The application is a kind of exhibition hall ground ditch inside electromechanical comprehensive pipeline assembly type construction method, which comprises the following steps: electromechanical comprehensive pipeline module division, main pipe ditch support design, branch pipe ditch support design, factory prefabrication, factory or ditch edge assembly, segmented hoisting and segmented installation, positioning adjustment support fixing, alignment connection between alignment sections, fire hydrant box and comprehensive box installation. The method is beneficial to the rapid and reasonable construction of the exhibition hall ground ditch inside electromechanical comprehensive pipeline, the designed pipe ditch support realizes the purpose of factory prefabrication and on-site assembly type construction, and solves the technical problem that the construction of the electromechanical comprehensive pipeline in the exhibition hall ground ditch is relatively difficult due to the narrow space. In addition, the fire hydrant box in the method is newly designed in the principle of convenient use, and can be directly pulled up when needed, which is simple to operate and convenient to use. Practice proves that the method is safe and reliable, convenient to construct, and good in appearance, and achieves the expected index and target.

This invention relates to the technical field of tunnel construction methods, and in particular to a method for anchoring and pulling out anchors in the excavation section of a hard rock tunnel. The method includes the following steps: S1, setting the outline of the excavated rock mass and creating a weakened structural surface along the outline; S2, driving several anchor rods into the excavated rock mass and creating a rock mass structural surface with several anchor rod ends; S3, using construction machinery to pull out the anchor rods; S4, removing slag; S5, subsequent rock mass support. This invention features simple process steps, a reasonable design, convenient construction, and good performance. It can easily complete the excavation and construction process of hard rock tunnels, ensuring safety and guaranteeing the construction period.
