Description

Technical Field

[0001] The utility model relates to the technical field of subway station protection, and more specifically, to a protective support structure for a newly built subway station. Background Art

[0002] With urban development and population growth, subways, as an efficient and convenient means of transportation, are playing an increasingly important role in urban transportation. To meet this growing demand, many cities are continuously building new subway lines and stations. However, the construction of new subway stations often impacts nearby operating stations, such as ground subsidence and structural deformation. These impacts not only endanger the safety of existing stations but also affect the normal operation of the subway. Therefore, protecting the safety of adjacent operating stations has become a key issue that needs to be addressed during the construction of new subway stations.

[0003] Currently, commonly used protective support structures include underground continuous walls, bored piles, and SMW piles. These protective support structures can effectively protect the safety of adjacent operating stations to a certain extent, but in practical application, some problems and shortcomings still exist.

[0004] For example, the construction of underground continuous walls is difficult and costly; during the trenching construction of underground continuous walls, there is a risk of trench wall collapse during the trenching process or during the grouting process after trenching.

[0005] In order to solve the above problems, a protective support structure for a newly built subway station is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a protective support structure for a newly built subway station to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a protective support structure for a newly built subway station, comprising a lifting frame, wherein the bottom end of the lifting frame is symmetrically connected to an outer support plate, an inner plate is provided on the inner side of each outer support plate, a plurality of connecting rods are connected between adjacent outer support plates and inner plates, a guide rod is installed on the outer side of each inner plate, and both guide rods are slidably connected to the lifting frame.

[0008] The lifting equipment is used to connect and fix the lifting frame, and then the entire support structure is lifted and moved to be placed in the groove, and the positioning is adjusted so that the bottom of the two inner plates are pressed against the bottom end of the inner groove. Then the lifting frame is pressed down to make the outer support plate descend. Under the action of each connecting rod, the inner wall of the groove is supported and fixed, so that the collapse of the inner wall of the groove can be avoided during pouring. When dismantling the support structure, the lifting frame can be directly lifted to loosen the outer support plate, thereby improving the convenience of disassembly.

[0009] Preferably, slide rails are symmetrically arranged on the bottom end of the lifting frame, and a slide seat is slidably connected to the bottom of each slide rail, and each slide seat is respectively installed on the top end of the corresponding outer support plate.

[0010] Preferably, a guide rod is installed on the inner side of the inner plate, and guide holes are symmetrically opened on the lifting frame, and the guide rod and the guide hole slide vertically.

[0011] Preferably, a connecting buckle is installed at the top of the lifting frame, and the connecting buckle is located in the middle of the lifting frame.

[0012] Preferably, a plurality of fixing brackets are installed on opposite sides of the outer supporting plate and the inner supporting plate, and both ends of each connecting rod are hinged to the corresponding fixing bracket.

[0013] Technical effects and advantages of this utility model:

[0014] By pressing the lifting frame downward, the outer support plate is lowered, and the bottom of the inner plate is connected to the bottom of the groove, so that the connecting rod generates a supporting force on the outer support plate, so that the outer support plate is moved outward under the cooperation of the slide seat and the slide rail, so that the outer support plate can be pressed against the inner wall of the groove. The strength of the support against the inner wall of the groove can be changed by adjusting the lowering height of the lifting frame, so that it can be adjusted according to the excavation width to avoid the collapse of the inner wall of the groove during the pouring process.

[0015] When the lifting frame is lowered and the bottom of the inner plate is supported by the bottom of the groove, the guide rod is extended along the guide hole, while the position of the inner plate remains unchanged, thereby being able to control the pouring width.
