Wall panel (1) bears seepage water pressure behind horizontal earth pressure P and the wall, is the principal element that body of wall topples.Tail plate (4) on web (2) tail end replaces base plate and bears vertical earth pressure L, make the vertical earth pressure position away from wall at the bottom of anterior angle, increased the anti-ability of inclining like this, play the effect of stabilization wall (3).The length that web (2) stretches out backward and the size of fin area are to guarantee that wall body structure is stablized to be as the criterion.In addition, tail plate (4) directly places on the tail end of web, the soil pressure on the empennage is transmitted to the basis with the most direct circuit, thereby simplified the structure.If any waterproof requirement, neighboring walls panel junction can be established and be contained a mouthful seam.For preventing that tail plate (4) from gliding, web (2) rear portion can make coign (5).

The utility model is described in further detail with example below: as make high 140 centimetres of prefabricated retaining wall members (seeing Fig. 4, Fig. 5, Fig. 6), the high h of body of wall is 140 centimetres, the wide a of panel is 50 centimetres, the wide b of tail plate is 50 centimetres, web top length c is 20 centimetres, about 1/3rd highly locate to extend back in the distance bottom, and the size of web bottom lengths d and tail plate length e is decided with the mechanical property of the earth that bankets behind the wall.Panel, web and tail plate thickness are decided on the soil property of banketing, prefabricated quality and Ferry Status, are generally 5～10 centimetres.All members of body of wall are pure concrete prefabricated, for the convenient construction lifting, have preset lifting eye (6) on body of wall.

The retaining wall that wall is high 150～250 centimetres can divide and make two-layer prefabricated retaining wall member, and stack forms the retaining wall combined member up and down, and as high 220 centimetres of retaining walls, wall body construction high h in upper strata is 140 centimetres, and the high h of lower floor's wall body construction is 80 centimetres.Because of supporting and stressed needs, web top length c1 of lower floor and bottom lengths d1 will suitably strengthen (see figure 7).

Higher retaining wall can use the prefabricated retaining wall member of multilayer, and the levels wall body construction preferably adopted and contained a mouthful connected mode this moment, to guarantee the stability of retaining wall.

The utility model has the advantages that: that comparatively evenly reasonable, the anti-turning over of inside and outside stressed distribution covers power is strong, simple in structure, it is prefabricated to be convenient to.The retaining wall of making of it (or mine dam) can be applicable to all kinds of Foundation Designs such as water conservancy, railway, highway.

By accompanying drawing as can be known, one of the utility model embodiment is made up of body of wall (3) and tail plate (4).Body of wall (3) is made of panel (1) and web (2).Be convenient lifting, prefabricated a plurality of lifting eyes (6) on body of wall; For preventing tail plate (4) landing, be shaped on the coign (5) that cooperatively interacts and be connected in advance at binding site with body of wall (3).

Embodiment two of the present utility model is two layers of combined member.Its bottom member is seen Fig. 7.

According to different situations, can use concrete or steel concrete prefabricated respectively to member of the present utility model.For multilayer (more than three layers or three layers) retaining wall member, its joint portion all needs mouthful be connected prefabricated containing, with the stability of the retaining wall that guarantees to make of its.
