Background

The mud well of the water supply pipeline is an important auxiliary well in municipal water supply pipelines and long-distance water pipelines, and the well is generally arranged at the lower parts of water pipelines, water distribution pipe network low-lying parts and valve inter-pipe sections and is used for draining mud for pipelines and overhauling the pipelines.

The traditional mud well consists of a mud valve well and a mud wet well. The mud valve is arranged in the mud valve well, and the valve is kept in a normally closed state at ordinary times, and is opened when the pipeline needs to drain mud and the pipeline overhauls and drains water, so that water is drained into the mud wet well. A high-level drain pipe is arranged in the mud-discharging wet well, and water released in the mud-discharging valve well automatically flows to a river channel or a nearby drain pipe network. The utility model patent of application publication number CN106320380A discloses a mud pit installation structure, and it includes the bottom plate, with the wall of a well of bottom plate fixed mounting and be located the apron of wall of a well top, bottom plate, wall of a well and apron enclose and establish to be a confined space, run through on the wall of a well and be equipped with the mud pipe, still run through on the wall of a well and be equipped with the overflow pipe, the height of overflow pipe is higher than the height of mud pipe. The mud well has a simple installation structure, and the sealing performance of the mud well can be enhanced by arranging the plastering inside and outside the well wall. This patent discloses the construction of a wet well for discharging mud.

In actual engineering, because the available area in urban areas is smaller, two wells are placed without space, or in field construction, because the valve wells need to occupy permanently, the occupied area of the two wells is larger, and the difficulty of land occupation examination and approval and implementation is larger.

The technical scheme adopted by the utility model is as follows: the utility model provides a water supply pipeline mud pit structure, includes mud pipe, mud pit, valve, outlet pipe, overflow pond, bleeder and manhole, and the mud pipe runs through mud pit lower part to communicate with outlet pipe one end, mud pipe, outlet pipe junction are provided with the valve, the upper portion of mud pit is provided with the overflow pond, the other end and the overflow pond bottom intercommunication of outlet pipe, the bleeder runs through the lateral wall of overflow pond, the top of mud pit is provided with the manhole.

Further, an overflow weir is arranged in the overflow pool, and the water outlet pipe and the water drain pipe are respectively positioned at two sides of the overflow weir.

Further, the overflow weir is a slope overflow weir.

Further, the overflow pool occupies part of the upper space of the mud well, part of the side wall of the overflow pool is shared with the mud well, and the drain pipe penetrates through the shared side wall.

Further, the number of the overhaul holes is two, one of the overhaul holes is opposite to the overflow pool, and the other overhaul hole is opposite to the bottom of the mud well.

Compared with the prior art, the utility model has the following beneficial effects: according to the utility model, the overflow pool is constructed in the mud well, the mud well is equivalent to a mud valve well, the overflow pool is equivalent to a mud wet well, the functions of the two well chambers of the existing mud valve well and the mud wet well which are independently arranged are realized in one well, the structural mode of the traditional mud well is simplified, the occupied area is reduced by about 50%, and the land resources are saved. The utility model has simple structure and is convenient for construction. The utility model fully considers the problem that the internal space of the overflow pool is smaller than that of the mud-discharging wet well, and designs the overflow weir in the overflow pool, thereby achieving the water storage and drainage effects similar to those of the existing mud-discharging wet well. The utility model has two access holes, so that related personnel can conveniently enter the mud well and the overflow pool according to the needs.
