In order to achieve the above purpose, the technical scheme of the invention is as follows:

A combination of equipment inspection well comprises a combined inspection well and an inspection well, comprising a well body, an overflow well cover and an inspection well cover, wherein the upper end of the well body is provided with an overflow well cover, A manhole cover, wherein the overflow manhole cover > and the manhole cover are laid and fixed on a concrete beam, and the well body is provided with a water inlet of a perforated collecting pipe and an outlet of a water outlet of a reservoir.

Furthermore, the base of the well body is compacted with plain soil, the compaction coefficient is greater than or equal to 93%, a C20 concrete cushion with a thickness of 150mm and a waterproof cement mortar with a thickness of 20mm are paved, and the periphery of the well body is paved with MU10 bricks, and the waterproof cement mortar with a thickness of 20mm is plastered to the top of the well.

Furthermore, the water outlet pipe of the reservoir is a UPVC pipe.

Furthermore, the water inlet pipe of the perforated collecting pipe is one of

HDPE, UPVC and MPVC pipes, and the perforated collecting pipe is distributed with perforated collecting pipe holes, the diameter of which is 3-5mm, and the hole spacing of which is 10-15mm at the 45°-degree angle between the lower side of the pipe and the vertical plane.

The technical scheme provided by the invention has the beneficial effects that:

The invention relates to a combination of equipment inspection well, which combines the inspection well with the inspection well to form a combination of equipment inspection well. Rainwater with different filter materials is collected into the combined equipment inspection well through a perforated collecting pipe, and the water quality of the water inlet of the inspection well can be sampled and flow monitoring equipment can be installed through the manhole cover,

Rainwater from low-impact development facilities such as gardens, dry streams and biological detention ponds will flow into the combined equipment monitoring inspection well through the overflow port. The combined installation of the inspection well cover and the overflow well cover expands the space of the inspection well, which can conveniently sample the filtered and purified rainwater quality and monitor the flow of rainwater. The rainwater collected by the combined equipment monitoring inspection well will flow into the reservoir > through the outlet for pouring wine into green space and washing out.

The invention relates to a combination of equipment inspection well, which adopts a combined structure design, has a simple structure, effectively improves the space utilization rate of the inspection well, and better meets the work needs of rainwater overflow, equipment maintenance, rainwater sampling and the like.

DESCRIPTION OF THE INVENTION

In order to make the purpose, technical scheme and advantages of the invention clearer, the example of the invention will be further described in detail with reference to the attached figures.

As shown in Figure 1 and Figure 2. A combination of equipment inspection well comprises a combined inspection well and an inspection well, which comprises a well body 1, an overflow well cover 2 and an inspection well cover 3, The upper end of the well body 1 is provided with an overflow manhole cover 2 and an inspection manhole cover 3, The overflow manhole cover 2 and the inspection manhole cover 3 are laid and fixed on the concrete beam 6, and the well body 1 is internally provided with a perforated collecting pipe water inlet 4 and a > reservoir water outlet 5.

Furthermore, the base of the well body 1 is compacted with plain soil, the compaction coefficient is greater than or equal to293%, a C20 concrete cushion with a thickness of 150mm is laid, and a waterproof cement mortar with a thickness of 20mm is applied to the top of the well. MU10 bricks are laid around the well body 1, and the waterproof cement mortar with a thickness of 20mm is applied to the top of the well.
