Detailed Description

The utility model discloses implement according to following step:

1. concrete foundation construction and comprehensive pipe trench arrangement

As shown in fig. 1 to 3, frame columns 9 are poured on a foundation 8 of a bulk cargo storage yard, and a comprehensive pipe trench 1 is excavated between two rows of frame columns 9 for installing and fixing inner and outer column bases of a steel support.

After the excavation of the foundation trench of the comprehensive pipe trench 1 is finished, templates on two sides of the inner side of the comprehensive pipe trench 1 are installed on the initially-set trench bottom concrete. The temporary support is arranged at the top of the trench wall to support the wooden template, and the wall concrete is removed when poured to the top. And when the trench wall concrete is poured to the height of the reserved cover plate groove, installing the processed battens on the cover plate groove position to continue pouring the concrete so as to reserve the position of the cover plate groove on the top of the trench wall.

When the concrete is poured, firstly, the ditch bottom concrete is poured, after the ditch bottom concrete is initially set (24 hours at normal temperature), the side wall concrete is poured by the vertical ditch wall formwork, and the ditch bottom concrete and the ditch wall concrete can be poured by one-time vertical formwork.

And after concrete pouring is finished, covering and watering for curing within 12 hours after slurry collection. And (4) dismantling the side mold when the compressive strength of the concrete reaches 1.2 Mpa.

Before the cover plate 6 is installed, a transportation pavement is built, and the two sides of the platform back are backfilled to prepare for hoisting. Before the cover plate is installed, two layers of felt with the thickness of 1cm are paved; marking the placing position of the cover plate in advance; during installation, the corresponding of the settlement joint at the lower part and the length of the plate end support are required to be noticed; after the installation is finished, the plate position is accurately adjusted, after the plate position is adjusted to the proper position, small stones are tightly propped, and then C20 small stone concrete is used for filling a gap between the table back and the cover plate. A water drainage hole 7 is preset in the foundation 8. The drainage holes are generally round holes with the diameter not less than 100 mm. The distance between the holes is about 2m, and coarse sand is mixed with coarse stone aggregate before the water outlet for water seepage.

The foundation 8 adopts a raft foundation, is integrally composed of a bottom plate, a beam and the like, is formed by connecting the independent foundations or the strip foundations below the column by a connecting beam, and integrally pouring the bottom plate below the connecting beam to form the raft foundation. The integrated foundation has good integrity and large bottom area, can reduce the stress of the foundation and can well resist the uneven settlement of the foundation.

2. Mounting of steel supports

The bulk cargo yard is provided with a bank protection retaining wall, the bank protection retaining wall is provided with an opening, and steel supports for installing and fixing the windproof dust suppression net are uniformly arranged according to the contour line interval of the position of the opening.

Hoisting the steel bracket part, and performing bidirectional straightening after taking place. The inner and outer column feet of the steel bracket are respectively fixed on the tops of two adjacent rows of frame columns,

after the steel support column base is installed in place and straightened, the steel support column base is screwed down through bolts, so that the bolts are prevented from loosening, and the stability of a steel frame is ensured.

After the steel support is installed, the tie bars among the steel support column feet are connected in time, so that a unit body with good stress is formed, the safety of the unit body is improved, and the instability of the steel support is prevented.

3. And installing and fixing the windproof dust suppression net.

As shown in fig. 4 and 5, the bimodal windproof dust suppression net is installed and fixed on the vertical surface of the steel bracket, so that the bimodal windproof dust suppression net and the retaining wall together form a vertical surface protective net for enclosing the bulk cargo storage yard.
