Description

Technical Field

[0001] The utility model relates to the technical field of support devices, in particular to a transverse plate support device for inspection wells. Background Art

[0002] The operation surface of urban municipal pipe network projects is mainly located in the central urban area. The operation surface conditions are limited, the surrounding sites are narrow, and in the process of trench construction, in order to ensure operation safety and comprehensively consider the construction period, construction conditions and project cost, the traditional transverse plate support form is mostly used for trenches with a depth less than 3 meters. However, the upper opening width of the trench at the inspection well position is larger than that at the pipe position. The traditional transverse plate support system is often discontinuous due to factors such as trench width and internal support arrangement, there are support blank areas, and there are still safety risks; while the Larsen steel sheet piles used for inspection well support have high costs and long construction periods. Summary of the Invention

[0003] The technical problem to be solved by the utility model is that the traditional transverse plate support cannot meet the stable support for inspection wells.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a transverse plate support device for inspection wells, including a U-shaped transverse purlin arranged on the opposite inner side walls of the inspection well, vertical purlins vertically arranged on the opposite inner side walls of the transverse purlin, support steel pipes horizontally arranged between adjacent two vertical purlins, and transverse plates attached to the inner side walls of the inspection well and its connected pipes. The inner side wall of the transverse plate is attached to the outer side wall of the transverse purlin, and support steel pipes are horizontally arranged between the transverse plates on the opposite inner side walls of the connected pipes.

[0005] Preferably, the cross-sections of the transverse purlin and the vertical purlin are both in the shape of an I-beam, and the cavity of the vertical purlin is filled with wooden squares.

[0006] Preferably, the end of the transverse purlin is in the same plane as the inner side wall of the transverse plate on the inner side wall of the connected pipe.

[0007] Preferably, a vertical rib with a U-shaped cross-section is vertically arranged on the inner side wall of the transverse plate in the connected pipe, and the end of the support steel pipe abuts against the inner wall of the vertical rib.

[0008] Preferably, the support steel pipe includes a steel pipe in the middle, an adjustment platform threadedly connected coaxially to the end of the steel pipe, and an insertion head fixedly arranged at the end of the adjustment platform. The insertion head is located in the vertical rib.

[0009] Preferably, the insertion head is a T-shaped rotating body structure, and friction grooves are arranged on the contact wall between the insertion head and the vertical rib.

[0010] The utility model provides a transverse plate support device for inspection wells, which uses transverse plates to support inspection wells. Compared with the support of L-shaped steel sheet piles for inspection wells, the work efficiency can be increased by about 55%. The cost of steel sheet piles is calculated at a comprehensive unit price of 4,000 yuan per linear meter, and the total price is 12,000 yuan. In contrast, the transverse plate support can be calculated at 100 yuan per square meter, and the total support area is about 20 square meters, and the calculated total price is 2,000 yuan, and the cost is reduced by about 500% year-on-year.

[0011] 2. Compared with the conventional L-shaped steel sheet pile support, the construction space limitation is greatly reduced, and the influence of vibration on surrounding buildings is reduced.

[0012] 3. Since the transverse plate support of the inspection well adopts a fixed size, it avoids the interference between the support and the construction of the inspection well, and the support system is complete, which is conducive to the construction quality control and standardizes the construction.

[0013] 4. The transverse plate support is supported as it is excavated, with a high turnover rate. After backfilling, it greatly reduces the influence of pulling out other supports such as L-shaped steel sheet piles on the settlement of municipal roads. Description of the Drawings

[0018] As Figure 1 and Figure 2 shown, the utility model provides a transverse plate support device for inspection wells, which includes a U-shaped transverse purlin 2 arranged on the opposite inner side walls of the inspection well, a vertical purlin 3 vertically arranged on the opposite inner side walls of the transverse purlin 2, a support steel pipe 4 horizontally arranged between two adjacent vertical purlins 3, and a transverse plate 1 attached to the inner side walls of the inspection well and its connected pipelines. The outer side wall of the transverse purlin 2 is attached to the inner side wall of the transverse plate 1, and a support steel pipe 4 is horizontally arranged between the transverse plates 1 on the opposite inner side walls of the connected pipelines.

