Embodiment

[0015] A rapid construction technology for pre-embedded bolt groups in curved rail foundations of unloading pits, characterized in that it includes the following steps:

[0016] Step 1), pre-embedded component processing. Select several channel steels, and the channel steels should be straight without bending; determine the length of the channel steels according to the number of bolts in each row or column, mark the length on the entire channel steels with a stone pen, and number the channel steels; then carry out Cutting, the cutting surface must be neat; after the channel steel is cut, mark the bolt hole position on the channel steel according to the design position of the bolt corresponding to the numbered channel steel, and use a drill to drill the hole at the marked position, and the hole diameter is 2mm larger than the bolt diameter ; After the hole is drilled, the channel steel is welded into a whole according to the number, and the bolt design position is verified.

Abstract

The invention discloses a quick construction technology for a pre-buried bolt group of an ore dumping pit curved-track foundation. The quick construction technology comprises the following steps: step 1), processing a pre-buried component; step 2), putting a channel steel rack to a designed position, and fixing the channel steel rack; step 3), putting bolts into reserved bolt holes for fixing; and step 4), re-checking and rectifying a deviation, wherein in a concrete casting process, positions of the bolts are frequently checked, and the positions of the bolts are regulated to designed positions after deviation is found. According to the quick construction technology disclosed by the invention, the design is reasonable, position cutting holes are formed in channel steel according to bolt designs, channel steel and bolts are pre-buried according to the designed positions, less labor power is consumed, the construction period is short, precision is high and construction is simple and convenient.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a rapid construction technology of pre-embedded bolt groups for curved rail foundations of unloading pits. Background technique [0002] There are many pre-embedded bolts for the curved rail foundation of unloading pits in metallurgical underground mines, which are complex and require high precision. Generally, single bolts are used for pre-embedding one by one. The traditional pre-embedding method consumes a lot of construction time and manpower, and has a large error and low precision. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects and provide a rapid construction technology of pre-embedded bolt group for curved rail foundation of unloading pit with reasonable design, less manpower consumption, short construction period, high precision and simple construction. [0004] ...
