Embodiment 1

[0029] Embodiment 1: see figure 1 , 2, a detection box for detecting ice thrust and ice pullout damage of water conservancy buildings due to freezing of reservoirs, used to detect ice thrust and ice pullout force of a test material plate 6 made of rigid materials, including ice Liquid sink 1, the top and vertical side of the sink 1 are designed to be open, the top opening of the sink 1 is equipped with a top plate 2, and the opening of one side of the vertical surface is provided with a test material plate 6, and the test material plate 6 is fixed by The plate 3 is fixed on the water tank 1, and the top plate 2 and the surrounding of the fixed plate 3 are sealed with the water tank 1. The top plate 2 and the test material plate 6 are equipped with horizontally and vertically arranged multi-row and multi-column pressure sensors 4, pressure sensors 4 Communication connection with the signal receiver 5 through the data transmission line, the top opening of the detection box 1, a...

Embodiment 2

[0031] see figure 1 , 2 , a detection box for detecting ice thrust and ice pull damage of water conservancy buildings due to freezing of reservoirs, used to detect ice thrust and ice pull force of test material plate 6 made of elastic material, this embodiment and embodiment 1 The difference is that: the test material plate 6 is provided with nine passing holes I10 in three rows and three columns, wherein, two passing holes I10 are selected in each row, and there are six passing holes 10 in total, and the distance between the bottom of the six passing holes I10 is tested The material plate 6 is 2-5 mm away from the side of the water tank 1. Pressure sensors 4 are installed in the six passage holes I10. The detection end of the pressure sensor 4 is in contact with the bottom of the passage hole I10. The detection end of the sensor 4 is in contact with the fixed plate 3 .

Embodiment 3

[0033] see figure 1 , 2 , a detection method for detecting the ice thrust of water conservancy buildings and the detection box of ice pull damage caused by freezing of reservoirs. The test material board in this embodiment is polyurethane rigid foam, and the ice resistance it withstands under the condition of slow cooling is tested. Thrust and anti-ice pull damage

[0034] Specific detection method:

[0035] The size of the water tank 1 is 30cm*40cm*40cm (length*width*height). The water tank 1, the top plate 2, and the fixing plate 3 are all made of stainless steel with a thickness of 5mm. The test material plate 6 is polyurethane rigid foam (thickness 8cm, density 70Kg / m2) sprayed with polyurethane waterproof layer (thickness 1mm) on the outer layer 3 ).

Abstract

The invention relates to a detection box used for detecting the ice thrust and ice pulling destruction of reservoir icing for water construction and a detection method thereof, and belongs to the field of water construction prevention. The detection box comprises a water tank filled with liquid capable of icing, wherein the top and one vertical side of the water tank are of an open design; an opening in the top of the water tank is provided with a top plate; an opening of the vertical surface of one side is provided with a test material plate; the test material plate is fixed on the water tank through a fixing plate; the periphery of the top plate and the periphery of the fixing plate are both sealed with the water tank; the top plate and the test material plate are respectively provided with multiple lines and rows of pressure sensors which are horizontally and vertically arranged; the pressure sensors are in communication connection with a signal receiver through a data transmission line. According to the detection box, an ice thrust experiment can be carried out in a laboratory, an ice pulling destruction situation is qualitatively detected, so as to verify whether a test material can resist the ice thrust and ice pulling destruction or not, detection data is accurate, and construction verification does not need to be carried out in a practical water conservancy project.

Description

technical field [0001] The invention relates to a detection box and a detection method for detecting ice thrust and ice pull damage of water conservancy buildings caused by icing of reservoirs in a low-temperature environment, belonging to the field of protection of water conservancy buildings, that is, a method for detecting ice thrust of water conservancy buildings caused by icing of reservoirs As well as a detection box for ice-pulling damage and a detection method thereof. Background technique [0002] During the winter water storage operation of reservoirs in cold regions, the water surface keeps freezing and the volume expands. The inward extrusion phenomenon of water conservancy expansion on the surface of water conservancy buildings is the phenomenon of ice push, and the resulting extrusion force is called ice thrust. However, if the water storage capacity of the reservoir is higher than the water consumption for power generation, the water level will rise, causing ...
