Based on the embodiments in 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.

[0025] See also Figure 1-4 The utility model provides an embodiment: a steel sleeve device for receiving a rectangular jacking pipe, comprising a base 1 and a jacking pipe structure 3, a jacking machine 2 is arranged above the base 1, a jacking pipe structure 3 is arranged on the right side of the jacking machine 2, a jacking pipe cylinder 301 is arranged on the right side of the jacking machine 2, a mounting seat 302 is arranged on the right side of the jacking pipe cylinder 301, a fixed cylinder 303 is arranged on the outer side of the mounting seat 302, and limiting plates 306 are arranged on both sides of the base 1.

[0026] Specifically, the jacking cylinder 301 is sleeved with the base 1, two groups of jacking cylinders 301 are arranged, and the mounting seat 302 forms a movable structure through the jacking cylinder 301 and the base 1. The jacking cylinder 301 is extended to push the steel sleeve into the tunnel.

[0027] Specifically, the fixed cylinder 303 is fixedly connected to the mounting seat 302. Multiple groups of fixed cylinders 303 are arranged. A clamping plate 304 is connected to one end of the fixed cylinder 303. The clamping plate 304 is L-shaped. The clamping plate 304 forms a movable structure with the fixed cylinder 303 and the mounting seat 302. The fixed cylinder 303 is extended to fix the clamping plate 304 on the inner surface and the left side of the steel sleeve, which is used to clamp the steel sleeve during the jacking operation. The L-shaped clamping plate 304 can prevent the clamping plate 304 from being stuck between the steel sleeves during the jacking operation and affecting the work.

[0028] Specifically, a gasket 305 is adhered to the outer side of the card plate 304. The gasket 305 matches the size of the card plate 304. The gasket 305 is made of rubber. The gasket 305 can prevent the steel sleeve from slipping and can absorb vibrations in the system to protect the equipment from damage.

[0029] Specifically, two groups of limit plates 306 are provided, and the limit plates 306 are made of alloy steel. A bell mouth 307 is provided on the top of the limit plate 306, and a side baffle 308 is provided on the left side of the bell mouth 307.

The gasket 305 fits with the steel sleeve. The gasket 305 can prevent the steel sleeve from slipping and can absorb the vibration in the system to protect the equipment from damage. After the clamping plate 304 fixes the steel sleeve, the rotating motor 310 works to separate the rotating baffle 311 from the steel sleeve so that the steel sleeve can be pushed to the right. Then the jacking cylinder 301 is extended again to push the steel sleeve into the tunnel. The sliding roller 312 reduces the friction when the steel sleeve is pushed, which facilitates the operation.
