Problems solved by technology
[0004] like Figure 5 As shown, but during the expansion and contraction process of the front end pipe section 1 of the trunk room and the back end pipe section 2 of the trunk room, the sealing ring 4 is extremely vulnerable to the expansion and contraction of the front end pipe section 1 of the trunk room and the back end pipe section 2 of the trunk room. The high-pressure friction force makes the sealing ring 4 easily distorted and deformed, thus losing the water-stopping effect

Embodiment Construction
[0032] A kind of relay room with anti-pressure plate 5, such as figure 1 As shown, it includes a ring-shaped relay room front-end pipe joint 1, and one end of the relay room front-end pipe joint 1 is provided with a ring-shaped relay room rear-end pipe joint that telescopically slides with the relay room front-end pipe joint 1 2. Several jacks 3 are fixedly connected to the inner peripheral surface of the pipe joint 2 at the rear end of the relay room (there are six jacks 3 in this embodiment), which are used to push against the pipe joint 1 at the front end of the relay room, so that the relay room The front-end pipe section 1 and the rear-end pipe section 2 between the relay telescopically slide.
[0033] Such as figure 2 As shown, the inner peripheral surface of the rear pipe section 2 of the relay room is vertically provided with an annular rear collision ring 21 fixedly connected with the rear pipe joint 2 of the relay room. The bottom of the above-mentioned jack 3 is...

The invention discloses an intermediate jacking station with compression-resistant plates. According to the technical scheme, the intermediate jacking station comprises an intermediate jacking stationfront end pipe joint, an intermediate jacking station back end pipe joint and a jack for driving the intermediate jacking station front end pipe joint and the intermediate jacking station back end pipe joint to slide mutually, sealing rings are arranged on slippage planes of the intermediate jacking station back end pipe joint and the intermediate jacking station front end pipe joint, and the multiple compression-resistant plates fixedly connected with the intermediate jacking station back end pipe joint are arranged at a slippage gap of the intermediate jacking station back end pipe joint and the intermediate jacking station front end pipe joint. The intermediate jacking station has the advantages that the compression-resistant plates are arranged, so that high-pressure friction force generated by slippage of the intermediate jacking station front end pipe joint and the intermediate jacking station back end pipe joint to the sealing rings is reduced, the possibility of twisting deformation of the sealing rings is reduced, and the service life of the sealing rings is improved. In addition, the compression-resistant plates can have a certain limiting effect, and thus deformation extremities of the position of the stretchable gap of the intermediate jacking station front end pipe joint and the intermediate jacking station back end pipe joint are reduced.
Description
technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to a relay room with a pressure-resistant plate. Background technique [0002] The relay room is an indispensable equipment in long-distance pipe jacking construction. In the long-distance pipe jacking construction, it is necessary to push the pipe jacking machine into the construction plane through several hydraulic jacks, then connect the jacking pipe with the pipe jacking machine, and then push the jacking pipe into the tunnel through hydraulic jacks in turn. The distance of the jacking pipe jacking into the tunnel is too long, and the friction force between the jacking pipe and the inner surface of the tunnel is too large, which will affect the jacking efficiency of the hydraulic jack. Therefore, every certain distance between the jacking pipes will be installed between the jacking pipes. Between the relays, the function of the relays is to turn a long section...
