The anti-collision layer 4 adopts a multi-layer anti-collision net structure with staggered grid holes;

specifically, the anti-collision layer 4 comprises a plurality of reinforcing upright columns 8 which are arranged in a rectangular shape, a layer of anti-collision net is arranged on two adjacent reinforcing upright columns 8, the reinforcing upright column 8 on the outermost layer and the anti-collision net form a rectangular structure, more than two layers of protective layers can be arranged along the thickness direction according to the construction condition, and the protective layers are fixed by the reinforcing upright columns 8; the anti-collision net on one side of the reinforcing upright post 8 is provided with a reserved later grouting hole 7;

specifically, this application adopts four to be the reinforcement stand 8 that the rectangle set up, and two adjacent reinforcement stands 8 set up one deck anticollision net, four reinforcement stands between 8 formation rectangle structures.

The reinforcing upright post 8 adopts an angle steel structure; the anti-collision net is made of steel grids formed by opening holes in the steel plate. This application utilizes four reinforcing columns to form double-deck crashproof net structure, and double-deck steel net mutual staggered hole prevents that stone soil block from relying on inertial impact to pierce through the protective layer.

Grouting in the multilayer anti-collision net structure, and grouting P8-grade impermeable concrete by using a grouting pipe. The multilayer anti-collision net structure can effectively prevent the impact of backfill soil blocks and stones on the waterproof layer and the waterproof protective layer; the reinforcing upright post 8 is adopted as a support, meanwhile, the grounding body is embedded, and the later-stage impact knocking is avoided; the method can adapt to the actual situation that the backfill soil quality is not good in the current city. The whole prefabrication degree is high, and the construction is more efficient than the on-site bricklaying wall.

The construction method comprises the following steps of firstly constructing the basement concrete outer wall 1 during construction, constructing the basement outer wall waterproof layer 2 after the basement concrete outer wall 1 reaches design strength and the surface is repaired and leveled, wherein the waterproof layer 2 is the most critical protective layer for protecting the basement concrete outer wall 1 from water, pasting the buffer layer 3 after construction acceptance is finished, and the buffer layer 3 adopts a foam board and mainly bears the buffer effect of the anti-collision layer 4 after impact of backfill soil.

Increase buffer layer 4 outside buffer layer 3, buffer layer 3's shock resistance obviously obtains promoting, becomes to resist overall structure's impact by resisting single-point impact originally, and buffer layer 4 is that hollow structure has obvious cushioning effect to backfill soil impact moreover.

After the buffer layer 3 is constructed, the anti-collision layer 4 is laid, after earthwork backfilling, anti-seepage concrete is injected into the cavity in the anti-collision layer 4, the concrete is combined with the buffer layer 3 from the rear panel, the anti-seepage concrete effectively sticks to and is adhered to the buffer layer 3, and a rigid-flexible composite impermeable layer is achieved.

The structure of the anti-collision layer 4 is shown in figures 2-4, 5 is a rear panel hole, 6 is a front panel hole, 7 is a reserved post grouting hole, 8 is a reinforced upright post and is also a grounding body.

In the backfill construction, the soil stone blocks in the backfill are firstly blocked by the gap and the panel part without holes of the front panel hole 6, the gap diameter of the front panel hole 6 is the width between anti-collision net structures, and the rear panel gap and the front panel gap space are staggered, so that the stone blocks penetrating through the front panel gap can not break the rear panel again, and the effect of effectively blocking the soil stone blocks is achieved.

If the gap is not blocked by the soil stone, the backfill soil enters the space of the multilayer anti-collision net structure from the gap of the front panel hole 6, so that the filling amount of the anti-leakage concrete is reduced.

After the backfill construction is completed, the gap between the front panel and the rear panel is filled with the anti-leakage concrete through the reserved later grouting holes 7, the anti-leakage concrete fills the space, the front panel is bonded at the same time, and the backfill is permeated through the front panel.

The flat opening is beneficial to the tight fit of the two grids, and the joint surface and the linear expansion rubber strip can form a continuous and tight longitudinal seal surface.

The outer panel and the inner panel between the flat-mouth oppositely-clamped I-shaped adhesive tape 9 and the anti-collision layers 4 on the two sides are tightly attracted due to magnetism, so that the combination cannot be damaged due to backfill impact, and the combination can be tighter.

After the backfill construction is completed, if rain occurs, water permeating into the backfill meets the flat-mouth oppositely-clamping I-shaped adhesive tape 9, the flat-mouth oppositely-clamping I-shaped adhesive tape 9 absorbs water to expand and a gap between soil bodies is compressed, so that the outdoor water invasion can be effectively resisted, and the steel grid joint is prevented from leaking water.

The seepage of soil body in the gap at the front surface of the steel grid can reach the waterproof layer of the outer wall due to the effects of the impervious concrete in the grid, the rear panel and the like, and little water can reach the waterproof layer of the outer wall.

After the whole construction is finished, the later-stage grouting holes 7 are sealed and reserved, and the functions can be realized by connecting the angle steel grounding terminals.

The reinforced upright posts 8 are simultaneously used as grounding electrodes, and the grounding electrodes are metal conductors or conductor groups which are in direct contact with soil and are divided into artificial grounding electrodes and natural grounding electrodes. The grounding electrode is used as a conductor which is closely contacted with the earth and provides electrical connection with the earth, the energy of the safe dispersion lightning is leaked into the earth to realize the electrode connected with the earth, and in the electrical engineering, the grounding electrode is formed by nailing a plurality of galvanized angle steels with the length of 2.5M and the length of 45X45mm at the bottom of a groove with the depth of 800mm and then leading out by using a leading-out wire.
