Detailed Description
The invention is further described with reference to the following figures and detailed description.
As shown in fig. 1, 2, 3 and 4, the buried pipeline installation method comprises the following steps:
a. a plurality of concave roller bed frame bodies 2 are arranged on the ground 1;
b. placing the buried pipelines 3 on the concave roller bed frame body 2, and sequentially connecting the buried pipelines 3 together;

c. and installing and fixing the buried pipelines 3 connected together underground.
In step a, in order to ensure that the buried pipes 3 connected together are on the same straight line, the centers of all the concave roller bed frame bodies 2 are on the same straight line.
In step b, the buried pipelines 3 are connected together by means of hot melting or welding. In order to facilitate the connection operation of the buried pipelines 3, the invention connects the buried pipelines 3 by arranging a winch device 4, a pipe bracket sleeve 5 and a pulley block. During connection, the pipe support sleeve 5 is arranged on the buried pipeline 3 on the outermost side, the winch device 4 penetrates through the pulley block to be connected with the pipe support sleeve 5, and the connected buried pipeline 3 is lifted by the winch device 4 and pushed by the winch device, so that connection work is facilitated.
In step c, the procedure of installing and fixing the underground buried pipeline 3 on the ground comprises the following steps: firstly, digging a foundation pit 6 on the ground 1, and enabling the buried pipelines 3 connected together to be parallel to the foundation pit 6; then the buried pipelines 3 connected together are placed into a foundation pit 6 through a power device 7; then fixing the buried pipeline 3 in the foundation pit 6 through a fastener 8; and finally, backfilling earthwork of the foundation pit 6. The power device 7 is a plurality of single-arm cranes which simultaneously lift the buried pipelines 3 connected together and place the buried pipelines into the foundation pit 6. The fastener 8 is a flat steel hoop 9 and a steel chisel 10, the flat steel hoop 9 is firstly clamped on the buried pipeline 3, and the steel chisel 10 penetrates through the flat steel hoop 9 to be fixed in the foundation pit 6, so that the buried pipeline 3 is fixed in the foundation pit 6.
When the existing underground buried pipeline 3 of the river 11 is installed, water in the river 11 needs to be drained firstly, then the foundation pit 6 needs to be dug out, finally, after the buried pipeline 3 is installed in the foundation pit 6, earthwork backfilling is carried out on the foundation pit 6, the number of processes is large, and the efficiency is low. In step c, the process of installing and fixing the buried pipeline 3 under the river 11 comprises the following steps: as shown in fig. 4, the shield drilling machine 13 is firstly connected with the buried pipeline 3, then the buried pipeline 3 is driven to move along the underground of the river 11 by the shield drilling machine 13, the buried pipeline 3 is installed in the underground of the river 11, and finally the shield drilling machine 13 is separated from the buried pipeline 3. The shield drilling machine 13 is used for drilling a foundation hole under the river 11 and installing the buried pipeline 3 in the foundation hole, so that water in the river 11 does not need to be pumped out, the working procedures are obviously reduced, and the installation efficiency is obviously improved. In order to ensure the connection strength of the shield drilling machine 13 and the buried pipeline 3, as shown in fig. 5, the shield drilling machine 13 is connected with the buried pipeline 3 through screw threads, and is reinforced at the screw threads through bolts 14, the number of the bolts 14 is 2-6, and the size of the connection end of the shield drilling machine 13 is large outside and small inside, so that the buried pipeline 3 can be connected conveniently.
