Abstract
The invention discloses a kind of foundation pit structure, comprise gripper shoe, gripper shoe is provided with steel sheet pile near soffit place, two ends, steel sheet pile top card is connected in gripper shoe, be connected with between two steel sheet piles and agree with plate, agree with between plate with gripper shoe and be connected by steady pin, agree with plate soffit and fixing bloom is installed, fixing bloom is at least two, fixing bloom upper surface with agree with plate and adopt embedded connection, fixing bloom soffit is positioned on a bearing diagonal plate, bearing diagonal plate adopts del structure, fixing bloom is embedded in bearing diagonal plate, its both sides of bearing diagonal plate are vertically provided with support column, support column top is interted in bearing diagonal plate, a strengthened connection bar is positioned at bottom it, strengthened connection bar two ends are fixed on steel sheet pile.This foundation pit structure solves the problem that excavation difficulty is large and excavation supporting engineering quantity is large, and structural performance is good, and construction cost is low, and supporting capacity is strong, not easily occurs running pulp, good seepage-proof property, and ground balance is not easily damaged simultaneously.
Description
Technical field
The present invention relates to a kind of civil engineering structure, particularly a kind of foundation pit structure.
Background technology
When building main structures in high mountain gorge, need the foundation pit structure being formed building by the mode of excavation on the high gradient slope of both sides, valley, simultaneously when rich groundwater in construction area, building foundation is all sitting on Muddy Bottoms silty clay soil layer, and a lot of equipment Foundations depth of burying is larger, and part basis surrounding environment is complicated, adopt heavy excavation pick engineering completely impossible, just need in conjunction with comprehensive phenomenon when constructing like this, carry out assembling to foundation ditch to fill out and protect, generally need to use steel sheet pile, when constructing, steel sheet pile is imbedded in the soil body, to play certain supporting role, but steel sheet pile embedded depth is except the stability of guarantee itself, also should ensure to there will not be protuberance and Piping phenomenon in construction period bottom foundation ditch.Therefore, need especially to note, make it both cheat and play good support effect, there will not be again hole wall soil body flow, the problem sunk in top, hole.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, and provide a kind of and solve the problem that excavation difficulty is large and excavation supporting engineering quantity is large, structural performance is good, and construction cost is low, the foundation pit structure that supporting capacity is strong.
To achieve these goals, the technical solution used in the present invention is such: foundation pit structure of the present invention, comprise gripper shoe, gripper shoe is provided with steel sheet pile near soffit place, two ends, steel sheet pile top card is connected in gripper shoe, be connected with between two steel sheet piles and agree with plate, agree with between plate with gripper shoe and be connected by steady pin, agree with plate soffit and fixing bloom is installed, fixing bloom is at least two, fixing bloom upper surface with agree with plate and adopt embedded connection, fixing bloom soffit is positioned on a bearing diagonal plate, bearing diagonal plate adopts del structure, fixing bloom is embedded in bearing diagonal plate, its both sides of bearing diagonal plate are vertically provided with support column, support column top is interted in bearing diagonal plate, a strengthened connection bar is positioned at bottom it, strengthened connection bar two ends are fixed on steel sheet pile.
Further, as a kind of concrete form of structure, plate two ends of agreeing with of the present invention are separately installed with end plate.
Further, as a kind of concrete form of structure, bearing diagonal plate of the present invention adopts Steel material to make.
Further, as a kind of concrete form of structure, bearing diagonal plate of the present invention is welded on fixing bloom.
Further, as a kind of concrete form of structure, be filled with between support column of the present invention and steel sheet pile and cheat outer grouting layer.
Compared with prior art, the invention has the advantages that: this foundation pit structure solves the problem that excavation difficulty is large and excavation supporting engineering quantity is large, and structural performance is good, construction cost is low, and supporting capacity is strong, not easily occurs running pulp, good seepage-proof property, ground balance is not easily damaged simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
In figure: 1. gripper shoe; 2. agree with plate; 3. end plate; 4. fixing bloom; 5. steel sheet pile; 6. strengthened connection bar; 7. bearing diagonal plate; 8. support column.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The preferred embodiment of foundation pit structure of the present invention as shown in Figure 1, comprise gripper shoe 1, gripper shoe 1 is provided with steel sheet pile 5 near soffit place, two ends, steel sheet pile 5 top card is connected in gripper shoe 1, be connected with between two steel sheet piles 5 and agree with plate 2, agree with between plate 2 with gripper shoe 1 and be connected by steady pin, agree with plate 2 soffit and fixing bloom 4 is installed, fixing bloom 4 is at least two, fixing bloom 4 upper surface with agree with plate 2 and adopt embedded connection, fixing bloom 4 soffit is positioned on a bearing diagonal plate 7, bearing diagonal plate 7 adopts del structure, fixing bloom 4 is embedded in bearing diagonal plate 7, its both sides of bearing diagonal plate 7 are vertically provided with support column 8, support column 8 top is interted in bearing diagonal plate 7, a strengthened connection bar 6 is positioned at bottom it, strengthened connection bar 6 two ends are fixed on steel sheet pile 5, described plate 2 two ends of agreeing with are separately installed with end plate 3, described bearing diagonal plate 7 adopts Steel material to make, described bearing diagonal plate 7 is welded on fixing bloom 4, be filled with between described support column 8 and steel sheet pile 5 and cheat outer grouting layer.
Foundation pit structure of the present invention solves the problem that excavation difficulty is large and excavation supporting engineering quantity is large, and structural performance is good, and construction cost is low, and supporting capacity is strong, not easily occurs running pulp, good seepage-proof property, and ground balance is not easily damaged simultaneously.Described plate 2 two ends of agreeing with are separately installed with end plate 3, can better agree with, and are conveniently connected with external member; Described bearing diagonal plate 7 adopts Steel material to make, and enhances the structural of bearing diagonal plate 7; Described bearing diagonal plate 7 is welded on fixing bloom 4, is connected firmly, there will not be obscission; Be filled with between described support column 8 and steel sheet pile 5 and cheat outer grouting layer, slip casting can be carried out to it.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
