Embodiment 1

[0045] Embodiment 1: This example is applied to the strip foundation under the wall, see the attached figure 1 , 2 , 3, 4, 5. The geocell reinforced rubber particle-sand mixture rock-soil composite shock-isolation layer and belt structure applied to the strip foundation under the wall of the present invention have the following characteristics:

[0046] a. The geocell reinforced rubber particle-sand mixture rock-soil composite seismic isolation layer and belt structure include the composite seismic isolation cushion (3) laid between the foundation (1) and the strip foundation (5) under the wall, and the filling A composite seismic isolation belt (6) built between the foundation (1) and the strip foundation (5) under the wall.

[0047] b. The composite shock-isolation cushion (3) is composed of a geocell (9) and a rubber particle-sand mixture (10). The geocell (9) is a geotechnical material that can be purchased in the market. After the geocell is deployed, it becomes a thre...

Embodiment 2

[0058] Embodiment 2: This embodiment is applied to the independent foundation under the column, and the corresponding upper structure can be a frame structure, a bottom frame or an inner frame structure, see Figure 7 As shown, the basic structure of this embodiment is the same as that of Embodiment 1. The difference is that the geocell reinforced rubber particle-sand composite shock-isolation cushion (3) is laid under the independent foundation (15) under the column.

Embodiment 3

[0059] Embodiment 3: This embodiment is applied to the pile-cap foundation. When the bearing layer of the foundation is deep or the foundation is a weak foundation and the pile-cap foundation must be used, if the superstructure is a multi-storey building and there is no special requirement for the overturning resistance of the foundation, the geotechnical method described in the present invention can still be applied. Cell-reinforced rubber particle sandstone-soil composite isolation layer and belt for base isolation, see Figure 8 As shown, the basic structure of this embodiment is the same as that of Embodiment 1. The difference is that the geocell reinforced rubber particle-sand composite shock-isolation cushion (3) is laid on the entire area of ​​the pile cap (16) and the geocell reinforced rubber particle is filled around the foundation pit - Sand composite seismic isolation belt (6).

Abstract

The invention discloses a geocell reinforced rubber particles-sand mixture compound shock insulation layer and strip, which belongs to the technical field of structure shock absorbing and shock insulation, and is mainly used for solving the problem of serious destructions of a general multi-story building in an earthquake. According to the invention, the compound shock insulation layer and strip are manufactured by the filling and layered punning of rubber particles-sand mixture mixed by an optimal mix proportion in geocell inner layers; the shock insulation layer is arranged at the bottom of a base; shock insulation strips are arranged on two sides of the base; the geocell is a geotechnique material which can be bought easily and is low in cost; the rubber particles are rubber fragments with certain particle diameters, and are obtained by the mechanical fragmentation of junked tires; the sands are ordinary river sands used for construction. The shock insulation layer and strip have good shock insulation effect, low cost, environmental protection, simple structure, and convenience in construction, and is generally suitable for the compound shock insulation technology of the multi-story building; the technical scheme can effectively solve the problems of bad shock resistance and serious destructions of a low story dwelling in a town, and has a wide application prospect.

Description

technical field [0001] The invention relates to a geocell reinforced rubber particle-sand mixture composite shock-isolation layer and belt structure, relates to the field of building structure, geotechnical engineering and structural shock-isolation, and belongs to a kind of good shock-isolation effect, low cost, green and environmental protection , Simple structure, convenient construction, suitable for multi-storey building foundation isolation, dynamic machine foundation isolation and high-speed moving load subgrade isolation composite isolation structure. Background technique [0002] The main principle of base isolation is that by setting an isolation layer between the superstructure and the foundation, the movement, deformation and energy consumption caused by the earthquake mainly occur in the isolation layer, so that the earthquake action on the upper structure is greatly reduced, so as to achieve The purpose of protecting the superstructure. There are many existing...
