Furthermore, each top bracing chamber is internally provided with a plurality of groups of top bracing devices.
Furthermore, the jacking device comprises a thin jack arranged in the jacking cavity along the width direction, an upper top plate of the thin jack is abutted to the lower surface of the arc-shaped upper top plate, a lower top plate of the thin jack is abutted to the upper surface of the arc-shaped lower top plate, and a height adjusting rod of the thin jack extends out of the jacking cavity.
The utility model has the advantages of simple structure and simple operation. Roof on by the arc, the arc top that roof and vertical connecting plate constitute under the arc props the thin piece and is convenient for fill in between interior steel pipe and the rubber overcoat when polyurethane foaming notes material link, later the rethread sets up the roof device in propping the cavity with the arc and props roof down and open under roof and the arc, thereby easily satisfy required foaming insulation layer thickness, steel pipe and rubber overcoat's both ends in can the shutoff simultaneously, be convenient for the implementation of polyurethane foaming notes material link in the formula heating power pipeline course of working of directly burying, it is quick, the both ends in effectual airtight foaming space, reduce the foaming material and leak outward, raise the efficiency and foaming capacity weight ratio, multiple spot position top props simultaneously and can effectively prevent that whole device from droing and causing the heavy object impact injury, ensure the quality of the formula heating power pipeline that directly buries that processing produced.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
As shown in fig. 1-3, the rubber jacket supporting mechanism for a direct-buried heat distribution pipeline of the present invention comprises an annular supporting body formed by splicing a plurality of arc supporting thin blocks 10 with the same structure, wherein the number of the arc supporting thin blocks 10 can be 4, 5 or 6; each arc-shaped top bracing thin block 10 consists of an arc-shaped upper top plate 101, an arc-shaped lower top plate 102 and a vertical connecting plate 103, wherein the upper edge of the vertical connecting plate 103 is vertically and fixedly connected to one side edge of the arc-shaped upper top plate 101, and the lower edge of the vertical connecting plate 103 is vertically and fixedly connected to one side edge of the arc-shaped lower top plate 102, so that a U-shaped structure (shown in figure 3) with a transverse section shape is formed, and a top bracing chamber 20 with an arc-shaped structure is formed in the middle part surrounded by the arc-shaped upper top plate 101, the arc-shaped lower; a top bracing device is arranged in the top bracing chamber 20, and a plurality of groups of top bracing devices can be arranged in each top bracing chamber 20, and the operation part of each top bracing device should extend out of the top bracing chamber 20. Specifically, the jacking device may be a thin jack 30 disposed in the jacking chamber 20 along the width direction, an upper top plate 301 of the thin jack 30 abuts against the lower surface of the arc-shaped upper top plate 101, a lower top plate 302 thereof abuts against the upper surface of the arc-shaped lower top plate 102, and a height adjusting rod 303 of the thin jack 30 extends out of the jacking chamber 20.
In addition, because the arc-shaped lower top plate 102 is attached to the outer wall of the inner steel pipe of the direct-buried heat distribution pipeline, and the arc-shaped upper top plate 101 is to be outwards propped up and propped up against the inner wall of the rubber outer sleeve of the direct-buried heat distribution pipeline, the arc length of the arc-shaped upper top plate 101 is slightly longer than that of the arc-shaped lower top plate 102, so that after each section of arc-shaped top propping thin block 10 is propped up, each section of arc-shaped upper top plate 101 can be just butted together to form a ring shape, and meanwhile, each section of arc-shaped lower top plate 102 can also be butted together to form a ring shape, so far as the gap between the vertical connecting plates 103 of two adjacent sections of top propping thin blocks 10 can be plugged.
In practical use, it should be noted that, because the arc length of the arc-shaped upper top plate 101 of the arc-shaped top bracing thin block 10 is slightly longer than that of the arc-shaped lower top plate 102, one arc-shaped upper top plate is needed to be operated in practical installation, namely, after the first arc-shaped top bracing thin block 10 is plugged between the inner steel pipe and the rubber outer sleeve, the upper top plate 301 of the thin jack 30 is jacked outwards by operating the height adjusting rod 303, so that the arc-shaped upper top plate 101 jacks the rubber outer sleeve outwards (as shown in fig. 4 and 5), and after the arc-shaped upper top plate 101 is jacked in place, the second arc-shaped top bracing thin block 10 can be plugged again and the same jacking operation is carried out; propping is carried out one by one until the whole rubber outer sleeve is propped up (as shown in fig. 6), and then the butt joint gap between two adjacent arc-shaped propping thin blocks 10 can be plugged in a welding mode; after all the installation and welding operations are finished, the subsequent polyurethane foaming and material injection operation can be carried out.
