8.0 DEEP AND SPACE TO UNDERGROUND WORKS

The depth of pipe burying when crossing irrigation canals or ditches is determined based on API RP 1102 standard, input parameters are pipe wall thickness, tunneling depth, parameters of roads and operating vehicles. Check the pipe's stress against allowable stress and weld fatigue against the weld fatigue limit to ensure that the pipe is not damaged or destroyed during operation.

9.0 CONSTRUCTION METHODS AND DRILLING TECHNICAL SOLUTIONS

9.1 SURVEY

Construction arrangement survey

The construction team, the survey team discussed in reality the ground characteristics, existing obstacles (underground lines, cables, sewers, ...) to determine the location of the drill, the welding position. pipe assembly, towing preparation plan, construction plan for gathering of equipment and materials, possible obstacles and propose solutions to speed up the progress (if necessary).

Thus, it can be seen that the difficulty mainly comes from natural conditions: ground, geographical location, weather. To overcome these difficulties and speed up the progress, the contractor must comply with the following criteria:

1. Mobilizing optimal resources for all stages.

2. Reasonably allocating resources for smooth coordination between the construction sites, local authorities, functional agencies and the Investor, not creating downtime during the construction process.

3. Strictly control, find out potential risks, focus on immediate treatment to prevent these potentials from developing into problems.

9.2 MACHINE EQUIPMENT AND HUMAN RESOURCE

Based on the survey data, Minh Phuong has selected the appropriate equipment and materials to gather to the project. The right and enough selection ensures efficient construction, on schedule and minimizes costs.

Personnel implementing the project must ensure that they have been trained in safety and have specialized certificates relevant to the field in charge.

9.3 PREPARATION OF DRILL work

Using electronic total stations to determine the scope of the construction area in the field.

There are 10 positions to drill through irrigation canals and ditches:

1st underground drilling location - Pipe crossing Vam Ho bridge from pile A25 - A31, HDPE pipe OD560, L = 105m.
