Problems solved by technology
In factory buildings and industrial buildings, reinforced concrete structures, steel structures, or structures in which concrete is poured inside steel pipes are generally used for piling. However, piling with steel structures and reinforced concrete structures often has high cost and long installation time. Concrete structure and steel structure are easily corroded and oxidized by the external environment, thus greatly reducing the service life of the pile pipe

Embodiment Construction
[0014] Such as figure 1 , image 3 As shown, a piling pipe of the present invention includes a pipe body 1, a socket 2, and a socket 3. The inner diameter of the socket 2 is not less than the outer diameter of the socket 3, so that the socket of another pipe body can be inserted into the socket. The inner diameter of the socket 2 and the outer diameter of the socket 3 decrease from left to right, and smooth slopes are formed at the socket 2 and the socket 3 respectively, and the angles of inclination of the two slopes formed are the same. Preferably, the inclination angles of the slopes are all 12° to 14°. The angle of inclination is small, which greatly reduces the processing difficulty of the bevel at socket 2 and socket 3, simplifies the process, and provides great convenience for standardized mass production of pipe body 1, and the socket between two or more pipe bodies 1 2. The socket 3 has a large contact area when installed together, and the connection stability is be...

The invention relates to a piling tube for plants and other industrial buildings. The invention aims to provide the piling tube that is simple in structure and manufacturing technology, short in installing time, not prone to corrosion and long in service life. The piling tube provided by the invention comprises a tube body, a bellmouth and a socket, wherein the inner diameter of the bellmouth is not less than the outer diameter of the socket, the inner diameter of the bellmouth and the outer diameter of the socket are both gradually reduced from left to right, the bellmouth and the socket respectively form a smooth slope, and the inclination angles of the two slopes are the same.
Description
technical field [0001] The invention relates to the technical field of prefabricated piles or other structural components dedicated to foundation engineering, in particular to a piling pipe used in workshops and other industrial buildings. Background technique [0002] At present, domestic and foreign ductile cast iron pipes are often used in the field of water supply and drainage. The interface generally adopts anchor blocks embedded in rubber rings and mechanical structures such as pressure flanges and bolts are used to connect the pipe sockets together outside the joints. In factory buildings and industrial buildings, reinforced concrete structures, steel structures, or structures in which concrete is poured inside steel pipes are generally used for piling. However, piling with steel structures and reinforced concrete structures often has high cost and long installation time. Concrete structures and steel structures are easily corroded and oxidized by the external environ...
