Description
Technical Field
The utility model relates to a horizontal directional drill returns the planker, especially relates to a novel double-barrelled reducing is with hole back dragging head of directional drill.
Background
At present, in the directional drilling and crossing engineering of large rivers, the construction mode that a main back-dragging pipe and an optical cable sleeve pass through independently twice is commonly adopted, namely twice guiding holes and reaming and twice back-dragging of the back-dragging pipe. The current specification of SY/T4108-2012' design and construction specification of oil (gas) transportation return dragging pipe and optical cable (silicon core pipe) laid in the same ditch): under the premise of not influencing the directional drilling and crossing of the oil (gas) transmission return dragging pipe and the safety of the optical cable (silicon core pipe), the oil (gas) transmission return dragging pipe and the oil (gas) transmission return dragging pipe can be drilled and crossed together in a directional mode.
The double-pipe reducing same-hole back-dragging head is suitable for back-dragging pipe projects with large-scale crossing, complex geological conditions, limited land acquisition area, short construction period and investment, and compared with the traditional optical cable and back-dragging pipe which are independently crossed twice, the double-pipe same-hole back-dragging technology only carries out once crossing construction, so that the crossing construction cost and the construction period of the optical cable sleeve of the directional drilling are reduced. And secondary drilling and other risks caused by independent crossing of the optical cable can be avoided.

According to the technical scheme, the optical cable sleeve hanging lug and the return planker are integrally formed.
According to the technical scheme, the reinforcing plate is fixedly arranged in the back dragging pipe.
According to the technical scheme, the reinforcing plate and the return planker are vertically arranged.
According to the technical scheme, the front end of the return dragging plate is provided with a return dragging hole.
According to the technical scheme, the back dragging pipe plugging head is divided into two parts which are respectively positioned at two sides of the back dragging plate and are welded and fixed with the back dragging pipe and the back dragging plate.
The beneficial effects obtained by the invention are as follows:
1. the utility model discloses in the construction of dragging is returned with the hole to the double-barrelled reducing of horizontal directional drill owner dragging pipe and optical cable sleeve pipe, it can not hang and drag the optical cable sleeve pipe to have solved the conventional person in charge and returned the planker, and if the scheduling problem that drops probably appears when adopting modes such as ligature, main dragging pipe and optical cable sleeve pipe rigid connection return, the off-normal design has guaranteed that the pulling force is too big can not appear in the optical cable sleeve pipe, the cracked situation of sleeve pipe, use this the utility model discloses return to drag owner simultaneously and return dragging pipe and optical cable sleeve pipe, the project cost is practiced thrift, other risks that the optical cable sleeve pipe is returned alone and is dragged and probably appear have been avoidd, save the project. 2. Simple structure, convenient use and low processing and manufacturing requirements. 3.

Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1, the embodiment provides a novel directional drilling double-pipe reducing co-hole back-dragging head, which includes a back-dragging pipe 1, a back-dragging plate 4 is fixedly connected to the front end portion of the back-dragging pipe 1, and a back-dragging hole is formed in the front end of the back-dragging plate. The rear end of the back dragging plate 4 is inserted into the back dragging pipe, one side of the back dragging plate extends out of the side wall of the back dragging pipe and is connected with an optical cable sleeve hanging lug 2, and the front end of the back dragging pipe 1 is plugged through a back dragging pipe plugging head 3.
In this embodiment, as shown in fig. 3, the optical cable sleeve hanging lug 2 and the return planker 4 are integrally formed, that is, the two are integrated, and during the specific manufacturing, a socket is cut on the return planker along the main axis direction, the return planker 4 and the steel plate of the optical cable sleeve hanging lug 2 are inserted, and then the upper and lower pieces of the steel plate are welded and fixed to the return planker plugging head 3. Fig. 5 is a back dragging pipe plugging head structure, reinforcing rib plates are respectively welded and reinforced at two sides of a steel plate of a back dragging plate 4 in a back dragging pipe 1, and fig. 4 is a steel plate with the thickness of 30mm is welded in the back dragging pipe in a direction perpendicular to the direction of the back dragging plate 4, and the back dragging plate is reinforced and fixed. Fig. 2 is a schematic diagram of the back dragging plate, in which the main back dragging pipe and the optical cable sleeve are respectively connected by welding and U-shaped rings, so as to ensure that two back dragging pipes can be dragged back at the same time.
The utility model discloses can be according to the pipe diameter preparation of dragging back the pipe, the long defeated tub for welding of dragging back of scene is got, and the preparation is convenient, does not have accurate part, uses the material for dragging back pipe and steel sheet, very easily draws materials, can be fine satisfy the processing requirement under the open-air simple environment.
In the horizontal directional drilling crossing construction, most of the optical cable sleeves and the main return dragging pipe are separately dragged back, the main reason is that the optical cable sleeves easily damage an anticorrosive layer of the main return dragging pipe, under the current anticorrosive construction technical condition, photocuring or glass fiber reinforced plastic construction is adopted, the abrasion of the optical cable sleeves to the main return dragging pipe can be effectively prevented, the single guide holes and the return dragging construction of the optical cable sleeves can be reduced by adopting double-pipe reducing same-hole return dragging, the construction period and the cost are saved, and the construction efficiency of the directional drilling is improved.
