Preferably, described top portion comprises a metal inductive head and hard top, is provided with a hole for water spraying in the hard top; Push-bench also comprises a feed water pump, and this feed water pump is connected with an end of a water pipe, and the other end of this water pipe pierces into and extend to always described hole for water spraying from auxilliary first end of establishing pipe; One metal induction indicator, this metal induction indicator is connected with an end of a metal induced signal line, and the other end of this metal induced signal line also pierces into from auxilliary first end of establishing pipe, always to assisting second end extension of establishing pipe and being connected with described metal inductive head; One oil hydraulic pump, this oil hydraulic pump is connected with two-way cylinder by the hydraulic pressure fuel supply line.
Preferably, described auxilliary establish Guan Weiyi section homogeneous tube or be in charge of by at least two sections be spliced.
Compared with prior art, advantage of the present utility model: simplicity of design, easy to maintenance, safe and reliable, be fit to the short distance operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
Shown in Fig. 1 is the short distance push-bench, comprising: be arranged on the support of operation well top, it is characterized in that, described support is provided with a vertical adjustable lever and and controls the controlling device (not shown) that this adjustable lever is shifted up and down in operation well; The underpart of this adjustable lever is horizontal a two-way oil cylinder (be used for promoting auxilliary establish pipe be shifted to auxilliary pipe well), the push rod of this two-way cylinder one end is connected with auxilliary first end of establishing pipe by the clamp head, auxilliary second end of establishing pipe is connected with a top portion by adaptor tube, described top portion comprises a metal inductive head and hard top, is provided with a hole for water spraying in the hard top; Push-bench also comprises a feed water pump (connecing external water source), and this feed water pump is connected with an end of a water pipe, and the other end of this water pipe pierces into and extends to described hole for water spraying always from auxilliary first end of establishing pipe, and water can be sprayed from hole for water spraying; One metal induction indicator, for detection of barrier metallization, this metal induction indicator is connected with an end of a metal induced signal line, the other end of this metal induced signal line also pierces into from auxilliary first end of establishing pipe, extend and is connected with described metal inductive head to auxilliary second end of establishing pipe always, this metal is responded to indicator and is connected by the earthing rod that connecting line is inserted in hard surfacing and soft soil layer again; One oil hydraulic pump is furnished with pressure gauge, and this oil hydraulic pump is connected with two-way cylinder by the hydraulic pressure fuel supply line, for two oil pumps provide power.All be arranged on the control box such as above-mentioned pressure gauge, metal induction indicator etc.
Working principle:
At first, push-bench support 4 is installed on push pipe operation well 1 top.Then, two-way cylinder push-bench 2 is put into active well, being configured by adjustable lever 5 needs the auxilliary degree of depth and direction of establishing pipe 16, more required assisting is established pipe according to every auxilliary length of establishing pipeline of size decision of operation well, generally is operation well width 2/3rds.Hard drill bit 13 usefulness silk mouthful ways of connecting is installed in the auxilliary head last 20 of establishing pipe, be enclosed within auxilliary establishing on the head that is placed in the two-way cylinder push-bench on the pipeline with clamp head 3, water pipe 11 and induced signal line 10 are through auxilliary establishing in the pipe 16 and are extracted by the back, water pipe is connected on the feed water pump 12, metal induced signal line 10 is connected on the metal induction indicator 9 of control box, to two-way cylinder push-bench 2 fuel feeding the auxilliary pipe 16 of establishing is pushed ahead by hydraulic pressure fuel supply line 7 by oil hydraulic pump 6 after being ready to complete above-mentioned work, in soft soil layer 19 advances.
If soil property hardness evenly observes the normal operating pressure 8 of oil hydraulic pump linearly increase, generally do not need the water spray construction, if running into hard obstacle hydraulic gage 8 during pipeline advances can raise suddenly, confirming as the place ahead when pressure rising suddenly has the hard obstacle to adopt high pressure water injection then, forwards sprayed water to an anti-blocking hole of spraying water with high pressure by water pipe 11 by raw water service pump 12, wash the soil of hard obstacle periphery open or make the soft soil layer 19 soft obstacles that make produce displacement, make the auxilliary pipe 16 of establishing continue to advance auxilliary according to direction initialization and establish during pipeline advances.
Over the ground reach into galvanic circle through metal indicator 9 through ground stud 22 by metal induced signal line by metal inductive head 14 if run into metallic conduit, reflect at metal indicator 9, proof the place ahead has the metal object pipeline can not advance, must redefine the auxilliary degree of depth of establishing pipeline 16 to avoid the metal obstacle, avoid causing the accident.In whole push pipe operation, can adopt the supplementary equipment metal detector to purchase auxilliary direction and the degree of depth of establishing pipe of observation separately, arrive the auxilliary pipe well 17 in accurate position to guarantee the auxilliary pipe 16 of establishing.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
