3. Supply process and concrete pile pressing<\/a><\/span><\/h3>\n

\u00a0 \u2013 Transporting reinforced concrete piles, pile driving equipment, and concrete to the construction site. Checking calibration documents and conducting trial runs to prepare for pile driving.<\/span><\/p>\n

\u00a0 - Proceed Pile<\/a>, technical staff of the customer and Le Thy company jointly supervise the pressing process and record the pile pressing log for each pile center. The project is completed, the two parties conduct acceptance of pile pressing at the construction site.<\/span><\/p>\n

\u00a0 \u2013 Based on the acceptance of the work, both parties will proceed with the contract termination.<\/span><\/p>\n

\u00a0 \u2013 With the above closed-loop process, LE THY Construction Company will provide customers with the highest level of peace of mind and trust. At each stage of the work, customers will work with the highest-level management staff of the department to make quick, accurate decisions, shorten time, and bring high economic efficiency to both customers and our company..<\/em><\/span><\/p>\n

5. Sequence of pile pressing construction<\/h3>\n

\u00a0 \u2013 The crane will install the base frame into the correct design position.<\/span><\/p>\n

\u00a0 \u2013 Counterweights are placed on the base frame.<\/span><\/p>\n

\u00a0 \u2013 Use a crane to install the press frame onto the base, accurately positioning and adjusting it so that the press frame stands upright.<\/span><\/p>\n

Construction steps for a pile center:<\/span><\/strong><\/em><\/p>\n

Step 1<\/span>: Survey to determine the position of the pile center in preparation for pressing using a marker pile to mark the center of the pile<\/span><\/p>\n

Step 2<\/span>: Use the crane to move the pressure rack into the correct position of the marker stake placed above. After placing the press rack, use a surveying machine to adjust the verticality and balance of the press rack and install the necessary equipment for the press such as oil pipes, etc. to assemble the welding machine.<\/span><\/p>\n

Step 3<\/span>: After securely jacking up the press, place the counterweight on the press rack using the crane.<\/span><\/p>\n

Step 4<\/span>: Use an anchor cable to tie the pile to ensure it is secure, then use a crane to lift each pile segment into the position of the pressing rack cage, each pile segment is connected to each other by welding, finishing pressing when it has pressed to the correct specifications. design issues given.<\/span><\/p>\n

Step 5<\/span>: Check the verticality of the pile in both directions with a total station before pressing. Proceed to press the pile at a speed of 1cm\/s until the pile tip is 200mm above the ground then stop.<\/span><\/p>\n

Step 6<\/span>: Move the guide pile up and crane the middle section of 9m to install it on the press bar and tightly install the pile head into the guide tower, then weld the two pile sections together. Check the verticality of the pile in both directions with a total station before pressing. Proceed to press the stem section at a speed of 1cm\/s until the pile tip is 200mm above the ground then stop.<\/span><\/p>\n

Step 7:<\/span> Use negative pressure piles to continue pressing until the pile tip reaches the design depth and the pressure force is not less than Pmin<\/span><\/p>\n

Step 8<\/span>After driving one pile, slide the pile driving rig on the base frame to the next position to continue driving. While driving piles on the first foundation, use a crane to lift the second base frame into position for the second foundation pit.<\/span><\/p>\n

\u00a0 After finishing pressing one foundation, move the entire pressing frame system to the second base frame that has been placed in advance in the second foundation hole. Then crane the counterweight from base frame 1 to base frame 2.<\/span><\/p>\n

\"\"<\/p>\n

Stop pressing piles is applied in the following cases:<\/em><\/strong><\/p>\n

\u00a0 \u2013 The pile tip reaches the design depth and the pile head driving force is not less than Pmin \u00a0<\/sub>\u00a0(by design).<\/span><\/p>\n

\u00a0 \u2013 If the pile tip has not reached the design depth, stop pile driving when the pile head driving force is not less than Pmax\u00a0<\/sub>\u00a0(by design)<\/span><\/p>\n

\u00a0 \u2013 If the pile tip reaches the design depth and the pile driving force is less than Pmin<\/sub> then pile pressing continues until the pressure reaches P .min \u00a0<\/sub>\u00a0(by design)<\/span><\/p>\n

\u00a0 The construction unit will notify the Supervision Consultant, the Investor, and the Design Consultant when there is a difference in the value of the pressure force and the pile driving depth to have a solution, and when necessary, conduct additional soil surveys. Supplement and conduct experiments to have a basis for conclusions.<\/span><\/p>\n

\u00a0 Piles that are excessively inclined (greater than 1%), piles that are partially driven due to encountering foreign objects such as sand pockets or unusually hard clay layers, or piles that are broken, must all be handled by pulling them up and re-driving them or driving additional new piles (as specified by the design).<\/span><\/p>\n

\u00a0 Use appropriate drilling methods to break up foreign objects, penetrate through sand pockets, hard clay layers, etc.<\/span><\/p>\n

\u00a0 When the pressure has just reached the design value, the pile cannot go down anymore, while the pressure on the pile continues to increase beyond the maximum pressure (Pep<\/sub>)max<\/sub> then before stopping the pressure, use valve to keep the maintaining force (Pep<\/sub>)max<\/sub> within 5 minutes.<\/span><\/p>\n

\u00a0 In case the press does not have a retaining valve, it must be pressed three to five times with the pressure (Pmax<\/sub>).<\/span><\/p>\n

\u00a0 Finish pressing one pile.<\/em><\/span><\/p>\n

\u00a0 In addition to supply and construction of pressing square pile<\/a>, Centrifugal round pile<\/a> Le Thy Construction Company Limited also supplies and constructs squeezing Larsen<\/a> by hydraulic robot, construction kingpost shoring<\/a>, bored pile drilling<\/a><\/em><\/span><\/p>\n
