Abstract

The invention belongs to the technical field of constructional engineering and particularly relates to a foundation dynamic compaction construction method. The foundation dynamic compaction construction method includes the steps that firstly, the ground surface is cleaned; secondly, earthwork backfilling is conducted; thirdly, local compaction is conducted; fourthly, full compaction is conducted; and fifth, checking is conducted after compaction, wherein various test data and test records in the trial compaction process are checked, when the test data and the test records do not meet design requirements, supplementary compaction should be conducted or other effective measures should be taken, the quality of the foundation can be checked only after a certain time interval after trial compaction construction is over, earthwork tests and dynamic penetration tests are conducted in time after trial compaction is completed, and test parameters are collected in time. By means of the foundation dynamic compaction construction method, the compaction frequency is accurately regulated, a sensor is introduced for analyzing construction data in real time, the foundation dynamic compaction construction method is very suitable for being used and popularized in subtropics monsoon climate zones, the construction period can be effectively shortened, and the construction quality is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a foundation dynamic compaction construction method. Background technique [0002] The construction area has a subtropical monsoon climate, with an annual average temperature of 16.9°C, with an average temperature of 5.2°C in January and 27.3°C in August, and an average annual rainfall of 1,150 mm. The main characteristics of the climate are: early spring, hot summer, cool autumn, warm winter, four distinct seasons, rain and heat in the same season, and simultaneous sunlight; long frost-free period, suitable light, abundant rainfall, mild climate, suitable for the development of agriculture, forestry, animal husbandry, and fishery However, it is rainy in autumn, foggy in winter, less frost and snow, and the spatial and temporal distribution of precipitation varies greatly. Disastrous weather such as summer drought, autumn rain, wind, and hail often oc...
