Technical field
The utility model relates to a kind of well cementing device, is specifically related to a kind of carbonate rock and the boring of ragstone underground pipe and provisions for grouting.
Background technology
For a long time, there is long, the problem such as cost is higher of pore-forming difficulty, cycle in ground source heat pump central air-conditioning system construction ground pipe laying in the carbonate rock of complex geologic conditions and hard rock stratum.The traditional pore-forming technique in carbonate rock and hard rock area be machinery widely different turn to creep into get core pore-forming, its shortcoming is that rate of penetration is slow, work efficiency is low, meets solution cavity crack and groundwater treatment difficulty and backfill difficult quality guarantee etc.Therefore, there is limitation to a certain degree in the application in carbonate rock and hard rock area in ground source heat pump central air-conditioning system, needs the problem solving in carbonate rock and the boring of ragstone underground pipe and grouting badly.
Summary of the invention
The purpose of this utility model is, for solving the technical problem such as pore-forming difficulty, backfill difficult quality guarantee that in carbonate rock and hard rock stratum, construction ground pipe laying exists, a kind of carbonate rock and ragstone underground pipe drilling equipment are provided, and the corresponding Underwater Pressure for such boring grouting backfilling apparatus.
The technical solution of the utility model is mainly made up of the pneumatic pore-forming drilling equipment of air and the Underwater Pressure grouting backfilling apparatus of carbonate rock and ragstone underground pipe.
The pneumatic drilling process of air is using air as the power of broken rock facility and doubles as a kind of drilling method of scouring media.Be characterized in soon, not needing to get core, high efficiency for ragstone rate of penetration.It comprises at least one air compressor machine, this air compressor machine flows to drill bit by ground airduct, standpipe, flexible pipe by high pressure draught, between air compressor machine and ground airduct, be provided with venting valve, be used for controlling air-flow, simultaneously, at the other instrument board that arranges of ground airduct, be combined to regulate for observation with venting valve and control air pressure.Wherein, flexible pipe is snakelike coiling setting, and flexible pipe one end connects standpipe, and the other end connects a water tap, and is connected with rig, for controlling air-flow and current enter drill bit.Pithead position in rig and hole arranges wellhead assembly, creeps into posture for fixing rig and adjustment rig.In hole, side opening arranges a backwind tube, and backwind tube connects a deduster, for reducing dust in hole.
In addition, corresponding with drilling equipment, the utility model also combines such Underwater Pressure grouting backfilling apparatus, and it is by the bottom of hand-hole under grout pipe is together with heat exchanger PE pipe, at the bottom of heat exchanger PE pipe adopts double u-tube chi structure to sink to hole, grout pipe stretch at the bottom of hole near heat exchanger PE pipe in basement rock.Then adopt the full hole disposable cement injection mortar backfill of certain pressure (1 ~ 3MPa).Be characterized in that installation speed is fast, grouting quality easily ensures.
Technique effect of the present utility model: adopt this construction technology to efficiently solve the problems such as and backfill grouting quality difficult control high at carbonate rock and construction ground, hard rock stratum pipe laying pore-forming difficulty, cost, greatly reduce expense and shortened the cycle, for positive impetus is played in the application of carrying out shallow layer geothermal energy in carbonate rock and hard rock area.
