In recent years, along with the acceleration of urbanization in China, many cities have continuously increased investment in infrastructure, underground pipe network construction has received unprecedented attention and development, and the dredging and maintenance of urban drainage pipe network has also been greatly improved. However, due to constraints of urban construction, economic conditions, and management methods, it is often overlooked that the maintenance, management or maintenance management of the completed drainage pipe network is not sufficient, no necessary inspection methods are adopted, no scientific and systematic management mechanisms are formed, and urban drainage Because of the long-term collection of sewage and ground rainwater, the pipeline network will have more and more accumulated garbage. If you do not pay attention to the dredging and dredging work of the sewers for a long time, it is very easy to cause blockage of the urban drainage pipelines and cause flooding. The solution to blockage of urban sewage pipelines has become the top priority for the modernization of urban construction. The smooth flow of drainage is to protect the environment from pollution, to protect the city from floods and to ensure the health and normal life of the general public. However, due to the rapid development of urban construction, construction and maintenance of some pipelines have lagged behind urban development, resulting in partial blockage of the pipeline or poor drainage, which directly endangers the quality of urban public services and urban security.
In order to facilitate the sewer dredge and management, there will be an inspection well every 20 meters on the road, which facilitates the dredging of the management department, but also provides the conditions for the silt accumulation of the sewer. When the road scorises or rains, the rain will see the mud and sand on the road seepage through the inspection wells into the sewers, causing mud deposits in the sewers and affecting urban drainage. There are also restaurants and hotels that discharge organic waste water. Suspended matter and grease are another important source of silt accumulation in sewers. The main components of the dredge car are hydraulic systems. The high-pressure cleaning truck is mainly used for the sedimentation of the pipelines and the dredging of dead mud. It can also be used for cleaning industrial drainage pipelines, walls, etc., and cleaning roads and squares. High-pressure cleaning vehicles can also be equipped with sprinkler devices, green sprinkler guns, front punches, rear sprinklers, and side sprays. They can be used for greening, spraying, dusting, and high-pressure flushing of road surfaces. They can be used for fire fighting in case of emergency.
Before cleaning, the body surface temperature should be cooled below 60°C, and the ambient temperature should be maintained at 0-40°C. The water gun is more than 15 cm away from the body paint surface. The order of flushing is from the roof to both sides. When rinsing the grille part in front of the car, misty water flow should be used, and the water column should not be flushed against the fins of the water tank or condenser. If the plastic arch cover is installed at the mudguard, it should be removed and cleaned, and the mudguard should be thoroughly cleaned. , Fender inside. 1. It is to clear away the remains of the car body. You can use the all-round descaling water to wipe with a clean cotton cloth. Then wring out the dustless cotton cloth with the car wash liquid, dry the car paint along the direction perpendicular to the car's driving direction. Car wash on the surface. Finally, rinse the car wash thoroughly with plenty of clean water, and dry it with a synthetic sheepskin towel. Wipe dry to achieve the whole car water-free traces, glass without stains 2. High-pressure water gun cleaning, is the use of high-pressure water gun from top to bottom will be contaminated in the body surface of the sand washed away, then rinse the back of the car body, and finally wash the lower part. This step is to pay attention to the need to fully flush the chassis and thoroughly clean the edges, bends, fenders, etc. Particular care should be taken to thoroughly clean the sand and dirt from the wheels, brake discs, fenders, front grilles, door frames, and skirts. 3 is to wipe, use a car wash sponge shampoo car shampoo, wipe the body again, if contaminated objects are not easy to remove, you can repeatedly wipe, pay attention to wipe the body up and down the sponge to be used separately, so as not to scratch the body under the sand paint body paint. Then rinse with high-pressure water, in particular, to clean the seams at the car seams, foam at the corners, etc. 4. Apply liquid to spill the shampoo car wash on the body. There are two methods, one is to use multi-functional high-pressure foam washing machine, spray evenly, to the upper and lower regularly shaking nozzle; the second is manual preparation, that is, according to a certain proportion of shampoo car wash liquid, do not use washing powder, soapy water, Dewaxing detergent.
Laser Distance Measure is a very convenient tool for various types of applications in industries, construction and house decoration. Laser Distance Meter is a very useful device which gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, infrastructures, gardens, roads, and many other applications requiring accurate results for distance , area and volume measurement.
Trade your heavy tape measure for laser
rangefinder, which let you simply take measurements with one hand. No matter
your job, the Laser Rangefinder will help you measure much farther, with
greater accuracy and in more situations, saving you money and time.
