This project is located south of Wuhuan Road in Xuzhou High-Tech Industrial Development Zone, west of National Highway 206, and east of the Jintong Railway. The site is currently undergoing backfilling and has met the "three connections and one leveling" requirements. The design employs the dynamic compaction method for foundation treatment. The northeastern part of the factory area requires the use of dynamic compaction to treat the foundation to meet the design requirements for the foundation.

Cone Penetration Requirements
(1) After reinforcement, the reinforced foundation must be inspected. If the inspection results do not meet the design and specification requirements, the foundation must be treated or re-compacted.
(2) Strictly adhere to the design for construction to ensure no missed or insufficient compaction.
(3) When the compaction location is less than 20 meters away from existing buildings, treatment measures should be taken in accordance with the requirements of the monitoring unit.
(4) Single Point Compaction Construction Steps
Prior to the single-point dynamic compaction work, draw the layout plan of compaction points for each zone based on the design principles. The steps for the single-point dynamic compaction work are as follows:
Clear and level the construction site.
②Mark the first compaction point locations and measure the site elevation.
③ The compaction hammer is positioned at the compaction point, ready on the pile driver.
④ Measure the initial and final elevation before and after compaction.
⑤ Hoist the tamper to the predetermined height, activate the unhooking device, allowing the tamper to fall freely, lower the hoist, and measure the height of the tamper's top; if the tamper is found to be tilted due to the inclined bottom of the pit, the bottom of the pit should be leveled promptly.
⑥ Repeat the previous step, and strike the compaction point according to the specified number of blows and control standards. When the compaction pit is too deep, lifting the hammer becomes difficult, there is no obvious bulging, and it has not yet reached the control standards, it is advisable to backfill the pit to the level of the pit top and continue the blows.
Step 7: Move to the next compaction point, repeat steps 3 to 6, and complete the first round of compaction for all points.
⑧ Level the compaction holes with a bulldozer and measure the site's elevation.
After the specified interval, sequentially complete all the tamping passes as mentioned above; then, use low-energy full tamping to compact the loose soil on the site surface, and measure the elevation of the site after tamping.
