The invention discloses a construction method for repairing disjoint of a water turbine volute by hydraulic structure disjoint filling (HSDF) silicone adhesive, and belongs to the technical field of hydraulic engineering construction. The method comprises the following steps: preparing construction, checking volute disjoint and determining a construction range, arranging injection hole positions,manufacturing injection holes, testing compressed wind, mounting injection equipment, controlling injection pressure, mounting an injection pipe, preparing the HSDF adhesive, pouring the HSDF adhesive, observing an injection process, shifting, cleaning the injection equipment, checking the pouring effect and recovering a steel liner, and finishing the construction. The construction method has thecharacteristics of little pore opening for the water turbine volute structure, low construction pressure, safe and reliable construction, short construction period, high construction efficiency, safety, ...

The invention relates to a device and a method for testing inside relative humidity of a cement base material (such as cement mortar, concrete and the like) during hydration. The inside relative humidity testing device consists of a temperature humidity sensor, a sleeve, a filter membrane, sealant and a conducting wire, wherein the temperature humidity sensor is connected with the conducting wireand then sleeved into the sleeve, the temperature humidity sensor is flushed with the top end of the sleeve, the sealant is poured into the bottom of a sensing chip of the temperature humidity sensorfrom the bottom end of the sleeve, and the waterproof ventilated hydrophobic filter membrane is covered at the top end of the sleeve and adhered to the side of the sleeve by the sealant. The testing method comprises the following steps: embedding the device in the middle part of the cement base material, introducing the conducting wire to the outside of a tested object, then pouring the concrete,connecting ...

The invention discloses a three-dimensional microscopic simulation model of concrete and an establishment method thereof, belonging to the technical field of microscopic numerical value test pretreatment. The three-dimensional microscopic simulation model of concrete comprises an aggregate unit generated with a background grid method, a mortar unit and a zero-thickness interface unit, wherein the zero-thickness interface unit is the interface unit of the aggregate unit and the mortar unit. The model establishment method comprises the following steps: identifying the aggregate unit and the mortar unit with the background grid method; and simulating the interfaces of the aggregate unit and the mortar unit into the zero-thickness interface unit. On the basis of the traditional background grid method, the concept of the zero-thickness interface unit is introduced with the model establishment method to simulate an aggregate-mortar interface, and the background grid method is improved and is ...

The invention discloses hydraulic structure disjoint filling silicone adhesive, which is prepared from a component A and a component B according to a weight proportion, wherein the component A comprises 100 portions of alpha, omega-dihydroxydimethylpolysiloxane and 15 to 45 portions of calcium carbonate filler; and the component B comprises 3 to 10 portions of calcium carbonate filler, 6 to 15 portions of methyl vinyl disilane, and 3 to 10 portions of linear amino polysiloxane cross linker. After stirring and mixing according to the weight proportion, the components are separately sealed and stored; and during use, the component A and the component B are mixed according to the weight proportion and vulcanized at room temperature to form the hydraulic structure disjoint filling silicone adhesive. The hydraulic structure disjoint filling silicone adhesive has the characteristics of room temperature vulcanization, double components, self leveling, adjustable curing speed, low modulus, high ...
