Simulative vibration table pile raft type pre-buried component vibration reduction and isolation counter-force foundation and construction method
The invention discloses a simulative vibration table pile raft type pre-buried component vibration reduction and isolation counter-force foundation and a construction method. The counter-force foundation is designed by reference to related national standards and specifications. A medium sand layer is laid, the layer thickness is not smaller than 250 mm, and the particle size ranges from 0.25 mm to 0.5 mm. A water-resisting layer is laid above the medium sand layer, and a plastic cloth connected laying mode is adopted by water-resisting materials. The first layer is poured, pouring is carried out after reinforcement arrangement, and construction depth is 4.14 m. Concrete pouring is carried out on the second layer and the third layer, pouring is carried out after reinforcement arrangement, and construction depth is 1.308 m. Concrete pouring is carried out on the fourth layer, pouring is carried out after reinforcement arrangement, and construction depth is 0.9 m. Improvement is carried out on the basis of a traditional counter-force foundation, the mounting precision requirement of equipment can be met by 0.0005 percent, meanwhile, the influence to surroundings is small when an earthquake simulative vibration table runs in a full load modem, the weight of the foundation is 70 times the total weight of loads, and the maximum vibration of the position 10 m out of the counter-force foundation is about 0.01 g.
