H-type PC pile
Wall materials for retaining structures using precast PC components that do not require temporary earth retention.
The "H-type PC pile" is a prestressed concrete member with an H-shaped cross-section manufactured in a factory, and it is a construction method for building retaining walls by continuous driving using a three-point pile driver. During construction, it is used as a temporary retaining wall, and during the permanent phase, it is used as the completed structure. The cross-sectional dimensions are available in three types: width 1070(mm) × height 540, 640, 740(mm), and the design standard strength of the concrete is 70(N/mm²). 【Features】 ■ No need for temporary retaining walls ■ Self-supporting wall heights of up to approximately 8.5(m) are possible ■ Rigid connection with base and top slabs is possible ■ Leakage suppression effect for groundwater and other water ■ Drainage effect for rainwater and other sources ■ Low noise and low vibration construction method ■ Shortened construction period on site *For more details, please refer to the PDF materials or feel free to contact us.
basic information
【Other Features】 - Manufactured in a factory with thorough quality control, ensuring high quality and improved durability. - In the event of unexpected obstacles or boulders during construction, the piles can be temporarily pulled out, allowing for the removal of obstacles or boulders, and reinstallation is possible. - Construction is feasible even on hard ground such as bedrock by using auxiliary methods. - Due to the high bending rigidity of the components, it is possible to suppress displacement. 【Certification and Registration】 - (Public Interest Incorporated Foundation) Civil Engineering Research Center, Construction Technology Review Certificate No. 0803 - Tokyo Metropolitan Government Construction Bureau, New Technology Information Registration No. 1801009 *For more details, please refer to the PDF materials or feel free to contact us.
