What are the specifications of Jis A 5354 1993 Concrete Sheet P?
Jis A 5354 1993 Concrete Sheet P is a concrete material that conforms to the Japanese Industrial Standards (JIS) for concrete sheet piles. The specifications of Jis A 5354 1993 Concrete Sheet P include:
Dimensions: The dimensions of the concrete segments vary depending on the type and shape of the sheet pile. The standard types are A, B, C, and D, which have different cross-sectional shapes and sizes. The standard lengths are 6 m, 9 m, 12 m, and 15 m, which can be adjusted by cutting or splicing.
Strength: The strength of the concrete segments is determined by the compressive strength and flexural strength of the concrete material. The standard compressive strength grades are 30 N/mm2, 40 N/mm2, and 50 N/mm2, which correspond to the minimum cube strength at 28 days. The standard flexural strength grades are F-1, F-2, and F-3, which correspond to the minimum modulus of rupture at 28 days.
Reinforcement: The reinforcement of the concrete segments is determined by the type and amount of steel bars or fibers used. The standard types of reinforcement are plain bars, deformed bars, and steel fibers. The standard amount of reinforcement is expressed as a percentage of the cross-sectional area of the concrete segment.
Joints: The joints of the concrete segments are determined by the type and shape of the steel joints used. The standard types of joints are tongue-and-groove joints, hook-and-eye joints, and ball-and-socket joints. The standard shapes of joints are straight joints, curved joints, and corner joints.
What is the installation of Jis A 5354 1993 Concrete Sheet P?
The installation of Jis A 5354 1993 Concrete Sheet P involves the following steps:
Site preparation: The site where the concrete sheet pile wall is to be installed should be cleared of any obstacles and debris. The soil conditions and groundwater level should be investigated and evaluated. The alignment and layout of the wall should be marked and surveyed.
Pile driving: The concrete segments should be transported to the site and lifted by a crane or a pile driver. The segments should be aligned and interlocked with the steel joints according to the design. The segments should be driven into the ground by a hammer or a vibrator until the required depth and penetration are achieved.
Pile cutting or splicing: The concrete segments should be cut or spliced as needed to adjust the length or shape of the wall. The cutting or splicing should be done by a saw or a torch according to the specifications. The cut or spliced segments should be joined by welding or bolting.
Pile testing: The concrete sheet pile wall should be tested for its structural integrity and performance. The testing methods may include static load test, dynamic load test, integrity test, or permeability test. The testing results should be compared with the design criteria and specifications.
How does Jis A 5354 1993 Concrete Sheet P compare with other types of concrete sheet piles?
