Description

Sewer wellhead structure for easy sludge removal

technical field

The utility model belongs to the technical field of municipal construction, in particular to a sewer wellhead structure which is convenient for cleaning mud.

Background technique

The construction of the sewer will be equipped with a wellhead connected to the ground to facilitate the drainage of rainwater. During long-term use, a lot of silt will accumulate in the sewer, and if it is serious, it will block the sewer, so the sewer needs to be cleaned regularly. The sewer structure brings a lot of inconvenience to the cleaning work, because the silt is scattered in the sewer, and there is a problem of unclean cleaning. Even if there is a silt pool, the cleaning efficiency is very low, and in most cases, workers need to go down to the Down the well.

Contents of the invention

The purpose of the utility model is to provide a sewer wellhead structure which is convenient for cleaning mud and has high efficiency.

The purpose of this utility model is achieved in the following way: the sewer wellhead structure for easy cleaning of silt includes a wellbore and a well chamber, and a sewage outlet is arranged on the side wall of the bottom of the wellbore, wherein a sludge pond is arranged in the chamber of the well, and a mud pond is arranged on the mud pond. A filter screen is laid, and the silt can settle on the filter screen. The two sides of the filter screen are provided with drawbars, and the drawbar extends along the inner wall of the wellbore to the wellhead. Rollers are arranged on the drawbar, and the wellbore The inner wall of the tank is provided with a grooved slideway, the rollers are located in the grooved slideway, and the draw bar can slide upward along the grooved slideway, and drive the filter screen in the sludge pool to rise.

According to the above-mentioned sewer wellhead structure which is convenient for cleaning mud, wherein, the end of the draw rod is provided with a connecting ring, which is convenient for fixing the draw rod and lifting the draw rod and the filter screen upward.

According to the above-mentioned sewer wellhead structure for easy sludge cleaning, a reinforcing plate is arranged under the well chamber to increase the area of the bottom of the well chamber and prevent sinking.

Compared with the prior art, the utility model has outstanding and beneficial technical effects: the sewage circulates in the sewer, and when passing through the well chamber, the low-level effect of the sludge pool can be used to precipitate the sludge, and the sludge is concentrated on the filter net. When cleaning, only It is necessary to use the tow bar to lift the filter screen out of the well chamber to complete the cleaning of the sludge. The operation is simple and convenient, and the efficiency is high.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described with specific embodiments, referring to Fig. 1-2: the sewer wellhead structure that is convenient for cleaning silt, comprises well shaft 10 and well chamber 11, and the side wall of well shaft 10 bottom is provided with blowdown outlet 12, A well cover mounting seat 13 is arranged on the end face of the well shaft 10, and a well cover 14 is placed on the well cover mounting seat 13, wherein a sludge pool 12 is arranged in the well chamber 11, and a filter screen 16 is laid on the sludge pool 12, and the sludge can be Precipitated on the filter screen 16, the two sides of the filter screen 16 are provided with a draw bar 17, the draw bar 17 extends along the inner wall of the shaft 10 to the wellhead, the draw bar 17 is provided with a roller 18, the The inner wall of the shaft 10 is provided with a grooved slideway 19, the roller 18 is located in the grooved slideway 19, the drawbar 17 can slide upwards along the grooved slideway 19, and drives the filter screen 16 in the sludge pool 12 rise.

Further optimization, the end of the draw bar 17 is provided with a connecting ring 20, which facilitates fixing the draw bar 17 and lifting the draw bar 17 and the filter screen 16 upward.

For further optimization, a reinforcement plate 21 is provided below the well chamber 11 to increase the area of the bottom of the well chamber 11 and prevent sinking.

When it is necessary to clean up the mud, the well cover 15 is opened, and the connecting ring 20 on the traction bar 17 is connected with a traction device, and the traction device is started. With the assistance of the roller 18, the traction bar 17 slides upwards with the filter screen 16, and the filter screen 16 is completely After breaking away from the well shaft 10, the silt on the filter screen 16 is cleaned up, and finally the drawbar 17 and the filter screen 16 are put back into the well shaft 10 and the well chamber 11 along the groove slideway 19, and continue to collect the silt, which is convenient for cleaning next time.
