Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and more specifically, to a road surface foundation pit enclosure structure based on road construction. Background Art

[0002] During the road construction process, the roadbed is not only the main body of the route, but also the foundation of the road surface and bears the vehicle load together with the road surface. The roadbed is divided into three categories according to the filling and excavation conditions of its cross-section: embankment type, cutting type and semi-filled and semi-excavated type. During the road construction process, the road foundation pit usually needs to be enclosed by a retaining structure to prevent pedestrians or vehicles from falling into the foundation pit and causing casualties.

[0003] Patent CN111636762A discloses a road foundation pit enclosure structure for road construction, which is a rectangular through hole opened by a rectangular plate, so that air can flow through the rectangular through hole to prevent the device from being blown down by wind. When there is no wind, the rectangular through hole is sealed by the rectangular plate, and warning slogans can be sprayed on the baffle plate and the rectangular plate for pedestrians to see; However, the above-mentioned patent document only has the function of setting an openable through hole on the enclosure structure to release wind pressure, but in actual use, there is no structure to buffer and utilize the wind force, which results in the enclosure plate still being passively forced by the wind and being unable to use the wind force to reversely relieve the pressure and maintain a stable state. At the same time, there is no structure to block and intercept the dust blown by the wind. During the wind blowing process, the through holes allow the wind carrying dust to pass directly, which can easily cause the construction environment to be affected by wind and sand.

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: In view of the fact that the prior art does not have a structure to buffer and utilize wind force, which results in the enclosure plate still being passively stressed by the wind and unable to relieve the pressure in the opposite direction with the help of wind force to maintain a stable state, the following technical solution is proposed to solve this problem: Refer to the instruction manual Figure 1-Figure 7 , based on the road construction pavement foundation pit enclosure structure, such as Figure 1 and Figure 2 As shown, it comprises a base 1, a guardrail frame 2 is fixedly installed on the top of the base 1, and a guide mechanism 3 and a sealing mechanism 4 are arranged on the outer wall of the guardrail frame 2; like Figure 3 As shown, the guide mechanism 3 includes a plurality of baffle plates 31 arranged on the inner wall of the guardrail frame 2, the plurality of baffle plates 31 are arranged in a vertical state, the outer walls of the plurality of baffle plates 31 are in contact with the inner wall of the guardrail frame 2, a rotating rod 32 is rotatably installed at the bottom of the plurality of baffle plates 31, the rotating rod 32 is fixedly installed on the inner wall of the base 1, a weight-pull rod 33 is fixedly installed at the bottom of the plurality of baffle plates 31, the weight-pull rod 33 is arranged in a horizontal state, the weight-pull rod 33 is located inside the base 1, and the baffle plates 31 are driven to remain vertical by the weight-pull rod 33. When the baffle plates 31 are blown by the wind, the weight-pull rod 33 is driven to rotate on the rotating rod 32 by the baffle plates 31.

[0020] like Figure 3 and Figure 4 As shown, a plurality of panel frames 34 are respectively provided on both sides of the baffle plates 31, and the plurality of panel frames 34 are fixedly mounted on the outer wall of the fence frame 2, and the outer walls of the plurality of panel frames 34 are arranged in an inclined state, and the plurality of panel frames 34 are arranged symmetrically with each other, and the plurality of panel frames 34 are arranged symmetrically with each other in pairs, and the outer walls of the plurality of panel frames 34 correspond to the outer walls of the baffle plates 31, and a limiting plate 35 is fixedly mounted on one side of the plurality of panel frames 34, and the limiting plate 35 and the panel frames 34 are arranged perpendicularly to each other, and the limiting plate 35 and the baffle plates 31 are arranged corresponding to each other, then the wind blows the baffle plates 31 to one side and approaches the panel frames 34 on the same side, and the baffle plates 31 are kept in an inclined state through the panel frames 34 and the limiting plates 35, then the wind passes through the baffle plates 31 and causes the airflow to blow upward.

[0021] like Figure 3 and Figure 5 As shown, an air collecting groove 36 is fixedly installed on the top of the multiple panel frames 34, and the air collecting groove 36 is fixedly installed on the outer wall of the guardrail frame 2. The air collecting groove 36 is arranged in a horizontal state. One side of the air collecting groove 36 is connected to an air guide groove 37, and the air guide groove 37 is arranged in a horizontal state. Then, the airflow passes through the baffle plate 31 upward into the air collecting groove 36 and is discharged from the air guide groove 37. At this time, since the direction of the airflow discharged from the air guide groove 37 is opposite to the direction of the wind, the pressure of the discharged airflow buffers the wind force.

