Haichen Supply Bridge Water Collection Well/Box Bridge Water Collection Box Support Customization

Description :

　　Collecting well dewatering, also known as foundation pit drainage, refers to setting up a collecting well at the bottom of the foundation pit during excavation, and excavating drainage ditches around or in the center of the foundation pit bottom to allow water to flow into the collecting well. Artificial precipitation measures must be taken, and then a construction method that uses water pumps to extract water is characterized by simple equipment, convenient management and maintenance, and is mainly suitable for situations with good soil conditions and low groundwater. The collection well plays a role in collecting water. It is a well connected to a drainage ditch, and the supply price of the bridge collection well is usually pumped to the municipal drainage pipe by a water pump. Taking the basement water collection well 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. Deep precipitation wells can even reach 50-60 meters. Precipitation wells are classified into light, medium, and other types. According to different principles, it can be divided into many types. Sealed well, connected together, pumped, bridge collection well construction, using submersible pump for deep well pumping.

　　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.
