Description
Technical Field
The invention belongs to the technical field of pipe jacking construction in the civil engineering industry, and particularly relates to an originating protection device used in a reinforced concrete pipe jacking pipeline.
Background
In the construction process of water supply and drainage pipeline engineering, pipe jacking construction is a common construction problem, particularly in construction of a rock stratum top pipe section, when jacking, vibration at the contact initial surface of a machine head cutter disc and the rock stratum is large, cracks are easily generated on the 1 st to 2 nd pipeline behind a pipe jacking machine, the pipeline is seriously crushed, the pipeline cannot be jacked continuously, and the influence of vibration is reduced successively along with the increase of jacking mileage of a subsequent pipeline. In order to prevent the reinforced concrete pipeline from generating cracks in the jacking process, reinforced net sheets for improving the strength of the concrete and encrypting the pipeline are generally adopted in site construction, so that the crack resistance of the reinforced concrete pipeline is improved. At present, the anti-cracking performance of reinforced concrete is increased, the pipeline is required to be customized again by manufacturers, the construction cost is greatly increased, the cost of unfavorable projects is controlled, and in the rock jacking process, the pipeline cannot be guaranteed to be free from cracks.
Disclosure of utility model
The utility model aims to provide an originating protection device used in a reinforced concrete pipe-jacking pipeline, so as to solve the problems in the background technology. The originating protection device comprises an upper steel ring piece, a right lower steel ring piece, a left lower steel ring piece, embedded nuts and rubber gaskets. Each steel ring piece in the protection device of the pipe body is tightly attached and fixed with the pipe body through bolts.
As an improvement, the end part of each steel ring piece is designed into a T shape, so that the pipe body is prevented from being in direct contact with the pipe jacking machine head; the steel ring piece, the end part of the pipeline and the inner wall of the pipeline are provided with rubber gaskets, so that vibration transmitted to the pipeline by the pipe jacking machine is effectively reduced.
The utility model has the following effects:
(1) The utility model provides a novel pipeline protection device which is easy to install and detach. The steel ring piece provided increases the rigidity strength of the end part of the pipeline and improves the cracking resistance. The end part adopts T-shaped design, so that the pipe jacking machine head and the pipeline can be prevented from being in direct contact, and the end part of the pipeline is prevented from being broken due to stress concentration.
(2) The steel ring piece, the end part of the pipe body and the inner wall of the pipe are provided with rubber gaskets, so that vibration transmitted to the pipe by the pipe jacking machine can be effectively reduced.

Detailed Description
The invention is described in detail below with reference to the following examples and the attached drawings:
as shown in fig. 1 to 4;
The utility model provides a protection device that originates for in reinforced concrete pipe-jacking pipeline, originates protection device in the pipe-jacking pipeline includes 3 arc steel ring pieces of end to end, steel ring piece includes upper portion steel ring piece 1-1, right side lower steel ring piece 1-2, left side lower steel ring piece 1-3, and every steel ring piece adopts fixed connection bolt 2-2, closely laminates and fixes pipeline inner wall rubber gasket 3-1, pipeline end rubber gasket 3-2 and body 4.
As the preferred implementation scheme of the implementation case, the end part of the steel ring piece is designed into a T shape, so that the pipe body is prevented from being in direct contact with the pipe jacking machine head; the steel ring piece, the end part of the pipeline and the inner wall of the pipeline are provided with rubber gaskets, so that vibration transmitted to the pipeline by the pipe push bench can be effectively reduced. When the upper steel ring piece 1-1, the right lower steel ring piece 1-2 and the left lower steel ring piece 1-3 are manufactured, the nut hole 5 on each steel ring piece is matched with the position and the size of the embedded nut of the pipeline. During the manufacturing process of the pipe body 4, the nut 2-1 is needed to be embedded and matched with the nut hole 5 on the steel ring piece.
The installation of the embodiment comprises the following steps:
(1) Installing rubber gaskets 3-1 and 3-2;
(2) Installing an upper steel ring piece 1-1, and tightly attaching and fixing the steel ring piece, the rubber gasket and the pipe body through a connecting bolt 2-2;
(3) And the right lower steel ring piece 1-2 and the left lower steel ring piece 1-3 are installed, and the steel ring piece, the rubber gasket and the pipe body are tightly attached and fixed through the connecting bolts 2-2.
