The practice of sewage well sewage pipes, how to connect the sewage pipes out of the house to sewage

Generally speaking, there are many ways to make holes in the wellbore and install saddle joints. If the elevation of the outlet pipe is too low, you can also use the confluence plate.

A bilge well is a small container for the temporary placement of ship sewage and is also an integral part of the ship's bilge water system. The bilge water system is a pipeline system that discharges the bilge water in the cargo hold and furnace compartment of the ship or the stagnant water and seepage water in the double bottom outboard. The sewage well plays the role of temporarily collecting bilge water such as oily sewage generated in the engine room.

In the normal operation of the ship, due to the leakage of engine room equipment, the leakage of various pipelines, flushing water, the leakage of the hull joints that are not tight, the rainwater flowing from the hatch and the hydrophobic discharge of the deck or cabin near the waterline, etc., all gather in the bilge to form bilge water.

Bilge water has a corrosive effect on the hull; Water accumulation in the cargo hold will soak the cargo and cause damage to the cargo; Water accumulation in the bilge of the engine room will cause damage to the mechanical and electrical equipment by moisture or immersion in water, affect the normal operation of the machine, and bring difficulties to the management work. When there is too much bilge water, it will seriously affect the stability of the ship and endanger the safety of navigation.

The function of the bilge water system is to drain the bilge water from the furnace compartment and cargo hold to the outboard in time. Ships in normal operation have less water accumulation in the engine room bilge. The bilge water system can also be used to drain stagnant water in the event of a ship breakdown.

The stagnant water in the cargo hold generally does not contain oil and is usually discharged directly to the outboard; The water in the engine room generally contains oil, so it needs to be treated by an oil-water separator, and when the oil content is less than 15 mg L, it can enter the sea in the specified sea area.

The bilge water system is generally composed of a bilge water pump, a bilge water pipe, a bilge water suction port, valves and related accessories. A small amount of stagnant water can be collected and treated in cargo holds, engine rooms, gyms, sounder cabins and other places.

Dear, hello, I am happy to serve you, the answer is as follows Use the wall to drill holes with elbows to lead out of the wall to introduce sewage wells Generally speaking, there are many ways to open holes in the wellbore, and install saddle joints. If the elevation of the outlet pipe is too low, it can also be used to set the point with the confluence plate 1 and the pay-off, which is the foundation work before the construction of all working pits and receiving pits; 2. The pipeline is in place, and the excavation of the working pit and the receiving slip pit in the general pipe jacking construction are very critical processes; 3. The direction of the connecting pipeline of the working pit, pipeline and receiving pit must be controlled in the process of jacking the working pit, and the deviation should not be too large; 4. Determine the size of the excavation, and determine the diameter of the riding well according to the pipe mountain of the drainage pipeline. 5. Manual excavation, binding steel bars, supporting formwork, and pouring concrete can be done.

Hello, 1.First, the corrugated pipe culvert is measured and set out, and the position of the pipe culvert is determined to ensure that it is connected with the previous water system in place. Sweet potato 2

The excavation belt is excavated with a Sakura-digger excavator, and the excavation slag is loaded into a dump truck and transported to the slag dump. 3.After the foundation excavation is completed, the bearing capacity of the foundation is tested, and the penetration detector can be used for testing.

4.After the test is completed, the design requirements are met, and the concrete cushion is poured on site, and the pouring thickness is not less than the design value.

There are usually three ways to connect a sewage pipe to a well. The first way is to use rubber gasket connection, which can ensure the drainage capacity of the pipeline and the sealing of the well. The second way is to use rubber joints to connect, this connection method is to glue the two pipes together through rubber joints, which can effectively prevent water leakage.

The third way is to use a welded connection, which requires heating on the pipe and welding the two pipes together, and the welding quality can only be ensured when the pipe fit is high.

In order to ensure the quality and stability of the sewage pipe and the well connection, the following aspects need to be paid attention to. First of all, it is necessary to choose the appropriate interface connection method, and choose different connection methods according to different engineering needs, for example, rubber gasket is suitable for light sludge drainage system, and welding is suitable for large industrial drainage system. Secondly, it is necessary to ensure that the diameter of the pipeline and the size of the well match to ensure the stability and tightness of the connection.

In addition, it is necessary to pay attention to the clean and leveling of the construction site during construction, and strictly follow the construction specifications and standards to ensure the quality of the connection.

In addition to the above-mentioned connection methods, there are also some new connection methods that can be used to connect sewage pipes to wells. For example, polyethylene bellows and biomimetic bone connection technology. Polyethylene corrugated pipe has good corrosion resistance and elasticity, and is suitable for some marine or chemical industry sewage treatment systems.

Bionic bone connection technology is a kind of bioengineering technology, which can ensure the high strength, high tightness and high reliability of pipe connection through the principle of biomimicry, and can be used in some drainage systems that require high standards.

In short, there are many ways to connect sewage pipes and wells, and it is necessary to choose the appropriate connection method according to the actual situation, strictly abide by the regulations and standards in the construction process, ensure the quality and stability of the connection, and improve the efficiency and safety of the sewage treatment system. <>

Hello dear, it is a pleasure to serve you, about your question: "How to install the management well of the rain and sewage pipe" has been found: The management well of the rain sewage dust burial pipe is installed as follows:

1. The connection between the well seat, the wellbore and the pipeline, the connection between the well seat and the pipeline, the inspection well seat and the pipeline connection and installation sequence, should be installed from the upstream section of the household pipe, installed in the order of the well pipe and well pipe, and extended to the downstream branch pipe and main pipe. The construction method of the connection between the well seat joint and the pipeline should be consistent with the construction method of the pipeline connection of the same type of joint. When the reducer joint is used, when the diameter of the incoming pipe is less than the diameter of the well seat interface, the top of the pipe should be connected flat; When the interface of the discharge pipe of the well seat is larger than the downstream pipeline, the inner bottom of the pipe should be flattened.

When the slope of the pipeline is adjusted by variable angle joints or ball joints, when the pipe diameter is greater than 315, special tools should be used and chain wrenches should not be used. The installation of additional joints should be based on the size of the wellbore and the diameter of the liquid cluster connecting the pipeline, and a special tool should be used to open a hole in the wall of the well, and the circumferential edge of the hole should be flat, and the installation of additional joints should not be reversed. During the construction period of high groundwater level or rainy season, when the installation of pipelines (including inspection wells) is completed (no irrigation test is carried out), technical measures should be taken to prevent the well from floating.

Second, the length of the wellbore installation wellbore should be the height from the bottom of the bearing mouth of the wellbore connected to the wellbore to the design ground, and then subtract the net distance from the wellbore to the ground. When the ground or pavement elevation is difficult to determine accurately, the wellbore length can be appropriately reserved for margin. The wellbore insertion into the well seat should be kept vertical.

When the wellbore is plugged in, it should not be beaten with a heavy hammer, and a special tightening tool should be used.

What kind of sewage wells are you going to make.
