Abstract
The present invention relates to an installation consisting of drilling system, guide system, propulsion system, clamping system and control system which are connected in turn. This installation can directly utilize through pipeline to track designed curve and drill so as to cut through river instead of complex traditional process of drilling hole with drilling rod, repeatedly expanding hole and making pipeline cut through river, and can use one-step operation to cut through river.
Description
The present invention relates to a kind of direct of buried pipeline construction and follow the tracks of the device that rivers are passed through in design curve boring, belong to pipeline crossing construction technical field with connecting pipeline.
At present the device of buried pipeline crossing construction technical field is more, technology comparatively advanced my advance machine as push pipe, the RB-5 type is large-scale, medium-sized directed bore etc. of RB-3 type.
My advance machine push pipe, and most equipment is introduced from Japan, and the crossing construction major part is to advance the big caliber of people's operation in the pipe.My advance machine by hydraulic jack jacking forward.The ground that bores adds water to be pulverized in the machinery head, establishes pipeline with pump in crossing pipeline and is discharged to ground.Inject mud lubrication between crossing pipeline and the soil, the construction period is long, operating expenses is high.
Miniature push pipe, distance exist problem long in time limit, that expense is high, distance is short within 100M-200M.The medium-sized directed major part of boring of the large-scale and RB-3 type of RB-5 type is the equipment of introducing from the U.S..It is as drilling power with MTR.Direction is by the control that realizes in the drill bit back leading of a drilling rod that curves 1.5 ° of fixed bend.During construction earlier one by one stacks bore the pilot hole opposite bank of crossing the river, connect on the opposite bank and draw together the hole device, rig returns and drags one on drilling rod to unload down when drawing together the hole, stacks draws drawing together on the device of hole one by one from the opposite bank.Draw together hole 4-6 inch at every turn.Draw together hole several times when caliber is big repeatedly, confirming when drawing together last hole not have could return when collapsing the hole drags crossing pipeline to cross the river, as occurring the hole of collapsing midway returning to drag, return and drag the motionless bit freezing that causes, have only drilling rod and pipeline are lost in the riverbed soil layer together, risk is bigger, can not pass through to contain part cobble and coarse sand stratum.Because mud does not return anti-flow velocity when drawing together the hole, draw together the cobble that gets off and coarse sand and be scattered in to pile up when going back to the hauling pipe road in the hole and cause bit freezing." large-scale directed the boring of RB-5, the peace maximum is crept into length and can be reached 1KM, and the diameter that buries the pipeline maximum can reach φ 1M.This equipment is doted on greatly very much, and the 170T that weighs certainly shifts one and costs more than 1,000,000 yuan, and floor space is big, so its application area is subjected to the restriction of above several indexs ".Select from " Yu Binquan, Chen Chuancan write: the pipe jacking construction technique of People's Transportation Press's distribution ".
