Description
Technical field
This utility model relates to civil construction field, is specifically related to a kind of vertical cross section-variable underground continuous wall and agent structure
In conjunction with building enclosure.
Background technology
Deep soft soil layer water content is high, infiltration coefficient is little, shearing strength is low, carries out base pit engineering under this geological conditions
Construction, difficulty is the highest, has the biggest risk.The pattern of going along with sb. to guard him that foundation pit construction is conventional mainly has diaphram wall, brill
Hole pouring pile, steel sheet pile, SMW engineering method, cement mixing method and composite soil nailing wall, wherein underground continuous wall-enclosure structure is due to wall
Body rigidity is big, and anti-permeability performance is good, applies widely in the deep-foundation pit engineering of deep soft soil layer, other building enclosure patterns
Mostly it is applied to the foundation ditch that cutting depth is shallower.At present, when soft soil layer is built subway open cut interval, it is also adopted by prismatic
Diaphram wall is as building enclosure, but separates (see figure 1) with agent structure, does not share the vertical load in agent structure.
Its advantage is: convenient construction, and construction quality is easily controllable；Vertical load is undertaken by agent structure completely, and stress is bright
Really, computational analysis is simple.
Its shortcoming is: diaphram wall is not subject to vertical load, wastes the vertical bearing capacity of diaphram wall.And
In soft soil layer, generally arranging pile foundation below agent structure, to control agent structure sedimentation, construction costs is high.
Utility model content
Separate with agent structure vertical applied force to solve conventional uiform section diaphram wall, do not undertake agent structure vertical
Load, causes diaphram wall vertical bearing capacity to waste, and agent structure is to reduce sedimentation to arrange the deficiency of foundation pile, this reality
The building enclosure that a kind of vertical cross section-variable underground continuous wall is combined is disclosed with agent structure with novel.
The technical solution of the utility model is: what a kind of vertical cross section-variable underground continuous wall was combined with agent structure goes along with sb. to guard him knot
Structure, it includes diaphram wall and agent structure, described diaphram wall centre position horizontally set concrete cushion, described
The bottom of agent structure contacts with concrete cushion, and the part that described diaphram wall is positioned at above concrete cushion is provided with first
Body of wall and the second body of wall, described first body of wall is positioned at above the second body of wall, and the first body of wall thickness less than the second body of wall
Thickness, above described agent structure, both sides are protruding and are fastened on the first body of wall and the junction of the second body of wall.
The height l of the first body of wall1Height l more than the second body of wall2。
First body of wall and the second body of wall integral structure.
The internal diameter of described first body of wall is more than the internal diameter of the second body of wall.
The height at the position that the height protruding above of agent structure does not highlights less than lower section.
The beneficial effects of the utility model: combined closely with agent structure by diaphram wall, make full use of underground continuous
Wall vertical bearing capacity so that it is diaphram wall principal parties structure vertical load, reduces the load on the basis of agent structure, excellent
Change basic engineering, save foundation pile, reduce engineering cost.
It has the advantage that
(1) diaphram wall vertical bearing capacity can be given full play to, make the vertical lotus of diaphram wall principal parties structure
Carry, reduce the load on the basis of agent structure, and then control agent structure sedimentation.
(2) can avoid in soft soil layer, arrange foundation pile to settle to control agent structure, reduce engineering cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of uiform section diaphram wall.
Fig. 2 is the structural representation of cross section-variable underground continuous wall.
Fig. 3 is the structural representation of agent structure.
Fig. 4 is the structural representation of diaphram wall.
Detailed description of the invention
Below for accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 2, Figure 3 and Figure 4, this utility model provides a kind of vertical cross section-variable underground continuous wall to tie with agent structure
The building enclosure closed, it includes diaphram wall 2 and agent structure 1, and described diaphram wall centre position horizontally set mixes
Solidifying soil padding, the bottom of described agent structure contacts with concrete cushion 4, and described diaphram wall is positioned at above concrete cushion
Part be provided with the first body of wall and the second body of wall, described first body of wall is positioned at above the second body of wall, and the first body of wall thickness
Less than the thickness of the second body of wall, above described agent structure, both sides are protruding and are fastened on the first body of wall and the second body of wall
Junction 3.
The height l of the first body of wall1Height l more than the second body of wall2, height more than concrete cushion is l0, concrete mats
Height below layer is l4, this highly can be configured according to the actual requirements, the first body of wall and the second body of wall integral structure.
The internal diameter of described first body of wall does not highlights less than lower section more than the internal diameter of the second body of wall, the height protruding above of agent structure
The height at position.Agent structure just can be stuck in the first body of wall and the junction of the second body of wall.
Cross section-variable underground continuous wall thickness is along vertical change, and from wall top down, the underground that AB section uses thickness to be d1 is even
Continuous wall, uses thickness to be the diaphram wall of d2 from BD section；D1 ＜ d2, thickness difference δ=d2-d1.Agent structure size is also in underground
Change at diaphragm wall variable cross-section B, the above agent structure of B point (agent structure top) width ratio B point following agent structure (body junction
Structure bottom) width increases by 2 δ.This structure, vertical load can be passed to underground even by B point cantact face by agent structure top
Continuous wall.Agent structure top vertical load includes dead load, upper overburden layer load etc., and these loads will be divided by diaphram wall
Load, significantly reduces the vertical load that agent structure bottom is born, and then reduces the load on the basis of agent structure, it is no longer necessary to
Agent structure sedimentation is controlled by arranging foundation pile.
Embodiment is not construed as the restriction to utility model, but any based on spirit improvements introduced of the present utility model,
All should be within protection domain of the present utility model.
