Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1 to 3, an underground pipeline protection device comprises two protection shells 1, wherein two ends of each protection shell 1 are respectively provided with a closed end plate 3, the central position in each protection shell 1 is respectively provided with a protection inner shell 2, two ends of each protection inner shell 2 penetrate out of the closed end plates 3, each protection inner shell 2 is of a semicircular structure, one side of each protection shell 1 is hinged through a hinge 4, the other side of each protection shell 1 is correspondingly provided with a plurality of screw fixing holes 5, and the corresponding screw fixing holes 5 after the movable sides of the two protection shells 1 are closed are locked through screws and nuts.

A plurality of reflective warning strips 6 are arranged on the outer wall of the protective shell 1 at intervals.

The protective housing 1 has a semicircular structure.

The inner diameter of the protective shell is 60mm, and the length is 80cm.

The inner diameter of the inner housing 2 is 25mm and the length is 1m.

The length of the portion of the inner shell 2 which passes out of the closed end plate 3 is 10cm.

The number of screw fixing holes 5 is 3.

As shown in fig. 4 to 5, the rain and sewage diversion project is generally to set new pipelines along the current road, the single-section length of the new rainwater pipeline 7 is 1500-5000m, the average excavation depth is 3m, and the underground pipeline 8 crossing the road generally exists every 50m, if the new rainwater pipeline 7 collides with the new pipeline, the underground pipeline 8 needs to be wrapped by adopting a protection device, so that the influence of the construction of the new rainwater pipeline 7 on the new pipeline is avoided.

The protective outer shell 1 and the protective inner shell 2 can be made of plastic materials, so that the cost is saved. The underground pipeline 8 which is manually dug out is wrapped by the openable protective outer shell 1 and the protective inner shell 2. When the excavator excavates, on one hand, the protective shell 1 is externally provided with the reflective warning strip 6, so that the function of reminding a driver of the excavator is achieved; on the other hand, if the pipeline is accidentally touched by accident, the protection outer shell 1 is touched firstly, then the protection inner shell 2 is touched, and double-layer protection is formed for the underground pipeline 8, so that the risks of electric leakage and air leakage are effectively reduced.

The protective shell 1 is divided into two halves, one end of the protective shell is connected by a movable hinge 4 and used for opening and closing, and the other end of the protective shell is locked by a screw and a nut. Taking the 10kV buried high-voltage wire frequently encountered in the field as an example, the diameter of the cable is between 16 and 24mm according to the current intensity. When in installation, the protective outer shell 1 is firstly opened, and the underground pipeline 8 is wrapped by the protective inner shell 2. If the underground pipe 8 is too thin, the inside of the protective inner housing 2 is filled with rubber gaskets, and then the protective outer housing 1 is integrally closed and locked, thus completing the installation.

The modularized underground pipeline protection device forms double-layer protection for the underground pipeline 8, and solves the problem that the traditional underground pipeline 8 is easily damaged by soil and machinery. And the underground pipeline 8 is wrapped and reinforced in sections through the modularized underground pipeline protection device, the whole module is divided into a plurality of unit components, and the unit components can be independently detached and replaced if damaged, so that the whole waste is needed when the protection device is damaged, the construction loss is reduced, and a good pipeline protection effect is achieved.

While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is intended to cover various modifications, either made by the method concepts and technical solutions of the utility model, or applied directly to other applications without modification, within the scope of the utility model.
