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 work belong to the protection scope of the present invention.

Example (b):

referring to fig. 1 to 4, in an embodiment of the present invention, a cement culvert pipe mold for a utility tunnel includes: external mold 1, external mold 1 both ends are equipped with sealed lid 2, and sealed 2 inner walls of lid are equipped with sealing washer 3, sealed 2 inside snap rings 4 that are equipped with of lid, 1 top of external mold is equipped with

bolt hole

5 and 1 surface of external mold is equipped with

feed inlet

6, 1 inside centre form 7 that is equipped with of external mold, centre form 7 includes first centre form 701 and second centre form 702, the inside dead lever 8 that is equipped with of

centre form

7, 8 fixed surface welding of dead lever have connecting rod 9, 9 one end threaded connection of connecting rod has movable rod 10, the lug 11 embedding of 10 one ends of movable rod is located in 7 fixed welded embedded grooves 12 of inner.

The outer die 1 is composed of two half drums, one end of the outer die 1 is connected through a hinge, the other end of the outer die 1 is fixed through a bolt inserting bolt hole 5, and when the outer film 1 is fixed, the bolt is inserted into the bolt hole 5 to fix the outer film 1.

The diameter of the sealing ring 3 is equal to that of the inner wall of the sealing cover 2, when the sealing cover 2 is in threaded connection with the outer mold 1, the rubber ring 3 is extruded at two ends of the outer mold 1 and the inner mold 7, and therefore cement between the outer mold 1 and the inner mold 7 is sealed, and leakage of the cement is prevented.

Wherein, centre form 7 is that two first centre forms 701 and two second centre forms 702 cross combination form, and first centre forms 701 and second centre forms 702 junction are the Z type, when the shaping of cement culvert pipe, need dismantle centre form 7, unscrew earlier the movable rod of being connected with two second centre forms 702, make second centre forms 702 and cement culvert pipe separation, then unscrew the movable rod of being connected with two first centre forms 701, make first centre forms 701 and cement culvert pipe separation to reach the effect of whole centre forms 7 and cement culvert pipe separation.

Wherein, dead lever 8 locates centre department of centre form 7, and its welded connecting rod 9 in surface is a set of four, and four connecting rods 9 are the cross and arrange, and centre form 7 both ends are respectively a set of, and connecting rod 9 can stretch out and draw back the removal to first centre form 701 and second centre form 702 respectively, reaches the convenient effect of installation dismantlement.

The connecting rod 9 is smaller than the radius of the inner wall of the inner die 7, the first inner die 701 and the second inner die 702 can be moved by screwing the movable rod 10, and during disassembly, the second inner die 702 is moved by screwing the movable rod 10, and then the first inner die 701 is disassembled.

The working principle is that firstly, the snap rings 4 on the two sealing covers 2 are sleeved at the two ends of the fixed rod 8, the sealing covers 2 are screwed, the two ends of the outer mold 1 are fixed, meanwhile, bolts are inserted into the bolt holes 5 on the surface of the outer film 1 to further reinforce the outer mold 1, then, the first inner mold 701 and the second inner mold 702 are adjusted by rotating the movable rod 10, so that the first inner mold 701 and the second inner mold 702 are arranged to form a cylinder, then, cement slurry is filled between the inner mold 7 and the outer mold 1 from the feed inlet 6, finally, when the cement culvert is formed, the inner mold 7 and the outer film 1 need to be disassembled, the bolts in the bolt holes 5 are taken out, the sealing covers 2 are rotated to separate from the outer mold 1, so that the outer film 1 can be separated from the outer wall of the cement culvert, the second inner mold 702 is separated from the inner wall of the cement culvert by unscrewing the movable rod 10 supporting the second inner mold 702, and the movable rod 10 supporting the first inner mold 701 is unscrewed so that, thereby realizing the disassembly between the cement culvert pipe and the mould.
