Embodiment 1

[0039] Embodiment 1: as figure 1 and Figure 4 As shown, a connection device between prefabricated pipe sections includes a connecting piece, the connecting piece is passed through the reserved channel 6 on the prefabricated pipe section 5 and the connecting piece passed through the adjacent prefabricated pipe section 5 is detachably connected; An adjustment mechanism is sleeved on the connecting piece, and the adjustment mechanism cooperates with the reserved channel 6 on the prefabricated pipe joint.

[0040] The connecting piece includes a flexible connecting rope, the length of the flexible connecting rope is slightly longer than the longitudinal length of the pipe joint, and its diameter is smaller than the diameter of the reserved channel. The flexible connecting rope is passed through the reserved channel 6 on the prefabricated pipe joint 5 and The flexible connecting rope passing through the reserved channel 6 on the adjacent prefabricated pipe section 5 is detachably...

Embodiment 2

[0043] Embodiment 2: A construction method using a prefabricated pipe internode coupling device, comprising the following steps:

[0044] S1. Prefabricated pipe internode connection device preparation: firstly prepare sufficient flexible connectors, fixedly sleeve the tube capsule on each flexible connector, and carry out trial docking of each flexible connector;

[0045] S2. Construction of the first section of prefabricated pipe joints: if Figure 5 and Figure 6As shown, after the first section of the prefabricated pipe section is assembled in place in the tunnel, the flexible connector is inserted into the reserved channel 6 on the first section of the prefabricated pipe section simultaneously, and the flexible connector is passed through the reserved channel to leave the connecting joint. Then use the expansion tube to inflate or fill the reserved channel 6 with liquid, or use other elastic tubes to self-adaptively fill the reserved channel 6 driven by the flexible conne...

Abstract

The invention provides a prefabricated pipe joint connecting device and a construction method applying the same. The prefabricated pipe joint connecting device comprises connecting pieces, wherein theconnecting pieces are arranged in reserved channels in prefabricated pipe joints in a penetrating mode, and the connecting pieces arranged in the adjacent prefabricated pipe joints in a penetrating mode are detachably connected; and the connecting pieces are sleeved with adjusting mechanisms, and the adjusting mechanisms are matched with the reserved channels in the prefabricated pipe joints. Bymeans of the series connection type connecting pieces, it is guaranteed that communication between the prefabricated pipe joints is not limited by the length of a rope any more, the reserved channelsare filled with pipe bags arranged on the connecting pieces in a sleeving mode, soil or grout or other impurities can be prevented from blocking, the connecting pieces are integrally replaced with anchor cables, and the resistance of the whole pipe joints is improved through anchor cable tensioning.

Description

technical field [0001] The invention relates to the technical field of connection of prefabricated pipe sections in tunnels, in particular to a connection device between prefabricated pipe sections and a construction method for its application. Background technique [0002] In the field of underground engineering, there are more and more cases of mechanized construction, which is also a development direction of future construction methods. The prefabricated structures (such as pipe joints) matched with mechanized construction are mostly connected by bolts. The main body includes opposite side walls. There are pre-embedded steel boxes inside the side walls. There are pre-embedded screw holes on the top and bottom of the pre-embedded steel boxes. The corresponding pre-embedded screw holes are connected to bolts and assembled through multi-piece composite segments. To form a complete pipe joint, although the overall degree of mechanization has been improved, there are still ma...
