holes with shallow, narrow dimensions, long running small ditches - The advantage is that it can dig a narrow hole, dig in an area with underground water, no need to dig more roads up and down for itself and the transport vehicle - The disadvantage is mining with small capacity, time consuming → Choose a backhoe excavator machine: HITACHI ZX200-5G STUDENT: NGUYEN TAM THUONG ID: 17129047 123

pressing: 7.3.1 Choosing construction method: • Due to the relatively large construction load and the lower soil layers have good load capacity, there are many options to lower the pile to the foundation such as: - Piling: has the advantage of being fast and convenient, but it cannot be done because the location of the project is located in a residential area - Pile pressing: can only be done with reinforced concrete slab piles, or steel plate piles used as diaphragm walls - Vibration: is the most practical option for current civil works (no noise, no vibration, good settlement ability), when the construction site does not allow pile driving • Conclusion: - The project is built near a residential area, so to avoid polluting, noise and affecting neighboring works, we choose the option of pressed pile foundation as the most feasible Concept and features: - Pressed piles are piles that are lowered by static energy, without causing momentum to the top of the pile - Advantages of pressed piles: construction does not cause noise, does not cause vibrations Choose pile pressing construction method: - Pre-pressed pile: is the pile that is pressed before construction of the excavation part After pressing to the leveling ground, a section of steel pipe piles with a length of 5m is used to press the pile head to the design depth (-4.2m) compared to the natural ground reinforcement - Construction of reinforced concrete piles of size (400x400) mm, 20m long, including piles of 10m Solid sections are fabricated at the factory and then transported to the construction site 7.3.2 Pile positioning activity: - Before starting the pile pressing work, the contractor needs to build standard landmarks and intermediate control points to accurately locate the pile position on the total construction site - The contractor must preserve the target piles and standard landmarks arranged by surveying staff In case any stake or landmark is moved or lost, surveying needs to replace another pile or landmark Upon completion of all pile work, the Contractor shall make as-built drawings showing the locations of piles that have been made STUDENT: NGUYEN TAM

Pile pressing process: - Stripping all the ground preparation and reasonable pile arrangement - Check the whole pile center by theodolite Use paint to divide the distance on the pile, each line is 1m apart to record the pile history - To avoid eccentricity of the pile center during construction, we use a 0.5m long steel bar that is forbidden to enter the ground, the top of the pile is tied with colored nylon rope to identify the center of the pile - Mounting cranes, frames, counterweights - Position of counterweight as shown in the drawing with each side is 140T • Steps for pressing piles: - Step 1: + Dig a hole about 0.35m deep at the pile tip to position the pile tip in the right position + Crane erects reinforced concrete piles into the press frame + Adjust the pile tip to the right design position, check it with a theodolite and make sure the pile is vertical STUDENT: NGUYEN TAM THUONG ID: 17129047 132 CAPSTONE PROJECT INSTRUCTOR: Assoc Prof TRAN TUAN KIET Figure 7.12: Step of

construction plan: - Must gather piles to days before pressing date (piles are purchased from pile factories) - Arrangement of piles must be placed outside the pile pressing area, the way to transport the piles must be flat, not rough - The pile must have a pre-marked axis to facilitate the use of the calibration theodolite - It is necessary to remove the piles of insufficient quality, not meeting the technical requirements - Before taking the pile for mass pressing, it is necessary to test 1-2% of the number of piles - There must be a full range of geological survey reports and results of static penetration - The layout of the construction site for pile pressing directly affects the fast or slow construction progress of the project The layout of the construction site must be reasonable so that the jobs not overlap and obstruct each other, helping to speed up the construction progress and shorten the construction time • Checking bearing capacity according to material of pile: - After pressing all piles of the project, the piles must be tested for static compression by hiring specialized inspection agencies After the test, there must be full results of the load-carrying capacity, the permissible settlement, if satisfactory, the foundation can be dug for concrete construction STUDENT: NGUYEN TAM THUONG ID: 17129047 135 CAPSTONE PROJECT INSTRUCTOR: Assoc Prof TRAN TUAN KIET
