Description

Technical Field

[0001] The utility model belongs to the field of municipal construction, and more specifically, particularly relates to a foundation pit enclosure. Background Art

[0002] The foundation pit enclosure is a kind of safety fence facility used to protect the foundation pit construction site. It can effectively shield and isolate the construction site from the external environment, prevent external personnel and debris from falling into the building foundation pit, not only prevent the occurrence of foundation pit construction accidents, but also can well enhance the image of civilized construction in the city. At present, traditional foundation pit enclosures mostly use fixed triangular brackets to vertically fix and support the steel vertical plates. Each set of steel vertical plates are connected by multiple sets of bolts. It can be seen that the traditional foundation pit enclosure only uses steel vertical plates to shield and separate the internal and external spaces of the foundation pit construction site. A large amount of sand and dust generated by the construction inside the foundation pit will be blown from the top of the vertical plate to the outside with the air flow, causing sand and dust pollution to the external environment of the construction site. In addition, the multiple sets of vertical plates of the foundation pit enclosure are connected by bolts, which makes the installation process complicated and cumbersome, and is not convenient for the later dismantling and recycling of the enclosure.

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1-8 As shown, the utility model provides a foundation pit enclosure, including a flexible pipe 1; the left and right ends of the flexible pipe 1 are both screwed with water pipes 8; it also includes a baffle 5, a sound insulation pad 11 and a return spring 15; the rear side of the baffle 5 is connected to a magnetic block 7 by bolts near the bottom end, the front side of the baffle 5 is adhered with a reflective sticker 12, the rear side of the baffle 5 is connected to a silencer 6 by bolts, the rear side of the baffle 5 is hinged to a support frame 4 near the left and right ends, the bottom end of the support frame 4 is provided with a convex plate, the convex plate is provided with a through hole, and the upper side of the baffle 5 is connected to the top by bolts The baffle 2, a water pipe 8 is installed on the upper side of the top baffle 2 near the rear end, and an atomizing nozzle 9 is installed on the outer side of the water pipe 8. The left side of the baffle 5 is hinged with a locking plate 10, and the right side of the baffle 5 is hinged with a connecting plate 3. The right side of the connecting plate 3 is provided with two groups of ear plate structures from top to bottom, and each group of ear plates is provided with a through hole. The baffle 5 is bonded to the sound insulation cotton pad 11; the top end of the return spring 15 is welded to the locking plate 10, and the bottom end of the return spring 15 is welded to the locking rod 13, and the middle part of the outer side of the locking rod 13 is welded to the push rod 14.

[0024] In the disclosed embodiment, the silencer 6 is a rectangular plate structure, which covers the rear side of the baffle 5. The surface of the silencer 6 is densely covered with a large number of through-hole structures. Through the through-hole structure of the silencer 6, the air medium that transmits sound generates resistance by friction in the hole, thereby consuming sound energy, effectively reducing the impact of noise such as steel bar cutting inside the construction site on the outside of the construction site, and reducing construction noise pollution.

[0025] In the disclosed embodiment, seven groups of through holes are provided on the outer side surface of the water pipe 8 facing the rear end, and seven groups of atomizing nozzles 9 are respectively installed in the seven groups of through holes of the water pipe 8, so that the water flowing into the water pipe 8 flows to the atomizing nozzles 9 through the through holes, and finally the water body is diffused and sprayed out from the atomizing nozzles 9 in the form of mist, thereby moistening the dust-laden air flowing through the top of the baffle 5 and preventing sand and dust from leaking into the environment outside the foundation pit construction site.

[0026] In the disclosed embodiment, the top shield 2 adopts an arc-shaped bent plate structure, and the arc-shaped folded plate structure of the top shield 2 bends toward the rear side, changing the airflow direction of the dust-laden air and reducing the leakage of sand and dust from the top of the baffle 5.

[0027] In the embodiment of the present disclosure, two groups of insertion rods are provided on the outer side surface of the locking rod 13 facing the left end, and each group of insertion rods is an inverted J-shaped structure. The two groups of insertion rods of the locking rod 13 are respectively inserted into the two groups of ear plate through holes of the connecting plate 3, and the locking rod 13 is plugged and locked to the connecting plate 3. A ring plate is provided on the outer side surface of the locking rod 13 near the top, and a return spring 15 is welded to the upper side surface of the ring plate. The return spring 15 pushes the ring plate to move downward, and the return spring 15 drives the locking rod 13 to be inserted into the ear plate through hole of the connecting plate 3 through the ring plate and is pushed and locked to the upper limit by the elastic force of the return spring 15, so as to prevent the J-shaped insertion rod of the locking rod 13 from being disengaged from the ear plate through hole of the connecting plate 3 due to severe external vibration, resulting in failure of the combined connection of the two groups of baffles 5.

[0028] In the embodiment of the present disclosure, the interior of the locking plate 10 is hollow, and the locking rod 13 is embedded in the interior of the locking plate 10. A through hole is provided on the upper side of the locking plate 10, and the top of the locking rod 13 is inserted into the through hole on the upper side of the locking plate 10. The left side of the locking plate 10 is provided with two groups of small through grooves that pass through the left and right sides, and the rear side of the locking plate 10 is provided with a long through groove. The push rod 14 is inserted into the long through groove of the locking plate 10, and the outer side of the push rod 14 is attached to the left and right groove walls of the long through groove of the locking plate 10. The push rod 14 drives the welded locking rod 13 to move vertically up and down to ensure that the J-shaped insertion rod of the locking rod 13 is accurately and stably inserted into the ear plate through hole of the connecting plate 3.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When the utility model is carrying out the construction of the foundation pit enclosure, the support frame 4 is first flipped backward and unfolded, and then the rivet is inserted into the convex plate through hole of the support frame 4, and the rivet is driven into the ground with a hammer, and then the locking rod 13 is manually pushed to overcome the elastic force of the spring and lifted upward, and then the ear plate of the other set of connecting plates 3 of the foundation pit enclosure is inserted into the through groove on the left side of the locking plate 10. At this time, the ear plate through hole of the connecting plate 3 is opposite to the insertion rod of the locking rod 13 up and down, and then the push rod 14 is released, and the push rod 14 moves vertically downward along the long through groove on the rear side of the locking plate 10, and the push rod 14 drives the insertion rod on the outer side of the locking rod 13 to move vertically downward until the two groups of insertion rods of the locking rod 13 are connected. The two groups of foundation pit enclosure assembly and construction are completed in the two groups of ear plate through holes of the connecting plate 3. If dismantling is required, manually push the push rod 14 upward, and the push rod 14 drives the insertion rod of the locking rod 13 to disengage from the two groups of ear plate through holes of the connecting plate 3. Then move the connecting plate 3 to the left to disengage from the through groove on the left side of the locking plate 10. When performing the dust reduction work of the foundation pit enclosure, install the external water pipe at any one of the left and right ends of the water pipe 8, and the other end of the water pipe 8 is connected in series with another group of water pipes 8 through the flexible pipe 1. The water from the external water pipe flows into the water pipe 8, and then flows into the atomizing nozzle 9 from the through hole of the water pipe 8 and is sprayed in the form of mist, completing the water mist dust reduction work of the air dust.

[0031] All of the above components are installed, connected, or configured using common mechanical methods, such as welding, threaded connections, and screw connections. The specific structures, models, and coefficients of all components are proprietary technologies, and any method that can achieve the desired effect may be implemented.
