Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] As shown in Figure 1, the underground diaphragm wall milling method joint of the present invention includes two wall end faces opposite to the first-stage groove section of two adjacent underground diaphragm wall 1 sections, and a joint main body 2 is arranged between the two wall end faces The end surface of the wall and the end surface opposite to the joint main body 2 are provided with interengaging corrugated concave-convex bodies, and the joint main body 2 is fixedly connected to the underground continuous wall 1 at both ends through the intermeshing corrugated concave-convex bodies.

[0026] The construction technology of underground diaphragm wall milling method joint of the present invention comprises the following steps:

[0027] (a) Excavate the first-stage slots for pouring two adjacent walls, and the second-stage slots are between the two slots;

Abstract

The invention discloses an underground continuous wall milling connector and relative construction method. The inventive connector comprises two wall ends with opposite groove sections in nearby two sections of underground continuous walls, while a connector body is arranged between the two wall ends, the wall ends and the end of the connector body are arranged with corrugated concave-convex elements, while the corrugated concave-convex elements on the wall ends are meshed with the corrugated concave-convex elements on the end of connector body, the connector body via the meshed corrugated concave-convex elements is fixed with the underground continuous walls at two ends. And the construction method comprises that (a), digging the groove hole used to build two nearby walls, (b), arranging connector plate, (c), irrigating wall concrete, (d), forming guiding groove, (e), milling connector, (f), washing connector, (g), irrigating connector. The inventive connector has reasonable design, simple structure and construction, better anti-leakage property and low cost.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an underground continuous wall milling joint and a construction process thereof. Background technique [0002] At present, there are more than ten forms of construction joints of underground diaphragm walls at home and abroad according to the functions, uses and construction techniques of underground diaphragm walls. According to the different joint tools used, it can be divided into several common forms such as joint pipe (lock pipe), joint box, partition, I-beam, cross steel plate, improved joint and concave-convex prefabricated reinforced concrete wedge joint pile. The form of joint pipe joints uses less steel and is low in cost, but it requires a lot of one-time investment, which requires high lifting equipment and time control, and there are also problems with overall stiffness and leakage. Another example is the cross steel plate joint, whose construction technology u...
