Concrete pouring device and method for ultrahigh steel pipe concrete column tremie method

Abstract

The invention relates to a concrete pouring device and a concrete pouring method for an ultrahigh steel pipe concrete column tremie method. Inner baffles are arranged at intervals in a steel pipe. Pouring holes are formed in the middle parts of the inner baffles. Air vents are distributed on the peripheries of the inner baffles. The device comprises a column top movable platform which is connected onto the top of the steel pipe, a guide pipe which is inserted into the steel pipe, and a feeding hopper which is connected onto the upper part of the guide pipe. The column top movable platform consists of a joint steel pipe 5, a main beam, a secondary beam, diagonal bracings, a steel plate and a guardrail. Two clamping plates which can be upwards turned over are connected at the mouth of the top of the joint steel pipe through hinges. Guide pipe clamping mouths which are used for positioning the guide pipe are formed in the middles of the two clamping plates. The bottom of the joint steel pipe is fixedly connected with the steel pipe. The guide pipe is formed by sections in connecting way. The guide pipe is downwards inserted into the steel pipe through the joint steel pipe. The concrete pouring device and the concrete pouring method for the ultrahigh steel pipe concrete column tremie method have the advantages that the one-step pouring height can reach 29m, the requirement on the construction period and process can be met, the concrete column is detected as acceptable through ultrasonic detection, the pouring quality is reliable and the device and the method are particularly suitable for the pouring construction of ultrahigh steel pipe concrete with dense baffle holes.

Description

technical field [0001] The invention relates to a concrete pouring device and method for a steel pipe concrete column. Background technique [0002] Concrete filled steel tubes are widely used in high-rise buildings and long-span structures. At present, the pouring methods of steel pipe concrete include manual layer-by-layer pouring method, conduit pouring method, pumping jacking method and high-level drop without vibration method. However, the artificial layer-by-layer pouring method cannot be used for super-high concrete filled steel tubes with internal partitions. The construction preparation time of the pumping jacking method is long, and it is necessary to install flow-stop devices, short pipes, and also need to open feed ports and set pressure relief holes on the steel pipe column. The construction control procedures and construction devices are very complicated. In the case that there is an inner annular partition inside the steel pipe, the hole in the center of the...
