The utility model relates to the technical field of building construction, and disclose a building construction is used pit guardrail, including net guardrail, the both sides of net guardrail are equipped with stand, the both sides of stand are equipped with the limit slot, the both sides of net guardrail are fixedly installed with the limit rod, the outer wall of limit rod is inserted in the inside of limit slot, the top of stand is screwed with the limit cap, the utility model discloses the limit slot of stand both sides and the limit rod cooperation of two net guardrail sides, can preliminarily limit two net guardrails in the both sides of stand, and through the setting of limit cap, can be screwed and installed in the top of stand, make the both lower pressure of limit cap bottom in the top of two net guardrails, be convenient for fast to the net guardrail of stand both sides and carry out the limit fixed, adopt this kind of mode to be convenient for to the net guardrail of stand both sides and carry out installation, thereby save the time of staff, improve installation efficiency.

This utility model provides a dust suppression mechanism for a crushing workshop, comprising U-shaped plates on the left and right sides. Each U-shaped plate has a mounting plate at its top, and multiple rotating shafts are rotatably mounted on the inner ends of each mounting plate. Water spray pipes are positioned between corresponding rotating shafts on the inner ends of the two mounting plates. Connecting flanges are mounted on the tops of the multiple water spray pipes, and multiple water spray heads are mounted on the bottoms of the multiple water spray pipes. This dust suppression mechanism for a crushing workshop not only meets the basic requirement of dust suppression during crushing and settling, but also allows the water spray heads to swing via a swing mechanism, preventing dust from overflowing between adjacent water spray pipes, reducing the cost of using the device, and meeting user needs.

The utility model provides a construction waste winnowing device, and belongs to the technical field of construction waste treatment. The building waste winnowing device comprises a feeding assembly and a winnowing assembly, the feeding assembly comprises a box body, a feeding barrel, a rotating plate and a spring, the feeding barrel is arranged at the top of the feeding barrel in a communicating mode, and the winnowing assembly comprises a sorting column, a blowing pipe, an air blower, a dust outlet pipe and a water tank. According to the construction waste winnowing device, construction waste can be evenly dispersed, so that the construction waste evenly falls, the falling caked construction waste can be impacted and separated, follow-up sufficient winnowing is facilitated, dust blown out in the winnowing process can be guided by arranging a sorting column, an air blowing pipe, an air blower, a dust outlet pipe and a water tank, and the dust can be effectively separated. And water passing through the water tank plays a good role in dust falling, so that the dust removal device is worthy of being popularized vigorously.

The utility model relates to the technical field of raised dust treatment, in particular to a raised dust treatment device for constructional engineering, which comprises a shell, a water inlet cylinder and a conveying mechanism, the water inlet cylinder is mounted on the shell, a dust falling mechanism is detachably connected onto the conveying mechanism, a support is mounted on the shell, and an extension mechanism comprises two fixing rings. Two fixing rings are fixedly connected to the first spraying pipe in a diagonal mode, second spraying pipes are connected to the two fixing rings in a sliding mode, two first connectors are connected to the first spraying pipe in a diagonal mode, second connectors are fixedly connected to the two second spraying pipes in a diagonal mode, and middle pipes are connected to the two second connectors in a sliding mode; the end of the middle pipe abuts against the first connector, and springs are clamped between the two second spraying pipes and the middle pipe. The length of the water spraying pipe can be increased, the dust suppression device is suitable for dust suppression of different areas, and the extending water spraying pipe can be rapidly stored when the dust suppression device is not used.
