Abstract
Provided is a pressure-spraying-type deslagging method. A movable retaining cylinder 6 is added to the upper portion of an original retaining cylinder 5. A deslagging port 3 is formed in the upper portion of the movable retaining cylinder 6, and an original deslagging port 2 is narrowed so that the flow of the original deslagging port 2 is smaller than that of a slurry pump. When the slurry pump 4 constantly pumps slurry into a well, two slurry surfaces with different heights are formed. The lower slurry surface bears pressure produced by the higher slurry surface under the action of gravity. A pipeline 7 is tightly connected with the deslagging port 2 and extends into a position above an iron hammer 1 in the well. Heavy sediments and rocks and the like in the well enter the pipeline and spray upwards out of the well along with the pipe under the action of buoyancy and pressure of the higher slurry surface.
Description
Technical field:
When the present invention relates to repair bridge and railway, beat the Slagoff method of the impactor of pier use.
Background technology:
At present, repair bridge and railway, beat the impactor that pier uses, Piling speed is slow, and efficient is low, and energy consumption is large.Tracing it to its cause is that the impactor employing is the buoyancy method for discharging residue, is exactly the interior silt rock of well etc., impacts into the floatable lighter particle of mud by iron hammer, floats to slag-drip opening and discharges; And heavier particle must be through repeated stock, diminish, lighten can float till.So Piling speed is slow, inefficiency, energy consumption is large.
In sum: spy of the present invention provides a kind of pressure spray formula method for discharging residue.
Be exactly on original casing, add a movable casing, it highly has (1-1.5) rice to get final product.Dwindle former slag-drip opening and make its flow less than the flow of slush pump, sample has just formed two different mud faces of height.The mud face of lower just has been subject to the pressure that the mud of eminence mud face produces under action of gravitation, the size of its pressure is directly proportional with difference in height between the two.The lower slag-drip opening closely links to each other with pipeline, and pipeline stretches into the top (pipeline will have stronger anti-pressure ability) of the inherent iron hammer of well.Heavier particle enters pipeline under buoyancy and the pressure-acting from the mud face of eminence in the well like this, go up with pipe to spray outside the well.Accelerate Piling speed with this, raise the efficiency, reduce energy consumption.
The specific embodiment:
Add a movable casing 6 on casing 5, topmost has slag-drip opening 3, and the slag-drip opening 2 of casing 5 closely links to each other with pipeline 7, and pipeline 7 stretches into the top of the inherent iron hammer 1 of well.When slush pump 4 continuous pump mud enter in the well, because the flow of slag-drip opening 2 is unnecessary through slag-drip opening 3 discharges less than the flow of slush pump, kept thus highland mud face.Iron hammer 1 takes up silt rock etc. and enters pipeline 7 outside slag-drip opening 2 ejection wells when impacting up and down.
Accompanying drawing: Fig. 1 is generalized section.
Claims (3)
1. utilize the height liquid level poor and the pressure that produces makes liquid have certain speed.Can rush heavier particle, and the outer Slagoff method of ejection well.
2. 1 described as requested: the lower slag-drip opening closely links to each other with pipeline, and is movable.Pipeline can be with the degree of depth increase of well to transferring.
3. be convenient working and grouting, casing is divided into up and down two parts, and top is movable.
