A Simple Method of Adding Pre-buried Pipes

Abstract

The invention relates to a simple embedded pipe adding method which comprises the following steps: step 1, selecting the mounting position of an embedded pipe at the bottom or on the wall of a tank and marking the locating point; step 2, drilling at the locating point through a diamond tapping machine to form a mounting hole communicated with the inner cavity of the tank; step 3, coating the wall of the mounting hole with a mounting hole anticorrosion layer which is connected with an anticorrosion layer on the inner side surface of the tank wall; step 4, coating the outer wall of the embedded pipe with a resin glue mud layer; step 5, further coating the end surface of the embedded pipe and the inner side surface of the tank wall with a secondary anticorrosion layer, and covering the surface at the tail of the embedded pipe and the outer side surface of the tank wall with gridding cloth through brushing and sticking; step 6, putting into use after solidification of the mounting hole anticorrosion layer, the resin glue mud layer and the secondary anticorrosion layer. According to the simple embedded pipe adding method, the embedded pipe adding process can be simplified, the damage caused by tapping to the concrete structure of the tank body and the inner anticorrosion layer is smaller, processes like secondary grouting solidification and maintenance of concrete are avoided, the construction period is shorter, the operation is simple and convenient, and high easiness in construction is achieved.

Description

technical field [0001] The invention relates to the construction field, in particular to a simple method for adding pre-embedded pipes. Background technique [0002] For hydrometallurgy, the steel-concrete + FRP anti-corrosion tank is a relatively common equipment, which has the characteristics of high strength, low cost, long service life, and relatively simple construction. The pre-embedded pipe, as a part connecting the tank to the pump or other equipment, is embedded in the tank wall concrete at the bottom of the tank during the tank production process. According to the characteristics of the medium in the tank, the materials of the embedded pipes are different. Taking the zinc hydrometallurgy as an example, FRP anti-corrosion has the advantages of temperature resistance, wear resistance, corrosion resistance, and crystallization resistance. It is a relatively common anti-corrosion material for equipment. It is convenient to connect with the anti-corrosion layer in the ...

Problems solved by technology

After the concrete is solidified, remove the formwork, repair it and maintain it for a certain period of time. The stripped anti-corrosion layer 4a is re-painted with cloth and connected with the embedded pipe. The construction process steps are more complicated and the period is longer. , and the duration is longer
