Portable discharge pipe device and method suitable for underground engineering water disaster treatment

Abstract

The invention discloses a portable water drain pipe device and method applicable to underground construction water disaster treatment. The portable water drain pipe device comprises an end sleeve, a middle sleeve, a bottom sleeve and a support; the end sleeve, the middle sleeve and the bottom sleeve are connected through threads; a first filter net is arranged at the connecting position of the end sleeve and the middle sleeve, a second filter net is arranged at the connecting position of the middle sleeve and the bottom sleeve, and a third filter net is arranged at an outlet of the bottom sleeve; the support is installed nearby a water outlet of the end sleeve and comprises a trapezoidal frame with a trapezoidal cross section, a rotary shaft is connected to the top of the trapezoidal frame, and a stainless steel circular ring is driven by the rotary shaft to rotate to achieve angle adjusting of the stainless steel circular ring; and a rotary button is arranged on the stainless steel circular ring and can achieve fixing of the rotary button and the sleeves.

Description

technical field [0001] The invention relates to a drain pipe device, in particular to a convenient drain pipe device and a drainage method suitable for underground engineering water disaster treatment. Background technique [0002] With the vigorous development of underground engineering, in the process of tunnel excavation, the occurrence of water inrush disasters shows an increasing trend. Immediately after a disaster occurs, it is a common method for emergency treatment of inrush water disasters to quickly carry out back pressure and lay out pressure relief pipes (or drainage pipes). But at present, the main problems are as follows: [0003] 1. The currently used pressure relief pipes are all ordinary iron pipes, which are extremely irregular in diameter and length, and cannot be reused, resulting in a great waste of resources. [0004] 2. Most of the filter screen material is cloth, the mesh size is random, and iron wire is mostly used to bind the nozzle. When the wate...

AI Technical Summary

Problems solved by technology

[0003] 1. The currently used pressure relief pipes are all ordinary iron pipes, which are extremely irregular in diameter and length, and cannot be reused, resulting in a great waste of resources

[0004] 2. Most of the filter screen material is cloth, the mesh size is random, and iron wire is mostly used to bind the nozzle. When the water flow is large, it is easy to be washed away; when the mud content or sand gravel is relatively high For a long time, it is very easy to cause the nozzle to be blocked, resulting in the counterpressure soil being washed away again

[0005] 3. In order to prevent the pressure relief pipe from moving down, sandbags are generally used as the lower support at the nozzle attachment of the pressure relief pipe. The sandbag support effect is not ideal and will increase the workload for no reason
