Which is the best cement pipe in Huai'an
2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.

The common problem of cement pipe is erosion. The erosion problem of cement pipe mainly includes crevice corrosion and corrosion. These two erosion methods belong to diffuse erosion and are not easy to be detected by inspectors. The other kind of intergranular corrosion cracking is the pipeline cracking caused by erosion and other external effects of support force and ground stress, causing huge damage. At this time, the pipeline shall be removed and replaced in time. There is also a common problem of mechanical equipment damage. This kind of damage mainly includes chisels and pits containing chisels, which is generally caused by mechanical equipment damage. External cracks are also a problem of cement pipes. These problems belong to the plan problem and can be easily detected. Peeling is a relatively serious damage condition, and perforation will lead to fracture or leakage.

Cement pipes can be used in many fields, such as rainwater drainage, sewage drainage, industrial wastewater drainage and community drainage. As well as the buried pipelines of highways, or for protecting cables, optical cables, etc. Cement pipes have the following characteristics: 1. Generally speaking, they have rigidity, flexibility and excellent mechanical properties. And it has strong compressive properties. 2. The chemical property is stable, generally corrosion resistant, but non-toxic, and it is an excellent environmental protection pipe. 3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years.

How is Jiaxing cement pipe made? First of all, the items needed for the production of cement pipes: steel bars, fine aggregate concrete, seam slots, steam chambers, reinforced shelves, cement pipe molds. Manufacturing process of cement pipe: first bind the reinforcement of cement pipe on a shelf, then wrap the reinforcement cage with a special mold, then pour fine aggregate concrete from a slot, seal the slot, then turn on the motor, make the rotary shaft in the cement pipe run to drive the cement pipe to rotate, make the concrete gradually dense through centrifugal operation, and then put it into the steam chamber for curing, Take it out when the strength of formwork removal is reached.

Maintenance means no steam curing tank. After the cement pipe is made on the cement pipe making machine, it is not necessary to open the grinding tool. Put the cement pipe mold and cement pipe outdoors for regular maintenance. Generally, after the cement pipe is made, it takes one day to carry out outdoor maintenance. The grinding tool can be opened the next day. After the mold is made, it also needs to carry out 4-6 days of regular maintenance, and full-time personnel should spray water on the cement pipe three times a day, The time of sprinkling is usually once in the morning, once in the afternoon and once at noon. The purpose of sprinkling is to maintain the environmental humidity of the cement pipe so that the concrete can gradually coagulate itself. The frequency of sprinkling can also be increased and reduced according to the environmental humidity of seasonal changes in weather conditions. But of course, there are more cement pipe molds required for maintenance.

Bored cast-in-place pile has strong vitality because of its high bearing capacity and adaptability to complex geology. However, this pile type needs to deal with the mud pumped out during construction, which causes serious environmental pollution. It has been less used in urban construction at home and abroad, and its production cost is quite high, so it is relatively less used in general industrial and civil buildings. The advantages and disadvantages of precast concrete square piles have been described, which will not be repeated, but it is worth mentioning that its construction damage rate is very low, which is also one of the starting points for our development and production of prestressed hollow square piles; At the same time, because it is solid and has a large dead weight, cracks often appear on the pile body during construction, resulting in poor durability of the pile
