Abstract
The utility model relates to a welding seam connecting device for a compressible structure of a curved surface arc board type well wall, wherein the compressible structure of the curved surface arc board type well wall of the utility model is used in a structure of a well wall of a vertical well of a mine with a thick surface soil layer, the connecting device for vertical welding seams of arc boards of the utility model is used for the connection of the vertical welding seams of the compressible arc boards in the compressible structure of the arc board type well wall, and telescopic connecting pieces of an arc board with a semicircular section are arranged between connecting seams of two adjacent outer curved surface arc boards and adjacent inner curved surface arc boards, and the two adjacent outer curved surface arc boards are connected with the adjacent inner curved surface arc boards by using the method of weld. As a result, the welding seams are prevented from being pulled apart, and the safety of the compressible well wall is ensured.
Description
One, technical field
But the utility model relates to the weld seam linkage of the board-like borehole wall shrinking structure of a kind of curved surface arc, but the board-like borehole wall shrinking structure of curved surface arc is mainly used in the mine vertical shaft wall structure than thick alluvium, but the vertical weld seam linkage of its arc plate is the connection that is used for the vertical weld seam of the compressible arc plate of the board-like borehole wall shrinking structure of arc.
Two, background technology
In recent years, the big village of China East China, Xuzhou, the Huaibei and mining area, Yanzhou have a lot of pit shafts that the shaft wall fracture accident takes place in succession, had a strong impact on the safety of coal production, and threaten the safety of mine, also brought enormous economic loss thus, the vertical compressible shaft wall structure that begins one's study novel thus.But but on February 12nd, 2000 authorized the board-like borehole wall compression apparatus of curved surface arc (patent No.: ZL99 2 28306.X) of utility model patent by State Intellectual Property Office disclosed a kind of novel borehole wall compression apparatus, but the board-like borehole wall compression apparatus of several curved surface arcs is installed in the topsoil pit shaft segmentation of vertical, when borehole wall vertical stress allows vertical load greater than borehole wall design, but compression apparatus will produce vertical compressive strain, discharge the excessive vertical force of the borehole wall, make the vertical stress of the borehole wall be no more than the allowable stress of design, prevent borehole wall generation break accident.This patented technology is in implementation process, when compressible arc plate under the effect of borehole wall vertical force, when the surrender large deformation appears in pressurized, arc plate level hoop produces stretcher strain, because the stretcher strain performance of steel plate is than low with the thin plate of material, cause the interior hoop tensile stress of arc plate bigger, the vertical weld seam of arc plate takes place sometimes by the phenomenon of drawing crack.
Three, technology contents
1, goal of the invention
The purpose of this utility model is exactly for addressing the above problem, but designed the weld seam linkage of the board-like borehole wall shrinking structure of a kind of curved surface arc, utilize this constructional device when being subjected to horizontal hoop tension, himself structure can produce the characteristics of hoop large deformation, thereby but the horizontal loops that discharges arc plate in the board-like borehole wall compression apparatus of curved surface arc avoids the vertical weld seam of arc plate to ftracture to tensile stress.
2, technical scheme
But the weld seam linkage of the board-like borehole wall shrinking structure of a kind of curved surface arc of the present utility model, but the board-like borehole wall shrinking structure of curved surface arc is by last, the lower limit bearing beam, the arc gusset, positive camber arc plate, negative camber arc plate and last, lower flange is formed, negative camber arc plate and positive camber arc plate are annular, it is a curved surface vertically, curved surface is protruding in all outside pit shaft, negative camber arc plate and positive camber arc plate and last, lower flange is non-perpendicular to weld together, form curved surface arc plate enclosed cavity loop configuration, in its closed cavity, radially evenly arranged many to the arc gusset and on, the lower limit bearing beam, arc gusset position vertical curve panel, more than, the lower limit bearing beam is a symmetry, with last, the lower flange welding, on, under be limited to the bearing beam radial arrangement, be welded on respectively, on the lower flange, in the maintenance, the lower limit bearing beam is in same vertical plane, structural couplings all is placed between adjacent two blocks of positive camber arc plates and the adjacent negative camber arc plate connection seam by the scalable connector of arc plate of semicircle section, adopts the method for welding that adjacent two blocks of positive camber arc plates and adjacent negative camber arc plate are coupled together.
3. technique effect
But adopt the weld seam linkage of the board-like borehole wall shrinking structure of a kind of curved surface arc of the present utility model, but adjacent two blocks of arc plates of the board-like borehole wall shrinking structure of curved surface arc are coupled together, be welded into integral body again, when the compressive strain of arc plate, the hoop tensile stress is bigger, this constructional device can produce bigger stretcher strain under the effect of tensile stress, discharge the hoop tensile stress in the arc plate fully, the hoop tensile stress of the vertical weld seam of arc plate is reduced, thereby can prevent weld seam by drawing crack, guarantee the safety of compressible shaft wall.
