Abstract
The utility model discloses a formula can be filled and to be thickeied steel bow member on an empty stomach for tunnel, it can fill thickening steel bow member including formula on an empty stomach, and polylith formula on an empty stomach can be filled thickening steel bow member and is spliced each other and constitute the inside steel bow member in tunnel, the formula can be packed thickening steel bow member and adopted I -shaped structure on an empty stomach, and processing has the hole on intermediate bottom, has the installation screw hole in the processing of the both sides of hole. The purpose of this device is for overcoming the not enough of above -mentioned prior art, let the steel bow member under the prerequisite that satisfies the atress requirement, reducing steel bow member consumptive material as far as to reach cost -effective mesh.
Description
Technical field
This device relates to construction of tunnel field, is specifically related to the liner structure device that a kind of replacement conventional steel bow member being forever arranged on tunnel carrys out supporting tunnel surrounding.
Background technology
Now, along with the progress of construction technology, the technology of section-steel support country rock is gradually improved.But because high-ground stress schist tunnel support structure unbalance stress is remarkable, when causing supporting and protection structure local failure, stressed smaller part position plays self-strength far away, and when selecting steel arch-shelf, the specification of steel arch-shelf can only be selected again according to maximum weighted, thus cause waste economically.
Utility model content
The object of this device is for overcoming above-mentioned the deficiencies in the prior art, allows steel arch-shelf under the prerequisite meeting force request, reduces steel arch-shelf consumptive material as much as possible, thus reaches cost-saving object.
For achieving the above object, the utility model will adopt following material and technical scheme: a kind of open web type for tunnel can be filled can thicken steel arch-shelf, it comprises open web type can fill thickening steel arch-shelf, polylith open web type can be filled and be thickeied the steel arch-shelf that steel arch-shelf is spliced to form tunnel internal mutually, described open web type can be filled and be thickeied steel arch-shelf employing I-shaped structure, central dividing plate is processed with hole, is processed with installation screwed hole in the both sides of hole.
Described open web type can fill thicken steel arch-shelf be subject to pressure from surrounding rock larger time, coordinate at hole place and holes filling part is installed, the diameter of described hole filling member is identical with the internal diameter of hole, holes filling part is welded with two otic placodes, otic placode is processed with a screwed hole, a screwed hole and installation corresponding threaded holes merga pass bolt is fixedly connected with.
Described open web type can fill thicken steel arch-shelf be subject to pressure from surrounding rock larger time, can fill at open web type on the central dividing plate thickening steel arch-shelf and add web thickening piece, web thickening piece center is provided with magnet, magnet and the hole merga pass magnetic that matches is fixedly mounted in hole, the diagonal angle of web thickening piece is processed with No. two screwed holes, web thickening piece closed by No. two bolts and No. two corresponding threaded holes be fixedly mounted on web thickening piece dividing plate on.
The external diameter of described magnet is identical with the internal diameter of hole.
Advantage of the present utility model and beneficial effect are:
1, open web type can be filled and be thickeied steel arch-shelf owing to digging out hole at its web place, reduces the consumptive material of steel arch-shelf.Thus reduce expense needed for engineering.
2, steel arch-shelf structure can install hole filling member to meet supporting requirement according to the difference of the power of country rock applying, thus makes steel arch-shelf each several part play self-strength.
3, by applying in a flexible way to web thickening piece, the engineering accident because early stage brings the prediction deficiency of country rock power or the sudden change of country rock power is avoided.
4, connected mode is simple, by nut or directly utilize magnetic holes filling part and web thickening piece to be assemblied in open web type can to fill and can thicken on steel arch-shelf.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in figures 1 to 6, a kind of open web type for tunnel can be filled can thicken steel arch-shelf, it comprises open web type can fill thickening steel arch-shelf 1, polylith open web type can be filled and be thickeied the steel arch-shelf that steel arch-shelf 1 is spliced to form tunnel internal mutually, described open web type can be filled thickening steel arch-shelf 1 and be adopted I-shaped structure, central dividing plate is processed with hole 101, is processed with in the both sides of hole 101 and screwed hole 102 is installed.
Further, described open web type can fill thicken steel arch-shelf 1 be subject to pressure from surrounding rock larger time, coordinate at hole 101 place and holes filling part 2 is installed, the diameter of described hole filling member 2 is identical with the internal diameter of hole 101, holes filling part 2 is welded with two otic placodes 201, otic placode 201 is processed with a screwed hole 202, screwed hole 202 to be fixedly connected with the installation screwed hole 102 merga pass bolt 4 that matches.
Further, described open web type can fill thicken steel arch-shelf 1 be subject to pressure from surrounding rock larger time, can fill at open web type on the central dividing plate thickening steel arch-shelf 1 and add web thickening piece 3, web thickening piece 3 center is provided with magnet 5, magnet 5 and the hole 101 merga pass magnetic that matches is fixedly mounted in hole 101, the diagonal angle of web thickening piece 3 is processed with No. two screwed holes 6, web thickening piece 3 by No. two bolts 7 to match with No. two screwed holes 6 be fixedly mounted on web thickening piece 3 dividing plate on.
Further, the external diameter of described magnet 5 is identical with the internal diameter of hole 101.
This device construction sequence is as follows:
