Description

Technical Field

[0001] The utility model relates to the technical field of outdoor pipe network construction of buildings, in particular to an anti-collapse protection device used in the construction process of outdoor pipe network of buildings. Background Art

[0002] In order to protect outdoor pipelines (such as water pipes and natural gas pipes) from various natural environmental tests such as earthquakes, storms, and floods, it is necessary to dig trenches at the pipeline laying site and bury the pipelines in the trenches. The trench connection can ensure the stability of the pipelines and prevent them from breaking or shifting due to natural disasters.

[0003] At present, in order to ensure the stability of the pipeline, the depth of trench excavation needs to be between 2 meters and 3 meters. However, during the trench opening process, the trench may easily collapse due to loose soil or improper trenching methods.

[0004] In order to avoid collapse during trench excavation in the prior art, supports need to be installed at the trench excavation location. The supports can ensure the stability of the trench in depth, width and longitudinal direction, and prevent the occurrence of collapse accidents. In the prior art, due to the different pre-buried depths of different pipelines, trenches of different depths need to be excavated. In order to prevent the trench from collapsing during the excavation process (areas with high water content in the soil or areas with loose soil are prone to collapse when excavating trenches), supports need to be used to shield both sides of the trench. However, the height of existing supports is generally between 1.5 meters and 2 meters. When the excavation depth exceeds the height of the support, the outer wall of the support cannot completely cover the inner wall of the trench. The exposed part of the trench is prone to collapse, which is easy to cause harm to on-site construction personnel and is not conducive to the progress of trench construction work. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides an anti-collapse protection device for use in the construction process of an outdoor pipe network of a building, aiming to solve the problems in the prior art.

A limit bolt can be removably installed in the inner cavity of the mounting hole, and a reinforcement for improving the stability of the baffle is provided on the outside of the support plate.

[0010] As a further description of the above technical solution:

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-6 The present invention provides an embodiment of a device for preventing collapse during the construction of an outdoor pipe network of a building, comprising:

[0032] The two support plates 1 are detachably provided with a supporter 7 for supporting themselves. Four supporters 7 are symmetrically installed between the two support plates 1. The four supporters 7 are composed of a two-section threaded barrel. A threaded column is installed between the two-section threaded barrels through threaded cooperation. The distance between two adjacent threaded barrels can be adjusted by rotating the threaded column, thereby adjusting the distance between the two support plates 1 and limiting the adjusted support plates 1. This is beneficial for supporting both sides of the trench through the two support plates 1 to prevent collapse during trench excavation (this is a prior art and will not be elaborated on here).

[0033] The baffle 2 is detachably mounted just above the support plate 1. A connecting block 3 is fixedly mounted on the side of the support plate 1 close to the support 7. A limiting plate 6 is fixedly mounted on the side of the baffle 2 close to the support 7. A receiving groove that matches the limiting plate 6 is provided on the top of the connecting block 3. The limiting plate 6 is set to an L-shaped structure. When the baffle 2 is mounted on the top of the support plate 1, the end of the limiting plate 6 away from the baffle 2 is inserted into the inner cavity of the receiving groove, thereby realizing the preliminary connection between the baffle 2 and the support plate 1.

[0034] When the top of the support plate 1 is in contact with the bottom of the baffle 2, the end of the limit plate 6 away from the baffle 2 is in contact with the inner wall of the accommodating groove away from its own open end. At this time, the middle of the open end of the threaded hole and the middle of the open end of the mounting hole are at the same horizontal line. Then insert the small head end of the limit bolt into the mounting hole until the small head end of the limit bolt is inserted into the threaded hole, and continue to rotate the large head end of the limit bolt until the large head end of the limit bolt is in contact with the outer wall of the connecting block 3, thereby realizing the fixed connection between the connecting block 3 and the limit plate 6. By completely fitting the side wall of the groove by the support plate 1 and the baffle 2, collapse during the trench excavation process is avoided, and harm to on-site construction personnel is prevented, which is beneficial to the trench construction work.

