Problems solved by technology
[0003] At present, the engineering enclosures used in municipal engineering mainly have the following defects: 1. The panels of municipal engineering construction enclosures are mostly single-layer pressed steel plates, which cannot absorb and reduce noise, and often cause noise troubles to nearby residents; 2. Existing The construction enclosures are not windproof, and accidents of construction enclosures collapsing and hurting people often occur in typhoons
3. The existing construction works are not permeable to light, affecting the lighting and sightlines of nearby residents

Embodiment Construction
[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0028] Such as figure 1 As shown, the present invention provides a construction enclosure of the best first embodiment, comprising a first perforated panel 1 and a second perforated panel 2, and a resonant cavity is formed between the first perforated panel 1 and the second perforated panel 2 5. There is an air layer in the resonant cavity 5, and a silencer 3 is installed in the resonant cavity 5, and first through holes 10 are evenly arranged on the first perforated panel 1 (such as figure 2 shown), the second through-holes 20 are evenly arranged on the second perforated panel 2 (such as image 3 As shown), the two ends of the muffler tube 3 are respectively connected with the first through h...

The invention discloses a constructional engineering fence. The constructional engineering fence comprises a first perforated panel and a second perforated panel, wherein a resonant cavity is formed between the first perforated panel and the second perforated panel, an air layer is arranged in the resonant cavity, a silencing cylinder is installed in the resonant cavity, first through holes are evenly formed in the first perforated panel, second through holes are evenly formed in the second perforated panel, the two ends of the silencing cylinder are connected with the first through holes andthe second through holes, an airflow channel is formed in the middle of the silencing cylinder and communicates with the first through holes and the second through holes, silencing holes are formed inthe outer wall of the periphery of the silencing cylinder, the silencing holes communicate with the airflow channel, and the silencing holes are smaller than the airflow channel in diameter. According to the constructional engineering fence, sound waves penetrate through the silencing holes to enter the resonant cavity for noise reduction.
Description
technical field [0001] The invention relates to the field of building engineering construction, in particular to a building engineering enclosure. Background technique [0002] Nowadays, when carrying out municipal road construction, engineering fences will be used, and the use of engineering fences will vary according to the construction site and conditions. Construction projects must be fully enclosed. The main roads in the urban area or those with large crowds should not be lower than 2.5 meters, and the rest should not be lower than 1.8 meters. Generally, semi-enclosed is more common in municipal projects. The so-called semi-enclosed refers to the establishment of fences on two or three sides, one or two sides Open to facilitate the entry and exit of construction equipment and materials. The specific setting is determined according to the bidding documents, drawings, site environment, and construction organization design under the condition of ensuring safety. [0003]...
