Construction method of industrial building shock absorption foundation

Abstract

The invention discloses a construction method of an industrial building shock absorption foundation. The construction method is characterized by comprising the following construction steps of (1) mounting a hydraulic valve on a prefabricated support column, and then pressing the prefabricated support column into a soil body; (2) excavating the soil body to a designed bottom elevation, paving geotechnical cloth on an arch-shaped base, and enabling raft plate and concrete inverted beam formworks to adopt brick moulding beds; (3) binding steel bars of a raft plate and a concrete inverted beam, erecting the raft plate and concrete inverted beam formworks, and reserving shock absorption holes in the raft plate; (4) pouring concrete of the raft plate and the concrete inverted beam; (5) placing shock absorption blocks in the shock absorption holes, placing the shock absorption blocks on supporting columns, paving shock absorption materials on the shock absorption blocks, and paving steel plates on the shock absorption materials for sealing; (6) arranging buttresses on the steel plates at the shock absorption holes; (7) arranging a bearing frame on the buttresses; and (8) installing industrial equipment on the force bearing frame. The construction method is good in shock absorption effect.

Description

technical field [0001] The invention relates to the construction field, and more specifically relates to a construction method for shock-absorbing foundations of industrial buildings. Background technique [0002] In industrial buildings, heavy loads such as industrial equipment often have continuous and severe vibration loads. When acting on the foundation soil, its weight is borne by both the soil particles in the foundation and the pore water in the foundation. When the saturated soil is subjected to vibration loads Under the action, the soil particles in the foundation will appear due to the different sizes of the soil particles, and the displacement speed of the soil particles will be different. The soil particles that are originally closely connected to each other, under the vibration, there will always be a distance between them due to their respective subsidence displacement speeds. Not the same, sometimes the soil particles will jump up and down and leave each other...

[0002] In industrial buildings, heavy loads such as industrial equipment often have continuous and severe vibration loads. When acting on the foundation soil, its weight is borne by both the soil particles in the foundation and the pore water in the foundation. When the saturated soil is subjected to vibration loads Under the action, the soil particles in the foundation will appear due to the different sizes of the soil particles, and the displacement speed of the soil particles will be different. The soil particles that are originally closely connected to each other, under the vibration, there will always be a distance between them due to their respective subsidence displacement speeds. Not the same, sometimes the soil particles will jump up and down and leave each other in a suspended state. When the soil particles are connected, they have the effect of mutual force transmission. Once suspended, the force transmission effect will be lost. At this time, the vibration load of industrial equipment can not help but lose the force transmission effect. The soil particles are responsible for the pore water in the foundation. The water has no shear strength and has no ability to withstand vibration loads. Therefore, the uneven subsidence of the foundation soil after liquefaction causes industrial buildings to lose their support and cause large-scale subsidence.
