Large pipe shed construction method by using Luoyang shovel

Abstract

The invention provides a large pipe shed construction method by using a Luoyang shovel. The large pipe shed construction method by using the Luoyang shovel comprises the following steps: (1), measuring the elevation of the center line of a pipe shed according to a design drawing; (2), digging a working pit according to the measured elevation, and establishing a work room required by excavation of the Luoyang shovel; (3), applying a guide pipe, and locating the Luoyang shovel and the pipe shed; welding and reinforcing the guide pipe according to the designed position of the pipe shed, wherein the location of the guide pipe is defined according to engineering geological conditions, pore forming length and pipe diameter; sleeving the Luoyang shovel in the guide pipe which is inclined upwards; (4), crossly implementing a pore forming operation and a pipe shed jacking operation in the conventional large pipe shed construction technique, wherein an excavation surface of the Luoyang shovel is ahead of the pipe shed by 2-6 m, and the pipe shed follows up and is jacked, so that a pipe following technique is realized; (5), realizing deviation rectification by properly regulating the shoveling angle of the Luoyang shovel during excavation. The large pipe shed construction method by using the Luoyang shovel has a simple process and is easy to construct; through the adoption of the large pipe shed construction method, simplicity, economy and high efficiency of pipe shed construction in the tunnel and underground engineering advance support technique can be realized, and the normal construction of tunnels and underground engineering is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a Luoyang shovel construction method for a large pipe shed. Background technique [0002] With the rapid development of social economy, the increasingly tense ground transportation environment and the growing demand for transportation have prompted the construction of underground projects, shallow buried tunnel projects, municipal water conservancy pipelines, and urban underground sidewalks. This poses new challenges to structural design and construction safety. The advanced support technology of pipe shed is an effective means to solve this problem. The working principle of the pipe shed construction technology is to drill holes at a certain distance in the horizontal direction above the structure to be constructed, and then push into the seamless steel pipe. Seamless steel pipes are drilled according to certain rules to form floral tubes. With the help of the pr...

Problems solved by technology

[0005] 1. In the prior art, the MKD-5 drilling rig is used as the drilling tool. In order to meet the performance of the drilling rig and the space for the operator, a larger working room is required

And eventually the studio often needs to be demolished

Therefore, there is a great demand for manpower and material resources, which has a great impact on the construction progress.

[0006] 2. The MKD-5 drilling rig is often used in the prior art. After the pipe jacking operation is completed after all the drilling operations are completed, the hole wall will converge and deform due to the inability to apply support to the hole wall in time, resulting in hole collapse.
