Detailed Description
In order to make those skilled in the art better understand the technical solution of the present application, the present invention will be further described in detail with reference to the accompanying drawings.
The terms of orientation such as up, down, left, right, front, and rear in the present specification are established based on the positional relationship shown in the drawings. The corresponding positional relationship may also vary depending on the drawings, and therefore, should not be construed as limiting the scope of protection.
The utility model discloses in, belong to "installation", "link to each other", "meet", "connect", "fixed" etc. and should do the generalized understanding, for example, can be fixed connection, also can dismantle the connection, also can connect integratively, also can be mechanical connection. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
The utility model provides a construction of underground continuous wall is prevented around flowing structure, its structure is shown as attached 1 and fig. 2, and it includes: the steel reinforcement cage comprises a steel reinforcement cage 1, I-shaped steel 2, a flow surrounding plate 3 and concrete 4.
The groove body on one side of the I-shaped steel 2 is close to the reinforcement cage 1, and the other side of the I-shaped steel is close to the soil body on two sides of the formed hole of the groove section; and two wing plates on one side of the I-shaped steel 2 facing the reinforcement cage 1 are respectively welded with a flow surrounding plate 3. The length of the flow surrounding plate 3 is the same as that of the I-steel 2, and the width of the flow surrounding plate extending out of the wing plate of the I-steel 2 is not less than a set width threshold value which is 1 m. The streaming plate 3 can be made of a thin galvanized plate, such as a galvanized sheet with a thickness of 0.2 mm. And pouring concrete 4 to form a groove section of the underground continuous wall together with the framework formed by the I-shaped steel 2 and the reinforcement cage 1.
The two flow-around plates 3 respectively welded on the two wing plates on one side of the I-shaped steel 2 facing the reinforcement cage 1 can be two or a whole flow-around plate 3.
When the flow-surrounding plates 3 are respectively welded on the two wing plates on one side of the I-shaped steel 2 facing the reinforcement cage 1, full welding is adopted between the flow-surrounding plates 3 and the wing plates of the I-shaped steel 2, so that the concrete at the joint part of the wall body can be prevented from flowing in the construction process of the underground continuous wall.
When the flow surrounding plate 3 is a whole piece, the middle part of the flow surrounding plate is leaned against the web plate of the I-shaped steel 2 facing to one side of the reinforcement cage 1, and the two end parts of the flow surrounding plate are bent and extend towards the outer sides of the upper wing plate and the lower wing plate of the I-shaped steel 2, under the condition, intermittent welding can be adopted between the two wing plates of the I-shaped steel 2 and the flow surrounding plate 3. Because the flow surrounding plate 3 is a whole plate attached to one side of the I-steel 2, the concrete flow surrounding at the joint part of the wall body can be still prevented in the construction process of the underground continuous wall even if intermittent welding is adopted between the two wing plates of the I-steel 2 and the flow surrounding plate 3.
The utility model discloses a welding is around flowing board 3 on the I-steel pterygoid lamina of 1 one side of underground continuous wall steel reinforcement cage, along with the close soil body that pastes of expanding behind the poured concrete, can prevent that the concrete from flowing around along the cage body of steel reinforcement cage 1 and the crack between the soil body to effectively improve underground continuous wall and connect anti seepage quality, reduced the brush wall work load that follow-up groove section connects antiseep water treatment simultaneously.
