Abstract

The invention discloses a porous pre-buried channel which comprises a square tube and a plurality of anchors fixed to the upper surface of the square tube. The bottom of the square tube is provided with a plurality of strip-shaped through holes which are used for installing T-shaped bolts. The invention further discloses a machining method of the pre-buried channel. The machining method comprises the following steps that the square tube of the preset length is cut out; the square tube is subjected to refined grain treatment; the strip-shaped through holes are formed in the lower surface of the square tube; and the anchors are fixedly connected to the upper surface of the square tube. According to the porous pre-buried channel and the machining method thereof, movement of the T-shaped bolts in the strip-shaped through holes can be ensured, and on the premise that the center distances of the adjacent T-shaped bolts can be adjusted, the strength of the pre-buried channel can be improved through the joints of the adjacent strip-shaped through holes, and installed equipment does not move or fall off when the T-shaped bolts are stressed in the axial direction of the channel.

Description

technical field

[0001] The invention relates to the field of building construction, in particular to a porous pre-embedded channel and a processing method thereof. Background technique

[0002] The urban comprehensive pipeline corridor is a municipal pipeline comprehensive corridor underground in the city, that is, a tunnel space built underground, and various pipelines such as municipal, electric power, communication, gas, water supply and drainage, heat, garbage transportation, etc. are intensively laid in the tunnel space Among them, it is a municipal utility pipeline complex.

[0003] The comprehensive pipe gallery is a concrete structure, and a multi-layer support structure is set in the pipe gallery to support and fix various pipelines. For the fixation of the bracket on the concrete structure, chemical anchor bolts or pre-embedded flat steel sheets are mostly used at present. Among them, the chemical anchor bolts have the disadvantages of destroying the concrete str...
