[0012] Preferably, the cable is fixed by a binding rope.

[0013] Preferably, a cover plate is provided on the top of the cable trench.

[0014] Preferably, the bolt is an anchor bolt.

[0015] Beneficial effects of the utility model:

[0016] The utility model can install the lying rail in the cable trench to reduce the occupied area; the lying rail and the bottom of the cable trench are fixed with bolts, so that the cable can be directly laid after the lying rail is removed, that is, the cable trench and the foundation of the mobile dustproof shed are used in combination, which effectively solves the problem of large occupied area.
