Description
Technical field:
The utility model relates to geotechnical boring opening arrangement technical field, is specifically related to a kind of drilling orifice pipe bracing means.
Background technology:
In the geotechnical boring engineering, according to the requirement of hole structure, some boring needs to install and the fixed orifice pipe, as hydrogeologic drilling.The method of common installation and fixed orifice pipe is after Completion of Drilling Hole, orifice tube is lowered in the boring, backfilling cement slurries or other coagulums in the annular gap space between orifice tube and the borehole wall, make orifice tube and hole wall gluing be frozen into an integral body, thereby make orifice tube be fixed on the hole wall of geologic body and produce certain consolidation strength.After the fixing end of orifice tube, what have also will check the consolidation strength of orifice tube whether to satisfy the requirement of hole internal pressure by withstand voltage test, be consolidation strength whether greater than liquid or gas in the boring behind the bore closed to the pressure in aperture, visit and discharge water and the part Grouting engineering as hydrogeologic drilling under the coal mine, down-hole.
The consolidation strength of drilling orifice pipe can improve by the length that increases orifice tube, so in most cases the Design of length that needs only orifice tube gets long enough, the consolidation strength of orifice tube can meet the demands fully, makes orifice tube that the interior high-pressure fluid of the force-closed boring of enough energy be arranged.
Along with the extensive use of borehole engineering in production and construction, under some special geological condition, when the length of orifice tube was subjected to the restriction on stratum, the consolidation strength of orifice tube was difficult to meet the demands.The test requirement of engineering that discharges water was fixed orifice tube before boring discloses the aquifer as coal mine, and make the high hydraulic pressure that orifice tube can the confining bed of aquifer, occur in time to withdraw from drilling tool and closing the orifice tube valve behind the boring water burst so that disclose the aquifer, eliminate the harm that the boring water burst causes mine in boring.But the distance between boring tapping and target aquifer is too near, and during the curtailment of formation consolidation orifice tube, the method consolidation strength of the fixed orifice pipe that the above is conventional is limited, is difficult to water under high pressure is enclosed in the boring.
Realize at existing pure dependence annular gap coagulum under the method for solid pipe, solve above-mentionedly, just must use superpower solid tube material or improve solid length of tube by force because of solid length of tube short-range missile causes the problem of orifice tube consolidation strength deficiency.The former involves great expense and does not have ripe superpower solid tube material at present; The latter need disclose the aquifer by force and top water creeps into certain depth, use the glued annular gap of rapid condensation material filling then, a kind of method that has been 200610012916.4 disclosure of the Invention as application number, can have under the situation of water by slip casting chemical material fixed orifice pipe in boring, this method not only needs special chemical material and complicated grouting equipment, also to head on the boring water burst simultaneously and carry out operation, therefore exist solid plumber plant complexity, cost height, problem such as certain risk is arranged.
Summary of the invention:
The purpose of this utility model is that a kind of drilling orifice pipe bracing means will be provided, to solve cost height, the complex process that prior art exists, the problem that certain risk is arranged.
For solving the problem that prior art exists, the technical scheme that the utility model provides is:
A kind of drilling orifice pipe bracing means comprises orifice tube and external piece, and its special character is: be provided with the girth member of band mesopore between orifice tube and external piece, be evenly equipped with the outer hole of connection on the described girth member periphery, fixedly be equipped with anchor pole on the hole outside connecting.
Above-mentioned girth member is the orifice tube flange of an increasing, is evenly equipped with the endoporus that connects external piece on the interior week of this orifice tube flange, is evenly equipped with on the enlarged of periphery to connect outer hole.
Above-mentioned orifice tube flange is directly welded in the orifice tube end.
Above-mentioned girth member comprises orifice tube flange and reinforcing dish, and the diameter of described reinforcing dish is evenly equipped with the endoporus that connects aperture pipe flange and external piece greater than the orifice tube flange on week in the reinforcing dish, is evenly equipped with on the periphery to connect outer hole.
Above-mentioned orifice tube flange is directly welded in the orifice tube end, and the reinforcing dish is connected by bolt with orifice tube flange and external piece.
Above-mentioned external piece is slip casting gland, valve or other orifice members.
Compared with prior art, advantage of the present utility model is as follows: 1, reinforcing mode is simple; 2, consolidation effect is remarkable; 3, processing and fabricating is easy, is convenient to field conduct.
