In non-circular shield structure or special shield tunnel interval, for the bearing capacity that improves section of jurisdiction need to be arranged steel plate at the internal and external cambered surface of section of jurisdiction sometimes.If adopt the Grouting Pipe in traditional concrete pipe sheet, cannot abolish the steel plate of extrados.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of Grouting Pipe structure being embedded in advance in clad pipe sheet is provided, this Grouting Pipe structure is passed through the upper and lower mouth of pipe of Grouting Pipe respectively with extrados steel plate and intrados Plate Welding, and by the upper orifice place bonding cover plate in Grouting Pipe, to realize the normal slip casting in the compound section of jurisdiction with extrados steel plate and shutoff waterproof to Grouting Pipe.
The utility model object realizes and being completed by following technical scheme:
A kind of Grouting Pipe structure being embedded in advance in clad pipe sheet, described compound section of jurisdiction comprises concrete structure and is covered in respectively extrados steel plate and the intrados steel plate on extrados and intrados, it is characterized in that running through and being embedded with Grouting Pipe in described compound section of jurisdiction, the upper and lower mouth of pipe of described Grouting Pipe respectively with described extrados steel plate and intrados Plate Welding.
Upper orifice place in described Grouting Pipe is fixed with the cover plate suitable with described spout diameter through cementing agent.
Described Grouting Pipe by steel pipe and the steel pipe socket that is socketed on respectively the upper and lower mouth of pipe of described steel pipe form.
Described cover plate comprises steel plate and is covered on the PVC cover plate on described steel plate.
The lower nozzle of described Grouting Pipe disposes pipe plug, and described pipe plug and described Grouting Pipe lower nozzle internal diameter are suitable.
The lower nozzle internal face of described Grouting Pipe has screw thread.
The utility model has the advantages that, simple in structure, quick construction is convenient, the upper and lower mouth of pipe of Grouting Pipe is respectively with extrados steel plate and intrados Plate Welding, and at the upper orifice place of Grouting Pipe bonding cover plate, water-tight is functional, can make Grouting Pipe in the time carrying out grouting behind shaft or drift lining, backs down easily cover plate and carries out slip casting.
Brief description of the drawings
Fig. 1 is the Grouting Pipe schematic diagram in ordinary concrete section of jurisdiction;
Fig. 2 is the Grouting Pipe structural representation being embedded in advance in the utility model in clad pipe sheet;
Fig. 3 is the local enlarged diagram of Grouting Pipe upper orifice in the utility model.
Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Fig. 1-3, in figure, mark 1-11 is respectively: Grouting Pipe 1, compound section of jurisdiction 2, extrados steel plate 3, PVC cover plate 4, steel plate 5, steel pipe 6, steel sleeve 7, steel sleeve 8, intrados steel plate 9, pipe plug 10, cementing agent 11.
Embodiment: as shown in Figure 2,3, the present embodiment is specifically related to a kind of Grouting Pipe structure being embedded in advance in clad pipe sheet, in the inside and outside cambered surface of this compound section of jurisdiction, be coated with respectively intrados steel plate 9 and extrados steel plate 3, by adopting the Grouting Pipe built-in fitting of brand new to solve the problem that is coated with the grouting behind shaft or drift lining inconvenience of steel plate in the inside and outside cambered surface of compound section of jurisdiction 2.
As shown in Figure 2,3, this Grouting Pipe runs through and is embedded in advance in clad pipe sheet 2, formed by three sections of tube couplings, specifically comprise steel pipe 6, be set in the steel sleeve 7 of steel pipe 6 upper orifices and be set in the steel sleeve 8 of steel pipe 6 lower nozzles, for the convenience of management processing, steel sleeve 7 and 8 can adopt the sleeve pipe of same type, and the external diameter of steel pipe 6 is identical with the internal diameter of steel sleeve 7 and 8, steel sleeve 7 and steel sleeve 8 be set on the two ends mouth of pipe of steel pipe 6 after by welding to form overall Grouting Pipe; This Grouting Pipe runs through compound section of jurisdiction 2, its two ends are respectively with welding between extrados steel plate 3 and intrados steel plate 9, and the upper and lower mouth of pipe of Grouting Pipe is mutually concordant with intrados steel plate 9 with extrados steel plate 3, in order to ensure validity and compound section of jurisdiction 2 internal and external cambered surfaces smooth of welding, groove has all been cut in order to welding in the two ends of steel sleeve 7 and 8; In order to prevent that compound section of jurisdiction 2 water and soil when assembled from entering tunnel internal, need to take certain close measure, because steel pipe 6 has certain wall thickness, therefore on the internal face of steel sleeve 7, be formed with a cushion cap, on this cushion cap, be furnished with the double-layer cover plate jointly being formed by steel plate 5 and PVC cover plate 4, fixing through cementing agent 11 between the internal face of this double-layer cover plate and steel sleeve 7, its light plate 5 can effectively make up the problem of the strength of materials deficiency of PVC cover plate 4, adopts PVC cover plate that the shutoff reliability of Grouting Pipe is improved simultaneously; On the internal face of steel sleeve 8, there is screw thread, can connect grouting equipment.
