Description

Technical Field

[0001] The present application relates to the field of municipal engineering technology, and more specifically, to a drainage pipe trench excavation support device. Background Art

[0002] In order to reduce expenditure and improve the appearance of the city, municipal engineering projects often take renovation measures for old residential areas. However, in the process of old city renovation, it is necessary to avoid underground facilities while minimizing the impact on ground facilities. The construction party often adopts steel sheet pile support or slope support measures for the excavation of road drainage pipeline trenches.

[0003] The document with the prior art disclosure (announcement) number CN117266187A provides a supporting device and construction method for excavating trenches of urban road drainage pipes. In the related technology of the device, the support plate and the support tube mutually constitute a finished supporting device, which can be prefabricated in the factory and recycled to improve the construction quality and efficiency. The support tube is a telescopic structure, which is convenient for adjusting the width of the support plate and is suitable for the construction of trenches of various widths. It has a wide range of applicability. The adjustable support can adjust the support plate to be close to the trench wall, and the lifting ring is conducive to lifting and disassembling the support plate.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the support tube of the telescopic structure in the device is extended and limited by a fixed pin, and when the support component is adjusted to push the two support plates to adjust the spacing, it cannot ensure that the spacing between the two extended support plates meets the fixed pin insertion and limiting use requirements after the support tube is extended, which can easily cause the support device in the groove to be installed in an unstable manner.

[0005] In view of this, we propose a drainage pipe trench excavation support device. Utility Model Content

[0006] In order to improve the problems raised in the above background technology, the present application provides a drainage pipe trench excavation support device.

[0021] As an optional solution to the technical solution of the present application document, both ends of the sliding column seat are provided with scale grooves, and the scale grooves are impregnated with eye-catching paint.

[0022] By adopting the above technical solution and marking the scale groove with eye-catching paint, it is easy to identify the expansion and contraction width of the steel pipe, thereby improving the accuracy of the use of the two steel plates.

[0023] As an optional solution of the technical solution of the present application document, the expansion support rod is composed of a tube body and docking buckets with limited insertion at both ends thereof, and the docking bucket is fixedly connected to the tube body by bolts.

[0024] By adopting the above technical solution, the expansion rod is formed by fixing the docking bucket and the pipe body with bolts, so that the pipe body in the expansion rod of the assembled structure can be easily replaced at a later stage.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] Steel plate 1;

[0036] The channel steel 2 is tightly welded to one side of the steel plate 1 in a cross structure;

[0037] The steel pipe 3 is welded tightly inside the channel steel 2 in an equidistant structure;

[0038] A sliding column seat 4 is slidably connected between two adjacent steel pipes 3;

[0039] The bidirectional lead screw 5 is rotatably connected to one end of the slide column seat 4, and two adjacent bidirectional lead screws 5 are plug-fitted and adapted;

[0040] The lead screw sleeve 6 is symmetrically threadedly connected to the outside of the bidirectional lead screw 5;

[0041] The expansion rod 7 is hingedly mounted on the outside of the screw sleeve 6 in a symmetrical structure, and the other end is hingedly mounted on the steel pipe 3.

[0042] The drainage pipe trench excavation support device uses an auxiliary tool to synchronously drive two bidirectional lead screws 5 to rotate, and the rotating bidirectional lead screw 5 pushes the lead screw sleeve 6 adapted to the external thread to pull the hinged expansion rod 7 to perform a contraction and expansion action, so that the expansion rod 7 in the contraction and expansion action pulls the two steel plates 1 to adjust the spacing to fit the side wall of the trench, thereby achieving a flexible adjustment effect of the spacing of the support device, and the contraction and expansion expansion rod 7 can reinforce the stability of the limit between the two steel plates 1.

[0043] Reference Figure 2 and Figure 1 In the drainage pipe trench excavation support device recorded in the embodiment of the present application, the steel plate 1 is made of square galvanized steel with a thickness of five millimeters and a side width diameter of three meters, the channel steel 2 is made of type 16 C galvanized steel, the steel pipe 3 is a galvanized pipe with an inner diameter of one hundred millimeters, and the expansion support rod 7 is a galvanized pipe with an inner diameter of seventy millimeters.

[0044] The drainage pipe trench excavation support device can increase the service life of steel components by utilizing a galvanizing process.

[0045] Reference Figure 3 and Figure 2 In the drainage pipe trench excavation support device recorded in the embodiment of the present application, a steel pipe 3 with an external thread groove at one end is connected to a seat cover plate 31 through external threads. The seat cover plate 31 is hingedly installed with one end of the expansion support rod 7 through an external tightly welded hinge seat, and a galvanized square tube 32 is installed on the outside of the seat cover plate 31, and the cut galvanized square tube 32 is tightly welded to the channel steel 2.

[0046] The drainage pipe trench excavation support device can realize the assembled installation of the steel pipe 3 by inserting and installing the seat cover plate 31 and the galvanized square pipe 32, which is convenient for the quick replacement of the damaged steel pipe 3 at a later time, and the galvanized square pipe 32 can be welded and reinforced at the connection of the channel steel 2, thereby ensuring the stability of the channel steel 2 in use.

[0047] Reference Figure 2 and Figure 1 In the drainage pipe trench excavation support device recorded in the embodiment of the present application, both ends of the sliding column seat 4 are provided with scale grooves, and the scale grooves are impregnated with eye-catching paint.

[0051] Working principle: When the device is needed to support and prevent collapse of the excavated trench, multiple operators use auxiliary tools to synchronously rotate the bidirectional screw 5. At this time, the rotating bidirectional screw 5 pushes the screw sleeve 6 with external thread adaptation to push the hinged expansion rod 7 to limit the extension, and push the steel plate 1 to adjust the spacing, so as to fit the side wall of the excavated trench;

[0052] Then, by observing the scale marks exposed between the sliding column seat 4 and the steel pipe 3, if the width error between the upper and lower steel plates 1 is large, continue to rotate the bidirectional screw 5 through the auxiliary tool to expand the steel plate 1 by the expansion rod 7 to ensure that the distance between the upper and lower steel plates 1 is within the error support use range.
