[0040] To make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other arbitrarily without conflict.

[0041] like Figure 1-Figure 7 An embodiment of the present invention is shown, in which a universal bracket for a direct-buried pipe is disclosed, including a receiving seat 1, on which a cylindrical receiving column 2 is vertically arranged, and the side wall of the receiving column 2 is provided with a plurality of supporting notches 3, and the upper ends of the supporting notches 3 extend to the top surface of the receiving column 2 and are connected to the outside, and the plurality of supporting notches 3 are respectively arranged in the vertical direction, and the plurality of supporting notches 3 are arranged at equal intervals along the circumference of the receiving column 2.

[0042] In one embodiment, Figure 1 , Figure 2 As shown, the direct-buried pipeline universal bracket also includes a plurality of positioning blocks 4 and support blocks 5, and the side walls of each support block 5 are horizontally provided with support arms 6, and the positioning blocks 4 and support blocks 5 can be inserted into any support notch 3, that is, a plurality of positioning blocks 4 and support blocks 5 can be stacked and inserted into the corresponding support notch 3, so that the support arms 6 are located at the elevation position of the direct-buried pipeline and are used to support the direct-buried pipeline at the corresponding layer.

[0043] The direct-buried pipeline universal bracket in this embodiment can support the direct-buried pipeline, reduce the risk of settlement or displacement of the direct-buried pipeline after operation, thereby reducing the risk of mutual pushing between two adjacent layers of pipelines, and reducing the risk of water leakage and air leakage in the pipeline, thereby avoiding engineering quality accidents.

[0044] In this embodiment, if the pipelines are arranged in parallel, multiple support blocks 5 and positioning blocks 4 are located in the same support notch 3; if the pipelines are arranged crosswise, multiple support blocks 5 and positioning blocks 4 are located in two adjacent support notches 3, so that the direct-buried pipeline universal bracket can adapt to parallel or cross-buried direct-buried pipelines. Specific examples are described in detail in the method of using the direct-buried pipeline universal bracket.

[0045] In this embodiment, there are four support notches 3, and the four support notches 3 are arranged at 90° intervals. Of course, in other embodiments, there can be six support notches 3, and the six support notches 3 are arranged at 60° intervals. Other numbers are also possible, which are not listed in detail here.

[0046] In one embodiment, Figure 1 , Figure 2 As shown, the positioning block 4 includes a dovetail portion 41 and a fan-shaped portion 42 integrally formed, and when the positioning block 4 is inserted into the support notch 3, the fan-shaped portion 42 of the positioning block 4 is located at the edge of the receiving column 2. At the same time, the support block 5 has the same outer contour as the dovetail portion 41 of the positioning block 4, and the inner side wall of the support notch 3 matches the outer contour of the positioning block 4, so that the positioning block 4 and the support block 5 can be tightly inserted into the support notch 3.

[0047] Since the outer contours of the positioning block 4 and the support block 5 are composed of multiple surfaces, and the positioning block 4 and the support block 5 can cooperate with the support notch 3, when the positioning block 4 and the support block 5 are inserted into the support notch 3, the horizontal position limitation can be automatically achieved. At the same time, this design can also achieve the support of the support arm 6, that is, the support block 5 is inserted into the support notch 3, and the support block 5 cannot be twisted in the vertical direction, so that the support arm 6 can maintain a horizontal state and has a good supporting effect on the support arm 6.

[0048] In one embodiment, Figure 1 , Figure 2 As shown, a circular arc surface 43 is integrally formed on the fan-shaped portion 42 of the positioning block 4. When the positioning block 4 is inserted into the supporting notch 3, the circular arc surface 43 is flush with the outer surface of the receiving column 2, thereby avoiding the problem of interference between the positioning block 4 and the directly buried pipeline and improving the aesthetics.

[0049] In one embodiment, Figure 1 , Figure 2 As shown, the support arm 6 is integrally connected with the corresponding support block 5 to improve the structural strength between the two, thereby improving the stability of the bracket. At the same time, the thickness of the support arm 6, the support block 5 and the positioning block 4 is the same, so that the staff can easily select the number of positioning blocks 4.

[0050] In one embodiment, Figure 1 , Figure 2 As shown, when multiple positioning blocks 4 and supporting blocks 5 are stacked and inserted into corresponding supporting notches 3 respectively, the gaps between the positioning blocks 4 and the gaps between the positioning blocks 4 and the supporting blocks 5 are grouted respectively, so that the multiple positioning blocks 4 and supporting blocks 5 are connected as a whole to improve the structural stability.

[0051] In one embodiment, Figure 1 , Figure 2 , Figure 3 As shown, a mounting groove 7 is provided on the upper surface of the receiving seat 1, the bottom of the receiving column 2 is tightly inserted into the mounting groove 7, and the receiving column 2 and the receiving seat 1 are sealed and fixed by grouting, that is, grouting is performed in the mounting groove 7 to achieve the connection between the receiving column 2 and the receiving seat 1.

[0052] In one embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the receiving seat 1 includes a truncated pedestal seat 11 and a cylindrical seat 12. The diameter of the upper surface of the truncated pedestal seat 11 is smaller than the diameter of its lower surface. The diameter of the cylindrical seat 12 is the same as the diameter of the upper surface of the truncated pedestal seat 11. The cylindrical seat 12 is integrally formed and connected to the top of the truncated pedestal seat 11 to improve the limiting effect between the receiving seat 1 and the formation and reduce the risk of settlement of the receiving seat 1.

