Problems solved by technology

Among them, the steel cylinder concrete pipe, due to the large opening of the joint, the external mud and sand are easy to enter the joint, which makes it impossible to correct the deviation and affects the sealing performance of the joint. At the same time, it is not suitable for long-distance jacking between the pipes
In addition, the steel cylinder concrete pipes in the prior art still have uneven grouting, and the soil around the pipes has a great impact on the surrounding environment

Abstract

The invention discloses a steel cylinder concrete top pipe and a connecting method thereof. The steel cylinder concrete top pipe comprises an inner-layer reinforcing mesh, a steel cylinder, pipe core concrete, an outer-layer reinforcing mesh, a socket, a jack, an outer steel jacket, an anchor bar, a groove, an O-shaped sealing ring, a steel ring and a wedge-shaped sealing ring. The connecting method comprises the following steps of: adopting two steel cylinder concrete top pipes, mounting a wooden gasket on the end part of the socket of the first steel cylinder concrete top pipe, and adopting a pushing method to push the jack of the second steel cylinder concrete top pipe into the socket of the first steel pipe concrete top pipe; and enabling the second steel cylinder concrete top pipe to connect to the first steel cylinder concrete top pipe in a sealing mode through the O-shaped sealing ring and the wedge-shaped sealing ring. The steel cylinder concrete top pipe is relatively good in sealing performance, is uniform in grouting, is suitable for long-distance pushing and is small in influence on environment.

Description

technical field [0001] The invention relates to the technical field of steel cylinder concrete pipes, in particular to a steel cylinder concrete pipe jacking and a connection method thereof. Background technique [0002] At present, the pipe jacking pipes commonly used in the field of water supply and drainage at home and abroad include steel pipes, F-type joint reinforced concrete pipes, steel cylinder concrete pipes, and prestressed steel cylinder concrete pipes. Among them, the steel cylinder concrete pipe, due to the large opening of the joint, the external mud and sand easily enter the joint, which makes it impossible to correct the deviation and affects the sealing performance of the joint. At the same time, it is not suitable for long-distance jacking between the pipes. In addition, the steel cylinder concrete pipe in the prior art still has uneven grouting, and the soil around the pipe has a great impact on the surrounding environment.
