Description

Technical Field

[0001] The present application belongs to the technical field of building construction, and specifically relates to a groove rapid protection safety structure. Background Art

[0002] In industrial and civil buildings, since most of them are located in urban areas, the land red line planning is compact, the surrounding pipeline lines are intricate, and the surrounding buildings are relatively dense, the slope excavation in the traditional foundation construction stage is no longer applicable in this environment, and it is replaced by various vertical support systems. Larsen steel sheet piles, as a new type of building material, play an important role in retaining soil, water, sand retaining walls, unloading yard retaining walls, retaining walls, and embankment protection. Compared with traditional enclosures, Larsen steel sheet piles have the advantages of high strength, light weight, convenient and fast construction, good water stopping performance, good durability, recyclable and environmentally friendly.

[0003] However, at present, the ends of the supporting rods of the Larsen steel sheet piles act on the purlins on both sides, and the purlins are only spot-welded to the pile support surface, which makes it possible for the purlins to slide upward. Once the pile support surface tilts or settles due to various reasons, the pile support surface and the purlin will be relatively misaligned, affecting the supporting effect on both sides, and even causing the enclosure support to fail, bringing construction hazards. Utility Model Content

[0004] The purpose of the present application is to provide a groove rapid protection safety structure to solve the problem of unstable fixing of the surrounding purlin in the existing support system.

[0005] The purpose of this application is achieved through the following technical solutions:

[0026] The present application is further described below in conjunction with specific embodiments and drawings.

[0027] refer to Figure 1 to Figure 6 As shown, a trench rapid protection safety structure includes a pile support plate 1, a pile support surface 2, a support plate 3, a purlin 4, a back pressure plate 5, a support rod 6, a drainage pipeline 7, an electric pipeline 8 and a base 9. The support system adopts a Larsen steel sheet pile plus an internal support support structure.

[0028] The pile support surface 2 includes a plurality of pile support plates 1 spliced ​​together, that is, the pile support surface 2 is an action surface for enclosure support formed by a plurality of pile support plates 1. The pile support plates 1 are Larsen steel plates, which are pressed in by static pressure method, and the Larsen steel plates are hooked and spliced ​​together. The spliced ​​locks of the Larsen steel sheet piles should be evenly coated with mixed oil.

[0029] Or the pile support plate 1 is a corrugated steel sheet pile; or the pile support plate 1 is a straight sheet pile. The pile support surface 2 is arranged on both sides to provide enclosure and support for the soil on both sides, and to form a construction space between the pile support surfaces 2 on both sides.

[0030] A plurality of support plates 3 are welded and fixed on the inner side of the pile support surface 2, and a purlin 4 arranged in the longitudinal direction is arranged between the plurality of support plates 3. The purlin 4 is arranged above the support plates 3, and the support plates 3 are used to support the purlin 4. A steel support plate 3 is welded on every three pile support plates 1 to ensure that a stable lifting and supporting structure is formed for the purlin 4.

[0031] The support plate 3 is a triangular plate armor with a right angle, preferably a steel plate. One right angle side of the triangular plate armor is welded to the pile support surface 2, and a purlin 4 is provided on the other right angle side of the triangular plate armor. The other right angle side is used to achieve the fitting placement of the purlin 4 to ensure the stability of the purlin 4.

[0032] The purlin 4 is H-shaped steel, preferably Q355 material, and the H-shaped structure of the purlin 4 is erected on the support plate 3, so that the left wing plate of the purlin 4 fits the inner side of the pile support surface 2 to ensure a good force-bearing surface during support. The purlin 4 is welded to the support plate 3 and fixed by spot welding using E43 welding rods.

[0033] The purlins 4 are arranged along the longitudinal direction of the grooves, and are divided into several sections. The two adjacent sections of the purlins 4 may be fixed or not. If fixed, the end of each section of the purlin 4 is welded and fixed with an end plate armor 401, and the end plates armor 401 of the two adjacent sections of the purlins 4 are connected by bolt armor 402 to achieve splicing and extension between the two adjacent sections of the purlins 4. The purlins 4 of several sections are finally spliced ​​into a full-length support structure to act on the pile support surface.

[0034] A counter pressure plate 5 is welded and fixed on the inner side of the pile support surface 2, and the counter pressure plate 5 is clamped above the surrounding purlin 4, so that the surrounding purlin 4 is restricted up and down, ensuring that the surrounding purlin 4 is always located between the support plate 3 and the counter pressure plate 5. Even if the pile support surface 2 is tilted or settled, the surrounding purlin 4 can still ensure accurate support and cannot deform or slip. Preferably, the counter pressure plate 5 is welded and fixed on the surrounding purlin 4 to enhance the connection between the counter pressure plate 5 and the surrounding purlin 4.

[0035] The back pressure plate 5 is a right-angled triangular plate B, preferably a steel plate. One right-angled side of the triangular plate B is welded to the pile support surface 2, and the other right-angled side of the triangular plate B is used to clamp the surrounding purlin 4. The other right-angled side is used to form a limiting surface for clamping the surrounding purlin 4, and the other right-angled side can also be used to form a welding fixed relationship.

[0036] A laterally arranged support rod 6 is provided between the purlins 4 on both sides. The support rod 6 is an H-shaped steel, preferably made of Q355 material. The support rod 6 is used to form a supporting effect between the purlins 4 on both sides, so that the internal pressure formed by the soil on both sides offsets each other on the support rod 6.

[0037] An end plate B 601 is welded and fixed to the end of the support rod 6, and the end plate B 601 is connected to the surrounding purlin 4 through bolts B 602, so that the support rod 6 and the surrounding purlin 4 can be detachably fixed, which is convenient for disassembly after subsequent construction is completed.

[0038] A drainage pipeline 7 , an electric pipeline 8 and a base 9 are constructed between the opposite pile support surfaces 2 . The drainage pipeline 7 is located on the base 9 , and the electric pipeline 8 is located on the inner side of the pile support surface 2 .
