Referring to fig. 1 and 2, the utility model discloses a building retaining wall, including back up coat 100, wall body 200 and bank protection 300, wall body 200 sets up in the top of back up coat 100, and bank protection 300 sets up in the one side that wall body 200 met water.

Referring to fig. 1, a reinforcing layer 100 is provided in a plurality of layers and layered on a foundation, and a plurality of ground piles 130 inserted into the foundation are dispersedly inserted into the reinforcing layer 100. Specifically, the ground piles 130 are arranged in a quincunx manner in a scattered manner, the axial length of each ground pile 130 is six meters, the distance between every two adjacent ground piles 130 is 40 centimeters, at least more than half of the axial length of each ground pile 130 penetrates through the soft foundation and is inserted into the hard foundation of the river bed bottom or the lake bottom, and the diameter of the end part of each ground pile 130 inserted into the hard foundation is not less than 10 centimeters.

It should be understood that most of the time after the reinforcement layer 100 is repaired is completely submerged, the reinforcement layer 100 includes a gravel cushion layer 110 and a concrete cushion layer 120, the concrete cushion layer 120 is disposed above the gravel cushion layer 110, the top of the ground pile 130 is covered by the concrete cushion layer 120, and the gravel cushion layer 110 surrounds the periphery of the ground pile 130. During construction, a groove for placing the gravel cushion layer 110 is dug out, the ground pile 130 is inserted into the bottom of the groove, then gravel is poured into the groove to form the gravel cushion layer 110, and the gravel surrounds the periphery of the top of the ground pile 130; finally, a concrete pad 120 is covered on the upper surface of the gravel pad 110 to facilitate the installation of the wall 200 and protect the gravel pad 110 and the ground piles 130 at the bottom.

Referring to fig. 1, a wall body 200 is installed above a reinforcing layer 100, and has a water-facing surface and a water-backing surface; the wall body 200 is formed by pouring reinforced concrete, a backfill region 400 is arranged on the back surface of the wall body 200, and a concrete surface layer 410 is laid on the top of the backfill region 400 and is flush with the top of the wall body 200; the top of the wall 200 is provided with a guardrail 221. Specifically, the wall body 200 comprises a base 210 and a vertical wall 220, wherein the base 210 is installed above the reinforcing layer 100, the vertical wall 220 extends upwards along the vertical direction, and the base 210 is used for supporting the vertical wall 220; guard rail 221 is provided at the top of standing wall 220. The backfill region 400 is formed by filling structures such as stone ballast, and the upper part of the concrete surface layer 410 can be used for building roads, houses and the like. A guardrail 221 is provided on the top of the vertical wall 220 to protect pedestrians.

Furthermore, the thickness of the vertical wall 220 is gradually reduced from bottom to top, so that the weight of the vertical wall 220 can be effectively reduced; in addition, the standing wall 220 is inclined away from the upstream surface, i.e., in the direction of the backfill region 400. Since the backfill region 400 has a greater depth, the bottom of the vertical wall 220 is more stressed than the top, and therefore the vertical wall 220 needs to be configured to have a structure with a greater bottom thickness and a smaller top thickness; by arranging the standing wall 220 to be inclined toward the backfill region 400, the pressure applied to the standing wall 220 by the backfill region 400 can be partially transferred to the base 210, and thus the pressure resistance of the standing wall 220 is increased.

In some embodiments of the present invention, the connection between the base 210 and the standing wall 220 has a slope 230, and the area of the slope 230 on the back surface is larger than the area of the slope 230 on the front surface. As shown in fig. 1, the area mentioned herein refers to the surface area of the slope 230, and the back surface is the backfill region 400, so that the pressure of the contact surface can be effectively reduced by increasing the area of the slope 230 of the back surface, thereby achieving better protection of the wall 200. In addition, the slope 230 is higher near the end of the standing wall 220 than far from the end of the standing wall 220.

Referring to fig. 2, in some embodiments of the present invention, the vertical wall 220 has through holes 222 for communicating the upstream surface and the downstream surface, and the backfill region 400 has a filtering layer 420 corresponding to the through holes 222. Specifically, the through hole 222 is disposed at an upper position of the vertical wall 220, which should be higher than the water level, and the through hole 222 is disposed in an inclined manner, and the end of the water surface on the back side is higher than the end of the water surface on the upstream side, so that the water in the backfill region 400 can be conveniently discharged from the through hole 222. The reverse filtering layer 420 is also called a reverse filtering bag, and is made of 2-4 layers of sand, gravel or pebble and other materials with different particle sizes, the particles are gradually increased along the direction of water flow, and the particles of any layer are not allowed to pass through the pores of the adjacent thicker layer. The particles in the same layer cannot move relatively. After the inverted filter layer 420 is arranged, the soil in the backfill region 400 is not taken away when the seepage water flows out, so that the occurrence of piping and soil flowing can be prevented.

Referring to fig. 1, in some embodiments of the present invention, a revetment 300 is connected to the upstream surface of a wall 200 for sealing the joint between the wall 200 and a reinforcing layer 100. Specifically, the slope protection 300 is laid above the reinforcing layer 100 and extends in a direction away from the wall 200, and one end of the slope protection 300 is connected with the wall 200. The slope protection 300 covers not only the joint between the reinforcing layer 100 and the foundation but also shields the joint between the wall 200 and the reinforcing layer 100. Because the reinforcing layer 100 and the base 210 of the wall body 200 are in a submerged state most of the time, the arrangement of the revetment 300 can prevent water from directly entering from the joint between the reinforcing layer 100 and the foundation and the joint between the wall body 200 and the reinforcing layer 100 to cause erosion corrosion to the reinforcing layer 100 or the wall body 200, and prolong the service life of the wall body 200 and the reinforcing layer 100. In addition, be equipped with the bank protection 300 and extend towards the direction that deviates from wall body 200, can reduce submarine impurity or silt and surge to on the wall body 200.

According to the building retaining wall provided by the embodiment of the utility model, the soft foundation can be effectively prevented from sinking by arranging the multilayer reinforcing layer 100, so that the protection of the building is realized; the upstream surface of wall body 200 is provided with bank protection 300, and bank protection 300 covers on submarine surface, can seal the junction of back up coat 100 and ground and the junction of wall body 200 and back up coat 100 effectively to the life of extension barricade strengthens the building strength of barricade.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
