Description

Technical Field

[0001] The utility model relates to the field of earth excavation construction, in particular to a rotatable deep trench protection tool. Background Art

[0002] The most important issue in outdoor deep trench construction is the safety protection of workers when installing pipelines in the pipeline trench. In the existing trench construction excavation work, the main safety hazard in the trench construction is the collapse of the soil slopes on both sides. However, the trench construction process is often long in the longitudinal excavation length and small in the transverse excavation width, and some pipelines have been built around the buildings during construction. Due to site space limitations, sometimes the soil slopes on both sides of the trench are difficult to meet the safety factor, and safety protection is difficult to effectively construct.

[0019] The utility model is further described in detail below:

[0020] like Figures 1 to 5As shown, the utility model provides a rotatable deep groove protection tool, including a main supporting keel 1, the main supporting keel 1 includes a square steel column 11, a square steel long keel 12 and a square steel short keel 13, a total of six square steel columns 11 are arranged, the six square steel columns 11 are symmetrically arranged in two rows, the square steel long keels 12 are respectively located between the six leading square steel columns 11 and welded and fixed, the left and right sides of the main supporting keel 1 are fixedly connected with a protective patterned steel plate 2, the bottoms of the six square steel columns 11 are fixedly connected with a support base 3, and the bottom of the support base 3 is fixedly connected with an angle steel foundation 4.

[0021] The main supporting keel 1 is welded with square steel as the base material, and protective patterned steel plates 2 are welded on both sides for retaining soil. The secondary supporting keel 5 is welded on the inner side of the protective patterned steel plate 2 to ensure the structural strength. The supporting base 3 is welded under the main supporting keel 1 to avoid the settlement of the main supporting keel 1. At the same time, the angle steel foundation 4 is welded under the supporting base 3 and inserted into the soil to enhance the stability of the device and avoid the overall rollover of the main supporting keel 1. When multiple tools are vertically connected, the angle steel foundation 4 can be used in conjunction with the square steel column 11 for socket connection to ensure the connection stability. The hook 7 welded on the top can be used for overall lifting and movement. It has a simple structure, low processing cost and short cycle, and is easy to use. It effectively solves the safety hazard caused by insufficient space for slope laying during trench excavation. The rapid assembly of protective tools is achieved by adopting standardized prefabrication, with fast construction speed, low space requirement and high safety.

[0022] like Figure 2 and Figure 5 As shown, a secondary supporting keel 5 is fixedly welded to the inner side of the protective patterned steel plate 2 , and both ends of the secondary supporting keel 5 are respectively welded to the outer sides of adjacent square steel columns 11 .

[0023] The secondary supporting keels 5 are arranged at equal intervals in the longitudinal direction. The top of the square steel long keel 12 and the top of the secondary supporting keel 5 are fixedly connected with a ladder plate 6, which is arranged at a corner of the inner side of the main supporting keel 1.

[0024] The secondary support keel 5 is welded to the inner side of the protective patterned steel plate 2 and its two ends are welded to the outer side of the square steel column 11, cooperating with the main support keel 1 to ensure the overall structural strength and stability of the protective tool. The welded ladder plate 6 is arranged longitudinally for workers to go up and down.

[0025] like Figure 5 As shown, the top of the square steel long keel 12 is fixedly welded with a hook 7 arranged in a "J" shape.

[0026] The hook 7 arranged in a "J" shape on the square steel long keel 12 facilitates the overall lifting, moving and combined assembly, making it convenient to use.

[0027] like Figure 2As shown, the support base 3 is welded and fixed to the bottom of the square steel column 11 , and the angle steel foundation 4 is welded and fixed to the bottom of the support base 3 .

[0028] The support base 3 and the angle steel foundation 4 located at the bottom of the square steel column 11 are used to enhance the stability of the tool by inserting the angle steel foundation 4 into the soil, thereby preventing the overall rollover of the protective tool. The setting of the support base 3 prevents the tool from sinking.

[0029] like Figure 5 As shown, the inner diameter of the square steel column 11 is slightly larger than the outer diameter of the angle steel foundation 4 .

[0030] Since the inner diameter of the square steel column 11 is slightly larger than the outer diameter of the angle steel foundation 4 , the angle steel foundation 4 can be inserted into the square steel column 11 , which facilitates the longitudinal assembly and use of multiple protective tools.

[0031] The working principle of the turnaround deep groove protection tool is described in detail below.

[0032] like Figures 1 to 5 As shown, when used on site, after the trench is excavated, the protective tool is directly lifted into the trench by a lifting machine using the hook 7 located on the top of the long square steel keel 12. The main supporting keel 1 is used as the basic framework and the protective patterned steel plates 2 on both sides are used for retaining soil. The tool is sunk into the soil by its own weight, and the angle steel foundation 4 at the bottom of the supporting base 3 is inserted into the soil to enhance the stability of the tool and prevent the protective tool from tipping over as a whole. The supporting base 3 is used to prevent the protective tool from sinking, and the pipeline is extended into the protective tool from the lower space. Multiple protective tools are directly placed side by side when connected horizontally through the tool groove. When connected vertically, the angle steel foundation 4 at the bottom of the upper protective tool is inserted into the square steel column 11 of the lower protective tool for assembly.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
