Multi-rod piping clip

Abstract

The invention relates to a multi-rod piping clip which comprises a mainshaft (1), a base (2) and a spring seat (4) that are respectively arranged at two ends of the mainshaft (1), wherein the mainshaft (1) arranged between the base (2) and the spring seat (4) is sleeved with a sliding seat (3), and the mainshaft (1) between the spring seat (4) and the sliding seat (3) is sleeved with a mainshaft pressure spring (5); a plurality of outwards-radiated expansion rods (10) are evenly arranged on the sliding seat (3), and the tail end of each expansion rod (10) is articulated with the sliding seat (3); the base (2) is provided with a plurality of support rods (7) which are matched with the expansion rods (10), wherein the rear end of each support rod (7) is articulated with the base (2), and the front end thereof is articulated with the middle part of each expansion rod (10); and a locking mechanism is arranged between the mainshaft (1) and the sliding seat (3). The multi-rod piping clip can carry out blocking and plugging on a piping water-leakage channel conveniently.

Description

technical field [0001] The invention relates to a rescue device in the field of dam flood control engineering, in particular to a device for piping rescue. Background technique [0002] The existing dikes in my country have disadvantages such as poor embankment foundation conditions and poor embankment filling quality. Once floods occur, dikes may have the possibility of piping, landslides and other dangerous situations. At present, most of the treatment of piping is to rescue the piping outlet on the back water surface of the embankment. The principle of rescue and protection is to stop the gushing water from carrying sand, and leave a way out for water seepage. The emergency protection methods mainly include the following types: filter surrounding wells, filter layer glands, water storage and back pressure (commonly known as water basins), etc. The implementation of these methods is time-consuming. In addition, it is also possible to manually dive into the water and plac...

Problems solved by technology

The emergency protection methods mainly include the following types: reverse filter surrounding well, reverse filter layer gland, water storage and back pressure (commonly known as water basin), etc. The implementation of these methods is time-consuming

In addition, it is also possible to manually dive into the water and place a pot to block the pipe hole. This method has low reliability and is very dangerous to divers.

There is also a method of using a single expansion bag to block the piping, which also relies on the diver to send the expansion bag into the piping hole, and then the diver opens the expansion bag. However, relying solely on the expansion bag to block the piping is easy to be washed away by the water flow, and the reliability is poor. , is not conducive to the continued filling of other materials
