Embodiment Construction
[0016] Concrete engineering practice and characteristics of the present invention will be further described below in conjunction with the accompanying drawings, so that those skilled in the art can understand:
[0017] Such as figure 1 with figure 2 As shown, the embodiment of the present invention is a composite seismic isolation system of row piles-isolation trench, which specifically includes the isolation trench body 5 and two rows of fly ash concrete pipe piles on the outside of the trench body as the seismic isolation row piles 3, wherein the trench The interior of the body includes U-shaped steel sheet piles 1, a top crown beam and a top inner support arranged on the crown beam.
[0018] The specific information of seismic isolation row pile 3, that is, fly ash concrete prefabricated pipe pile, is as follows: outer diameter 400mm, concrete strength C30, main reinforcement diameter can be 12-22mm, the number of roots should not be less than 8, and the net protective la...

Abstract
The invention belongs to the technical field of building earthquake prevention and specifically relates to an ancient building seismic isolation barrier. The ancient building seismic isolation barriercomprises seismic isolation groove bodies distributed around an ancient building; two rows of seismic isolation row piles are perpendicularly driven into the external sides of the seismic isolation groove bodies downwards; the seismic isolation row piles are hollow tubular piles; and the seismic isolation row piles adopt steel reinforcement coal ash concrete precast tubular piles. The layout formof the seismic isolation row piles adopts intensive layout; the apertures of the seismic isolation row piles are less than the distances between the adjacent seismic isolation row piles; and the seismic isolation groove bodies are filled with foam concrete blocks. As the ancient building seismic isolation barrier is a row pile-seismic isolation groove composite seismic isolation system, adverse effects of vibrations with different frequencies and different forms on a protected building is weakened, the construction and building cost is low, and meanwhile, the environmental suitability of thecomposite seismic isolation system is improved, and the broad application range is realized.
Description
technical field [0001] The invention belongs to the technical field of building anti-seismic technology, and in particular relates to an ancient building anti-seismic barrier, in particular, it can have a good anti-seismic effect on both artificial vibration and earthquake vibration. Background technique [0002] With the continuous development and progress of human society, the problems caused by vibration are becoming more and more extensive and the number is increasing day by day. Because the vibration generated by our production and life affects our life all the time, it also threatens my country's extremely high cultural and historical value and Many ancient buildings of great cultural significance. Earthquakes, in particular, are vibrations that propagate from the seismic source to all directions, and refer to elastic waves that radiate from the source to the surroundings. According to the propagation mode, it can be divided into three types: longitudinal wave (P wave)...
