Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, a concrete hydrostatic penetration pressure test device under temperature-changing conditions includes a test device system, and the test device system includes a test box, and a pressure valve 4 communicating with the inside of the test box is provided on the outside of the top of the test box. Pressure gauge 3 and decompression valve 5, the pressure valve 4 is connected to an external air press 1 through a high-pressure air pipe 2, and the pressure in the test box is increased by connecting the external air press 1. The decompression valve 5 is used to reduce the pressure in the test box during use. One of the sidewalls of the test box is a steel sealing test plate 10, and the steel sealing test plate is provided with a conical hole 6 communicating with the inside of the test box, and the large end of the conical hole 6 is located...

Abstract

The invention provides a device for testing hydrostatic seepage pressure of concrete under a temperature-variable condition. A pressure valve, a pressure meter and a reduced pressure valve are arranged at the top end of a testing tank, the pressure valve is connected with an external air pressure machine through a high-pressure air pipe, one side wall of the testing tank is a steel sealed test board, a conical bore is formed in the steel sealed test board, and a big end of the conical bore is located in the testing tank; and an air bin and a water bin are arranged in the testing tank, the air bin is located at the upper part of the water bin and is communicated with the water bin, heating bars are arranged in the water bin, a thermometer is arranged on the outer wall of the water bin, a water return valve is arranged on the side wall of the bottom of the water bin and is connected with a first water inlet valve on an external cold water circulating tank through a water return pipe, and a water outlet valve on the cold water circulating tank is communicated with a second water inlet valve at the top of the air bin. The device can be used for testing the seepage pressure of the concrete in a temperature-variable environment and is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to concrete permeability testing, in particular to a hydrostatic penetration pressure testing device for concrete under variable temperature conditions. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to the cement concrete obtained by mixing cement with cement as cementing material, sand and stone as aggregate, and water (may contain admixtures and admixtures) in a certain proportion, also known as ordinary concrete. Concrete, which is widely used in civil engineering. There are a lot of pores inside the concrete, which leads to the high permeability of the concrete itself. In some wading civil engineering projects, higher requirements are put forward for the permeability of concrete, such as: hydropower stations, seaport projects, underground space projects, etc. Commonly used m...
