Abstract
The utility model relates to a linkage structure of a gravity dam and an unfavorable geological bank slope, and aims to solve the technical problem through providing the linkage structure of a gravitydam and an unfavorable geological bank slope. An active support manner is used for improving the stressed state of an unfavorable geological bank slope and ensuring the stability of bank slope. The technical scheme for solving the problem is as follows: the linkage structure of a gravity dam and an unfavorable geological bank slope is characterized in that a set of skidproof stakes are uniformlyarranged at the connection part of the gravity dam and the unfavorable bank slope, an inter-state plate is arranged on a slope surface between every two contiguous skidproof states, the upper part ofthe stake body of each skidproof stake is provided with a prestress anchor rope, and a water stop slot is formed between the dam body and the skidproof stakes connected with the dam body. The utilitymodel is mainly used in hydraulic and hydro-power engineering.
Description
Technical field
The utility model relates to the draw bail of a kind of gravity dam and unfavorable geology bank slope.Be mainly used in the Hydraulic and Hydro-Power Engineering.
Background technology
Gravity dam is one of important dam type that extensively adopts in the Hydraulic and Hydro-Power Engineering, because the western complicated topographic and geologic condition and the operating characteristic of gravity dam itself, gravity dam high slope and superelevation side slope often occur with connecting of two sides bank slope, when the bank slope geological conditions is unfavorable, often cause the stability of slope problem.
At present, the engineering that has is by engineering measures such as employing anchor arm-ties, solved the articulation issues of indivedual gravity dams and the bad bank slope of geology, but because the restriction of this structure construction program and design feature, there are shortcomings such as slope retaining is untimely, the construction safety problem is outstanding in this passive retaining structure.
Summary of the invention
The technical problems to be solved in the utility model is: provide the draw bail of a kind of gravity dam and unfavorable geology bank slope at the problem of above-mentioned existence, with the form of active support, improve the stress of unfavorable geology bank slope, guarantee the stability of side slope.
The technical scheme that the utility model adopted is: the draw bail of a kind of gravity dam and unfavorable geology bank slope, it is characterized in that: one group of antislide pile evenly is set in the junction of gravity dam and unfavorable geology bank slope, on domatic between adjacent each antislide pile plate between stake is set, described antislide pile pile body top is provided with prestress anchorage cable, between dam body and the antislide pile that is attached thereto water stopping trough is set.
Described antislide pile is divided into a preface antislide pile and two preface antislide piles, and a preface antislide pile and the dislocation of two preface antislide piles are arranged.
The plate top is provided with the contact beam between described stake.
The beneficial effects of the utility model are: the utility model is by calculating the excavation slope residual pushing force, plate and anchor cable between reasonable Arrangement antislide pile, stake, form anchor cable reinforced concrete pile board wall, realize the positive connection of dam and bank slope, effectively reduce unfavorable geological condition bank slope engineering slope height simultaneously, improved the stress of unfavorable geology bank slope, improved working security, guarantee the engineering slope safe operation, saved construction investment.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment evenly is provided with one group of antislide pile in the junction of gravity dam and unfavorable geology bank slope, remain basically stable with dam crest road surface 6 in the stake top, and the pile body diameter that is connected with dam outline line 9 is big than other pile body diameters, for guaranteeing bank stability, each pile body all need pass completely through severely-weathered fracture area 8 and go deep into the weak-weathered rock body and be no less than 1/4 pile body length.For guaranteeing stake well excavation safety, adopt the steel concrete supporting around the stake well, on domatic between adjacent each antislide pile plate 3 between stake is set, prevent domatic local buckling between stake, described antislide pile pile body top is provided with prestress anchorage cable 4, to reduce pile body deformation and to improve pile body and the stress condition of side slope, for preventing antislide pile and dam body binding site generation seepage, between dam body and the antislide pile that is attached thereto sealing 10 is set, plate 3 tops are provided with contact beam 5 between described stake.
The job practices of present embodiment is:
A, in order to prevent from the work progress to take place the landslide phenomenon, adopt branch preface excavation in the work progress, build antislide pile stake well, in this example, at first excavation is built a preface antislide pile 1, after treating that its concrete strength reaches requirement, excavation is built two preface antislide piles 2 between each preface antislide pile 1, and stake well excavation construction needs the supporting while excavating, excavation is promptly built pile concrete after finishing, and with antislide pile that dam body is connected on reservation sealing 10 grooves;
B, treat that the antislide pile concrete pouring construction is finished, after concrete strength of pile reaches requirement, press excavation line 7 beginning stage excavation dam foundation foundation ditches, plate 3 between the stake of excavation one deck construction one deck according to the bank slope geological conditions;
C, wait to be excavated to the anchor cable design altitude, stop excavation, construction anchor cable, anchor cable prestressing force lock value need and antislide pile later stage displacement coupling;
D, treat that anchor cable construction is finished after, continue construction according to step b, plate between stage excavation dam foundation foundation ditch, construction stake is until being excavated to design altitude;
E, cleaning foundation plane are built dam concrete, and are buried sealing 10 underground at the pile body preformed groove, in case the seepage phenomenon takes place.