[0035] The outside of the support plate 1 is provided with a reinforcement for improving the stability of the baffle 2. The reinforcement includes a column 4 and a slider 12. The columns 4 are fixedly installed on both sides of the support plate 1. Sliding grooves are opened on both sides of the baffle 2 in the vertical direction. The slider 12 is slidably installed in the inner cavity of the sliding groove. The slider 12 can slide up and down along the sliding groove, thereby limiting the sliding trajectory of the slider 12.

[0036] The slider 12 is fixedly installed with a limit column 5 at one end near the open end of the sliding groove, wherein a connecting tube 11 is detachably installed between the two adjacent limit columns 5 and the column 4, and a threaded rod 9 is provided in the inner cavity of the connecting tube 11. The inner wall of the connecting tube 11 is provided with a threaded groove adapted to the threaded rod 9. The top of the threaded rod 9 and the end of the connecting tube 11 away from the threaded rod 9 are both rotatably installed with a limit ring 8. When the limit plate 6 and the connecting block 3 are connected by the limit bolts, one of the limit rings 8 is sleeved on the outside of the column 4, and then the other limit ring 8 is sleeved on the adjacent limit column 5. On the outside, the threaded rod 9 is then rotated, and with the cooperation of the threaded groove, the threaded rod 9 can be moved downward. When the threaded rod 9 moves downward, the limiting ring 8 knotted on the outside of the column 4 generates a large downward pressure on the column 4. At the same time, the limiting ring 8 knotted on the outside of the limiting column 5 moves downward with the threaded rod 9. At this time, the slider 12 moves downward along the sliding groove until the bottom of the slider 12 fits with the bottom of the inner cavity of the sliding groove and generates pressure on the bottom of the sliding groove. Stop rotating the threaded rod 9, and the same downward pressure can be applied to both sides of the baffle 2 at the same time, thereby increasing the stability of the connection between the baffle 2 and the support plate 1.

[0037] The length of the connecting tube 11 is not greater than that of the threaded rod 9 , so that the top of the threaded rod 9 can extend to the outside of the connecting tube 11 , thereby adjusting the moving distance of the threaded rod 9 .

[0038] The outer wall of the threaded rod 9 is fixedly sleeved with a driving ring 10, and the outer wall of the driving ring 10 is fixedly installed with multiple toggle columns distributed in a ring shape. When the threaded rod 9 is rotated, the threaded rod 9 can be rotated together with the driving ring 10 by toggling the toggle columns, thereby improving the convenience of rotating the threaded rod 9.

[0039] During the trench opening process, if the soil is relatively moist, it is more likely to collapse after absorbing water, and the weight of the soil increases after absorbing water. Since the baffle 2 is only supported by the limit plate 6, the supporting force is relatively small. After the collapsed soil squeezes the outer wall of the baffle 2, the baffle 2 is likely to tilt toward the inside of the trench. At the same time, the limit plate 6 tilts together with the baffle 2 and generates a large thrust on the inner wall of the accommodating groove. When the limit plate 6 is squeezed by the inner wall of the accommodating groove for a long time, it is easy to cause the limit plate 6 to deform, so that one end of the limit plate 6 can no longer be inserted into the interior of the accommodating groove, making it impossible for the baffle 2 and the support plate 1 to be connected here.

[0040] In order to solve the above technical problems, multiple supports 7 are installed between the two baffles 2. Four supports 7 are evenly installed between the two baffles 2 through bolts. The four supports 7 can simultaneously apply pressure perpendicular to the side wall of the trench to the two baffles 2 to prevent the baffles 2 from tilting when subjected to the pressure of the side wall of the trench. This situation is suitable for soil with a large trench depth or high soil humidity that causes serious landslides.

[0041] The four supports 7 between the two support plates 1 and the two baffles 2 are distributed at the edges on both sides with their middle parts as the symmetrical center. Construction workers or the excavation end of the excavation equipment can enter the bottom of the trench through two horizontally adjacent supports 7 and excavate the bottom of the trench, which is conducive to the excavation of the bottom of the trench.

[0042] In a further embodiment, the slider 12 is fixedly connected to the side of the baffle 2. When the threaded rod 9 connects the baffle 2 and the support plate 1 together, since the slider 12 cannot slide, the position between the baffle 2 and the support plate 1 can be relatively fixed, making the placement of the baffle 2 more stable.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
