Embodiment 1

[0027] Such as Figure 1 to Figure 4 As shown, a method for installing the pre-buried groove of urban underground comprehensive utility gallery, the steps are as follows:

[0028] Step 1, making channel bolts

[0029] One end of the channel bolt has a nut, and the other end is set as a card according to the shape and size of the channel section of the embedded groove 4. The size of the card is slightly smaller than the channel size, which is convenient for installation and later removal. The channel bolt can be reused , saving costs.

[0030] Step 2, according to the screw size of the channel bolts and the position required by the design of the embedded groove 4, holes are pre-drilled on the formwork 2. Since the distance between the pre-embedded grooves 4 is uniform, the position of the holes on the formwork 2 is fixed, and the formwork 2 can continue to be used after the formwork is removed without re-drilling the holes to damage the formwork.

[0031] Step 3, install the...

Abstract

The invention discloses an installation method for an urban utility tunnel pre-buried channel. The installation method comprises the steps of making a channel bolt; trepanning a template according tothe screw size of the channel bolt and the required design position of a pre-buried channel in advance; installing a clip of the channel bolt in the pre-buried channel; fixing the pre-buried channel to the template by the channel bolt and nut; and performing engineering installation of the template. According to the installation method, the pre-buried channel is fixed to the template by the channel bolt, not only can the installation quality of the pre-buried channel be ensured, but also the template is not damaged; and meanwhile the channel bolt can be reused, so that the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of installation engineering of pre-buried grooves of urban underground comprehensive pipe gallery, and in particular relates to an installation method of pre-buried grooves of urban underground comprehensive pipe gallery. Background technique [0002] Urban comprehensive utility corridor refers to the pipeline public tunnel built underground in the city. Two or more municipal pipelines such as electricity, communication, gas, water supply, heat, and drainage are laid in the tunnel, and unified planning, design, construction and maintenance are implemented. Among them, cable trays for electricity, communication, etc. and gas pipelines are mostly fixed on the embedded grooves, so the installation accuracy of the embedded grooves is required to be high. [0003] The traditional installation method of embedded groove generally adopts the following methods: [0004] (1) The channel is fixed on the steel bar of t...
