Abstract
The utility model relates to a plugging device for high-precision radial drill holes inside a rock-plug blasting cave, and belongs to the field of construction of water conservancy and hydropower geotechnical engineering. A pulp guide plug is connected with a guide pipe in a sliding mode, a tracking rod is in threaded connection with the pulp guide plug, a sealing head is fixedly connected with the rear end of the guide pipe, the tracking rod is connected with the sealing head in a sliding mode, and a reserved opening is formed in the rear portion of the guide pipe. The plugging device for the high-precision radial drill holes inside the rock-plug blasting cave has the advantages of being novel, simple and unique in structure, high in precision, good in quality, high in practicability, easy to manufacture, easy and convenient to operate, safe, reliable and the like.
Description
Technical field
The utility model belongs to water conservancy and hydropower geotechnical engineering construction field.
Background technology
All kinds of reservoirs that build up in early days in each great rivers basin of China are existence in various degree alluvial hidden danger all, and some big-and-middle-sized reservoir sedimentation problem is very serious.Adopt tunnel, bottom of the reservior sand discharge to succeed and be identified and solve the most effective preferred option of reservoir sedimentation problem.
Dig a sand discharge tunnel by designing requirement in the rock mass of reservoir bank, the bottom of the reservior rock of sand discharge hole inducer is reserved the funnel-form rock mass, be called the rock plug, blow the rock plug with blasting method again, be called chock blasting, tunnel and reservoir are connected, thereby in storehouse, deposit drain into current the sand discharge desilting that downstream river course is realized reservoir.
Chock blasting is a special engineering that technical difficulty is high, construction risk is large, except must grasp regimen and deposit proterties in storehouse comprehensively, also must reconnoitre in detail rock plug surface state, rock plug entity scale and physical-mechanical properties of rock thereof.Some prospectings boring is arranged on rock cock body surface that for this reason need to be at the bottom of the sand discharge hole, i.e. radiating aperture, with the various parameters of rock plug of investigating thoroughly that explosion institute must grasp.Due to concerning the success or failure of whole chock blasting engineering, so design the radiating aperture construction quality, as boring positioning precision, axis direction and straightness accuracy, sealing quality etc., require very strict.
The chock blasting construction requires very harshness to integrality and the permeability rate of rock cock body rock, must carry out strict full hole shutoff to rock plug radiation boring for this reason.Usually designing requirement plugging material and borehole wall knot are firm, and the indexs such as concretion body strength and permeability are consistent with rock plug rock mass, avoid because radiating aperture shutoff quality problems cause the chock blasting project failure.
Summary of the invention
The utility model provides high accuracy radiation borehole sealing device in a kind of chock blasting hole, to solve the not high problem of current radiation borehole sealing device precision.
The technical scheme that the utility model is taked is: lead the slurry plug and be slidably connected with guide pipe, tracking pole is threaded with leading the slurry plug, and seal head is fixedly connected with the guide pipe rear end, and tracking pole and seal head are slidably connected, and there is outfall at the guide pipe rear portion.
The utility model has the advantages that novel structure, the distinguishing feature such as simple, that structure is unique, precision is high, quality is good, practical, be easy to manufacture, easy and simple to handle, safe and reliable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Lead slurry plug 1 and be slidably connected with guide pipe 2, tracking pole 3 is threaded with leading the slurry plug, and seal head 4 is fixedly connected with the guide pipe rear end, and tracking pole and seal head are slidably connected, and there is reserved opening 5 at the guide pipe rear portion.
Claims (1)
1. high accuracy radiation borehole sealing device in a chock blasting hole, it is characterized in that: lead the slurry plug and be slidably connected with guide pipe, tracking pole is threaded with leading the slurry plug, and seal head is fixedly connected with the guide pipe rear end, tracking pole and seal head are slidably connected, and there is reserved opening at the guide pipe rear portion.
