Technical Field

The invention relates to the technical field of water seepage prevention, in particular to a method for treating water seepage prevention of a rabbet pipe connecting port of a reinforced concrete pipe.

Background

Concrete pipes are pipes made of concrete or reinforced concrete in bulk and used for transporting fluids such as water, oil, gas, etc. The concrete pipe can be divided into four types, namely plain concrete pipe, common reinforced concrete pipe, self-stress reinforced concrete pipe and prestressed concrete pipe. For transporting fluids such as water, oil, gas, etc. Concrete pipes are classified into plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. According to the different inner diameters of concrete pipes, the concrete pipes can be divided into small-diameter pipes (with the inner diameter below 400 mm), medium-diameter pipes (with the inner diameter below 400 mm) and large-diameter pipes (with the inner diameter above 1400 mm). The pressure pipe can be divided into low pressure pipe and pressure pipe according to the difference of the water pressure bearing capacity of the pipe, and the working pressure of the pressure pipe is generally 0.4, 0.6, 0.8, 1.0, 1.2 MPa and the like. Concrete pipes are classified into plain pipes, spigot-and-socket pipes, and tongue-and-groove pipes, depending on the type of pipe joint. The joint forms comprise a cement mortar smearing joint, a steel wire mesh cement mortar smearing joint, cement mortar socket joints, rubber ring socket joints and the like.

After the ordinary reinforced concrete pipe rabbet pipes are connected, water seepage of the connecting ports is often caused due to the fact that the connecting positions are not sealed in place, the later maintenance cost is extremely high, long-time low-cost stable operation of related building facilities is not facilitated, a method for performing water seepage prevention treatment on the rabbet pipes is adopted, and the water seepage prevention effect is not obvious.
