Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to an auxiliary pipe jacking support safety protection device. Background Art

[0002] Pipeline construction in new construction and reconstruction of urban roads mostly adopts pipe jacking technology. In the pipe jacking construction of deep square working shafts, the support of the foundation pit is mostly completed by steel sheet pile cofferdam. In order to avoid geological collapse and water seepage during construction, square steel sheet pile enclosures will be added, that is, horizontal partition steel sheet piles are set around the steel sheet piles to play a role of firm support. However, at the upper part of the pipe jacking, the steel sheet piles can only be set with lateral support, and the upper part of the pipe jacking is semicircular, so there is a blind spot in geological support, which eventually leads to soil collapse accidents.

[0003] During construction, bamboo plywood is usually used to tie the left and right sides of the jacking pipe, but it is difficult to operate on site. If the soil pressure is not well controlled, it can easily cause upper geological collapse, bringing difficulties to the construction. Utility Model Content

[0033] Reference Figure 1 and Figure 2 The adjustment assembly 4 includes a vertical first hydraulic cylinder 41 located on the upper side of the limit plate 3. The telescopic rod of the first hydraulic cylinder 41 faces the limit plate 3 and is fixedly connected to the side wall of the limit plate 3. The first support plate 11 is provided with a first sliding groove 112 that is connected to the adjustment hole 111 and adapted to the end of the first hydraulic cylinder 41 away from the limit plate 3. The end of the first hydraulic cylinder 41 away from the limit plate 3 is inserted into the first sliding groove 112 and is slidably connected to the first support plate 11 along the length direction of the limit plate 3.

[0034] A horizontal second hydraulic cylinder 42 is provided on the side wall of the limit plate 3, and the telescopic rod of the second hydraulic cylinder 42 faces the limit plate 3 and is fixedly connected to the side wall of the limit plate 3. A second sliding groove 113 is provided on the first support plate 11, which is connected to the adjustment hole 111 and adapted to the end of the second hydraulic cylinder 42 away from the limit plate 3. The end of the second hydraulic cylinder 42 away from the limit plate 3 is inserted into the second sliding groove 113 and is slidably connected to the first support plate 11 along the vertical direction.

[0035] The first supporting plate 11 and the second supporting plate 12 are arranged at intervals and spliced ​​with each other, and the adjacent first supporting plate 11 and the second supporting plate 12 are fixed by a connecting assembly. At this time, the first supporting plate 11 and the second supporting plate 12 form a whole. The position of the limit plate 3 in the height direction of the support frame 1 is adjusted by extending or shortening the telescopic rod of the first hydraulic cylinder 41. At this time, the second hydraulic cylinder 42 slides on the support frame 1 with the movement of the limit plate 3. The position of the limit plate 3 in the length direction of the support frame 1 is adjusted by extending or shortening the telescopic rod of the second hydraulic cylinder 42. At this time, the first hydraulic cylinder 41 slides on the support frame 1 with the movement of the limit plate 3 until the limit hole 31 is aligned with the pipe, so as to limit the pipe during the pipe jacking process, and when the end of the pipe passes through the limit hole 31, the support frame 1 close to the side of the limit plate 3 supports the pipe in the height direction, thereby improving the stability of the pipe.

[0036] Reference Figure 1 and Figure 3The connection assembly includes a connection plate 2 fixedly connected to the vertical side wall of the second support plate 12. The connection plate 2 is vertical and the cross section of the connection plate 2 in the horizontal direction is set to a T shape. The width of the connection plates 2 on the same second support plate 12 on the side away from each other is greater than the width on the side close to each other. The first support plate 11 is provided with vertical connection grooves 114 on both sides thereof, which are adapted to the connection plate 2 and penetrate the first support plate 11. The connection plate 2 is inserted into the corresponding connection groove 114 and fixedly connected to the first support plate 11 by bolts.

At this time, fix the connecting plate 2 and the first supporting plate 11 by bolts to complete the installation of the support frame 1.

[0038] When the connecting plate 2 is inserted into the connecting groove 114 , the shape of the connecting plate 2 limits the first supporting plate 11 and the second supporting plate 12 in the horizontal direction, making it easy to fix the connecting plate 2 and the first supporting plate 11 by bolts.

[0039] Reference Figure 1 and Figure 3 Except for the side close to the limiting plate 3, the other side walls of the support frame 1 are all provided with a vertical protective net 5 in contact with the side wall of the support frame 1. The protective net 5 is provided with a vertical tensioning roller 51 corresponding to the connection between the first support plate 11 and the second support plate 12. In the embodiment of the present application, 8 rollers are provided.

[0040] Reference Figure 3 The fixing assembly includes fixing plates 6 arranged at the four corners of the first supporting plate 11 on the side close to the protective net 5. The ends of the fixing plates 6 on the same side of the same first supporting plate 11 in the vertical direction that are away from each other are hinged to the first supporting plate 11. The first supporting plate 11 and the adjacent second supporting plate 12 are both provided with arc grooves 115 on the sides close to each other. The adjacent arc grooves 115 are spliced ​​together to form a semicircular shape that is adapted to the tensioning roller 51 and has an opening facing the inside of the support frame 1. The tensioning roller 51 is inserted into the corresponding arc groove 115. The fixing plate 6 rotates in the direction close to the tensioning roller 51 until it contacts the side wall of the tensioning roller 51, and the tensioning roller 51 is fixed by a bolt passing through the tensioning roller 51 and being threadedly connected to the first supporting plate 11.

[0041] Turn the tensioning roller 51 and adjust the length of the protective net 5 until the protective net 5 is tensioned and can fit with the first support plate 11 and the second support plate 12 at the same time, turn the fixing plate 6 in the direction away from the first support plate 11, and make the side wall of the protective net 5 contact with the side wall of the first support plate 11 and the second support plate 12, insert the tensioning roller 51 in the corresponding arc groove 115, and then drive the fixing plate 6 to rotate in the direction close to the protective net 5 until the fixing plate 6 contacts with the side wall of the protective net 5, and fix it to the first support plate 11 by bolts passing through the fixing plate 6 and the tensioning roller 51, thereby completing the fixing of the protective net 5.
