[0002] Steel structure has the advantages of high bearing capacity, light weight and good seismic performance. It is widely used in large space and large span building structures. Among them, steel truss structure is widely used in large span structure due to its high efficiency of structural force system. Concrete structure has good compressive performance, large cross-section and high rigidity, and is usually used for supporting columns of tall space roof.

[0003] At present, the top-down pouring method of concrete in truss lattice columns is difficult to construct, relatively inconvenient to operate, complicated procedures, low efficiency, difficult to control the overall construction quality, and prone to defects. During the concrete pouring process, the height control is not in place. Since aggregates are easy to settle and aggregates and cement slurry are easy to separate, bubbles are easy to generate in the concrete during the pouring process and are difficult to fully discharge, which may cause the concrete to be loose, thereby affecting the quality of the concrete. If the pouring speed is not well controlled, cold joints are easy to form at different heights, affecting the integrity of the structure. Summary of the invention

During the concrete pouring process, the height control is not in place. Since aggregates are easy to deposit and aggregates and cement slurry are easy to separate, bubbles are easy to generate in the concrete during the pouring process and are difficult to fully discharge, which may cause the concrete to be not dense, thereby affecting the concrete quality. If the pouring speed is not well controlled, cold joints are likely to be formed at different heights, affecting the integrity of the structure.

[0006] Preferably, a movable gate plate is provided between the first backflow check valve tube and the second backflow check valve tube, and a through hole is provided on the movable gate plate.

[0007] Preferably, an overflow exhaust hole is provided on the top of the truss lattice column.

[0008] The concrete jacking construction process in the truss lattice column includes the following steps: S1. When producing steel columns, reserve the concrete pouring pipe and overflow vent in advance, and then calculate the required pumping pressure equipment according to the diameter and height of the steel column; S2, welding a second pipe clamp at the reserved concrete pouring pipe and connecting it to the second backflow check valve pipe; S3, connect the pumping pipe with the first return check valve pipe, and fix the first return check valve pipe and the second return check valve pipe together with stud bolts, push up the movable gate plate to connect the through hole with the second return check valve pipe, and then start pumping concrete. After the concrete pouring is completed, push down the movable gate plate to close the movable gate plate; S4. After the concrete solidifies, remove the first and second return check valve pipes. After all the pouring is completed, cut off the concrete pouring pipes, weld the sealing plates, and apply anti-rust paint. S5. Check whether the concrete at the top of the steel column is poured densely. If there is any gap, fill it with grouting material through the overflow vent hole at the top.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1.