[0022] like Figure 5As shown, the sealing mechanism 4 includes a rubber pad 41 fixedly mounted on the inner walls of multiple plate racks 34. The rubber pad 41 is arranged in an L shape, and one side of the rubber pad 41 is fixedly mounted on the outer wall of the limiting plate 35. The rubber pad 41 allows the enclosing plate 31 to fit tightly when it is close to the plate rack 34 and the limiting plate 35 to prevent airflow from escaping.

[0023] like Figure 2 and Figure 5 As shown, sealing plates 42 are respectively provided on the tops of both sides of the multiple baffle plates 31, and the multiple baffle plates 42 are symmetrically arranged in pairs. Pull rods 43 are respectively fixedly installed on the outer walls of the two baffle plates 42, and the pull rods 43 are slidably installed on the inner wall of the air collecting groove 36. A limiting spring 44 is fixedly installed on one side of the pull rod 43, and the limit spring 44 is fixedly installed on the outer wall of the air collecting groove 36. The baffle plates 42 are driven by the deflection of the baffle plates 31 to squeeze and drive them, and then the baffle plates 42 squeeze the pull rods 43 to stretch the limit springs 44, so that the baffle plates 42 are always in contact with the tops of the baffle plates 31, so that the gap between the baffle plates 31 and the air collecting groove 36 is connected through the baffle plates 42 to avoid air leakage.

[0024] The wind blows the airflow upward through the enclosing plate 31, and the airflow passes through the enclosing plate 31 and enters the air collecting groove 36 and is discharged from the air guide groove 37. At this time, the direction of the airflow discharged from the air guide groove 37 is opposite to the direction of the wind, and the pressure of the discharged airflow buffers the wind force.

[0025] Embodiment 2: There is no structure to block and intercept the dust blown by the wind. In the process of wind blowing, the wind carrying dust passes directly through the through hole, resulting in the construction environment being affected by the wind and sand. To solve this problem, the following technical solution is proposed: like Figure 6 and Figure 7 As shown, a pull-net dust-isolating mechanism 5 is provided on the top of the enclosing plate 31. The pull-net dust-isolating mechanism 5 includes a partition net 51 fixedly installed on the top of the enclosing plate 31. The partition net 51 is arranged in a vertical state. The length of the partition net 51 is the same as the length of the enclosing plate 31. The partition net 51 is pulled out by the deflection of the enclosing plate 31, and then the wind passing through the top of the enclosing plate 31 carries the dust through the partition net 51.

[0026] like Figure 6 and Figure 7 As shown, scraper plates 52 are respectively provided on both sides of the partition net 51. The two scraper plates 52 are fixedly installed on the inner wall of the guardrail frame 2. The outer walls of the two scraper plates 52 are in contact with the outer walls on both sides of the partition net 51. The outer wall of the moving partition net 51 is scraped by the scraper plates 52, so that the dust intercepted by the partition net 51 can be scraped off.

[0027] like Figure 6 and Figure 7 As shown, the outer wall of the partition net 51 is provided with a through groove 53, and the through groove 53 is opened on the inner wall of the guardrail frame 2. A lifting plate 54 is fixedly installed on the top of the partition net 51, and the lifting plate 54 is slidably installed on the inner wall of the through groove 53. A supporting spring 55 is fixedly installed on the top of the lifting plate 54, and the supporting spring 55 is fixedly installed on the inner wall of the guardrail frame 2. The partition net 51 is pulled by the enclosure plate 31, and then the partition net 51 moves downward, so that the lifting plate 54 moves downward in the through groove 53 synchronously, that is, the lifting plate 54 moves downward to pull the supporting spring 55 to extend.

[0028] In specific implementation, the partition net 51 is pulled out by the deflection of the enclosure plate 31, and then the partition net 51 moves downward, causing the lifting plate 54 to move downward in the through groove 53 synchronously, that is, the lifting plate 54 moves downward to pull the supporting spring 55 to extend. At this time, the wind passing through the top of the enclosure plate 31 carries the dust and passes through the partition net 51 and is blocked. After the wind stops, the supporting spring 55 on the lifting plate 54 retracts the partition net 51 and drives the enclosure plate 31 to return to the normal state, and then the outer wall of the upwardly moved partition net 51 is scraped off by the scraper plate 52, so as to facilitate the scraping off of the dust intercepted by the partition net 51.

[0029] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
