Embodiment Construction

[0011] The invention pre-buries the casing inside the underground continuous wall to facilitate construction and meet the requirements of the underground continuous wall for stress and basement waterproofing. In conjunction with the accompanying drawings, the specific description is as follows:

[0012] Such as figure 1 As shown, by pre-embedding the casing 2 in the underground diaphragm wall 1, when the post anchor rod 3 is constructed, it can directly pass through the underground diaphragm wall 1, avoiding drilling holes on the underground diaphragm wall 1, and finally fix the anchor rod 3 on anchor 4. Such as figure 2 As shown, before the casing 2 is fixed to the steel cage of the underground diaphragm wall 1, the water stop plate 6 can be welded to the casing 2. The thickness and width of the water stop plate 6 should be based on the geographical environment of the foundation pit project. Comprehensively determined. Before the casing 2 is fixed on the reinforcement ca...

Abstract

The invention belongs to the field of foundation pit support and relates to a casing for anchor rods passing through an underground diaphragm wall. The pre-embedded direction in the underground diaphragm wall is determined according to the insertion direction of the rear anchor rod, and the two ends of the casing are respectively sealed with rubber stoppers, and the two ends of the casing respectively pass through the longitudinal main reinforcement of the underground diaphragm wall outside, and inserted into the scope of the reinforced protective layer of the underground continuous wall. When the underground diaphragm wall is being constructed, the casing is arranged in the range of the wall body where the anchor rod must be provided in the diaphragm wall, so as to avoid chiseling the diaphragm wall during the construction of the anchor rod and meet the waterproof requirements of the basement.

Description

technical field [0001] The invention belongs to the field of foundation pit support for fixed buildings, and relates to a construction device for anchor rods passing through underground diaphragm walls, and can be widely used in foundation pit support projects using underground diaphragm walls combined with anchor rods. Background technique [0002] With the acceleration of urbanization in our country, the underground construction area is also increasing, the excavation depth is deepening, and the foundation pit support method is constantly innovating. For example, in soft soil areas, the excavation depth exceeds 12 meters. The relatively cheap "two walls in one" underground diaphragm wall is adopted; in areas with good soil quality, the foundation pit support scheme of bored piles combined with anchors is generally adopted, and anchors are used as the horizontal support system, which has great economic advantages. In the foundation pit engineering, if the support design sch...
