Embodiment Construction
[0033] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described further specifically, as Figure 2-5 As shown, the device is composed of I-beam 1, cushion block 2, pipe gallery purlin 3, pile purlin 4, Z-shaped frame 5, purlin bracket 6, and L-shaped cushion block 7. First, install the purlin bracket 6 on the support pile; the second step is to fix the pile purlin 4 on the purlin bracket 6; the third step is to place one end of the Z-shaped frame 5 on the roof of the comprehensive pipe gallery, and fix the other end on the Purlin bracket 6; the fourth step is to place the L-shaped pad 7 at the corner of the roof of the comprehensive pipe gallery. The purpose of the L-shaped pad 7 is to transfer the load of the purlin 3 to the comprehensive pipe gallery evenly, avoid The load pressure is too concentrated; the L-shaped pad 7 can be densely arranged according to the load; the fifth step is to fix the purlin 3 of the...

The invention provides a support replacement device for a foundation pit of a comprehensive pipe gallery, including a support replacement device located between the support piles of the foundation pit and the main structure of the comprehensive pipe gallery. purlin bracket, the Z-shaped frame installed on the roof of the pipe gallery, and the pile purlins and pipe gallery purlins respectively fixed on the purlin bracket and Z-shaped frame, between the pile purlins and the pipe gallery purlin There is an I-beam, one end of the L-shaped frame is placed on the roof of the comprehensive pipe gallery, and the other end is fixed above the horizontal support plate of the purlin bracket. The device is simple in structure, easy to operate, can be quickly installed and disassembled, and can be reused. It can save materials and effectively shorten the construction period; it can also save space and backfill the fertilizer tank between the comprehensive pipe gallery and the support piles. Provide convenience.
Description
technical field [0001] The invention relates to the technical field of comprehensive pipe gallery engineering, in particular to a support replacement device for a foundation pit of a comprehensive pipe gallery and an installation method thereof. Background technique [0002] In the comprehensive pipe gallery project in China, the foundation pit in the form of support is basically narrow and long. During the construction of the comprehensive pipe gallery, the support is often replaced. At present, the support replacement is generally designed between the roof of the comprehensive pipe gallery and the support pile Pour reinforced concrete slabs with a thickness greater than or equal to 300mm in the gap, such as figure 1 As shown, the brace replacement operation can only be carried out after the strength of the reinforced concrete to be poured meets the design requirements. The first construction period of this method is longer, which affects the construction progress; after t...
