The shear wall 1 is along the in a row distribution of domatic trend, and each row's amount of shear walls, spacing are according to site condition and specifically Engine request determines that the longitudinal axis of shear wall 1 is consistent with slope aspect.
The upper end of Vierendeel girder 2 be located at same level height, Vierendeel girder 2 divide for crossbeam and longeron, its crossbeam direction it is vertical Slope aspect is distributed, and longeron direction is distributed along slope aspect.
A kind of construction method of suitable slope shear wall building development platform of the present invention, comprises the following steps:
1st, the position of shear wall is determined, then excavates groove along slope aspect in shearing wall chase section;
2nd, after channel excavation, according to the construction technology of diaphragm wall, the steel reinforcement cage tied is put into groove, according to work Range request pours the concrete of design height, and the wall of below ground pours to be poured according to the construction technology of diaphram wall Build, wall more than ground is poured according to the construction technology of shear wall, forms integral embedded type shear wall, shear wall top The splice of the reserved certain length in Vierendeel girder position is being poured in advance;
3rd, after shear wall is formed, according to the construction technology of Vierendeel girder, pre- in shear wall upper end pours position placement bundle Good steel reinforcement cage, Vierendeel girder steel reinforcement cage are connected with the splice that shear wall top is reserved using welding manner or bind mode, According to engine request casting concrete, Vierendeel girder is formed, the splice of certain length is reserved on Vierendeel girder top;
4th, after Vierendeel girder is formed, according to the construction technology of platform, the steel reinforcement cage tied, platform are disposed at the top of Vierendeel girder Steel reinforcement cage is connected with Vierendeel girder top reserved steel bar joint using welding manner or bind mode, then casting concrete, is formed Integral-type platform.
The shear wall construction process uses hopping sequence method, i.e., along sequence construction odd number shear wall, then it is even along sequence construction Number shear wall.
Compared with prior art, the beneficial effects of the present invention are:
1st, it is more much smaller than directly excavation, rectangular-shaped excavation along the section of domatic trend, therefore side slope disturbance of constructing is small; Simultaneously using hopping sequence method construction shear wall, the level of disruption of side slope can be preferably minimized;
2nd, shear wall excavation volume is small, therefore quantities is small, construction is simple, and engineering cost is low;
3rd, shear wall is larger along slope aspect width, can provide very high vertical bearing capacity;
4th, the arrangement of reinforcement in shear wall can be provided along the larger horizontal resist forces of vertical wall, ensure superstructure in earthquake etc. no Stability under the conditions of profit;
5th, shear wall can also resist side slope downward sliding power to a certain extent, be advantageous to the stabilization of side slope;
6th, platform upper can with building constructions thing, can side slope effectively utilized.