[0053] This embodiment also discloses a method for using the universal bracket for direct buried pipelines, comprising the following steps:

[0054] S1, a receiving groove matching the outer contour of the receiving seat 1 is dug in the pipeline pit, concrete is poured into the receiving groove, and a mounting groove 7 is reserved, and the receiving seat 1 can be formed after the concrete is solidified. Subsequently, the bottom of the receiving column 2 is inserted into the mounting groove 7, and the mounting groove 7 is grouting to achieve the connection and sealing between the receiving column 2 and the receiving seat 1.

[0055] S2. Calibrate the position on the support column according to the elevation of the direct buried pipeline.

[0056] S3, according to the positional relationship of the direct buried pipeline and the calibrated height of the support column, select the correct number of positioning blocks 4 and support blocks 5, and insert the positioning blocks 4 and support blocks 5 into the corresponding support notches 3 respectively, and ensure that the support arm 6 is located at the calibrated position of the support column.

[0057] S4, grouting is performed respectively on the gap between two positioning blocks 4 and the gap between the positioning block 4 and the supporting block 5 to connect the multiple positioning blocks 4 and the supporting block 5 as a whole. Of course, grouting can also be performed on the supporting gap 3 to connect the receiving column 2, the positioning block 4 and the supporting block 5 as a whole.

[0058] S5, installing the direct buried pipeline and making the direct buried pipeline abut against the upper surface of the corresponding support arm 6;

[0059] S6, observe whether the bracket is stable. If the bracket is stable, fill the pipeline foundation pit.

[0060] In order to more clearly illustrate this embodiment, the specific examples are as follows:

[0061] like Figure 4 , Figure 5As shown, if two direct buried pipelines are arranged in parallel, the thickness of the positioning block 4 and the support block 5 are 10 cm respectively, the elevation of the lower direct buried pipeline is 40 cm, and the elevation of the upper direct buried pipeline is 90 cm, that is, the spacing between the two direct buried pipelines is 50 cm, then two support blocks 5 and seven positioning blocks 4 are selected. Three of the positioning blocks 4 are respectively inserted into the corresponding support gaps 3, and then one support block 5 is inserted into the support gap 3. At this time, the position of the support arm 6 is consistent with the elevation of the lower direct buried pipeline. Subsequently, the remaining four positioning blocks 4 are inserted into the support gap 3, and then another support block 5 is inserted into the support gap 3. At this time, the position of the support arm 6 is consistent with the elevation of the upper direct buried pipeline. After the two direct buried pipelines are installed, the two direct buried pipelines are respectively placed on the corresponding support arms 6, that is, the two support arms 6 are used to support the two parallel direct buried pipelines.

[0062] like Figure 6 , Figure 7 As shown, if two directly buried pipelines are cross-set, the thickness of the positioning block 4 and the support block 5 are 10 cm respectively, the elevation of the lower layer of the direct buried pipeline is 40 cm, and the elevation of the upper layer of the direct buried pipeline is 90 cm, that is, the spacing between the two directly buried pipelines is 50 cm, then two support blocks 5 and eleven positioning blocks 4 are selected. Three of the positioning blocks 4 are respectively inserted into the corresponding support gaps 3, and then one support block 5 is inserted into the support gap 3. At this time, the position of the support arm 6 is consistent with the elevation of the lower layer of the direct buried pipeline. Subsequently, the remaining eight positioning blocks 4 are inserted into the support gaps 3 at adjacent positions, and then another support block 5 is inserted into the support gap 3. At this time, the position of the support arm 6 is consistent with the elevation of the upper layer of the direct buried pipeline. After the two directly buried pipelines are installed, the two directly buried pipelines are respectively placed on the corresponding support arms 6, that is, the two support arms 6 are used to support the two cross-set direct buried pipelines respectively.

[0063] Of course, if there are three directly buried pipes, and the three are arranged in parallel, or two adjacent pipes are arranged crosswise, the above method can be used to select a corresponding number of support blocks 5 and positioning blocks 4, and insert the support blocks 5 and positioning blocks 4 into the corresponding support notches 3, and support the directly buried pipes in the corresponding layers through the support arms 6.

[0064] From the above, it can be seen that the direct buried pipeline universal bracket solves the protection problem of crossed pipelines and parallel pipelines. It can effectively isolate the upper pipeline and the lower pipeline at the main cross-node to prevent the upper and lower pipelines from being pushed up and other problems.

[0065] At the same time, this design makes the upper and lower pipelines locally stable at the planned design elevation, preventing the upper pipeline at the intersection from being affected by the upper traffic and causing settlement problems. It can also reduce the settlement problems caused by large burial depth, uneven backfill and insufficient compaction, and achieves local reinforcement for the lower pipeline to prevent settlement of the lower pipeline.

[0066] Not only that, this design adopts prefabricated methods for construction and adjustment, which can effectively deal with problems caused by changes in pipeline slope, on-site adjustments, renovation projects, etc., speed up the construction progress, and minimize the impact on the people during the construction of municipal engineering projects.
