Description
Technical field
The utility model relates to arranges the working packed sand pocket of body protection cushion coat under water.
Background technology
The Longkou section levee body of corral engineering passes through packed sand construction technologies such as packed sand throwing and filling, the big sand pocket of filling, elongated packed sand with the absolute altitude lifting of levee body under water more, after the levee body absolute altitude is raised to a certain degree, lays soft raft and carries out Longkou river bottom protection protection.River bottom protection protection in Longkou is accomplished, as laying prefabricated block above that, and the situation that certainly will exist hard material and flexible material directly to contact, then soft raft is very easy to be damaged, thereby causes river bottom protection protection to be destroyed, and directly has influence on the safety of embankment levee body.For example river bottom protection protection absolute altitude in the husky reservoir engineering of green grass Longkou is-4.0m, and the Longkou protection period reaches-7.0m/s with closure phase limit velocity, and under high flow rate like this, for improving safety factor, the pattern of double-deck row's body protection: 1300g/m has been adopted in the river bottom protection protection of Longkou
2Superpower sand rib soft raft and 380g/m
2Whole concrete locking plate soft raft.For ease of later stage reservoir embankment impervious wall construction; In the 8m regional extent of main Longkou impervious wall construction; Lay the precast concrete block of being convenient to reclaim (or claiming big square); Big square physical dimension is 3.8m * 2m * 1.4m (the wide * of long * is high), and the heavily about 30t of monomer is loaded to its direct lifting on the levee body of laying river bottom protection protection row body during construction.Packed under water sand is constructed, and receives the characteristics and the limitation of its technology, and certainly existing the part has the discrepancy in elevation; Overlap apertured phenomenon; After laying soft raft, as directly laying hard material (like prefabricated blocks such as big squares) above that, the discrepancy in elevation that will certainly the gene basis is with local slit and the tear failure of the row's of causing body; Make topping lose original function, cause chain breaking reaction.For guaranteeing levee body safety, must guarantee that the soft raft topping is not destroyed, therefore before laying big square, must implement levelling and buffering protection that certain cushion coat carries out the local discrepancy in elevation.In the at present existing construction technology; Fragmentary stone, packed rubble or the small size sand pockets etc. of adopting carry out the precalculated position waterborne construction of jettisoninging as cushion coat more; Jackstone in the protection of for example conventional soft raft river bottom protection also is to carry out the jackstone construction again after laying fragmentary stone or the packed rubble of one deck 20～30cm.Under the situation slow at flow velocity, that the depth of water is shallow, this kind mode is used more, and the jackstone on it is less demanding for the planarization under water of the fragmentary stone of cushion coat, packed rubble or little sand pocket etc.; But in the depth of water, flow velocity under the high and working condition that planarization had certain requirements; Fragmentary stone, packed rubble or little sand pocket are less because of volume, are subject to the influence of flow action, when jettisoninging construction; Be difficult to reach preposition under water; Even might be stacked into together, increase the local discrepancy in elevation, do not have the effect of levelling and buffering.For satisfying the depth of water, high flow rate and, needing improve, create a kind of novel cushion coat to cushion coat to the planarization buffer protection under the working condition of having relatively high expectations.
The utility model content
The utility model provides a kind of packed sand pocket of constructing as cushion coat on the body of arranging under water, solves the buffer problem of laying prefabricated block on the soft raft.
The technical scheme of the utility model adopts packed sand pocket, it is characterized in that the size of packed sand pocket is made according to the maximum size of buffer area area or handling, and the bag material adopts 230g/m
2The woven cloth of polypropylene filament yarn; Hang draw ring along every the establishing of bag length direction at a distance from 1m; Hanging the draw ring material adopts the wide polypropylene fibre reinforced bands of 10cm and makes closure along the bag bottom; Make bag in charging process, be easy to control and dash to irritate thickness, can bear certain weight in the handling process and be unlikely to cause the tear failure of bag; Packed sand pocket utilizes slush pump to charge, and charges THICKNESS CONTROL at 15～20cm, guarantees to charge evenly smooth.
The outstanding feature of the utility model is to use packed sand pocket to carry out cushion coat construction, avoids hard material such as prefabricated block directly to touch the soft raft body, avoids row's body is damaged; Simultaneously can carry out levelling under water to a certain degree, reduce the local out-of-flatness discrepancy in elevation, improve construction quality and also made things convenient for the later stage of prefabricated block to hang to remove laying the basis.Be packed in bag sand pocket as cushion coat conventional fragmentary stone, packed rubble or little sand pocket etc. have anti-current-rush power by force, advantage such as levelling under water is effective, and buffering effect is obvious.Through the GPS navigation system; Utilize special hanger to carry out the lifting of the packed sand pocket of cushion coat, can guarantee that packed sand pocket is placed to predetermined submarine site, overcome fragmentary stone, the inaccurate difficult problem of packed rubble or little sand pocket precalculated position under water; Through controlling the thickness that charges of packed sand pocket; It is satisfactory for result to hang the back levelling under water, can slow down the local out-of-flatness discrepancy in elevation, the purpose that has played levelling conscientiously and cushioned under water.
