Detailed Description
The construction and principles of the present utility model will be readily apparent to those skilled in the art from the following description taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The utility model relates to a rapid construction wall protection tool based on a apoplexy crack development rock stratum, which comprises three horizontal steel pipes, three vertical steel pipes and a reinforcing steel bar net sheet.
The horizontal steel pipe adopts a stainless steel square steel pipe with 50mm and 2mm wall thickness as a raw material, and is welded with the vertical steel pipe to form a 'field-shaped' whole. An L-shaped angle steel sheet is welded on the outer wall of one end of the upper and lower horizontal steel pipes and is used for connecting the horizontal steel pipes of the other wall protection tool. And a pore canal of 20mm is reserved at the end head of the other side, so that an expansion bolt can be conveniently driven in during construction. Simultaneously, two straight steel sheets are welded at two quarter points of the lower horizontal steel pipe for connecting the horizontal steel pipe of the other wall protection tool. Holes of 20mm are reserved at two quartering points of the upper horizontal steel pipe, so that expansion bolts can be conveniently driven in during construction operation.
The vertical steel pipe consists of 50 x 2mm square steel pipes. And the two ends of the square steel pipe with the length of 50mm from 50 to 50 are cut off, and a surface with the length of 50mm is left, so that the square steel pipe is convenient to weld with the horizontal steel pipe.
The steel bar net sheet is a net sheet with longitudinal steel bars and transverse steel bars which are respectively arranged at intervals of 100mm and are mutually right-angled, and all the cross points are welded together, and is manufactured by adopting HPB300 hot-rolled polished round steel bars with the diameters of 6 mm. The reinforcing mesh is connected with the horizontal and vertical steel pipes in a welding mode, so that the effect of blocking falling rocks in the holes is achieved.
The dimension of the L-shaped angle steel piece is 50 x 4mm. One side of the expansion bolt is welded with the horizontal steel pipe, and a hole with the width of 20mm is reserved on the other side of the expansion bolt, so that the expansion bolt can be directly driven into the expansion bolt when the expansion bolt is connected with the other horizontal steel pipe during construction. The size of the straight steel sheet is 50 x 100, the upper half 50mm is completely welded with the horizontal steel pipe at the bottom of the upper layer of wall protection tool, and the lower half 50mm is reserved with a hole with the width of 20mm, so that expansion bolts can be directly driven in when the steel sheet is connected with the horizontal steel pipe at the top of the lower layer of wall protection tool during construction.
The wall protection tool is used as follows:
1. before use, the wall protection tool needs to be checked for long-term unused rapid construction. And measuring the positions of the reserved pore canal of the connecting steel sheet and the reserved pore canal of the steel pipe by using a steel ruler, checking whether the deviation occurs, and if the deviation occurs, re-welding, adjusting the positions of the connecting steel sheet, so that smooth connection can be ensured in future construction.
2. When the wall protection construction is carried out, the quick construction wall protection tool is lifted into the hole, a worker below the quick construction wall protection tool is received, the first piece is abutted against the rock wall, the second piece is lifted into the rock wall, the second piece is abutted against the rock wall, and the second piece is abutted against the first piece vertically. At this time, the positions of the reserved holes of the connecting steel sheet and the reserved holes of the steel pipe on the two wall protection tools are required to be aligned.
3. After confirming that the two wall protection tools are aligned to the correct position, an expansion bolt with the length of 20mm is driven in for connection and fixation. The expansion bolts not only play a role in connecting two wall protection tools, but also are driven into the rock wall, and the anchoring length is 10cm. The wall protection tool is firmly connected with the rock wall, and falling is avoided.
4. Repeating the steps 1-3, connecting four dado tools of the first layer, excavating the next section, and connecting the dado tools of the second layer after reaching the corresponding depth. When the second layer and the lower wall protection tools are connected, the lower layer and the upper layer wall protection tools are connected together through the connecting steel sheets. And then repeating the steps 1-3 until the construction of the wind-converted rock stratum retaining wall of the whole hole digging pile is completed.
