Description
Technical Field
The invention relates to a setting method of a rain and sewage drainage inspection well applied to a comprehensive pipe gallery, in particular to a setting method of an inspection well used under a city comprehensive pipe gallery Fang Yu and a sewage pipe (canal) without affecting the arrangement of square pipelines on the comprehensive pipe gallery.
Background
Urban engineering lines such as rainwater can be incorporated into the utility tunnel, and sewage pipe inlet tunnels are preferably arranged below other lines, as clear from the technical specifications of urban utility tunnel engineering (GB 50838). However, rain and sewage water entering galleries face some difficulties when arranged below the pipe gallery: the rain and sewage pipes (channels) need to be provided with inspection wells at certain intervals for accessing rain water or sewage and cleaning and overhauling. For ease of access, manholes typically require access directly to the surface. When the pipelines are also arranged above the rain water pipe and the sewage pipe (canal), the inspection shaft needs to be avoided. If the upper pipeline does not have a clear condition (e.g., gravity line), it can present difficulties in setting up the manhole for the lower Fang Yu, sewer (or canal) lines.
Therefore, a drainage manhole process applied to the comprehensive pipe gallery is provided, and the above difficulties existing when rain and sewage enter the gallery to be arranged below the pipe gallery are solved by adjusting the horizontal arrangement position of the manhole.
Disclosure of Invention

In order to achieve the above purpose, the technical scheme of the invention is as follows: the method for setting the rain and sewage inspection well applied to the comprehensive pipe gallery is characterized by comprising the following steps of: an inspection well which is communicated with the ground is arranged at intervals along the comprehensive pipe rack, the inspection well is arranged at one side of the comprehensive pipe rack, and an inlet and an outlet of the inspection well are directly communicated with the ground upwards; the rain and sewage channels in the utility tunnel are connected with the flow channel at the bottom of the inspection well through the inclined flow guide channels.
According to a preferred embodiment of the invention, the rain and sewage channel is a rain water channel or a sewage channel.
According to a preferred embodiment of the invention, the rain and sewage channels are in the form of pipes or channels.
According to a preferred embodiment of the invention, the angle between the diversion channel and the rain and sewage pipes is a, and a is preferably not more than 45 degrees.
According to the preferred embodiment of the invention, the flow passage area of the diversion channel is close to or larger than that of the rain and sewage pipes.
According to the preferred embodiment of the invention, the bottom of the diversion channel is provided with a launder, and the bottom of the flow passage of the inspection well is also provided with a launder.
According to the preferred embodiment of the invention, a liquid level detection facility is arranged in the inspection well and is used for monitoring whether the liquid level of the rain and sewage system is in a normal range or not, and when the abnormal water level is detected, an alarm signal is sent to a pipe gallery monitoring system or a rain and sewage system operator.
The traditional inspection well is positioned in the same straight line with the rain water pipe and the sewage pipe (canal), the inspection well moves horizontally along the radial direction of the rain water pipe and the sewage pipe (canal), avoids the rain water pipe and the sewage pipe (canal) and the upper pipe line thereof in the horizontal position, and the inlet and the outlet of the inspection well are directly upwards led to the ground. The horizontal distance between the inspection well and the rain and sewage pipes (channels) is staggered, and the inspection well is connected by rotation through a diversion channel with an included angle a with the rain and sewage pipes (channels). In order to ensure the water passing capacity and the water passing effect, the water guiding channel has water passing area near or greater than that of rain water pipe and sewage pipe, and semi-circular or other flow grooves may be set in the bottom of the water guiding channel.
The rain and sewage inspection well technology applied to the comprehensive pipe rack has the following advantages:
1. when rain and sewage pipes (channels) enter the corridor and are positioned below the pipe corridor, the inspection well cannot influence the arrangement of pipelines above, and the arrangement of the pipelines above is concise and smooth.
2. When rain and sewage pipes (channels) enter the corridor, the inspection well cannot influence the arrangement of the upper pipelines, so that the upper pipelines on the same side can be gravity channels.
3. The inlet and outlet of the inspection well are vertically communicated with the water flow passage up and down, so that the inspection well is convenient to overhaul and clear.
4. The proper included angle a can be used according to actual conditions by arranging the diversion channel, the launder can be arranged, the hydraulic conditions are good, and the blockage is not easy to occur.
5. By arranging the liquid level detection facility, intelligent monitoring can be carried out on the rain and sewage system, alarming is carried out under the conditions of blockage and abnormal rise of the water level, overhaul is prompted, management upgrading of the rain and sewage system is realized, and response speed under fault working conditions is accelerated.
