Description
Technical field
The utility model relates to instrument, particularly a kind of traction tube.
Background technique
At present, the construction of pipe engineerings such as municipal administration, telecommunications, electric power, coal gas, tap water, heating power in town and country construction, the non-excavation horizontal directional drilling machine of most selections is constructed.Its general construction process is: earlier with non-excavation horizontal directional drill machine drill one horizontal orientation passage, thereby be positioned over the construction of finishing pipeline in the horizontal channel with the various MPP pipes of horizontal directional drill machine travel then.But in this large-scale pipeline construction process, the method for traction MPP pipeline but is close to original, and the method for generally taking is: fill in the traction end of MPP pipeline with one section log, and the one, the shutoff pipe end is in order to avoid foreign material such as mud enter pipeline; The 2nd, increase pipe end intensity in case in the distraction procedure pipeline drawn flat or fracture.At the MPP pipe end place that is plugged with log, after radially punching penetrates wire rope, concentrate traction in the lump to come in some pipelines.This shortcoming that is close to original method of construction is: labor intensity is big; The plugging effect instability; Efficiency of construction is low; The waste timber resources.
The model utility content
The purpose of this utility model is exactly the above-mentioned defective that will overcome prior art; provide a kind of plugging effect good, economize on resources, labor intensity is little, efficiency of construction is high and but repeated multiple times is used traction tube, to satisfy the traction construction needs of non-excavation type MPP protective tube.
For achieving the above object, the traction tube that the utility model provides, comprise outer tube, the blocking sheet, reinforced pipe and punching bolt, the external diameter of wherein said outer tube is identical with trailed MPP pipeline with wall thickness, the internal diameter with described outer tube is identical respectively with the external diameter of described reinforced pipe for the diameter of described blocking sheet, described blocking sheet is fixed together in the inner chamber of described outer tube and with described outer tube, described reinforced pipe is inserted the outer end of described blocking sheet, the external port of described outer tube and reinforced pipe is provided with radial direction through hole respectively mutually together and at distance external port 1/3rd places and 2/3rds places, the axis of 2 described radial direction through hole is mutually orthogonal, described punching bolt is 2, penetrate 2 described radial direction through hole respectively, the two ends of each described punching bolt are stretched out the outer wall of described outer tube respectively and are used nut fastening respectively.
The utility model traction tube, wherein said outer tube and blocking sheet adopt modified polypropene MPP material to make.
The utility model traction tube, the material of wherein said reinforced pipe are steel, and wall thickness is 7～15 millimeters.
The utility model traction tube, the external diameter of wherein said punching bolt are 12～20 millimeters.
The advantage and the good effect of the utility model traction tube are:
1, plugging effect is good, guarantees not leak.
2, labor intensity is little; The efficient that saves time height.
3, economize on resources, easy to maintenance, the life-span is long, but repeated multiple times is used.
The utility model traction tube has satisfied the traction construction needs of non-excavation type MPP protective tube.
Be elaborated with reference to accompanying drawing below in conjunction with embodiment.
Description of drawings
Fig. 1 is the schematic representation of the utility model traction tube.
Embodiment
Describe the embodiment of the utility model traction tube in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the traction tube that the utility model provides, comprise outer tube 1, blocking sheet 2, reinforced pipe 3 and punching bolt 5, the external diameter of its middle external tube 1 is identical with trailed MPP pipeline with wall thickness, the external diameter of the diameter of blocking sheet 2 and reinforced pipe 3 internal diameter with outer tube 1 respectively is identical, and outer tube 1 and blocking sheet 2 adopt modified polypropene MPP material to make.The material of reinforced pipe 3 is a steel, and wall thickness is 7～15 millimeters.Be pulled the big or tractive resistance of external diameter of pipe when excessive if meet, the wall thickness that can strengthen reinforced pipe 3 is to satisfying construction requirement.
Blocking sheet 2 is fixed on the inner end of reinforced pipe 3, reinforced pipe 3 and blocking sheet 2 are inserted an end of outer tube 1, the external port of outer tube 1 and reinforced pipe 3 is provided with radial direction through hole 4 respectively mutually together and at distance external port 1/3rd places and 2/3rds places, the axis of 2 radial direction through hole 4 is mutually orthogonal, punching bolt 5 is 2, external diameter is 12～20 millimeters, can determine according to the external diameter of outer tube 1.Be pulled the big or tractive resistance of external diameter of pipe when excessive if meet, the external diameter that can strengthen punching bolt 5 is to satisfying construction requirement.Punching bolt 5 penetrates 2 radial direction through hole 4 respectively, and the two ends of each punching bolt 5 are stretched out the outer wall of outer tube 1 respectively and used nut 6 fastening respectively.
Use below in conjunction with description of drawings the utility model traction tube.
During use earlier with the other end of the outer tube 1 of traction tube be pulled the MPP pipeline and dock with the welding machine thermofussion welding, and then with wire rope by being around in the reinforced pipe 3 apart from fixing behind the punching bolt at external port 1/3rd places, or be fixed on the two ends of same punching bolt, some velamen traction MPP pipelines can be concentrated and carry out towage.After traction is finished, with outer tube 1 be pulled the MPP pipeline and cut along weld seam, the special-purpose traction tube that still can be used as a traction non-excavation type MPP cable protection pipe uses repeatedly.
