Concrete silo inner lining steel rail and warehouse wall slip form integrated construction method

Abstract

The invention discloses a construction method for integration of a concrete silo internal lining steel rail and a silo wall slip form. The method comprises the following steps: when the height of the internal lining steel rail is reached to the limestone silo construction according to design requirement, a silo wall inner formwork of the slip form is removed, and a ring steel plate is arranged at the design height of the silo inner side; effective number of steel rails are vertically arranged on the ring steel plate, and connected with one another through reinforcement steel bars, and the steel rails are welded with anchoring reinforcement steel bars connected with the silo wall reinforcement steel bars; after the position, distance and verticality of the steel rails are corrected, the joints between the reinforcement steel bars and the steel rails are welded; and the anchoring reinforcement steel bars and the silo wall reinforcement steel bars are tightly bound and arranged on the silo wall inner formwork again, and the concrete is continuously cast between the silo and the steel rails until the design height of the silo is reached, thereby improving the wearing resistance of the silo, prolonging the service life of the limestone silo by 15 to 20 years, reducing manpower consumption by 110 working days, reducing material consumption by 30,000 yuan, saving the time of welding, arrangement and secondary casting of the steel rails and shortening construction period by 30 days.

Description

Technical field: [0001] The invention relates to a construction method of a construction project, in particular to a construction method of a concrete silo structure project lined with steel rails. Background technique: [0002] In order to effectively protect the inner wall of the main structure of the limestone silo and prolong the service life of the silo, many silo structures are designed with rail linings (see attached figure 1 ). At present, the general construction method is to carry out the sliding form construction of the silo first. During the sliding form construction, the steel plate is pre-embedded on the inner wall of the silo. After the sliding form construction of the silo wall is completed, the lining rail is welded to the embedded steel plate on the inner wall of the silo and then concrete the gaps between the rails. Although this structure and construction method can achieve the effect of prolonging the service life of the silo, it has the following disa...

AI Technical Summary

Problems solved by technology

[0003] ①.Since the construction of the silo wall sliding formwork is carried out separately from the construction of the lining rail, that is, the silo wall sliding formwork is constructed to the roof of the warehouse first, and then the lining rail is installed, and the gap between the rails is carried out after the rail is installed. Concrete pouring, resulting in many processes, long construction period, and relatively large consumption of man-machine materials

[0004] ②. Since the lining rail and the embedded parts of the silo wall are fixed by welding, the gap between the rail and the silo wall is unavoidable, resulting in poor integrity of the rail and the silo wall

[0005] ③.Because the installation of lined steel rails inside the silo requires special operation scaffolding, and the welding workload of the steel rails and embedded parts is relatively large

[0006] ④. The formwork installation, reinforcement, concrete pouring and vibration of the concrete pouring layer between the rail gaps are relatively difficult, which should cause the concrete between the rails and the silo wall to be weakly bonded, and it is easy to loosen and fall off under vibration and washing, and the quality of the limestone silo is very poor. hard to get guarantee
