Embodiment Construction

[0005] Process a pipe 1 with the same diameter as the proposed tunnel, and this pipe 1 can be made of steel or reinforced concrete; it can be one or several connected together. A plurality of holes 3 with switches are left on the inner side of the contact part between the bottom of the pipeline 1 and the river bed 2, and the water pumps 4 are respectively connected to these holes, and the water pump 4 injects water into the holes 3 with switches to flush the joints of the pipeline 1 and the river bed 2. Silt, because there is no support of sediment, the pipeline 1 sinks into the river bed 2, and the tunnel is formed. In order to adjust the sinking speed of the pipeline 1 at different positions and the angle with the axis, the outer side of the hole 3 should be made into a horseshoe shape, and can rotate 360° around the axis of the hole, and a plurality of height-adjustable steering plates 5 are also installed. Adjust to the length that board 5 stretches out, and the slow of si...

Abstract

The invention discloses a method for building a tunnel on a sediment river. At present, the tunnel is mostly built on the lower part of the river by adopting a digging mode, but the water is difficult to stop, and the construction has high difficulty, requires long period and sometimes affects the navigation of the river. According to the method, a conduit with the same diameter as the tunnel is processed, a plurality of holes with switches are reserved on the part where the conduit is connected with the river bed, water pumps are respectively connected to the holes, and the water pumps inject water to the holes with the switches to flush the sediment on the part where the conduit is connected with the river bed, so that the conduit is sunken to the river bed and the tunnel is formed.

Description

technical field [0001] The invention belongs to the construction field, and specifically relates to a method for building a tunnel in a sediment channel. Background technique [0002] At present, excavation is mostly used in the construction of tunnels in the lower part of the river. Due to the difficulty of blocking water, the construction is difficult and the construction period is long, which sometimes affects the navigation of the river. Contents of the invention [0003] The present invention is to process a pipeline with the same diameter as the tunnel, and leave a plurality of holes with switches at the part connected with the river bed, and connect water pumps to these holes respectively, and the water pump injects water into the holes with switches, and flushes the pipeline to connect with the river bed The sediment in the part makes the pipeline fall into the river bed and the tunnel is formed. Description of drawings [0004] Accompanying drawing is the schem...
