Embodiment 1

[0023] Such as Figure 1-4 As shown, an automatic cleaning type sewage discharge device for underground engineering construction includes a storage box 1 and a cylindrical collection box 2. The storage box 1 and the collection box 2 are connected through the sewage outlet 3. The sewage outlet 3 includes a 2. The upper opening at the bottom and the lower opening provided on the upper end of the storage box 1, the upper opening and the lower opening correspond to each other and communicate with each other, and the upper and lower openings together form a tapered opening with a small top and a large bottom, which is conducive to the rapid discharge and collection of impurities. The upper end of the box 2 is provided with a water inlet pipe 4, and a drain pipe 5 is provided on the side wall. The inner container 2 is rotationally sealed and connected with an inner container 6 with an open end. The inner container 6 is fixedly connected with a partition 7 along its axial direction. ...

Embodiment 2

[0028] Such as Figure 5 As shown, the difference between the present embodiment and Embodiment 1 is that: the storage box 1 is fixedly connected with a water filter plate 14 provided with an inclination; The part of the box 1 located at the lower side of the filter plate 14 is fixedly communicated.

[0029] In this embodiment, by setting the water filter plate 14, the dry-wet separation of impurities can be realized, which facilitates the recovery and treatment of impurities in the later stage, and, because the return pipe 15 is provided, the fluid in the drain pipe 5 flows rapidly, according to Bernoulli's principle It can be seen that the pressure in the drain pipe 5 is lower than the pressure of the return pipe 15, and under the action of the pressure difference, the drain pipe 5 will suck the sewage in the return pipe 15 and take the sewage away, thereby reducing the subsequent sewage treatment process, and at the same time , the storage space of the storage box 1 can al...

Abstract

The invention belongs to the field of underground engineering, and particularly relates to an automatic cleaning type underground engineering construction sewage discharge device, which comprises a storage box and a cylindrical collection box, wherein the storage box is communicated to the collection box through a sewage discharge port, a water inlet pipe is arranged at the upper end of the collection box, a water discharge pipe is arranged at the side wall of the collection box, a liner with an opening end is rotationally connected in the collection box in a sealed mode, and is fixedly connected to a partition plate in the axis direction of the liner, the liner is divided into an upper water discharge cavity and a lower water discharge by the partition plate, circulating holes are formedin the positions, corresponding to the water inlet pipe, of each water discharge cavity, filtering plates are connected in each water discharge cavity in a sliding and sealing mode, and are perpendicular to the axis direction of the liner, a counterweight roller is rotationally connected to the outer side wall, away from the opening end, of the liner, and a connecting strip is wound around the counterweight roller. According to the invention, by arranging the upper water discharge cavity and the lower water discharge cavity, water can be conveyed alternately, and the sewage discharge pipe is not required to be closed during impurity cleaning, so that the non-stop operation can be achieved, and the sewage discharge efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of underground engineering, in particular to an automatic cleaning sewage discharge device for underground engineering construction. Background technique [0002] Underground engineering refers to activities related to construction and construction below the surface, such as tunnel excavation. During the construction of underground engineering, it is often necessary to discharge underground construction sewage in time to ensure the normal progress of construction. [0003] During the construction of underground projects, the sewage contains more large particles of hard impurities such as small stones. During the process of sewage discharge, it is easy to block the pipeline, which not only seriously affects the drainage efficiency, but also easily damages the sewage. In addition, because the construction space of underground engineering is generally narrow and long, it also brings greater difficulty to the dredging and...
