The utility model discloses a set up the iron sheet on arch dam abutment side slope surface, can stabilize and block the tiny rock block of side slope and do not take place to fall the piece, can be about to the bold stone rail that the side slope drops, ensured side slope and dam engineering construction period safety. The anchor rods are anchored into the side slope of the dam abutment of the arch dam, so that large dispersed separated stones in the loosening blasting influence range of the side slope of the dam abutment can be connected in series well, and the safe operation of side slope engineering is ensured.
Description
Technical field
The utility model relates to a kind of novel slope retaining structure, and the especially supporting and protection structure of Arch Dam Abutment side slope belongs to water conservancy project water retaining structure slope retaining structure technical field.
Background technology
At present in domestic water electrical engineering process of construction, especially in the time that Arch Dam Abutment slope excavation is constructed, excavation and supporting sequential have been generally to carry out immediately supporting after the construction of upper level slope excavation, after supporting construction completes, can carry out the excavation construction of next stage side slope.As Arch Dam Abutment side slope, its side slope ROCK CONDITIONS should be better, and rock matter classification is generally 3 classes or more than 3 classes, and rock quality is hard, can bear the thrust of very large dash head.For guaranteeing stability of slope and dam construction phase safety, generally dam abutment side slope is taked to lay the supporting and protection structure measure such as anchor pole and spray steel fibre reinforced concrete, at present as shotcrete linked network structure is taked to established dam abutment side slope conventionally in great Hua water, kind mud slope and trunk ridge etc., to guarantee not occur, side slope surface falls piece to domestic water electrical engineering and localized mass stone break-off occurs, while ensureing that Arch Dam Abutment side slope is down excavated and dam construction phase safety.Because Arch Dam Abutment side slope has the advantages that area is little and narrow, in the time taking to lay anchor pole and the supporting of spray linked network concrete structure, its working procedure complexity, construction period human and material resources resource drops into more, causes slope retaining and excavation construction progress slow simultaneously; Because slope retaining structure is temporary structure, must, by the concrete chisel that is sprayed on side slope surface divided by guaranteeing dam concrete and the intact combination of side slope basement rock, increase engineering construction operation when the later stage when dam construction.Therefore, existing Arch Dam Abutment slope retaining structure or not ideal enough.
Utility model content
The purpose of this utility model is the supporting problem for solving the Arch Dam Abutment side slope existing in prior art, and a kind of supporting and protection structure of novel Arch Dam Abutment side slope is provided.
The technical solution of the utility model is such: it is a kind of structure for Arch Dam Abutment slope retaining, its structure need to comprise the acting in conjunction together of Arch Dam Abutment side slope, it is to be equipped with one deck iron sheet on the surface of Arch Dam Abutment side slope, and penetrate iron sheet with many anchor poles and anchor in Arch Dam Abutment side slope, the termination that anchor pole is exposed at outward outside iron sheet uses nut fastening, between this nut and iron sheet, is provided with steel plate washer.Between steel plate washer and iron sheet, be also provided with spring, this spring housing on anchor pole for iron sheet being pressed on to the surface of described Arch Dam Abutment side slope.
As preferred version, iron sheet is generally zinc-plated structure, possesses compared with strong corrosion resistant, and thickness is 0.8 ~ 2.0mm.The degree of depth that anchor pole anchors into Arch Dam Abutment side slope inside is 3.0 ~ 9.0m, and on Arch Dam Abutment side slope surface, the spacing between adjacent anchor pole is 2.0 ~ 5.0m.
The beneficial effects of the utility model are: adopt, on Arch Dam Abutment side slope surface, iron sheet is set, iron sheet possesses certain pliability, fit in preferably side slope surface, the tiny block of stone of side slope of can firmly and blocking not to fall piece phenomenon, for boulder large and that be about to come off, in the time there is crimp or off-load displacement, iron sheet possesses certain rigidity, under the cushioning effect of the fixing and spring of nut, can, by the boulder fence that is about to come off, bring potential safety hazard to guarantee that boulder does not fall down to lower floor's slope construction and dam construction; Iron sheet possesses compared with strong corrosion resistant while being zinc-plated structure, can guarantee can, because being lost normal function by rainwater corrosion, not guarantee engineering safety operation compared with long construction period.Be 3.0 ~ 9.0m because anchor pole generally anchors into dam abutment length of slope, spacing is 2.0 ~ 5.0m, ensures that major part in dam abutment side slope loosening blasting influence basin is fallen apart can better be cascaded from piece stone, guarantees to form side slope safety operation.Because Arch Dam Abutment side slope has the advantages that area is little and narrow, take iron sheet and combining anchor supporting greatly to simplify side slope supporting construction operation, save human and material resources resource, accelerate side slope supporting construction progress, simultaneously as temporary structure, in the time that dam concrete is built, directly iron sheet is turned on and removed to the nut of corresponding site, Demolishing Technology difficulty is low, and iron sheet can reuse after removing.
brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Description of reference numerals: 1-Arch Dam Abutment side slope, 2-iron sheet, 3-anchor pole, 4-spring, 5-steel plate washer, 6-nut.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See Fig. 1, Fig. 1 has shown overall structure of the present utility model, and as we can see from the figure, the utility model is by the surface coverage one deck iron sheet 2 in Arch Dam Abutment side slope 1, then penetrate iron sheet 2 with anchor pole 3 and anchor in Arch Dam Abutment side slope 1, form so a basic supporting and protection structure.Anchor pole 3 exposes termination a nut 6 is set, and nut 6 arranges a steel plate washer 5, and a spring 4 is set between steel plate washer 5 and iron sheet, and steel plate washer 5 and spring 4 are all enclosed within on anchor pole 3.
Iron sheet 2 thickness are generally zinc-plated structure, and thickness is 0.8 ~ 2.0mm, and anchor pole 3 anchors into Arch Dam Abutment side slope 1 length and is generally 3.0 ~ 9.0m, and anchor pole 3 spacing are generally 2.0 ~ 5.0m.
The supporting and protection structure of this Arch Dam Abutment side slope 1 of the present utility model is interim hydraulic structure structure.
When the utility model is implemented, by Arch Dam Abutment side slope 1 side slope surface, iron sheet 2 being set, the tiny block of stone of side slope of can firmly and blocking not to fall piece, and the boulder fence that side slope can be about to come off, has guaranteed side slope and dam engineering construction period safety.Adopt anchor pole 3 to anchor into Arch Dam Abutment side slope 1, ensure that major part in dam abutment side slope loosening blasting influence basin is fallen apart can better be cascaded from piece stone, guarantee slope project safe operation.Compared to existing technology, the utility model is simple in structure, quick construction, supporting effect are easy to ensure, when dam concrete is built simultaneously, remove the iron sheet of corresponding site, difficulty of construction is little, technical security is reliable.
Be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
