The present invention discloses a kind of floating construction method of installation of more PE pipes in large-scale push pipe, it is to dig active well and received well respectively at push pipe both ends, and ramp is dug down to active well reserving hole, the welding of PE pipe is completed outside active well, and drawing head is welded in head end, hoist engine is parked in one end of received well, fixed bracket and pulley blocks are set in received well, manually the wirerope being wrapped on hoist engine is drawn around pulley blocks into received well, and it is successively drawn along push pipe and active well to outside active well using trailer wagon, it is connect with drawing head, and in piece seizing wire of wirerope head end system, water filling reaches certain water level in push pipe, utilize rope traction PE pipe to commitment positions, it draws water, PE pipe is set to sink to predetermined position.Floating construction method of installation of the invention, improves the welding quality of PE pipe, is advanced using rope traction PE pipe, and the tractive resistance of PE pipe is reduced using the buoyancy of water, solves the problems, such as that more PE pipe installations are in place difficult in small space.
Description
Technical field
The invention belongs to technical field of municipal construction, it is specifically a kind of be suitable under wear river, lake, highway, railway
The floating construction method of installation of more PE pipes in the large-scale push pipe that more PE pipes are installed in push pipe.
Background technique
The pipeline engineering that river, lake, highway, railway are worn under currently, generallys use the structure of more PE pipes built in casing
Form.Construction is worn for more PE pipes in casing, can use there are two types of arrangement and method for construction: one is pour in sleeve bottom
Bed course is laid with track, PE pipe is placed on travelling bogie, worn PE pipe in place by the way of traction；Another kind be
Casing surrounding loads onto one group of directive wheel at a certain distance, in place using mode of traction.However, two schemes all Shortcomings it
Place: the first easily occurs derailing and phenomena such as card wheel, and subsequent several PE manage difficulty in place and are gradually increased；Second is that PE pipe is whole
After in place, casing internal orifice space is limited, and the dismounting of directive wheel is more troublesome, and this scheme is only used for the peace of first PE pipe
Dress, the installation for not being suitable for several PE pipes below are in place.
Sewage treatment plant tail water pipeline engineering at present is all made of 3 × DN700PE pipe, housing DN2000 reinforced concrete sleeve
Form, under wear river distance up to 600m, reinforced concrete sleeve uses and wears river bed under push pipe, therefore needs more in a kind of push pipe
Root PE pipe wears construction method to solve the above problems.
Summary of the invention
Of the existing technology in order to solve the problems, such as, the present invention provides a kind of floating installation of more PE pipes in large-scale push pipe
Construction method realizes that the installation of more PE pipes in small space is in place, and the installation for successfully solving more PE pipes in push pipe is in place
Difficult problem.
The present invention adopts the following technical scheme: in large-scale push pipe more PE pipes floating construction method of installation, including it is following
Step:
(1) active well excavating in push pipe head end, received well is excavated in push pipe end, and active well is connected to by push pipe with received well,
Active well has reserving hole far from the side of push pipe, excavates out a gug to reserving hole from natural ground；
(2) PE that the quasi- PE pipe of several feast-brand marks is welded into a required length is managed, and welds drawing head in stem end；It is connecing
It receives and fixed bracket and pulley blocks is manually set in well, hoist engine is arranged in received well exit；
(3) manually the wirerope head end being wrapped on hoist engine is introduced in received well around pulley blocks, it is small using drawing
Wirerope head end is passed through and push pipe and is worn into active well by vehicle, using excavator by steel wire penetrating active well reserving hole to the
Wirerope is manually connect by the stem of a piece PE pipe with drawing head, and in piece seizing wire of wirerope head end system, seizing wire
One end be placed on outside active well；
(4) water filling in push pipe, starts hoist engine, draws first PE pipe and enter in push pipe through active well, after traction in place,
Water in push pipe is taken away, first PE pipe sinks in place；
(5) wirerope is drawn back using excavator dragging seizing wire, is drawn out to the head end of wirerope outside active well, by steel
Cord is connect with the drawing head of second PE pipe；
(6) step (4) and step (5) are repeated, until all PE pipes are respectively mounted in place.
The present invention uses floating method, sufficiently by the buoyancy of water, itself lower amount of deflection is managed using long range PE, along excavation
Gug can smoothly enter into push pipe predetermined position, the installation for completing more PE pipes is in place, and tractive force is greatly reduced；Wirerope with lead
To draw the advance of PE pipe, subsidiary seizing wire, which plays, draws back wirerope for leader connection, in case drawing the mobile effect of lower root PE pipe.
The first open area other than active well of the present invention completes the welding of PE pipe, solves narrow space in push pipe, applies
The problem of work industry inconvenience, PE pipe welding quality are guaranteed；By the way of floating traction, the buoyancy of water is made full use of, is reduced
The resistance of PE pipe traction after PE canal float is in place, without removing associated satellite device, is saved compared with other construction methods
Construction time.The floating construction method of installation technical feasibility of more PE pipes, safe and reliable, economy are closed in large-scale push pipe of the invention
Reason, has a large promotion value.

14 head end of wirerope is passed through into push pipe 10 with trailer wagon and is worn into active well 6, wirerope 14 is passed through into work using excavator 2
Make the stem of well 6 reserving hole, 5 to the first PE pipes 3, manually connect wirerope 14 with drawing head 11, and is first in wirerope 14
End is a seizing wire 17, and one end of seizing wire 17 is placed on outside active well 6；
(4) into push pipe 10, water filling reaches certain water level 8, starts hoist engine 16, draws first PE using wirerope 14
Pipe 3 enters push pipe 10 through active well 6, before PE pipe 3 enters active well 6, can use excavator 2 and assists PE pipe 3 along descending
Road 4 moves forward, and when PE pipe 3 enters active well 6, can use truck crane 7 and slightly slings PE pipe 3, auxiliary PE pipe 3 enters work
Make in well 6；It is equipped with protective device 9 in the entrance of push pipe 10, PE pipe 3, inevitably can be with the end of push pipe 10 when entering push pipe 10
Wall collides, and the gouging abrasion of push pipe 10 can be preferably minimized by protective device 9；After traction in place, by the water in push pipe 10
It drains, first PE pipe 3 sinks in place；
(5) seizing wire 17 being dragged using excavator 2 and drawing back wirerope 14, the head end of wirerope 14 is made to be drawn out to active well
Outside 6, wirerope 14 is connect with the drawing head 11 of second PE pipe 3；
(6) step (3) and step (4) are repeated, until all PE pipes 3 are respectively mounted in place.
Above-described is only one embodiment of the present invention.It should be pointed out that for those of ordinary skill in the art
For, without departing from the principle of the present invention, several variations and modifications can also be made, these also should be regarded as belonging to this hair
Bright protection scope.
