Abstract

The invention discloses a minimally-invasive non-excavation pipe jacking and pull technology which comprises the following steps that 1, a working well and a receiving well are excavated; 2, minimally-invasive non-excavation drilling equipment is erected in the working well, and a hole is drilled towards the receiving well by a guide drilling bit till the drilling bit penetrates into the receiving well; 3, the guide drilling bit of the minimally-invasive non-excavation drilling equipment is dismounted, a back dragging reamer in a preset specification is mounted on a drilling rod of the minimally-invasive non-excavation drilling equipment, the minimally-invasive non-excavation drilling equipment is started for back dragging, and back dragging reaming begins till the back dragging reamer reams and is moved to the working well; and 4: (1), the back dragging reamer is dismounted, the minimally-invasive non-excavation drilling equipment is started, and the drilling rod passes through to the receiving well; (2), a pipe jacking machine is arranged in the receiving well; (3), a cement pipe is put into the receiving well, the drilling rod is sleeved with the cement pipe in a penetrating manner, and a pipe dragging device is mounted; and (4), the minimally-invasive non-excavation drilling equipment is started for the back dragging, the cement pipe is dragged by the pipe dragging device, and the pipe jacking machine is started and jacks the cement pipe into the hole till the cement pipe is dragged and jacked to a preset position.

Description

The non-excavation of a kind of Wicresoft top tube-pulling craft

Technical field

The present invention relates to a kind of construction process of the non-excavation of Wicresoft top tube-pulling craft that is, especially a kind of arm small-caliber pipeline laying process that is applicable in the dirty shunting of rain engineering.

Background technique

Present urban construction, use pipe-jacking technology in the dirty pipework of rain, the technique comparative maturity, but can only do the pipeline of Large Diameter Pipeline, can't resolve the construction of arm pipe with small pipe diameter.The engineering of pipe with small pipe diameter such as 400mm caliber can only adopt road surface excavation pipe laying technology at present, but this technology is destroyed road surface, causes a large amount of dust, has destroyed surrounding environment, and has affected traffic, causes crowded big city more to block up.After having buried, also want road surface to repair, greatly improved cost, and affected the people's livelihood.

Summary of the invention

In order to solve the problems of the technologies described above, the object of the present invention is to provide the non-excavation of a kind of Wicresoft top tube-pulling craft, be used for laying the less pipeline of caliber, road pavement is destroyed little, and efficiency of construction is high.

Complete skill scheme of the present invention is: the non-excavation of a kind of Wicresoft top tube-pulling craft, it is characterized in that, and comprise the following steps:

Step 1, dig active well and received well.Dig respectively an active well and a received well in the two ends, highway section of need tubing, after digging, with channel-section steel, active well and received well are reinforced.

Step 2, make pilot hole.At first the non-excavation rig of Wicresoft is set up in active well, and fixing, then start the non-excavation rig of Wicresoft, utilize starter to the boring of received well direction, until drill bit penetrates received well.

Step 3, borehole enlargement by drawing back.At first pull down the starter of the non-excavation rig of Wicresoft, and install the borehole enlargement by drawing back device of predetermined dimension on its drilling rod; Then start the non-excavation rig of Wicresoft and return and drag, start back the holder reaming, till the reaming of borehole enlargement by drawing back device moves to active well.

Step 4, cement pipe is drawn on top.(1) remove back to and drag reamer, start the non-excavation rig of Wicresoft, drilling rod is crossing to received well; (2) push-bench is set in received well; (3) make cement pipe is put into received well, cover is put on drilling rod and the hauling pipe device is installed; (4) the non-excavation rig of startup Wicresoft returns and drags, and utilizes the hauling pipe device to drag cement pipe, starts simultaneously push-bench, cement pipe is headed in hole, until drag cement pipe top to precalculated position.

The present invention compared with prior art has following beneficial effect:

The invention provides the non-excavation of a kind of Wicresoft top tube-pulling craft, the arm small-caliber pipeline that is applicable in the dirty shunting of the less rain of caliber engineering is laid, compared to excavation pipe laying technology, construction cost reduces greatly, because the destruction of road pavement is less, be unlikely to cause congestion in road, can not affect normally current and life of resident.

Embodiment

Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, in this illustrative examples of the present invention and explanation, be used for explaining the present invention, but not as a limitation of the invention.

The present embodiment provides the non-excavation of a kind of Wicresoft top tube-pulling craft, and its workflow as Figure 1-3, comprises the following steps:

Step 1, dig active well 1 and received well 2.Dig respectively an active well 1 and a received well 2 in the two ends, highway section of need tubing, after digging, with channel-section steel, active well 1 and received well 2 are reinforced.

Step 2, make pilot hole.As Fig. 1, at first the non-excavation rig 3 of Wicresoft is set up in active well, and fixing, then start the non-excavation rig 3 of Wicresoft, utilize starter to received well 2 direction borings, until drill bit penetrates received well 2.

Step 3, borehole enlargement by drawing back., as Fig. 2, at first pull down the starter of the non-excavation rig 3 of Wicresoft, and install the borehole enlargement by drawing back device 5 of predetermined dimension on its drilling rod 4; Then start the non-excavation rig of Wicresoft and drag for 3 times, start back the holder reaming, till 5 reamings of borehole enlargement by drawing back device move to active well.

Step 4, cement pipe is drawn on top.As Fig. 3, (1) removes back to and drags reamer 5, starts the non-excavation rig 3 of Wicresoft, and drilling rod 4 is crossing to received well 2; (2) push-bench 6 is set in received well 2; (3) cement pipe 7 is put into received well, cover is put on drilling rod 4 and hauling pipe device 8 is installed; (4) start the non-excavation rig of Wicresoft and drag for 3 times, utilize hauling pipe device 8 to drag cement pipe 7, start simultaneously push-bench 6, cement pipe 7 is headed in hole, until drag cement pipe 7 top to precalculated position.

The above technological scheme that the embodiment of the present invention is provided is described in detail, applied specific case herein principle and the mode of execution of the embodiment of the present invention are set forth, above embodiment's explanation is only applicable to help to understand the principle of the embodiment of the present invention; Simultaneously,, for one of ordinary skill in the art,, according to the embodiment of the present invention, all will change on embodiment and application area, in sum, this description should not be construed as limitation of the present invention.
