Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
In the description of the present invention, term " transverse direction ", " longitudinal direction ", " on ", " under ", "front", "rear", "left", "right", " perpendicular
Directly ", the orientation of the instructions such as " level ", " top ", " bottom ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position
Relation is put, is for only for ease of and is described of the invention and simplify description, is not that device or the element of instruction or hint meaning are necessary
With specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
As shown in figs 1-9, the present invention provides the device reeved in a kind of HDPE casings, including：Draught line 1 is
It is flexible and deformable；Tow ball 2 is rotatably provided in the HDPE casings, the tow ball 2 and the one of draught line 1
The dismountable connection in end, 1 other end of draught line connect steel wire rope to be connected；Tractor 3, it is moveable positioned at described
Under HDPE casings, the HDPE casings are jacked up.One end of draught line 1 is connected with tow ball 2, it is necessary to can put on simultaneously
Tow ball 2 is inserted certain distance in HDPE casings by several tow balls 2, and draught line 1 is penetrated before direction is, at 2 rear of tow ball
HDPE casings are lifted, and tractor 3 is placed below HDPE casings, tractor 3 is walked forward, drives tow ball 2 in gravity
The lower more front that can enter HDPE casings of effect, until tow ball 2 is pierced by HDPE casings with one end of draught line 1, at this point,
The other end of draught line 1 with steel wire rope to be connected is connected, draught line 1 is pulled to drive the steel wire penetrating HDPE casings.
As draught line 1, it is necessary to which very soft, the frictional force generated when so wearing draught line 1 in super HDPE casings is just unlikely to hinder
Iron ball rolls；But in order to smoothly pull steel wire rope, used draught line 1 must have enough intensity, when guarantee pulls
It will not be broken.After being put into running gear below HDPE casings, running gear, and moment are slowly promoted along HDPE casings direction
