Description

Multifunctional sediment inspection well

Technical Field

The utility model relates to the technical field of municipal drainage, in particular to a multifunctional silt inspection well.

Background

The sludge settling inspection well, namely the sludge settling well, is usually arranged in a municipal domestic sewage drainage pipe network, and is used for depositing and collecting the soil in a drainage pipeline by using a sludge settling tank, and the sludge is intensively cleaned after being fully collected, so that the content of the sludge in a sewer pipeline can be reduced. In addition, when the sewer pipe is used for cleaning and digging, the function of storing mud is also achieved. The side wall of traditional mud trap sets up oral siphon and outlet pipe respectively, and the bottom of the well portion is the mud groove, and the oral siphon lets in sewage, and the mud in the sewage is because the action of gravity deposit is in mud groove bottom portion, and the clear water on upper strata passes through the outlet pipe and discharges. The traditional sediment inspection well has the following defects: 1. the sediment inspection well needs to be inspected and maintained regularly, and as a large amount of toxic and harmful gas is generated at the bottom of the well by dirt, maintenance personnel can enter the well body to determine whether the concentration of the toxic gas in the well meets the standard or not, so that the sediment inspection well can be operated in the well, the maintenance personnel often carry a handheld mobile gas detector to operate in the well, and the handheld equipment is heavy and large in size and is not beneficial to the action of the maintenance personnel; 2. traditional oral siphon and outlet pipe do not establish the gate valve, and when maintainer was in the borehole operation, the oral siphon also intake simultaneously, and the mud groove can't be drained, has hindered maintainer's action greatly.

Disclosure of Invention

The utility model aims to provide a multifunctional silt inspection well, which can realize the function of maintaining a well body by maintenance personnel in a dry and safe environment, is convenient and fast to operate and is beneficial to popularization and use in a municipal sewage system.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

a multifunctional mud sinking inspection well is characterized in that a water inlet pipe and a water outlet pipe are respectively arranged on two sides in a well body, a water inlet flashboard is arranged at the pipe opening of the water inlet pipe, and a water outlet flashboard is arranged at the pipe opening of the water outlet pipe. When maintenance personnel enter the well body, the carried water inlet flashboard is inserted, the flow of water at the water inlet is controlled, and then sewage in the well can be pumped out, so that the maintenance personnel can perform maintenance work in a relatively dry and good environment; meanwhile, the water outlet flashboard can be inserted to prevent the sewage in the water outlet pipe from flowing backwards, or the harmful gas in the water outlet pipe can be controlled to enter the well body.

The end of the flow groove at the bottom of the well body is provided with a mud settling barrel, the edge of the opening of the mud settling barrel is lower than the flow groove, one end of the chain is fixed on the mud settling barrel, and the other end of the chain is fixed on the wall of the well close to the well opening. The sewage of outlet pipe flows into the interior collection back of stainless steel mud sedimentation bucket through the chute of slope, and the maintainer that is located the well draws stainless steel chain through carrying, will sink the mud bucket and draw to the aboveground processing, transfers the underground again and lays, and then realizes the dry clean environment in shaft bottom.

And a gas detector is arranged on the inner wall of the well body. The gas detector is fixed in a line type gas detector, the detector is directly and fixedly arranged in the well, and a gas sensor is arranged in the detector and can be used for detecting harmful gases such as CO and CO₂、Cl₂Methane, ethane and H₂S, and the like, wherein a liquid crystal display screen is arranged on the detector and can display the concentration value of the harmful gas in real time, a maintainer can directly observe the value of the detector to judge whether the concentration value meets the maintenance working environment, and if the concentration of the toxic and harmful gas exceeds the specification in table 5.3.5 in the technical regulations on urban drainage pipeline maintenance (CJJ 6-2009), the ventilation device is adopted for ventilation treatment, and the concentration of the harmful gas is reduced to be below the standard value and then enters the detector. The power line of the gas detector is connected into a municipal underground cable near the mud pit through an adaptive voltage transformation device to provide power.

The water inlet pipe orifice and the water outlet pipe orifice are respectively embedded with angle steel, the position of the angle steel corresponds to the side edge positioning positions of the water inlet flashboard and the water outlet flashboard, and the concrete at the bottom edge of the water inlet flashboard and the water outlet flashboard is provided with a matched groove. Through the limitation of the angle steels on the two sides and the limitation of the groove at the bottom, the flashboard can be firmly fixed at the pipe orifice, and the situation of displacement or rushing out cannot occur.

The utility model has the advantages that:

(1) the utility model can realize the function of maintaining the well body and the pipe network by maintainers in a relatively dry and safe environment, and when the device is used daily, the flashboard is opened, and dirt is deposited in the mud settling barrel by gravity. The staff accessible is put down the flashboard, controls the inflow to accessible steel hinge pulls out the well with stainless steel mud bucket that sinks, treats that the stainless steel mud bucket that sinks clears away clean back, places in the pit again, if there is the disease in inspection shaft upstream and downstream pipeline, still accessible flashboard control rivers get into, the going on of the pipeline repair work of being convenient for.

(2) The gas detector is arranged and installed, so that the gas condition in the well can be judged through the harmful gas detector during maintenance, and personnel can be arranged to go into the well when the concentration of the harmful gas in the well is reduced to be within a safety value by the temporary ventilation device, so that the safety maintenance work is realized.
