The concrete drainage pipe is currently the domestic medium and large caliber reinforced concrete drainage pipe production process which mainly includes four processes: centrifugal, suspension roller, vertical vibrator, and core mold vibration. Based on the analysis of the application of these four processes in production practice and the characteristics of the process, we found that the mandrel vibration process produces reinforced concrete drainage pipes that are superior to other products in terms of product quality, production efficiency, labor intensity, energy saving, and environmental protection. Process. Next Xiaobian introduced the features of concrete drainage pipe installation and concrete drainage pipe. Concrete drainage pipe installation 1, the preparation of the pipeline before laying 1) Prepare construction equipment, tools, lifting equipment, socket tubes, rubber rings, and lubricants. 2) Review the groove center line and the base elevation. 3) Remove grease and debris from the inner surface of the socket and the outer surface of the socket. 4) Select the appropriate rubber ring according to the pipe diameter, and check that the appearance of the rubber ring should be free from defects such as air bubbles, cracks and bumps. 2, security management order 1) From upstream to downstream, the inlet is downstream and the inlet is upstream. 2) In order to accurately control the pipe position, the two ends of the first pipe must be supported and fixed at the two ends. 3) It is used as a method for adjusting the position of the center line of the tube end of the next section and the method for fixing the adjusted tube head. 3, pipe section closed by two lever hoist method One end of the lever hoist is connected with the cable hook of the socket and the other end is used as the fixed reaction force end. When the pipe joints are closed, the two lever hoists should be placed at the horizontal diameter of the pipe joint. The hook is hooked on the socket wall of the closed pipe joint. The lever of the lever hoist can be fixed to the temporary timber by wire ropes, snaps, etc. When closing, the two lever hoists should be pulled synchronously so that the pipe joints can be closed. 4, pipe socket in place, relax the wire rope should perform the following checks Review the tube elevation (elevation) and centerline. When the height is in error, use the crane to adjust; when the pipeline is over high, use a spatula to remove the sand layer, and when the pipeline is low, stuff the sand and use a small rake to hit it. Check the clearance between sockets is 9mm~15mm. After being in place, two sets of 4 wedge-shaped concrete blocks can be wedged tightly at the bottom corners of both sides of the pipeline at a support angle of 90°. The longitudinal position of each group is 1/5 from the end of the pipe. Concrete drainage pipe features 1. Drainage safety The hole is located in the trough. Due to the two-way effect of the wave crest and the filter fabric, the hole is not easy to be blocked and the permeation system is unblocked. 2, corrosion resistance Plastics are less likely to rust than soft Spring drains. 3, strength and easy to bend The unique double corrugated structure effectively increases the external pressure strength of the product, and the drainage system is not affected by external pressure deformation and affects the drainage effect. 4, economic type Compared with other drains of the same caliber, the price is lower. Editor's summary: The characteristics of the installation of concrete drainage pipes and concrete drainage pipes are introduced here. I hope to help everyone.
