    • Connectors for use in a retaining wall and a retaining wall having grooved blocks configured to receive the connector. Connectors can be used in various orientations within the grooves of the blocks. In a retaining wall, a flexible geosynthetic material fits into a channel of a channel connector, and is held in place by an elongate bar. The connector prevents abrasion of geosynthetic material. The connector can also be a plurality of spaced-apart projections for use with an apertured, relatively rigid geogrid. The connectors hold geogrid firmly in place, providing for increased connection capacity.
    • 用于挡土墙和挡土墙的连接器,其具有构造成接收连接器的开槽块。 连接器可以在块的凹槽内的各种取向中使用。 在挡土墙中,柔性土工合成材料装配到通道连接器的通道中,并通过细长的杆保持在适当位置。 连接器防止土工合成材料的磨损。 连接器也可以是多个间隔开的突起,用于与有孔的相对刚性的土工格栅一起使用。 连接器将土工格栅牢固地固定在适当位置,从而提高连接能力。

    • A retaining wall block has parallel top and bottom faces, a front face, a rear face, first and second side wall faces and a vertical plane of symmetry extending between the front and rear faces. The block is formed as a body portion including the front face, a head portion including the rear face and a neck portion connecting the body portion and the head portion. The body, head and neck portions each extend between the top and bottom faces and between the first and second side wall faces. An opening extends through the neck portion from the top face to the bottom face, dividing the neck portion to into first and second neck wall members extending rearwardly from the body portion to the head portion.
    • 挡土墙块具有平行的顶面和底面,前表面,后表面,第一和第二侧壁面以及在前表面和后表面之间延伸的垂直对称平面。 该块形成为包括前表面的主体部分,包括后表面的头部部分和连接主体部分和头部部分的颈部部分。 主体,头部和颈部各自在顶面和底面之间以及第一和第二侧壁面之间延伸。 开口从颈部延伸穿过颈部从顶面到底面,将颈部分隔成从主体部分向头部向后延伸的第一和第二颈壁部件。

    • A retaining wall block (1) has parallel top and bottom faces (2, 3), a front face (4), a rear face (5), first and second side wall faces (6, 7) and a vertical plane of symmetry (S) extending between the front and rear faces (4, 5). The block (1) is formed as a body portion (8) including the front face (4), a head portion (9) including the rear face (5) and a neck portion (10) connecting the body portion (8) and the head portion (9). The body, head and neck portions (8, 9, 10) each extend between the top and bottom faces (2, 3) and between the first and second side wall faces (6, 7). An opening (13)′ extends through the neck portion (10) from the top face (2) to the bottom face (3), dividing the neck portion (10) into first and second neck wall members (14, 15) extending rearwardly from the body portion (8) to the head portion (9). First and second pin holes (16 and 17) are each disposed in the body portion (8) and open onto the top face (2) for receiving a pin (50, 51) with a free end of the pin protruding beyond the top face. First and second pin receiving cavities (18, 19) are each disposed in the body portion (8) and open onto the bottom face (3) for receiving the free end of a pin (50, 51) received in a pin hole (16 and 17) of an adjacent block (1) disposed therebeneath so as to interlock the blocks (1) with a predetermined setback. The neck wall members (14, 15), pin holes (16 and 17) and pin receiving cavities (18, 19) are positioned such that a first plane (P1) extending parallel to the plane of symmetry (5) passes through the first pin receiving cavity (18), first pin hole (16) and first neck wall member (14) and a second plane (P2) extending parallel to the plane of symmetry (5) passes through the second pin receiving cavity (19), second pin hole (17) and second neck wall member (15).
