Description
Technical field
The utility model belongs to jacking construction field, and the position technology of pressure is born suitable for major trunk roads, road surface bearing capacity
Field, more particularly to a kind of concrete sleeve jacking construction structure.
Background technology
At present, in water supply and sewage work Zhong Chuan highways, river course, heavy construction, push pipe operation is typically taken, in order to hold
By the enough bearing capacity in top of constructing, steel pipe operation is typically taken, but due to being rubbed caused by steel pipe operation process and soil layer
The anticorrosive coat that power is easily destroyed top layer is wiped, reduces the service life of steel pipe.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, and provides a kind of simple in construction, easy to use, contracting
Casual labourer's phase, the bearing capacity for increasing pipeline, there is the concrete sleeve jacking construction structure of high practical value.
The technical solution of the utility model is：A kind of concrete sleeve jacking construction structure, including inner tube and outer tube, it is described
Inner tube and the pipe diameter size of outer tube selected according to construction condition, it is characterised in that：Described outer tube caliber is inner tube pipe
1.5-2 times and the arranged concentric in footpath；Base is provided between described outer tube and inner tube；Described base is located at the bottom in outer tube
Portion, lower end are that the arcuate structure that matches with the internal diameter of outer tube, upper end are provided with the trapezoidal groove to match with the external diameter of inner tube；
Described trapezoidal chassis interior is disposed with reinforced mesh；Described reinforced mesh is made up of arch steel and transverse steel
Network structure；
Waling is uniformly mounted between described outer tube docking pipe seam；The top of described waling and steel
Muscle mesh sheet is connected as one；
Described base is to be connected the casting on the whole formed with reinforced mesh on the top of waling by concrete
Form.
Described waling is arranged according to the modes of 16~18@of φ 200.
Described reinforced mesh is to be arranged by arch steel with transverse steel according to the modes of 8~10@of φ 200.
Concrete grade is identical used by concrete grade and pipeline used by described base.
Beneficial effect is caused by this programme：Generally, the utility model has simple in construction easy to use, by sleeve pipe
Operation instead of steel pipe operation, ensure that the normal construction of push pipe operation, considerably increase security and the carrying of pipeline operations
Power, increase pipeline service life, there is the advantages of high practical value.

Embodiment：
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1-3：A kind of concrete sleeve jacking construction structure, including inner tube 1 and outer tube 2, described inner tube 1
Selected with the pipe diameter size of outer tube 2 according to construction condition, it is characterised in that：The described caliber of outer tube 2 is the caliber of inner tube 1
1.5-2 again and arranged concentric；Base 3 is provided between described outer tube 2 and inner tube 1；Described base 3 is located in outer tube 2
Bottom, lower end be the arcuate structure 6 that matches with the internal diameter of outer tube 2, upper end be provided with match with the external diameter of inner tube 1 it is trapezoidal
Groove 7；Reinforced mesh 4 is disposed with inside described trapezoidal base 3；Described reinforced mesh 4 is by arch steel 9 and horizontal steel
The network structure that muscle 8 is formed；
Described outer tube 2 is uniformly mounted with waling 5 between docking pipe seam；The top of described waling 5
It is connected as one with reinforced mesh 4；
Described base 3 is to be connected pouring on the whole of being formed with reinforced mesh 4 on the top of waling 5 by concrete
Casting forms.
Described waling 5 is arranged according to the modes of 16~18@of φ 200.
Described reinforced mesh 4 is to be arranged by arch steel 9 with transverse steel 8 according to the modes of 8~10@of φ 200.
Concrete grade is identical used by concrete grade and pipeline used by described trapezoidal base 3.
The utility model Specific construction mode：First the jacking pipe construction process jacking outer tube by, outer pipe construction finish examination
Afterwards, unwrapping wire is measured in outer tube, trapezoidal base is poured in outer tube inner bottom part, the internal diameter of described trapezoidal base and outer tube,
The external diameter of inner tube coincide, and concrete grade is identical used by concrete grade and pipeline used by described trapezoidal base,
Described steel bar arrangement：Dispose waling between outer tube butt tube seam, the reinforcing bar for φ 16~18 200, to increase
Add the shearing resistance of armored concrete, prevent armored concrete in inner tube jack-in process and produce crack and displacement.Trapezoidal reinforced concrete
Handwoven cloth puts the@200 of φ 8~10 reinforced mesh, and waling top connects with bar-mat reinforcement to be integrally formed, to increase reinforced concrete
The intensity of soil, shearing resistance, twisting resistance.Then unwrapping wire is measured, the equipment for installing inner tube jacking, treats that strength of reinforced concrete reaches
To after construction bearing capacity, inner tube jacking operation is carried out.
