[0006] Further, when the edge of the trench foundation is a soil subgrade, the bottom of the steel pipe is inserted into the subgrade for fixation.

[0007] When the edge of the trench foundation is a hardened pavement, a detachable steel plate is provided on the bottom of the steel pipe, and the detachable steel plate is fixed on the hardened pavement by expansion bolts.

[0008] Further, the steel wire rope connected between adjacent steel pipes is arranged with at least three parallel rows, each row is connected by a plurality of steel wire ropes connected end to end, adjacent steel wire ropes are connected by basket bolts, and the end of the steel wire rope is clamped and fixed on the basket bolt by a lock bolt.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] 1、The utility model is simple to make and install, and can be combined and installed according to various site conditions, improving the reliability and installation and disassembly efficiency of the temporary edge protection fence of municipal engineering trench foundation, and greatly improving the construction efficiency of edge protection.

[0011] 2、The utility model discloses can combine with a variety of warning things (warning belt, light belt, protective net), improve the safety of on-site construction.

[0012] 3、The utility model discloses simple operation of installation and dismantling, and does not need large -scale machinery and equipment to carry, since the overall device quality is lighter, the storage and placement space is small, and the utilization rate of the fence is improved, the construction cost is more saved, the material reutilization rate is high, and energy -conserving and environment -friendly. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the structure schematic diagram of a preferred embodiment of the utility model.

[0014] Figure 2 It is Figure 1 The enlarged schematic view of A in the middle. DETAILED DESCRIPTION

[0015] The utility model will be further explained in detail in combination with the drawings and specific embodiments.