[0019] The horizontal cross purlin 2 is welded with I-beams. Three I-beams are welded to form a U-shaped horizontal cross purlin 2 structure. After the horizontal plates 1 are vertically arranged on the inner wall of the inspection well, the horizontal cross purlin 2 can be attached to the inner wall of the horizontal plates 1. The horizontal plates are made of 5-mm-thick steel plates for retaining soil and are arranged above the inspection well foundation 7. In addition, to ensure the stability of the installation of the horizontal cross purlin 2, steel corbels are welded on the inner wall of the horizontal plates 1 to support the horizontal cross purlin 2. The horizontal cross purlin 2 is arranged in two layers according to the support requirements of the inspection well to support both the top and bottom of the horizontal plates 1.

[0020] The vertical cross purlin 3 is arranged relying on the horizontal cross purlin 2, and the vertical cross purlin 3 is braced by the support steel pipes 4. The four support steel pipes 4 are distributed in a rectangle, leaving enough space inside the inspection well for convenient construction.

[0021] The horizontal plates 1 are arranged along the connecting pipes of the inspection well, and then the two sides of the horizontal plates 1 are supported by the support steel pipes 4 to ensure the safety of the foundation pit.

[0022] As Figure 1 and Figure 2 shown, to prevent the horizontal cross purlin 2 and the vertical cross purlin 3 from deforming. The cross-sections of the horizontal cross purlin 2 and the vertical cross purlin 3 are both I-shaped, and the cavity of the vertical cross purlin 3 is filled with wooden squares 5. The wooden squares 5 are filled in the cavities on both sides of the vertical cross purlin 3, and three outer walls of the wooden squares 5 are fitted with three inner walls of the vertical cross purlin 3. The remaining one outer wall of the wooden squares 5 is in the same plane as the outer end of the vertical cross purlin 3, and the support steel pipe 4 can stably contact the vertical cross purlin 3.

[0023] As Figure 1 shown, to prevent the horizontal cross purlin 2 from having protruding parts, eliminate the hidden danger of passage between the connecting pipe and the inspection well, and ensure the axial support of the horizontal cross purlin 2 for the horizontal plates 1 inside the connecting pipe. The end of the horizontal cross purlin 2 is in the same plane as the inner wall of the horizontal plates 1 on the inner wall of the connecting pipe.

[0024] As Figure 1 shown, to achieve the stable support of the support steel pipe 4 for the horizontal plates 1 inside the connecting pipe. The vertical ribs 6 with a U-shaped cross-section are vertically arranged on the inner wall of the horizontal plates 1 inside the connecting pipe, and the end of the support steel pipe 4 abuts against the inner wall of the vertical ribs 6. The vertical ribs 6 are made of channel steel, which can not only limit the end of the support steel pipe 4 but also provide enough contact area to ensure the bracing effect.

[0025] As Figure 1The supporting steel pipe 4 comprises a steel pipe in the middle, an adjusting platform coaxially threadedly connected to the end of the steel pipe, and an inserting head fixedly arranged at the end of the adjusting platform, and the inserting head is located in the vertical rib 6. The length of the supporting steel pipe 4 can be adjusted by rotating the adjusting platform to meet the support length requirements of the horizontal plate 1 in the inspection well or the connecting pipeline.

[0026] As a preferred embodiment of the utility model, the insertion head is a T-shaped rotating body structure, and a friction groove is provided on the contact wall between the insertion head and the vertical rib 6. When the length of the horizontal strip 1 is adjusted by rotating the adjustment table, since the insertion head adopts a rotating body structure, it can be ensured that the insertion head can always be inserted into the vertical rib 6 to achieve stable top support.
