Comprehensive analysis of the above highway on-site work experience and testing conclusions, you can obtain the following results.
(1) From the experimental data information of the earthwork backfill stone section on the spot, the subgrade is filled and reinforced by the compaction operation of the strong file 18 hammer to 24 hammer, the surface compactness of the earthwork backfill subgrade can reach more than 96%, the compactness within the 1m category can be 95%, and the reasonable compaction depth can reach 1m-3m, which can achieve the product quality regulations of the construction process. Filled subgrade, especially the stone square high filled subgrade subgrade, is used to carry out hierarchical reinforcement by Rapid Impact Compaction, which can bring about a certain practical effect of surface crushing and deep squeezing, which is very beneficial to improving the stability of the subgrade and reducing the settlement of the foundation after work.
(2) Can be integrated into the general drainage engineering back of the higher compaction regulations, from the scene culvert side backfill soil experiment, through the strong file 12 hammer ramming reinforcement operation, the foundation settlement capacity to achieve 12.3cm, so that the back of the back of the soil are compact, reduce the foundation settlement after work.
(3) At this stage, there is a certain difference between the HC type Rapid Impact Compaction and the general strong ramming foundation machinery and equipment in the application field, ramming kinetic energy, and the deep layer of harm, and the actual use of equipment needs to be carried out according to the standards of the working conditions on the spot and the construction quality regulations; As a new type of high-efficiency compaction machinery and equipment, Rapid Impact Compaction has high ramming kinetic energy and great harm. Flexible and maneuverable characteristics.
Rapid Impact Compaction can be integrated into the necessity of highway infrastructure construction, such as drainage engineering backfill soil, tunnel substrate solution, rock filling subgrade, filling and digging junction, "chicken claw ditch" and other unique roads in highway construction, especially suitable for the narrow working surface or the current compaction machinery and equipment can not be close to the unique road.
The specific processing technology of Rapid Impact Compaction used in subgrade engineering projects is similar to that of strong rammed foundations, but it is more flexible and maneuverable than strong rammed foundations, and has very good utilization and adaptability on the spot for operations with limited standards.
