Abstract
The utility model relates to a kind of Novel underground diaphragm wall, the Novel underground diaphragm wall wall is divided into supporting section and fixed section, and fixed section wall two sides are equipped at intervals with convex body, and the supporting section wall faces native face equipped with convex body.The utility model is suitable for " unification of two walls " formula diaphram wall, can effectively reduce the depth of traditional " unification of two walls " diaphram wall, while wall sedimentation can be effectively controlled.
Description
Technical field
The utility model relates to underground engineering technical field more particularly to a kind of Novel underground diaphragm walls.
Background technique
Diaphram wall is a kind of common underground engineering field construction technology, is usually used in the ultra-deep underground space and goes along with sb. to guard him to apply
Work, is also used for that environment is complicated or the underground space construction of key preservation area, mainly intercept water, antiseepage, earth-retaining the effects of.It has
Have it is highly-safe, control deformability it is good the advantages that, but also involve great expense simultaneously, site requirements it is high.
The diaphram wall of " unification of two walls " form not only has the function of intercepting water, antiseepage, earth-retaining, while there are also load-bearing
It is required that traditional " unification of two walls " form diaphram wall solves load-bearing and sedimentation in hard supporting course using ultra-deep wall is bottomed
The problem of, but the raising of project cost is also brought,
Utility model content
The utility model aim is to provide a kind of Novel underground diaphragm wall.The utility model is exactly to solve above-mentioned ask
Topic, a kind of Novel underground diaphragm wall are mainly used for " unification of two walls " form diaphram wall, by using wall width increase convex body, have
Effect reduces and acts on soil pressure on wall, while increasing side resistance, and the broadening of wall bottom increases end resistance, solves ground wall and holds
While weight and settlement issues, ground wall depth is effectively reduced, is improved efficiency, save the cost.
The utility model is realized by following technical approach:
A kind of Novel underground diaphragm wall is divided into supporting section and fixed section, and fixed section wall two sides are equipped with convex body, described
Supporting section wall faces native face equipped with convex body；
The fixed section is not dig out a section wall under underground structure bottom plate, and the supporting section is underground structure bottom plate up to wall
Push up section wall；
The broadening of fixed section wall bottom；
The convex body can be rectangle, hemispherical or the shape of falling bracket；
Dislocation arrangement can be used between adjacent wall width by the 5~8m of convex body interval.
Compared with prior art, the utility model has the advantage that
1, wall outer lug, which can effectively reduce, acts on soil pressure on wall, improves wall safety, increases simultaneously
Collateral resistance；
2, wall bottom wall width broadening effectively increases end resistance, while increasing build-in stability, can effectively reduce wall width
Depth improves efficiency, save the cost

Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
Embodiment
As shown in Figure 1, a kind of Novel underground diaphragm wall, the Novel underground diaphragm wall wall is divided into supporting section 1 and build-in
Section 2, the 2 wall two sides of fixed section are equipped with convex body 3, and 1 wall of supporting section faces native face equipped with convex body 3,2 wall of fixed section
Body bottom broadening 4.
A kind of Novel underground diaphragm wall and its construction method, content are as follows:
I, grooving mechnisiam construction grooving,
II, special power head 8 are wall bottom position is widened, wall side wall expands slot, to become formation convex body 3 and wall bottom after wall
Portion's broadening 4,
Wall steel bar cage 9 is transferred after III, borehole cleaning,
IV, casting concrete form wall,
V, underground structure bottom plate 6 is poured with supporting section 1 by integral, supporting section 1 by bottom plate position built-in fitting after excavation
Underground structure wall is collectively formed with inwall 5.
