Technical Field

[0001] The utility model relates to a supporting mechanism, in particular to a concrete structure reinforcement device. Background Art

[0002] The concrete foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the situation of nearby buildings on site, and waterproofing and drainage work should be done. If the excavation is not deep, the side slope can be used to stabilize the earth slope, and the slope size is determined according to relevant construction regulations. For deeper excavations and nearby buildings, the concrete foundation pit wall reinforcement support mechanism can be used for support. The concrete foundation pit support mechanism of the existing technology is often less versatile. In the face of concrete foundation pits of different depths in the project, it is necessary to prepare a variety of support mechanisms in advance, which leads to an increase in economic costs. Therefore, a new type of concrete structure reinforcement device is urgently needed to solve the above technical problems. Utility Model Content

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Reference Figure 1-3As shown, a preferred embodiment of the utility model provides a concrete structure reinforcement device, including a concrete foundation pit 1 and an L-shaped support mechanism for reinforcing and supporting the side wall of the concrete foundation pit 1: the L-shaped support mechanism includes a support vertical plate 4, the side wall of the support vertical plate 4 is in contact with the side wall of the concrete foundation pit 1, a plurality of first hydraulic cylinders 5 are fixedly installed on the upper surface of the support vertical plate 4, and a support cross plate 2 is fixedly installed on the top of the piston rod of the plurality of first hydraulic cylinders 5, a plurality of second hydraulic cylinders 6 are fixedly installed on the lower surface of the support vertical plate 4, and a plurality of second hydraulic cylinders 6 are fixedly installed on the top of the piston rod of the plurality of second hydraulic cylinders 6, the support bottom pile 3 is fixedly installed, the support cross plate 2 is fixedly installed at the top edge of the concrete foundation pit 1, and the support bottom pile 3 is inserted in the concrete foundation pit 1, and when the piston rods of the plurality of first hydraulic cylinders 5 and the plurality of second hydraulic cylinders 6 are extended and retracted, the relative distance between the support cross plate 2, the support vertical plate 4 and the support bottom pile 3 can be changed, thereby changing the size of the entire L-shaped support mechanism.

[0017] Among them, a protective cavity 7 is opened in the supporting vertical plate 4, and a plurality of third hydraulic cylinders 8 are fixedly installed in the protective cavity 7. The piston rods of the plurality of third hydraulic cylinders 8 pass through and are slidably installed in the supporting vertical plate 4, and a connecting pile 9 is fixedly installed on the top of the piston rod of the third hydraulic cylinder 8. When the piston rod of the third hydraulic cylinder 8 is extended, the tip of the connecting pile 9 can penetrate into the concrete foundation pit 1, thereby enhancing the stability of the supporting vertical plate 4 on the side wall of the concrete foundation pit 1.

[0018] Finally, expansion bolts 10 are installed through the surface of the supporting cross plate 2, and the supporting cross plate 2 is fixedly installed at the top edge of the concrete foundation pit 1 by the expansion bolts 10. By tightening the expansion bolts 10 into the concrete foundation pit 1, the stability of the supporting cross plate 2 in the concrete foundation pit 1 can be enhanced, thereby ensuring the normal operation of the supporting mechanism.

[0019] When support operations are required, first start a number of first hydraulic cylinders 5 according to the depth of the concrete foundation pit, and then adjust the relative distance between the support vertical plate 4 and the support horizontal plate 2, then place the support horizontal plate 2 on the concrete foundation pit 1 and make the side wall of the support vertical plate 4 fit the concrete foundation pit 1, and then tighten the expansion bolt 10 so that one end of the expansion screw 12 penetrates into the concrete foundation pit 1, further strengthening the stability of the L-shaped support mechanism on the concrete foundation pit 1. When the concrete foundation pit is deepened during construction, start a number of second hydraulic cylinders 6, and the support bottom pile 3 moves downward until the bottom tip of the support bottom pile 3 penetrates into the concrete foundation pit 1.
