There is a chute 6 close to the sewage outlet and the rainwater outlet in the shaft, and limit blocks are arranged at both ends of the chute; the water retaining cover 8 is arranged in the chute 6; the upper end of the shaft is provided with a crank handle 10 and a reel, 10 is connected with the bobbin transmission; one end of the linkage line 7 is fixed on the bobbin, and the other end is fixed on the water retaining cover plate 8. The width of the water retaining cover is slightly greater than the width of the sewage outlet and the rainwater outlet, and the height of the water retaining cover is also slightly greater than the height of the sewage outlet and the rainwater outlet, so that the water retaining cover can completely block the sewage outlet or the rainwater outlet. Under the action of the linkage line, the water-retaining cover can move up and down in the chute to block the sewage outlet and the rainwater outlet in rotation respectively, so as to realize the diversion of sewage and rainwater. Limiting blocks are provided at both ends of the chute to limit the movement range of the water retaining cover in the chute.

Among them, the diameter of the water inlet is 400mm, and the diameter of the water outlet is 300mm. The distance between the water inlet and one water outlet is 300mm from the bottom of the wellbore, the distance between the bottom of the other water inlet and the top of the water inlet is 300mm, and the height of the wellbore is 1500mm.

On the basis of the above embodiment, because the position of the water retaining cover is manually controlled, the sewage outlet can also be relocated above the rainwater outlet, which does not affect the realization of the utility model.

Among them, the well shaft can be prefabricated by the factory, and it is integrally formed with plastic to ensure that there is no possibility of leakage at the connection between the well, the water inlet and the water outlet. The chute is made of stainless steel, and the water retaining cover is made of tiles. The above-mentioned structure not only has low cost, no rust, and guaranteed quality, but also saves the cumbersome procedures of formwork support, maintenance, and disassembly at the construction site, reduces construction pollution, and achieves the advantages of high quality, time saving, high efficiency, portability, and environmental protection. .

The working principle of the manual inspection well is as follows:

When the weather is sunny or the rainfall is small, refer to Figure 3, lift the water retaining cover 8 through the crank handle 10, and control it to cover the rainwater outlet 4, domestic sewage enters the inspection well through the water inlet 3, and then discharges through the sewage outlet 5 to Constructed wetlands and other treatment pools are discharged to nearby rivers after treatment. When the rainfall is heavy, refer to Figure 4, lower the water retaining cover 8 by shaking the handle 10, so that the water retaining cover 8 covers the sewage outlet 5, and the water level in the inspection well rises gradually until it is higher than the bottom of the rainwater outlet 4. The water in the well is directly discharged to the nearby river through the rainwater outlet 4. After the rain stops, shake the crank handle 10 to drive the water retaining cover 8 to move upward, and place the water retaining cover 8 at the rainwater outlet 4 again, so that domestic sewage can flow from the sewage outlet 5 discharge.

The connection between the water inlet, the water outlet and the external water pipe is inlaid. A PVC hard pipe with the same diameter as the plastic pipe is used to connect the plastic pipe. After cutting the plastic pipe, put it on the hard pipe and tighten it with iron wire. , to ensure that the connection is tight and reliable without water seepage.

The well shafts used for rain and sewage diversion are produced on a large scale in the factory according to the general design drawings, which can not only ensure the quality of the components and improve the accuracy of the components, but also can be directly installed on the construction site, achieving labor saving, high efficiency, lightness, convenient transportation and installation, and construction. Pollution etc. Using the same plastic material and the same basic form as the drainage pipe can effectively solve the problem of the interface connection between the pipe and the well, avoid uneven settlement, greatly improve the impermeability of the pipe and the well, and benefit the long-term safety of the drainage pipe use.
