Embodiment

[0021] Example: Inner Mongolia 3052 chemical fertilizer production project installation and construction example of ammonia plant.

[0022] The process flow of the present invention is: assemble the construction platform → make positioning templates and fix and level them on the construction platform → pre-embedded anchor bolts are inverted → pre-embedded anchor bolts are transported as a whole and hoisted in place → pre-embedded anchor bolts installation size review → Rebar binding → Concrete pouring → Removal of positioning formwork and protection of exposed threads.

[0023] The assembled construction platform.

[0024] 1. The construction platform is erected. This platform is the same as the prefabricated assembly platform of non-standard equipment, H-shaped steel and steel structure. The existing prefabricated platform or assembled construction platform can be used. When the platform is assembled, the prefabrication of future steel structures and non-standard equipment sh...

Abstract

The invention discloses an inverted installation method of embedded foundation bolts of a large tower-type equipment foundation, and belongs to the field of building construction. The inverted installation method is characterized in that locating formworks and the embedded foundation bolts are placed in the foundation for conducting concrete pouring after being manufactured and assembled firstly. The inverted installation method is short in installation time, thereby shortening the construction period and reducing the project cost. Meanwhile, center displacement between all the embedded foundation bolts, the topmark height difference of all the bolts and the exposed length deviation of all the bolts are all within the standard permissible range, and the construction precision is high.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for pre-embedded anchor bolts in the foundation of large-scale tower equipment. The large-scale tower equipment described in the present invention comprises methanol washing tower, CO 2 Analysis tower, H 2 S concentration tower and methanol water separation tower. Background technique [0002] There are many pre-embedded anchor bolts for the foundation of reinforced concrete large-scale tower equipment, and there are many industrial construction equipment foundations. The pre-embedded anchor bolts involved are of many specifications and large quantities. It is difficult and requires high construction precision. Once a large deviation occurs in individual bolt pre-embedding, it will directly affect the normal installation of the equipment. [0003] At present, the construction method of pre-embedded anchor bolts for large-scale tower equipm...
