Description

Reinforcing steel bar stacking bracket for shield tunnel connection channel construction Technical Field The utility model belongs to the field of building construction, and particularly relates to a reinforcing steel bar stacking bracket for shield tunnel connection channel construction. Background In recent years, urban rail transit networks are quickened by multiple cities nationwide to excavate urban underground spaces, reasonably dredge traffic flow and solve the problem of traffic jam existing in the current city. The subway tunnel connecting channel has small engineering scale and large construction risk. The communication channel engineering is a channel for connecting the two tunnels in the uplink and the downlink, and is generally constructed after the establishment of the tunnels in the uplink and the downlink. The construction period of the subway tunnel connecting channel engineering is required to be tight, the construction period is short, and professional construction procedures are multiple. The communication channel engineering is the control engineering of the whole tunnel and is also the key control construction period of the engineering. The method relates to a plurality of professional procedures such as drilling, freezing, excavating, grouting, reinforcing steel bars, waterproofing, templates, concrete, grouting and the like, and has more parallel cross operations and high requirements on construction organization and construction management. The subway communication channel is used as a component part of subway construction, and standardized construction of the communication channel becomes a key ring for improving the safety and civilization construction of the whole tunnel construction. The construction of the connecting channel is basically carried out after the tunnel is formed, so that the construction of the connecting channel is easy to cause certain influence on the environment of the formed tunnel, such as the stacking confusion of materials required by the construction of the connecting channel, the influence on the transportation of materials by vehicles, the pollution of the construction materials of the connecting channel to the formed tunnel and the like. The development of the standardized construction of the connection channel construction has important significance for creating construction civilized construction sites and improving the appearance quality of subway tunnels. The steel bar engineering is one of the most critical working procedures in the construction of connecting channels, and the supply of the semi-finished steel bars is ensured to be an important guarantee for improving the construction work efficiency. Because the ground construction site is limited, in order to improve the construction efficiency, the reinforcing steel bar raw materials are transported to the construction site of the connecting channel for stacking for standby after being processed in advance, and the higher requirements are clearly put into the material stacking site at the connecting channel in the combined planning tunnel. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides a reinforcing steel bar stacking bracket for shield tunnel connecting channel construction. The utility model adopts the following technical scheme to realize the aim: A reinforcing steel bar stacking bracket for shield tunnel connection channel construction is characterized by comprising at least two placement devices, wherein each placement device comprises a connecting plate and a limiting rod connected with the connecting plate, and the connecting plate is connected with a bolt hole of a tunnel segment through a connecting nut. The bolt holes of the tunnel segments of the adjacent placement devices are positioned on the same horizontal line. The limiting rod is an iron rod, the connecting plate is an iron plate, and the limiting rod is connected with the connecting plate in a full-welded mode. The height of the limiting rod is 0.8-1.5m. The top of the limiting rod is provided with a sponge package, and the outer side of the sponge package is provided with a color adhesive tape. The rod body of the limiting rod is provided with a reflecting strip. The limiting rods are connected by using a warning belt.
