Embodiment 1

[0052] Example 1, such as figure 1 As shown, one aspect of the present invention provides a recyclable steel underground continuous wall unit, the continuous wall unit is followed by a receiving end 15, a transition section 16 and an insertion end 17 from left to right, and the receiving end 15 includes two The first wall panels 1 arranged at intervals in parallel and the water-swellable rubber water-stop strips 7 arranged on the inner side of the first wall panels 1 . The left end of the first wallboard 1 is preset with 12 holes for bolts, which are used for connection between the upper and lower units.

[0053] see further Figure 6As shown, the transition section 16 includes two second wall panels 2 arranged in parallel and at intervals, a vertical duct 5 arranged between the two second wall panels 2, a baffle plate 11, a steel box girder 3, and a water-resistant layer 6. The hydraulic jack 4 and the joint barrier layer 13, the baffle plate 11 is vertically arranged betwe...

Embodiment 2

[0072] Embodiment 2, the recyclable steel underground diaphragm wall unit is the same as Embodiment 1, except that the number of steel box girders 3 and vertical conduits 5 in the transition section 16 is adapted to the length of the second wall panel 2 . The vertical conduit 5 and the steel box girder 3 are arranged at intervals, and the number of spring bolts 10 is increased at the same time.

[0073] The unit structure of the recyclable steel underground diaphragm wall provided by the present invention is reasonably arranged, the transition section 16 can be arranged according to actual requirements, and the construction is flexible and convenient. The construction method overcomes the problems of poor waterproof performance at the joints of prefabricated reinforced concrete structures, sensitivity to the thickness of the enclosure structure sediment, uneven settlement and inclination that may easily cause potential safety hazards in the foundation pit, and the existing stee...

Abstract

The invention discloses a recyclable steel underground continuous wall unit and a construction method thereof. The continuous wall unit sequentially comprises a bearing end, a transition section and an insertion end from left to right, wherein the bearing end comprises two first wall plates which are arranged in parallel at intervals and water stop strips arranged on the inner side surfaces of thefirst wall plates; the transition section comprises two second wall plates which are arranged in parallel at intervals, a vertical guide pipe arranged between the two second wall plates, a baffle plate, a steel box girder, waterproof layers, a jack and a joint blocking layer, the baffle plate is vertically arranged between the two second wall plates, close to the left end part of the transition section, the joint blocking layer is arranged on the left side surface of the baffle plate; the waterproof layers are laid on the inner side surfaces of the second wall plates; and the jack is arrangedbetween the steel box girder and the second wall plate at the upper part, and the steel box girder and the second wall plate at the lower part are welded and fixed. The continuous wall unit has goodrigidity, strength and stability, improves the project quality, can be recycled, is green and environment-friendly, has short construction period, greatly reduces steel consumption, and reduces construction cost.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction, in particular to a recyclable steel underground continuous wall unit and a construction method thereof. Background technique [0002] With the continuous improvement of the level of urbanization, urban problems have become increasingly prominent, and the development and utilization of urban underground space has become one of the effective ways to solve the problems of big cities. At present, when excavating foundation pits in urban underground spaces, the enclosure structures are divided into cast-in-situ, prefabricated reinforced concrete structures and steel enclosure structures. [0003] The shortcomings of the current technology are: first, the construction period of the cast-in-place reinforced concrete structure is long; second, the construction quality cannot be guaranteed; third, materials are wasted during the construction process, and the processing costs during the...
