Embodiment
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below by embodiment it is required use it is attached
Figure is briefly described, it should be apparent that, drawings in the following description are some embodiments of the present invention, common for this area
For technical staff, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Referring to Fig. 1 to Fig. 4, the embodiments of the invention provide a kind of compound plastic film precast concrete pipeline 100, including from
The waterproof outer layer 11 that sets gradually outside to inside, braiding casing play 12, concrete main body layer 13, set on the inwall of waterproof outer layer 11
The outer layer extension projection 111 of some internally projections is put, the outer layer extension projection 111 extends to the interior of concrete main body layer 13
Portion, the braiding casing play 12 is the skeleton being knitted to form anyhow, and the braiding casing play 12 is embedded in concrete main body layer
13 inside, some tensioning reserved through hole 131, tensioning reserved through hole 131 edge are also set inside concrete main body layer 13
The length direction for compound pipeline complex pipeline 100 is set, in the inwall of the concrete main body layer 13 at the both ends open of compound pipeline complex pipeline 100
On also open up mounting groove 132, the mounting groove 132 is the groove extended to the inside of concrete main body layer 13, the depth of mounting groove 132
Degree is more than thickness of the tensioning reserved through hole 131 apart from the inwall of concrete main body layer 13, reserved logical will be tensioned by mounting groove 132
Hole 131 is divided into two sections.
When compound pipeline complex pipeline 100 is installed, the front and back end portses of two adjacent compound pipeline complex pipelines 100 are alignd, corresponding two
The tensioning reserved through hole 131 of pipeline is also alignd, and penetrates the tensioning of two adjacent pipelines successively using a connecting rod or screw rod
Reserved through hole 131, you can be relatively fixed two adjacent pipelines, also, this fixed form has two kinds, first, Ke Yixuan
Penetrated, two pipelines connected, second with tensioning reserved through hole 131 of the longer connecting rod 542 along two pipelines,
Tensioning reserved through hole 131 of the two adjacent pipelines at port can be penetrated from a shorter screw rod, screw rod
Termination is exposed out of mounting groove 132, is then tightened using nut, and now mounting groove 132 acts not only as the side of fastening screw
Convenient to operate groove, the usage amount of longer connecting rod can also be saved, reduces cost.
