Haichen Supply Bridge Cast Iron Water Collection Tank Municipal Project Special Bridge Deck Water Collection Box Casting Water Collection Well Multiple Specifications

Description :

　　The water collection tank plays a role in collecting water. It is a box connected to a drainage ditch, with a bridge water collection tank supply price, usually pumped to the municipal drainage pipe. Taking the basement water collection tank as an example, it is generally 1.5 × 1.5 × 1.5 meters. The precipitation well plays a role in precipitation. There are deep and shallow, and the depth is according to the precipitation requirements. The depth of the water tank can even reach fifty to sixty meters. There are light, medium, and other types of precipitation tanks. According to different principles, it can be divided into many types. Sealed well, connected together, pumped, bridge water collection tank construction, using submersible pump for deep well pumping. The manhole has been connected to the municipal government. Not suitable for making a collection well. The water collection tank also has a sedimentation effect. Generally, the water from the collection tank needs to be pumped to the sedimentation tank. Water collection tank, sometimes also known as inspection box, bridge water collection tank quotation, is a square box built with blocks at regular intervals or at turns when burying underground pipelines. Easy for regular pipeline inspection and dredging.

　　The bridge collection well plays a drainage role. In order to quickly clean up the water on the bridge surface and prevent rainwater from accumulating on the bridge deck and entering the beam, which may affect the durability of the bridge, in the design of the bridge, in addition to setting up longitudinal and transverse slope drainage, a certain number of drainage pipes need to be set up on the bridge deck to form a complete drainage system. The types of drainage pipes generally include metal drainage pipes, reinforced concrete drainage pipes, horizontal drainage pipes, and closed drainage systems.

　　The manhole has been connected to the municipal government. Whether temporary fixed facilities have been removed, whether PTFE skateboard supports have been injected with silicone grease oil (lubricating oil is strictly prohibited from replacing silicone grease oil), and other phenomena, once discovered, should be adjusted and dealt with in a timely manner to ensure the normal operation of the supports after installation, and all deviations and abnormal situations that occur after the installation of the supports should be recorded. The average compressive stress during the use stage of the 3.5 support is σ c=10MPa. The volume of the rubber elastic body of the support is Eb=2000MPa. When the support comes into contact with concrete, the friction coefficient μ=0.3; When in contact with steel plates, the friction coefficient μ=0.2; The friction coefficient between polytetrafluoroethylene plate and stainless steel plate (with silicone grease added) is 0.06 μ f. When the temperature is below -25 ℃, the μ f value increases by 30%. When silicone grease is not added, the μ f value should be doubled. 3.6 When installing rectangular supports, place them along the bridge direction with the short side dimension. As a manufacturer of rubber bearings, there are generally two standards for commonly used plate rubber bearings and PTFE plate rubber bearings.

　　It's about enterprise standards and national standards. The pot type rubber bearings for railway bridges can be divided into three types: ZX, HX, DX, and GD. The stainless steel plates in the pot type rubber bearings are flat stainless steel plates and lateral stainless steel plates, and the materials are generally used. The main function is to form a sliding pair with the flat PTFE plate and the side sliding plate. By utilizing the low friction coefficient between the two, the friction resistance during bridge sliding can be reduced, thus meeting the requirements of railway bridge sliding. To minimize friction as much as possible, stainless steel plates should be cold-rolled mirror stainless steel plates. According to the relevant regulations of T3280, the surface of the steel plate should meet the processing requirements of 8 surfaces. When the length of the stainless steel plate is not greater than 1500mm, the plate thickness is 2mm; when the length of the stainless steel plate is greater than 1500mm, the plate thickness is 3mm. The seismic isolation rubber bearing is composed of rubber and sandwich steel plates layered and bonded by high-temperature vulcanization. When the rubber bearing bears vertical loads, the lateral deformation of the rubber layer is constrained.
