Background technique
In recent years, since the aggravation of mankind's activity and extreme natural weather situation, many slope instabilities cause huge
Economic loss and casualties event.Wherein, rainwater, underground water infiltrate, and river level rise is one for causing slope instability
Major reason.Currently used side slope protection technology has friction pile supporting, suspension roof support, drainage system etc..For most of sides
Slope, drainage system are highly effective and economical rationality administration ways.Many side slopes are also in the base using other administration ways
Drainage pipeline project construction is carried out on plinth.Surface water in side slope can be drained by building the modes such as gutter, for side
Underground water in slope is then needed using modes such as drainpipes with lowering of watertable.
However, the drainpipe in side slope is often blocked with reasons such as the postponements and construction of time, blocking draining
The substance of pipe is mainly the thinner mud of particle and clay, and water penetration is poor but fragile, and underground water cannot be smoothly from draining
Smooth discharge in pipe.Rainfall or surrounding underground water, which infiltrate, is lifted slope underground water position, and the soil body generates water pressure on the downside of side slope
To increase sliding force, also, underground water can have an impact the physico-mechanical properties of Rock And Soil, or even cause weak sliding
Face can cause extreme influence for the stability of side slope.
Currently, usually punching pipe laying again for the administration way for blocking drainpipe, that is, blocking slope drainage pipe
Position is punched with drilling machine again, and original drainpipe is destroyed completely, then buries drainpipe again again with punch position.This side
Method needs biggish manpower and economic cost, because other reasons are no longer administered, it is hidden even to generate biggish safety for some side slopes
Suffer from.In terms of existing desilting equipment and dredging method are also applicable only to the urban construction such as sewer, it is not involved with side slope
Drainpipe harnessing project.Therefore, a kind of economic and effective side slope Accrete clearing device is needed at present, to having blocked slope drainage pipe
Carrying out dredging improvement makes it play a role again.

Canal ponding or water storage of digging pit extraction etc., the main function at water source is that bit location in drainpipe is depressed by water pump, by drill bit
The chopping soil body is taken out of and uses current scour drainpipe side wall residual sludge；Water pump 1 is small portable water pump, is connected with drilling machine front
It connects, water source can be extracted and give pressure and will have the water of pressure to be transmitted in drilling rod, pressure water is full of drilling rod, because drill pipe diameter is only
For 1cm, water flow is very fast, reaches bit location by direct circulation mode, and the cutting different angle using pressure itself and flow velocity
The silt soil that native knife is smashed flows out around drill bit and drilling rod.It should be noted that since the drainpipe in side slope buries angle
Smaller, buried depth is about tens of rice to tens meters, therefore small pump is only needed to provide relatively small pressure, be enough by
Drill bit smashes mud and goes out bit location and flow out along drainpipe from drainpipe and drilling rod gap, reaches borehole cleaning purpose, this pressure
It will not cause the destruction of slope drainage pipe.
In addition, referring to Fig. 8, drainpipe 11 is embedded in side slope lower parts at different levels with 5-10 ° of angle of declination when slope controlling 10,
Effectively dredging drainpipe mud, guarantee drainage effect it can enhance slope stability.
When the utility model is used, it is to be blocked in slope drainage pipe by mud, after cannot effectively draining, this set facility is transported
Drill bit assembly is connect with drill rod assemblies then, is put into drainpipe first on deck by equipment to scene, will constantly be bored
Bar and drill bit go deep into drainpipe and continue jointed rod, and drilling rod is connected drilling machine after the position of drill bit reaches blocking region；With
Starting drilling machine rotates drill bit with drilling rod after water pump extracts water source and the water for having pressure is pumped into drilling rod, and then bit cutting is made to become silted up
Mud and shaking drilling machine cuts it sufficiently, then visible muddy water flow is mingled with mud and flows out from slope drainage nozzle.Such section is bored
Among bar all deeply drills, but dredging drainpipe not yet, drilling can be suspended, switched off the pump, after dismounting drilling rod and drilling machine part
After continuation jointed rod reaches designated length, connection drilling machine opens water pump and continues to creep into, until the silt in clear completely root drainpipe
Mud reaches dredging purpose.
For the utility model when carrying out drainpipe dredging, by taking a certain slope drainage pipe as an example, specifically used method is as follows:
1. the side slope of pair embedding drainpipe is checked, the drainpipe that may be blocked is found out.According to construction information, understanding will
The information such as caliber, buried depth, the form of construction work of dredging drainpipe investigate water source distribution on or near side slope.According to the above money
Material prepares bit size and quantity, prepares drilling rod model and length, prepares water source etc., carries out preliminary preparation.
2. site layout project instrument, pump power is in place, suitable dimension drill bit is connect with first segment drilling rod and along oblique upper
It is put into drainpipe, continues jointed rod during drill bit gos deep into drainpipe, such as reaches blocking position, in place conditions permit
In the case where access several meters of drilling rods again, connect drilling machine.
3. pressure water enters drilling rod after starting water pump, drilling machine is opened immediately, and rotation drilling rod starts to creep into dredging, bores in operation
One side drilling depth when machine, it is pico- on one side to shake drilling machine, the mud in water pipe is all shredded, then i.e. visible sewage is from drainpipe pipe
Mouth outflow.
4. drilling machine leading edge closes drilling machine and water pump when will reach drainpipe nozzle, temporarily when drilling rod and drill bit continue deeper into
Stop drilling machine, rig down and drilling rod junctions, continue to connect next section drilling rod, then connect drilling machine, start water pump and drilling machine after
Continuous drilling dredging, until drainpipe buried depth when drill bit reaches construction, stops drilling, this drainpipe dredging work is completed.
5. the device is placed at next blocking position of drain pipe, continues dredging according to the above operating procedure, such as drain
Pipe caliber change then needs to consider whether more bit change.
6. completing dredging, provision for disengagement.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
