Description
Technical field
The present invention relates to the asphaltic concrete core wall in hydraulic and hydroelectric engineering, especially a kind of asphaltic concrete core wall pedestal
Construction method and its structure.
Background technique
In hydraulic and hydroelectric engineering, asphalt concrete core dam is a kind of common water retaining structure.Concrete pedestal can
Using the lid weight as grouting, the structure of antiseepage can also be used as, be a part indispensable in asphaltic concrete core wall.
Concrete pedestal is applied as mass concrete when constructing to prevent the generation of thermal cracking that can be divided into several pieces
Work does parting processing, then clogs sealing between these point of good concret block, prevent the leakage of water between seam, such
Way makes to form permanent seam between concret block, thus the position that parting sealing is arranged is often weak link, is easy by water
Body destroys, and carries out filling sealing in permanent seam, and working procedure is complicated, and water-stagnating effect is unstable, is more easily damaged.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the shortage of prior art, provide one kind and be easy to construct, and formed
Whole continuous whole asphaltic concrete core wall basement construction method and its structure.
In order to solve the above technical problems, the present invention provides a kind of asphaltic concrete core wall basement construction methods comprising
The following steps:
1) pedestal concrete block is planned to multiple first concrete blocks and multiple second concrete blocks along the length direction of pedestal,
It is embedded one second concrete block between adjacent first concrete block, and the section configuration of the first concrete block is trapezoid, second
The section configuration of concrete block is inverted trapezoidal；
2) pouring construction of all first concrete blocks is carried out along base length direction, and is stayed between adjacent first concrete block
The second concrete block pours sky out；
3) it after all first concrete block constructions, is spaced at least 28 days, the first concrete at interim seam of constructing will be located at
Block contact surface dabbing removes loose matter, and after rinsing well, smears cement mortar, then be embedded BW water expandable waterstop, most laggard
The pouring construction of the second concrete block of row makes the first and second concrete block form an entirety.
Further, the length of first concrete block is determined according to construction speed and construction intensity, generally 20 ~
25m, the length of second concrete block are 1 ~ 1.5m.
Further, the lower base angle of first concrete block is 60 ° ~ 75 °.
Further, the position temporarily stitched of constructing should be set on the base by smaller and convenient for construction the position of shearing.
In order to solve the above technical problems, the present invention also provides a kind of asphaltic concrete core wall base constructions comprising more
It is a to be arranged along base length direction and pour integral the first concrete block and the second concrete block, adjacent first concrete block
Between be embedded one second concrete block, and the section configuration of the first concrete block is trapezoid, the section shape of the second concrete block
Shape is inverted trapezoidal, the construction between the first concrete block and the second concrete block temporarily stitch in be embedded BW water expandable waterstop.
Compared with the prior art, the advantages of the present invention are as follows:
1, the present invention is between the first and second concrete block by being arranged the interim seam of construction, and by the contact surface of the first concrete block
Dabbing removes loose matter, and after rinsing well, smears cement mortar, then be embedded BW water expandable waterstop, finally just carry out second
The pouring construction of concrete block makes the first and second concrete block form one complete continuous whole, and then makes anti-seepage effect more
It is good.
2, construction technology of the present invention is simple, is easy to construct.
Detailed description of the invention
Fig. 1 is sectional view of the asphaltic concrete core wall base construction of the present invention along base axis direction.
Fig. 2 is enlarged drawing at the A of Fig. 1.
In figure: 1-core-wall；2-pedestals；The first concrete block of 3--；The second concrete block of 4--；5-contact surfaces.
Specific embodiment
Below in conjunction with specific preferred embodiment, the invention will be further described, but not thereby limiting the invention
Protection scope.
For ease of description, the relative positional relationship of each component, such as: the description of upper and lower, left and right is according to explanation
Restriction effect is not played to the structure of this patent come what is be described in the Butut direction of book attached drawing.
Embodiment 1:
As shown in Figure 1 and Figure 2, one embodiment of asphaltic concrete core wall basement construction method of the present invention includes the following steps:
1) pedestal concrete block is planned to multiple first concrete blocks 3 and multiple second concrete along the length direction of pedestal 2
Block 4, is embedded one second concrete block 4 between adjacent first concrete block 3, and the section configuration of the first concrete block 3 is positive ladder
Shape, the section configuration of the second concrete block 4 are inverted trapezoidal, the position that the construction of 3 two sides of the first concrete block is temporarily stitched be located at by
Shear smaller and convenient for construction position；
2) pouring construction of all first concrete blocks 3 is carried out along the length direction of pedestal 2, and in adjacent first concrete block 3
Between reserve the second concrete block casting space；
3) it after all first concrete block, 3 pouring constructions, is spaced at least 28 days, be located at interim seam of constructing first is mixed
Solidifying 5 dabbing of soil block contact surface removes loose matter, and after rinsing well, smears cement mortar, then in the first concrete block contact surface 5
It is embedded BW water expandable waterstop, finally carries out the pouring construction of the second concrete block 4, makes the formation of the first and second concrete block 3,4
One entirety.
Wherein, the length of the first concrete block 3 is determined according to construction speed and construction intensity, generally uses 20 ~ 25m,
