Embodiment Construction

[0016] The present invention will be further described below in conjunction with embodiment in the accompanying drawings:

[0017] figure 1 As shown, the stiffened belt deformation test device of the present invention includes a grooved housing 1, and the grooved housing 1 is attached with a grooved flexible body 2 directly formed in the groove thereof, and the flexible body 2 is made of rubber or composite rubber . The groove flexible body 2 is embedded with a sensitive element 3 made of conductive rubber composite material. A copper electrode 6 is provided at both ends of the sensitive element 3. The tails of the two copper electrodes 6 are connected with a data test line 7. The data test The wire 7 is led out through the wire hole 8 provided at one end of the groove housing 1, and is connected with the tester. figure 2 shown. The bottom of the groove housing 1 is fixed with a bottom plate 4 by bolts. The groove housing 1 and the bottom plate 4 can be made of metal or ha...

Abstract

The invention relates to a reinforced belt deformation testing apparatus for testing the strain of the reinforced belt utilizing the compressive resistance effect of conductive rubber composite material and the testing method thereof. The apparatus mainly comprises a grooved casing, a grooved flexible body is attached in the grooved casing; a sensitive element is inserted in the grooved flexible body; copper electrodes are disposed on both ends of the sensitive elements; data testing wires are connected on the tails of the copper electrodes; a bottom board is fixed on the bottom of the grooved casing; the grooved casing is connected with the bottom board to enclose the reinforced belt to force it deformable only in the length direction; the lower surface of the sensitive element is stick tightly on the upper surface of the reinforced belt to be able to deform synchronously; and the strain value of the reinforced belt can be obtained by measuring the resistance change of the sensitive element. The invention solves the problem of large tensile deformation of the reinforced belt in test, achieves the advantages of simple structure, easy manufacturing, convenient installing, precise and stable test data, reliable properties and good effect, and has wide practicability.

Description

Technical field: [0001] The invention relates to a reinforced strip deformation testing device and a testing method thereof, and is especially suitable for the large deformation test of the reinforced strip in the reinforced soil cushion layer and the reinforced soil retaining wall. Background technique: [0002] At present, geotextiles are used in the construction of highways, railways, water conservancy, civil construction and other projects for the purpose of changing soil properties, stabilizing soil structures, and ensuring and improving building quality. Reinforced strips are widely used as reinforcement materials in reinforced soil cushion and reinforced soil retaining wall projects. At present, the reinforced strips used in reinforced soil engineering at home and abroad can be divided into two categories: one is steel strips, such as stainless steel flat steel strips, galvanized flat steel strips, etc., which have high strength and small elongation; One type is flex...
