Abstract
A precast concrete for closure casting is a triangular pyramid, a lug is embedded in one corner angle of one end of the precast concrete, four faces of the precast concrete are all inwards concave or outwards convex, each inwards concave face of the precast concrete becomes a pyramid-shaped groove, the corner angle of one end of the precast concrete is precast into a plane, and the lug is embedded in the plane, and the precast concrete is made of concrete or reinforced concrete. According to the precast concrete for closure casting, each of four faces of a conventional triangular pyramid is manufactured into the inwards concave groove or the outwards convex bulges, thus increasing the fiction of the structural body and the bite force among the structural bodies; all faces of the together piled precast concretes cannot completely lean together, and certain gaps are formed among casting bodies, so the precast concrete can shunt water flows during closure to reduce the closure difficulty, and the aim of improving the water flow-scouring resisting capacity of the cast precast concrete is achieved.
Description
Technical field
The utility model relates to a kind of concrete precast element, is specifically related to a kind of being applicable to and dams or the concrete precast element of jettisoninging under water of emergency repair.
Background technology
At present, Hydraulic and Hydro-Power Engineering dam and flood-fighting in, often adopt precast concrete four sides block to jettisoning under water.Because conventional concrete tetrahedron surface is the plane, and en-block construction and weight are bigger, when jettisoninging between the block interlock ability relatively poor, the anti-upset of concrete tetrahedron is indifferent when current scour power is big, do not obtain maximum performance, cause and throw the work of filling out and difficulty increasing.
Summary of the invention
It is lighter that technical problem to be solved in the utility model just provides a kind of monolithic weight, is easy to jettisoning, and mutually snap-in force is strong between the block, and impact resistance is strong dams to jettisoning and use concrete precast element.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of dam to jettisoning use concrete precast element, prefabricated component is the triangular cone, is embedded with hanger at end corner angle of prefabricated component, four faces of prefabricated component all concave and become or to outer lug.Pyramid groove of each face formation that described prefabricated component concaves and becomes.Prefabricated component one end corner angle are prefabricated into horizontal plane, bury hanger underground at horizontal plane.Prefabricated component adopts concrete or steel concrete to make.
The new shape of this practicality provides a kind of dam to jettisoning use concrete precast element, by each plane of conventional quadrilateral pyramid being made the groove that caves inward or outside projection, increased the frictional force of structure, increased the snap-in force between the structure, changed the plane combination that different prefabricated components is in contact with one another, make and pile up together this and install between each face and can not be close together fully, jettisoning and certain space to occur between the body, when damming, current can be shunted to reduce closure difficulty, reach the purpose of the anti-current scour ability that improves the back prefabricated component of jettisoninging.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is elevation of the present utility model.
Fig. 2 is vertical view of the present utility model.
Fig. 3 is that the A-A of Fig. 2 is to view.
The specific embodiment
Shown in Fig. 1-3, a kind of dam to jettisoning use concrete precast element, prefabricated component 1 is the triangular cone, is embedded with hanger 3 at end corner angle of prefabricated component 1, the change that all concaves of 1 four faces of prefabricated component.Pyramid groove 2 of each face formation that prefabricated component 1 concaves and becomes.For ease of hanger 3 is installed, prefabricated component 1 one end corner angle are prefabricated into horizontal plane, bury hanger 3 underground at horizontal plane, it is more firm that hanger 3 is installed.
The utility model also can all arrange outside projection with 1 four faces of prefabricated component, also can reach same purpose.
The utility model provides dams to jettisoning and uses concrete precast element, and prefabricated component 1 adopts concrete or steel concrete to make.
Before prefabricated, the first upright and reinforcement by connection with the template frame that processes, and installed and fixed hanger 3 adopts plain concrete or buries steel mesh reinforcement after-pouring concrete underground, and building finishes reached after the age of concrete is collapsible die, and the utility model is finished.
During use, can adopt dump truck with a plurality of, (3-5), the utility model that uses wire rope to link together is transported to the scene and jettisonings, and wire rope is a plurality of, (3-5), the utility model is cascaded, and more can increase whole impact resistance; Also can adopt crane to cooperate single jettisoninging as required.
