Detailed Description

The following further description is made with reference to the accompanying drawings and specific embodiments.

Examples

The utility model provides a novel foundation ditch protection encloses fender, please refer to fig. 1 and fig. 2, hold in the palm 3, chain 4, sclerosis ground 5, expansion bolts 6 and baffle 7 including stand 1, nut 2, L type, and sclerosis ground 5 sets up in the peripheral subaerial of foundation ditch, and the lower extreme of stand 1 is provided with the rectangle board, and the rectangle board of stand 1 is through a plurality of

expansion bolts

6 and 2 fixed mounting of nut on sclerosis ground 5. L type holds in palm 3 and stand 1 welding and links to each other, and in order to can stable erection baffle 7, should weld at least on the stand 1 and hold in the palm 3 by two L types, in this embodiment, the welding has two L types to hold in the palm 3 on the stand 1, and each L type holds in the palm 3 and sets gradually along the direction of height of stand 1. The transverse part of the L-shaped support 3 is provided with a stud 301, the chains 4 are welded to the side walls of the baffle 7, in order to stably mount the baffle 7, two chains 4 are welded to two side walls at two ends of the length direction of the baffle 7 at least, in the embodiment, two chains 4 are welded to two side walls at two ends of the length direction of the baffle 7, and the chains 4 are arranged along the height direction of the baffle 7 in sequence. The hole of the chain 4 is sleeved on the stud 301 of the L-shaped support 3 and is fixed by the nut 2. When the baffle 7 is arranged between the two upright posts 1, the optimal length knot hole of the chain 4 is sleeved on the stud 301 of the L-shaped support 3, so that the baffle 7 can be firmly fixed.

The utility model discloses a theory of operation: the utility model discloses an upright 1 installs on sclerosis ground 5, and sclerosis ground 5 is waterproof and firm, receives rainwater erosion also can the stability, has ensured the firm installation of upright 1. The utility model discloses a stand 1 passes through expansion bolts 6 and nut 2 fixed mounting on sclerosis ground 5, can prevent effectively that stand 1 from being demolishd at will. The baffle 7 is arranged on the stud 301 of the L-shaped bracket 3 through the chain 4 and the nut 2, so that the baffle 7 can be effectively prevented from being randomly detached.

Because the length of the chain 4 can be adjusted, the positioning requirement on the upright post 1 is reduced, and when the baffle 7 is temporarily detached due to working requirements to cause slight inclination or slight bending damage to the upright post 1, the enclosure can still be installed in a restorable manner through the adjusting action of the chain 4. The baffle 7 can be fixed by adjusting the length of the chain 4 on the ground with little fluctuation, and the requirement on the ground flatness is reduced.

The setting of sclerosis ground 5 can be as shown in fig. 1, sets up to a whole, also can be as shown in fig. 3, separately sets up, sets up with stand 1 one-to-one, can further reduce when sclerosis ground 5 separately sets up the utility model discloses to the requirement of ground flatness.

To sum up, the utility model discloses the product is drawn materials easily, simple structure, practicality are strong, can effectively prevent moreover to be demolishd at will. In addition, the problems of difficult installation caused by uneven ground topography at the periphery of the foundation pit of a construction site and difficult installation recovery after dismantling can be well solved.

Referring to fig. 1, the position of the welding chain 4 on the sidewall of the baffle 7 corresponds to the position of the welding L-shaped bracket 3 on the upright post 1, so that the baffle 7 can be more conveniently installed.

Referring to fig. 4, the nut 2 is a cylindrical structure, and at least three insertion holes 201 are formed in the upper end surface of the nut 2, and the insertion holes 201 are uniformly formed along the circumferential direction of the nut 2. Nut 2 of structure like this needs to use like the specialized tool that fig. 5 shows just can demolish, uses tools such as spanner commonly used to can not demolish, so sets up and can further prevent the utility model discloses by demolising at will.
