How to set up the temporary structure of the external structure of the balcony on the two structure
Main projectCast - in - place main beam, board, column, stair - prefabricated board is installed - brick wall - door window hole is reserved, water and electricity Guan Xianyu is buried.
Earthwork:The pile cap is shallow, the foundation beam and sand filling quantity is less, the depth is to the outdoor floor 1.5m, so the earthwork construction adopts the mechanical leveling site construction scheme. Backfill soil must be layered compaction, density of not less than 0.9. Construction lap should be compact, interval time should not be too long, in case of rain water, the construction of various types of pipe should be synchronized with the foundation construction.
Foundation engineering:Square - hole excavation pile - pile - reinforced concrete beam - based backfill. Pile by manual drilling, artificial trolley, concentrated heap of residual soil, automobile Sinotrans earthwork project, the allowable deviation of hole diameter of pile are as follows: 800cm, vertical aperture offset, 10cm < 1%, along the axis, vertical axis direction 7cm.
Construction scheme and technical measuresAccording to the actual situation of the 1.1. design drawings and combined with the content of the project construction site, the project arrangement of small water method construction work construction, construction division order: positioning line - based project main project - - - Roof Engineering Decoration Engineering hydropower installation engineering - completion of cleaning, acceptance, delivery. Positioning of engineering survey according to the plan and the total construction plan.
