Abstract

The invention relates to a bending test platform and method for a prestressed concrete sheet pile. The test platform comprises a test piece, a concrete platform, a loading frame, a jack and a load distribution beam, wherein the loading frame consists of two rows of upright posts and a reaction beam erected between the two rows of upright posts; the upright posts are connected with the reaction beam through bolts; the bottoms of the upright posts are buried on the concrete platform; the test piece is supported on the concrete platform through a support liner plate; the load distribution beam is vertical to the reaction beam; the jack is arranged between the reaction beam and the load distribution beam; the load distribution beam is supported on the test piece through force transferring brackets arranged at the two ends of the load distribution beam; the test piece is a prestressed U-shaped concrete sheet pile; and the force transferring brackets are matched with the section of the U-shaped concrete sheet pile, and are clamped on the U-shaped concrete sheet pile. The test platform has the advantages of simple structural form, convenience for installation and test loading and the like, and can be widely applied to bending resistance test of test pieces of U-shaped sections and similar sections.

Description

technical field [0001] The invention relates to a test stand and a test method thereof, in particular to a bending test stand and a test method thereof. Background technique [0002] Prestressed U-shaped concrete sheet pile is a new type of prefabricated concrete retaining pile. With its unique U-shaped structural section, it increases the thickness of the structural section and the width of the retaining soil. It has excellent bending resistance and has a large retaining section, With the advantages of good mechanical performance and high cost performance, it can be widely used in engineering fields such as water conservancy, municipal administration, ports, docks, industrial and civil buildings, roads, and railways. The most important indicator of prestressed U-shaped concrete sheet piles is the flexural performance. Therefore, performing a flexural test on the produced sheet piles to verify their flexural performance is an important indicator for testing the quality of p...
