Abstract
The invention provides a kind of underground obstacle processing method for jacking construction, including：Step one：Drilled in push pipe upper horizontal to be onstructed, and cause the hole through the soil body being located between originating active well and receiving active well；Step 2：Draught line is laid in the hole, draw-gear is set in active well is received；Step 3：The metallic plate with pointed tooth is drawn to the soil body by the draw-gear and draught line, is drawn the metallic plate and is moved untill the underground obstacle in the soil body is cut off.The invention provides a kind of underground obstacle processing method for jacking construction, the metallic plate with pointed tooth is dragged in the soil body by draw-gear and draught line, and then realize cutting to underground obstacle, ensure that being normally carried out for follow-up jacking construction, and the method is simple and reliable, with low cost, be easily achieved.
Description
Technical field
The invention belongs to underground space development technical field of construction, a kind of underground obstacle for jacking construction is related generally to
Substance treating method.
Background technology
In jacking construction, when particularly carrying out jacking construction to shallow earthing, if there is tree on the ground of push pipe jacking circuit
Wood, then the root system of trees may invade in push pipe jacking section, formed jacking construction in underground obstacle.Due to push pipe
Machine cannot often cut off tree root, after the cutterhead of push-bench encounters tree root, can slide tree root, and disturbance trees even cause trees to damage
The destruction of bad and ground environment, so in order to ensure being normally carried out for engineering, it usually needs migrate the trees on ground, but this can
The delay significantly of duration can be caused, to engineering using greatly negative effect is brought, can be even difficult to due to ground trees sometimes
Migration, causes cannot implementing for engineering, it is therefore necessary to provide a kind of method for removing underground obstacle.
The content of the invention
It is an object of the invention to provide a kind of underground obstacle processing method for jacking construction, to solve existing skill
Deficiency of the art when jacking construction encounters tree root, it is ensured that the normal construction of engineering.
In order to achieve the above object, the invention provides a kind of underground obstacle processing method for jacking construction, bag
Include：
Step one：Drilled in push pipe upper horizontal to be onstructed, and cause that the hole is run through to be located at and originate active well and reception
The soil body between active well；
Step 2：Draught line is laid in the hole, draw-gear is set in active well is received；
Step 3：The metallic plate with pointed tooth is drawn to the soil body by the draw-gear and draught line, draws institute
Metallic plate is stated to move untill the underground obstacle in the soil body is cut off.
Further, in step one, drilled in push pipe upper horizontal to be onstructed using directional drilling equipment.
Further, in step 2, the draught line is steel strand wires.
Further, in step 3, the metallic plate is steel plate.
Further, in step 3, the pointed tooth on the metallic plate is serrated.
Further, in step 3, the underground obstacle is tree root.
For when pipe-jacking project is constructed, break when other barriers such as root system due to ground trees invade push pipe jacking
Push pipe performance difficulty or situation about cannot implement are caused in face, the invention provides a kind of underground obstacle for jacking construction
Processing method, is dragged the metallic plate with pointed tooth by draw-gear and draught line, and then realize to underground in the soil body
The cutting of barrier, it is ensured that follow-up jacking construction is normally carried out, and the method is simple and reliable, with low cost, be easily achieved.

As shown in figure 1, the embodiment of the invention provides a kind of underground obstacle processing method for jacking construction, wrap
Include：
Step one：In the upper horizontal of push pipe 3 drilling 4 to be onstructed, and so that the hole 4 is run through to be located at originates the He of active well 1
Receive the soil body 9 between active well 2；
Step 2：Draught line is laid in the hole 4, draw-gear is set in active well 2 is received；
Step 3：The metallic plate with pointed tooth is drawn to the soil body 9 by the draw-gear and draught line, draws institute
Metallic plate is stated to move untill the underground obstacle in the soil body 9 is cut off.
In step one, using directional drilling equipment 2 in the upper horizontal of push pipe 3 drilling 4 to be onstructed.
In step 2, the draught line is steel strand wires 5, and the draw-gear is hydraulic traction device 7.
In step 3, the metallic plate is steel plate 8, and the pointed tooth on the metallic plate is serrated, the underground obstacle
Thing is tree root 10.
For when pipe-jacking project is constructed, break when other barriers such as root system due to ground trees invade push pipe jacking
Push pipe performance difficulty or situation about cannot implement are caused in face, the invention provides a kind of underground obstacle for jacking construction
Processing method, is dragged the metallic plate with pointed tooth by draw-gear and draught line, and then realize to underground in the soil body
The cutting of barrier, it is ensured that follow-up jacking construction is normally carried out, and the method is simple and reliable, with low cost, be easily achieved.
The preferred embodiments of the present invention are above are only, any restriction effect is not played to the present invention.Belonging to any
Those skilled in the art, not departing from the range of technical scheme, to the invention discloses technical scheme and
Technology contents make the variation such as any type of equivalent or modification, belong to the content without departing from technical scheme, still
Belong within protection scope of the present invention.
