Abstract

The utility model discloses a dam combined with a plurality of precast concrete plates, wherein, a plurality of precast concrete plates with internal stiffeners are arranged on the preset position of the ground layer in turn and are connected with each other to form a continuous wall dam; the gaps between the plates of the dam are filled with water stop f seal and resist water, then is injected with grout to cure for strong joint. The problems of complex original construction method, long construction cycle, high construction cost and expense are solved. Another technical proposal of the combination dam is that the dam comprises a longitudinal dam and a transverse dam, wherein, the precast concrete plates with internal stiffeners are connected with each other to form the longitudinal dam, and one or multiple precast concrete plates which are connected with each other and vertical to the longitudinal dam, are arranged on the upstream side of the longitudinal dam to form the transverse dam. The utility model has the advantages of high self-strength due to the reinforced concrete structure, good sturdiness due to cure for strong joint to be a whole, convenient construction operation, short cycle, high efficiency, vertically constructing on the upstream side of the embankment or in the water area of a channel, a pond, a river, a lake and a sea, less foundation earthwork, less paved area and low construction cost.

Description

Precast concrete plank combination dykes and dams

One, technical field

The utility model relates to waters embankment protection dykes and dams, specifically is a kind of precast concrete plank combination dykes and dams.

Two, background technology

Waters embankments such as canal, the pool, river, river, lake, sea because of long period of soaking, wash away normal subsiding, pile up to stop up water stream channel or raise the bed that becomes silted up, not only current are not smooth, and polluted water, clear up very difficult yet.In order to prevent that the be everlasting side that meets water of embankment of this class problem from taking the method for hardening and reinforcing, promptly build bank protection or retaining wall in the side that meets water of embankment.At present, solid pin of bank protection and retaining wall generally all adopt stone or concrete to build body by laying bricks or stones.During construction, encircle and hunt down the weir earlier, adopt water pump to draw water then or well-points dewatering, and after needing cleaning foundation ditch mud and quicksand, can carry out stone or concrete is built body construction by laying bricks or stones.This body foundation of building by laying bricks or stones is shallow, and intensity is low, and earthwork excavated volume is big, the job practices complexity, and the construction period is long, engineering cost expense height.

Three, summary of the invention

Goal of the invention of the present utility model is to design a kind of precast concrete plank combination dykes and dams at the problems referred to above, promptly be mounted to the precalculated position, stratum successively with precast concrete plank, and the formation precast concrete plank combination dykes and dams that interconnect, solve the former job practices complexity of using, construction period is long, the problem that the engineering cost expense is high.

Goal of the invention of the present utility model is achieved through the following technical solutions: be mounted to the precalculated position, stratum successively and interconnected by the interior precast concrete plank that reinforcing rib arranged and form the diaphragm wall dykes and dams, the cement paste that reinjects behind the slit filling waterstop sealing water proof between the dykes and dams plate stitches connection admittedly.

Another technical scheme of the present utility model is to constitute suitable, horizontal combination dykes and dams by the interior precast concrete plank that reinforcing rib the arranged longitudinal dike that forms and the monolithic of installing perpendicular to longitudinal dike in the side that meets water of longitudinal dike or the polylith horizontal dam that precast concrete plank forms that interconnects that interconnects, and filling waterstop in slit seals the cement paste that reinjects behind the water proof and stitches connection admittedly between the dykes and dams plate.

The good effect that the utlity model has: the utility model is a reinforced concrete structure, self intensity height; Gu seam is coupled to integral body, soundness is good; Constructing operation is convenient, the cycle is short, efficient is high; Can vertically construction in the upstream face of embankments such as canal, the pool, river, river, lake, sea or waters, the basic earthwork amount is little, and the area of mating formation is few, and engineering cost is low.

Five, the specific embodiment

Fig. 1 is an overall structure schematic diagram of the present utility model, is the overall structure of precast concrete plank diaphragm wall dykes and dams shown in the figure, and Fig. 2 is the left surface view of Fig. 1, and Fig. 3 is the right flank view of Fig. 1, Fig. 4 be among Fig. 1 A-A to sectional view.In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is mounted to the precalculated position, stratum successively and is interconnected by the interior precast concrete plank that reinforcing rib arranged and forms the diaphragm wall dykes and dams, and the cement paste that reinjects behind the slit filling waterstop sealing water proof between the dykes and dams plate stitches connection admittedly.The diaphragm wall dykes and dams are to be made of the precast concrete plank 1 that polylith interconnects.One side of precast concrete plank 1 has tenon slide plate 2, and opposite side has spill chute 3, and all there is semicircle water proof road 4 two sides of precast concrete plank 1, and semicircle water proof road 4 forms by mould when prefabricated.When assigning, precast concrete plank one side tenon slide plate 2 inserts the spill chute 3 of opposite side, makes socket joint connection between adjacent two blocks of precast concrete plank 1 plates.One side tenon of precast concrete plank 1 also can be I shape, and half exposes half of I shape in plate in advance; The spill chute 3 of opposite side also can be square pipe with seam; Socket joint connects between two blocks of adjacent precast concrete plank 1 plates.The semicircle water proof road 4 that connects between adjacent precast concrete plank 1 plate in back is combined to form cylindrical water proof road, and filling waterstop 5 sealings in the cylindrical water proof road are injected liquid cement and stitched connection admittedly in all the other slits or the cavity between plate.But the also film bag sealing of the interior cement injection of filling in the cylindrical water proof road.

Fig. 5 is another embodiment of the present utility model, is the overall structure schematic diagram of suitable, the horizontal combination dykes and dams be made up of precast concrete plank, and Fig. 6 is the left surface view of Fig. 5, and Fig. 7 is the right flank view of Fig. 5, Fig. 8 be among Fig. 5 A-A to sectional view.In conjunction with Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, this scheme is to be made of the interior precast concrete plank 1 that reinforcing rib the arranged longitudinal dike that forms and the monolithic of installing perpendicular to longitudinal dike in the side that meets water of longitudinal dike or the polylith horizontal dam that precast concrete plank 1 forms that interconnects that interconnects, and slit filling waterstop 5 seals the cement paste that reinjects behind the water proofs and stitches connection admittedly between the dykes and dams plate.Longitudinal dike is that a plurality of precast concrete planks that interconnect 1 constitute, horizontal dam in the side that meets water of longitudinal dike perpendicular to the parallel installation of longitudinal dike single row or multiple rows.Horizontal dam can be installed perpendicular to longitudinal dike by monolithic or the polylith precast concrete plank 1 single side that meets water at longitudinal dike that interconnects, and also can be installed perpendicular to longitudinal dike by monolithic or the polylith side that meets water that precast concrete plank more than 1 comes longitudinal dike that interconnects.Sealing, the bind mode of suitable, the horizontal combination dykes and dams of precast concrete plank are the same.
