Description
Technical Field
The utility model belongs to the technical field of tunnel and underground works construction, concretely relates to push pipe brim of a hat device.
Background
The pipe jacking construction is a common non-excavation construction method in water conservancy and hydropower construction, namely under the condition of not excavating the earth surface, the friction force between a pipeline and surrounding soil is overcome by means of jacking equipment in a working pit, the pipeline is jacked into the soil according to a designed gradient and the earthwork is transported away, after one section of pipe is jacked into the soil layer, the lower second section of pipe is jacked continuously, the principle is that a tool pipe or a heading machine is pushed into a receiving pit from the working pit through the soil layer by means of the thrust of a main jacking oil cylinder, the space between the pipelines, the relay and the like, and the pipeline is buried between the two pits after following the tool pipe or the heading machine. The pipe jacking operation can be carried out by manual excavation jacking and muddy water balance excavation jacking for different soil materials. In the manual jacking operation construction, an operator is required to enter a jacking pipe to carry out the work of digging, clearing and the like, and due to the instability of gravel soil, the phenomenon of collapse and the like easily occurs, or the phenomenon of digging material to flow into the area with abundant underground water occurs, so that the guarantee of the safety of the operator is the extremely important work in the jacking pipe operation. At present, in the only pipe jacking operation construction method, a grid is applied to a pipe opening to protect operating personnel in the pipe jacking, but the measure can cause great influence on the construction and increase the project construction cost. In order to meet the requirement of safe jacking operation under the condition of gravel geology and save project cost, the pipe jacking brim device is developed by combining the actual condition of a project site.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome above-mentioned prior art's shortcoming, provide an economic safety, guarantee operation personnel's safety, reduced the push pipe brim of a hat device of cost when push pipe advances.
The technical scheme for solving the technical problems is as follows: the pipeline is provided with a sleeve outside, one end of the sleeve is provided with a baffle, the lower side of the baffle is provided with a fixing frame, and the outer edge of the baffle is provided with a protective layer.
The utility model discloses a terminal surface of baffle is the arc plate of downwarping, and the centre of a circle is located the below of arc plate, and the central angle of arc plate is 135 ~ 225 °, and the radius of arc plate is 2 with the diameter ratio of pipeline: 5-3: 5.
The utility model discloses a be provided with the sleeve outside the pipeline, be provided with the baffle on the sleeve, in the baffle can prevent that the outer soil of pipeline from gushing into the pipeline, protection operation personnel and equipment, the baffle also plays the supporting role to the soil body on pipeline upper strata simultaneously, and protection concrete pipe can not produce local destruction at the whole atress of pipe jacking in-process. The baffle downside is provided with the mount, and the baffle outward flange is provided with the protective layer, and the protective layer can ensure that the pipeline can not produce local distortion because of the atress inequality at the in-process baffle of advancing, reduces the resistance that the pipeline pushed up into the soil body. The utility model discloses can play certain supporting role to upper soil, the guarantee pipeline is gone on safely when the operation is advanced in the top, does not influence the operation personnel construction simultaneously, makes things convenient for the operation personnel to come in and go out. The utility model has the advantages of simple structure, low cost and wide application range, and is suitable for various soil working faces.
