Description

A kind of water channel is passed by one's way the production method of prefabricated component
Technical field
The present invention relates to a kind of hydraulic engineering field, and in particular to a kind of water channel is passed by one's way the production method of prefabricated component.
Background technology
Water channel is the main tool of the filling such as irrigation and water conservancy, traffic, municipal administration, sewage, rainy day draining row's engineering, and concrete The U-shaped gool mould of soil is one of main tool for producing gool.
With greatly developing for China's modern agriculture and water resource infrastructure, country and place are built to agricultural and water conservancy basis If scale of investment it is increasing.China is one to the relatively backward country of agricultural technology, vast in territory, water resource assignment ten Divide inequality, it is particularly very in short supply to west area, the water resource of drug in some provinces.At the same time, due to filling row's mode and material It is unreasonable, great lot of water resources is not utilized and protected well, is had become in China's agriculture project and water conservancy construction The poorly efficient serious problems utilized of water resource.Over more than 20 years, precast concrete gool（Referred to as U-shaped gool）It is special in China each province and city It is not popularization and application in western water resources regional agricultural water conservancy project in short supply, it is agriculture abundant with hydraulic department has obtained various regions Certainly, significant economic benefit and social benefit are achieved.
Also there is many through retrieving the pass by one's way Chinese patent literature of prefabricated component of relevant water channel, it is as follows：

Embodiment
With reference to embodiments of the invention, the present invention is described in more detail.
Embodiment 1:
Referring to shown in Fig. 1 to 7, a kind of water channel is passed by one's way the production method of prefabricated component, and described method comprises the following steps：
（1）Making and the mould needed for water channel prefabricated component same shape, mould is inverted and put, from bottom casting concrete；
（2）On die inside on even application mould oil or pad on plastic sheeting；
（3）The framework of steel reinforcement made is inserted in and poured in mould, and adjusts the protective layer of concrete, described framework of steel reinforcement Trough rim by inside and outside stressing conditions configuration principal rod, bottom land is by upper and lower stressing conditions configuration principal rod, by the reinforcing bar of configuration point Then solution is welded into unit member, several unit members is welded to connect with longitudinal reinforcement to be formed into the shape that can be processed The framework of steel reinforcement of gool, the both ends distribution unit component on framework of steel reinforcement is closeer, and intermediate distribution unit member is sparse and uniform；
（4）Field fabrication pours required concrete；Concrete is poured among mold bottom, uniformly divided to both ends, then Vibrated, vibrated 1~3 minute using direct insertion vibrator, discharged the bubble in concrete, combine concrete compaction, then to mould Have notch upper surface and carry out troweling；Closed die cover plate；
（5）Water channel prefabricated component after casting concrete conserves at the scene, removable side mould after temperature is more than 500h DEG C during maintenance, Removable internal model after temperature is more than 1500h DEG C during watering maintenance, tear prefabricated component after internal model open and concentrate stacking, Wen Da during maintenance Can dispatch from the factory use at more than 2000h DEG C.
Temperature is time × outdoor temperature when above-described, and the chronomere is hour, and time numerical value takes >=16 Positive integer, i.e. time add up and value >=16, time numerical value can use the numerical value such as 16,17,18,19,20,21,22,23,24, described Outdoor temperature unit for degree Celsius, outdoor temperature >=20 DEG C, outdoor temperature can change with seasonal variations, when outdoor temperature is less than At 20 DEG C, do not construct；And outdoor temperature is high, time numerical value is relative to get the small value, i.e., shortens the time required to maintenance.
After cast in situs terminates, so that it may pair when be included in curing time, it is 9 points of morning to pour end, i.e., since 9 points of morning Timing；Take that 9 points of morning, totally 12 hours, outdoor temperature were 30 DEG C to 21 points at night the period, when temperature for 12 × 30= 360h·℃；21 points to 9 points of morning next day at night, totally 12 hours, when temperature be 12 × 28=336h DEG C；Two periods Numerical value is added, and as 360+336=696h DEG C is more than 500h DEG C, can remove the die cap plate, side wall mould, end cap mould of mould.
Watering maintenance, from 10 points of morning to 21 points at night, outdoor temperature is 30 DEG C, when temperature be 11 × 30=330h DEG C； 21 points to 9 points of morning at night, and outdoor temperature is 28 DEG C, when temperature be 12 × 28=336h DEG C；9 points to 21 points of morning, outdoor temp Spend for 32 DEG C, when temperature be 12 × 32=384h DEG C；21 points to 9 points of morning at night, and outdoor temperature is 30 DEG C, when temperature be 12 ×30=360h·℃；9 points to 14 points of morning, outdoor temperature be 31 DEG C, when temperature be 5 × 31=155h DEG C；By the stage Numerical value adds up, and as 330+336+384+360+155=1565 are more than 1500h DEG C, you can removes die cavity, prefabricated component is hung Die cavity, carry out stacking maintenance.
