A kind of combined concrete sash bank protection and its construction method
Technical field
The present invention relates to a kind of precast concrete product to be used for bank protection, belongs to engineering material.
Background technology
At present, in existing protecting slope of dam project, more using cast-in-place concrete, the coagulation penus plastic concrete, have
Mobility, and dykes and dams have the gradient, so difficulty of construction is very big, process is very cumbersome, and construction cost is high, and operating efficiency is low, work
The shortcomings of Cheng Zhiliang is difficult to ensure that, and can only be constructed in summer, and winter can not construct.
The content of the invention
Good it is an object of the invention to provide a kind of integral coherence, production and construction cost are relatively low, and operating efficiency is high, and
And the pre-cast concrete products easily examined of construction quality and its construction method.
The technical scheme that the present invention takes is as follows:
A kind of combined concrete sash bank protection and its construction method, it is characterized in that:Assembling-type precast concrete sash is protected
Slope structure includes main piece of precast concrete sash bank protection and precast concrete sash bank protection cushion block.Precast concrete sash bank protection master
Block, as shown in figure 1, middle part is rectangular parallelepiped structure, the end face of cuboid is respectively by two orthogonal main piece of end faces (2), (3)
Formed, and main piece of end face (2), (3) and the plane perpendicular of cuboid.Precast concrete sash bank protection cushion block, as shown in Fig. 2
Precast concrete sash bank protection cushion block is made up of the cushion block matrix (4) and 4 square cushion block boss (5) of square.4 just
Square cushion block boss is located at the corner of cushion block body upper surface, the groove width formed between the square cushion block boss of homonymy two
Match with the width of concrete prefabricated main piece of sash bank protection.During construction, precast concrete bank protection cushion block is square to be distributed in
On dykes and dams, the interval of precast concrete bank protection cushion block and the equal length of main piece of precast concrete slope protection block.Every two pieces prefabricated
Main piece of precast concrete bank protection is placed between concrete revetment cushion block, forms precast concrete sash bank protection, as shown in Figure 3.
Beneficial effects of the present invention are as follows:
Compared with traditional cast-in-place concrete bank protection, main piece of assembling-type precast coagulation sash bank protection and cushion block derive from enterprise
Mass mechanized production is processed, and the property indices of product easily detect, and the quality of precast concrete sash can ensure, because
This, there is precast concrete sash bank protection quality easily to ensure, can large-area construction, the advantage of short time limit, while be adapted to ground
Base deformability is preferable, and the features such as deformation as caused by frost heave, differential settlement, construction is simple, easy to maintain, investment is smaller etc.
Plurality of advantages.
Brief description of the drawings
Fig. 1 is main piece of the assembling-type precast concrete sash bank protection of patent of the present invention.
Fig. 2 is the assembling-type precast concrete sash slope protection bedding course block of patent of the present invention.
Fig. 3 is the assembling-type precast concrete sash bank protection planar effect picture of patent of the present invention.
Wherein:(1) block bar face based on, block end face based on (2) and (3), (4) are cushion block matrix, and (5) are cushion block boss.
Embodiment:
Assembling-type precast concrete sash protective slope structure, including main piece of precast concrete sash bank protection and precast concrete frame
Lattice bank protection cushion block.
Main piece of precast concrete sash bank protection, as shown in figure 1, main piece of middle part of precast concrete sash bank protection is cuboid knot
Structure, the end face of cuboid are formed by two orthogonal main piece of end faces (2), (3) respectively, and main piece of end face (2), (3) with
The plane perpendicular of cuboid.
Precast concrete sash bank protection cushion block, as shown in Fig. 2 cushion block of the precast concrete sash bank protection cushion block by square
Matrix (4) and 4 square cushion block boss (5) compositions.4 square cushion block boss are located at the four of cushion block body upper surface
Angle, the width phase of main piece of groove width and the precast concrete sash bank protection of the formation between the square cushion block boss of homonymy two
Match somebody with somebody.
The construction method of assembling-type precast concrete sash bank protection, according to the design requirement of protecting slope of dam, designs and meets
Main piece of the assembling-type precast concrete sash bank protection of quality requirement and the specific size of concrete sash slope protection bedding course block, it is pre- during construction
Concrete sash slope protection bedding course block processed is square to be distributed on dykes and dams, and the interval of precast concrete sash bank protection cushion block is mixed with prefabricated
Coagulate the equal length of native main piece of sash bank protection.Precast concrete sash is placed between every two blocks of precast concretes sash bank protection cushion block
Main piece of bank protection, precast concrete sash bank protection is formed, as shown in Figure 3.
