Embodiment 1

[0040] Example 1: Combining Figure 1 to Figure 15Describe this embodiment, this embodiment includes a plurality of concrete retaining blocks 1 and a plurality of prestressed positioning connectors 2, a plurality of concrete retaining blocks 1 are arranged in sequence to form a retaining wall body, the retaining wall body The top is provided with a top layer 11, the bottom of the retaining wall body is provided with a base layer 3, and a plurality of prestressed positioning connectors 2 are evenly distributed in the retaining wall body;

[0041] Each prestressed positioning connector 2 comprises a nut 2-1, a cover plate 2-2, a prestressed steel bar 2-3, a steel bar connector 2-4 and an embedded steel bar 2-5 for applying prestressed force, and the cover plate 2- 2 Horizontally arranged between the side rib 13 and the middle rib 14 of one concrete retaining block 1 among the multiple concrete retaining blocks 1, the tops of the prestressed steel bars 2-3 pass through the concre...

Embodiment 2

[0045] Embodiment 2: In this embodiment, a plurality of concrete retaining blocks 1 are arranged in a staggered manner to form a retaining wall body. Staggered masonry is staggered masonry.

[0046] The concrete retaining block 1 in this embodiment is a new type of retaining block, and its size and shape can be varied according to user needs and site conditions. Two holes 12 are processed in the concrete retaining block 1. The hole 12 is a hole with a wide top and a narrow bottom. During laying, the difference between the top surface and the bottom surface is used to place the prestressed cover plate 2-2. The width of the side rib 13 of the hole 12 is half of the width of the middle rib 14. When the staggered joint is built, the hole 12 can be penetrated vertically, and the two adjacent concrete retaining blocks 1 in the vertical direction can realize the hole alignment. The effect of the hole is to facilitate the passage of prestressed steel bars 2-3.

[0047] In this embo...

Embodiment 3

[0049] Embodiment 3: The plurality of concrete retaining blocks 1 in the retaining wall body described in this embodiment that are in contact with the top layer 11 are the topmost block layer 4, and each concrete retaining block in the topmost block layer 4 The soil block 1 is connected to its adjacent concrete retaining block 1 through a plurality of pins 9, and the plurality of concrete retaining blocks 1 in contact with the topmost block layer 4 in the retaining wall body are the second Each concrete retaining block 1 in the top block layer 5 and the second top block layer 5 is connected to other concrete retaining blocks 1 on the same vertical line through a prestressed positioning connector 2 .

[0050] In this embodiment, the topmost block layer 4 uses multiple pins 9 to realize the connection with the second top block layer 5, which not only realizes the structural requirements, but also meets the force characteristics and needs of the actual retaining soil. Other struc...

Abstract

The invention provides an agglomerate-mode prestressed mortarless building block retaining wall and a construction method thereof in order to solve the problems of excavation of a reinforced retaining wall at an inclined slope and use height limitation of a rammed-earth retaining wall. A plurality of concrete retaining building blocks are sequentially arranged to form a retaining wall body; the top of the retaining wall body is provided with a pressure top layer, and the bottom of the retaining wall body is provided with a foundation layer; and a plurality of prestressed locating connecting pieces are uniformly distributed in the retaining wall body. The construction method provided by the invention comprises the steps of firstly, building the foundation layer; secondly, working before construction; thirdly, constructing the retaining wall body; fourthly, mounting the prestressed locating connecting pieces; fifthly, mounting other prestressed locating connecting pieces according to the operation process in the fourth step; sixthly, after finishing the mounting of the plurality of prestressed locating connecting pieces, ramming the topmost building block layer by using earth, and then, arranging the pressure top layer; and seventhly, constructing a soil layer at the rear of the retaining wall body.

Description

technical field [0001] The invention relates to a block retaining wall and a building method thereof, belonging to the technical field of building construction. Background technique [0002] As one of the oldest structural forms, there are several types of retaining walls: gravity type, cantilever type, buttress type, and assembled type. Concrete blocks, through splitting, old-fashioned and other technologies, can make stone-like effects, and their cost is less than half of stone. Using them to make retaining walls is not only beautiful, but also energy-saving, noise-reducing, and durable. Broad application prospects. The retaining wall has the function of retaining soil. Under the pressure of the soil, the simple block retaining wall is difficult to resist. The gravity retaining wall obtains the ability to resist sliding and overturning by its own gravity, and it is also the oldest form of retaining wall. Cantilevered retaining walls rely on steel reinforcement to withst...
