[0004] Regarding the above-mentioned related technologies, since the length of the foundation pit is generally longer than the width of the foundation pit, during the laying process, the skynet is generally laid along the width direction of the foundation pit; that is, the length direction of the foundation pit is perpendicular to the length direction of the skynet, and when laying the skynet above the foundation pit, it is necessary to lay multiple skynets in parallel; for this reason, there is no connection between the skynets after laying, and there are gaps or gaps appear between adjacent skynets in windy weather, resulting in a defect of poor protection effect. Summary of the invention

[0005] In order to solve the defect of poor protection effect, the present application provides a skynet dust prevention system for foundation pit construction.

[0006] The present application provides a skynet dust prevention system for foundation pit construction, which adopts the following technical scheme: comprising: a skynet, which is laid along the length or width direction of the foundation pit; and two adjacent skynets are overlapped; a bearing rod, which is located below the overlap of the two adjacent skynets, and the length direction is the same as the length direction of the skynet; it is used to connect to the ground and support the skynet; a locking piece, which is located above the two adjacent skynets and slides along the length direction of the bearing rod, and is used to connect the skynet to the bearing rod.

[0007] By adopting the above technical scheme, the overlapping skynets in windless weather can reduce the dust generated during the foundation pit construction from flying out from the gaps between adjacent skynets, thereby reducing pollution to the outside world. At the same time, after the overlapping skynets are connected to the bearing rods using locking components, when the weather is windy, the overlapping skynets are also connected to the bearing rods, thereby reducing the falling dust generated during the construction process and improving the protection effect. At the same time, after the locking parts connect the skynet to the bearing rods when there is wind, the shaking of the skynet can be reduced, thereby improving the durability of the skynet.

[0008] Preferably, the locking member includes: a locking nail for clamping the overlapping part of the two adjacent nets to the bearing rod; the locking nail includes a bending rod and a clamping rod, two clamping rods are provided, and the clamping rods are vertically fixedly connected to the two ends of the length direction on the same side of the bending rod; the length of the bending rod is greater than the width of the bearing rod; a storage member is used to store multiple locking nails; the storage member is a tubular structure, and the bottom plate of the storage member is provided with a plug-in hole for the bearing rod to be placed along its length direction; the clamping rod abuts against the upper surface of the bottom plate of the storage member; the storage member is provided with a nail outlet hole at the end along its sliding length direction; the nail outlet hole passes through the storage member; a power member is connected to the front end of the storage member to drive the storage member and the locking nail to slide along the length direction of the bearing rod; a limiting member is connected to the rear end face of the storage member; a pressing member is connected to the storage member, inserted into the nail outlet hole, and used to fix the locking nail outside the bearing rod.

[0009] By adopting the above technical solution, when the overlapping skynet is connected to the bearing rod by using the locking part, the power part drives the storage part to slide along the length direction of the bearing rod, and the locking nail is pressed from the nail hole to the bearing rod. At this time, the bending rod is bent, and the clamping rod clamps the bearing rod, thereby achieving the fixation of the skynet and the bearing rod. At the same time, when the locking nail is used up, the limit part is removed to replenish the locking nail, thereby achieving the effect of facilitating the use of the staff.

[0011] By adopting the above technical solution, when the power part is used, the adjusting cylinder drives the clamping plate to slide to the side away from each other. When the lap plate is overlapped on the skynet and the load-bearing rod, the adjusting cylinder drives the clamping plate to move to the side close to each other. At this time, the walking wheel is pressed against the lower surface of the load-bearing rod, and the adjusting cylinder is started. The adjusting cylinder drives the lap plate to move forward. At this time, the power part will not be offset, and at the same time, the skynet is pressed against the load-bearing rod, which is convenient for the locking nail to lock the load-bearing rod and the skynet.

[0017] Preferably, a connecting rod is provided between adjacent locking nails, and the connecting rod is located at both ends of the length direction of two adjacent bending rods.

[0018] Preferably, a breaking groove is provided on the upper surface of the connecting rod.

[0019] By adopting the above technical solution, the provision of the breaking groove can facilitate the separation of adjacent locking nails.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. When the weather is calm, the overlapping sky nets can reduce the dust generated during the foundation pit construction process from flying out from the gaps between adjacent sky nets, reducing pollution to the outside world. At the same time, after the overlapping sky nets are connected to the bearing rods using the locking components, when the weather is windy, the overlapping sky nets are also connected to the bearing rods, thereby reducing the dust generated during the construction process. At the same time, when the locking parts connect the sky nets to the bearing rods when there is wind, the shaking of the sky nets can be reduced, thereby improving the durability of the sky nets;

[0022] 2. When the overlapping skynet and the bearing rod are connected by the locking piece, the power piece drives the storage piece to slide along the length direction of the bearing rod. At this time, the locking nail is pressed from the nail hole to the bearing rod. At this time, the bending rod is bent, and the clamping rod clamps the bearing rod, thereby achieving the fixation of the skynet and the bearing rod. At the same time, when the locking nails are used up, the limit piece is removed to supplement the locking nails, thereby achieving the effect of facilitating the use of the staff;

[0023] 3. When using the power part, the adjusting cylinder drives the clamping plate to slide to the side away from each other. When the lap plate is overlapped on the skynet and the load-bearing rod, the adjusting cylinder drives the clamping plate to move to the side close to each other. At this time, the walking wheel is pressed against the lower surface of the load-bearing rod, and the adjusting cylinder is started. The adjusting cylinder drives the lap plate to move forward. At this time, the power part will not be offset, and the skynet will be pressed against the load-bearing rod, which is convenient for the locking nails to lock the load-bearing rod and the skynet.
