Each inner wall surface is kept off, horizontally-supported, the vertical support in grid type support is fixed on enclosing by connection with bolt rod piece
Inner wall surface, internal stiffeners are fixedly connected by connection double steel pipe fastener with the vertical support of grid type support.
The steel case enclosure device for foundation pit construction, enclosing, the slot that draws water, seal plate by steel plate welding production and
At.
A kind of construction method of steel case enclosure device for foundation pit construction, it includes the following steps：
Using long-armed digging machine station deep pit excavation on the ground, underground water is not excluded for and plays the role of bank protection in foundation pit；
Steel case enclosure device is placed in foundation pit by step 2 using crane, by terrestrial positioning and to be immersed in foundation pit
Water in；
According to foundation depth framework of steel reinforcement can be arranged between steel case enclosure device and foundation pit slight slope in step 3；To improve
The intensity of building enclosure, framework of steel reinforcement are installed in place using crane；
Step 4, using conduit respectively inside steel case enclosure device, outside pour underwater concrete, steel case enclosure device
Internal concreting is suitable for reading to the slot that draws water, gradually poured after first casting concrete initial set outside steel case and foundation pit slope surface it
Between concrete, form firm concrete or armored concrete steel case building enclosure；
Step 5 waits for that concrete reaches intensity, and the water in foundation pit is drained first with water pump, then gradually removes steel case and encloses
Internal stiffeners inside shield slice off the bolt rod piece that inner wall is welded with, and clear up and draw water slot and drain ponding, being formed, there is steel case to enclose
Protection structure anhydrous deep basal pit safely；
Step 6, in deep basal pit, carry out structures construction.
The present invention uses above-mentioned design, is easy to make, easy for installation, with strong points, easy to operate, and support materials tool can
Recycling, opposite conventional construction method can accelerate progress, reduce the deep pit digging in more water areas, the area of slope, save material
Material reduces construction cost.

Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
A kind of steel case enclosure device for foundation pit construction as shown in Figure 1, Figure 2, it includes being welded according to the shape and size of foundation pit 6
The steel enclosing 1 of system, grid type support, internal stiffeners, the slot that draws water, seal plate, connection bolt rod piece, the white steel pipe of connection
Fastener；It is welded with several connection bolt rod pieces 10 in 1 inner wall of enclosing to connect horizontally-supported 4 and vertical branch of grid type support
Support 5, internal stiffeners 9 are connect with vertical support 5 to be formed firm support system and is integrally formed with enclosing.The lower part of enclosing is set
Draw water slot 2, draws water for excluding.Seal plate 3 is equipped with around enclosing inner wall, to prevent Groundwater infiltration after installing.
As shown in figure 3, connection is welded on 1 inner wall of enclosing with bolt rod piece 10 according to a determining deviation, to connect grid type
Horizontally-supported 4 and vertical support 5, horizontally-supported 4 of support and vertical support 5 are solid using connection double steel pipe fastener 11 and nut
It is scheduled on 10 top of connection bolt rod piece, internal stiffeners 9 are connected with each other and utilize connection double steel pipe fastener and vertical support 5
Connection resists the side of underwater concrete to form the support system being connected with each other inside enclosing to ensure that enclosing is indeformable
Pressure.
As shown in Figure 4, Figure 5, draw water slot 2 and seal plate 3 is welded using steel plate, is welded in the inner wall of enclosing 1 respectively
On.3 border of seal plate is arranged and is anchored in underwater concrete, to prevent Groundwater infiltration.The slot 2 that draws water is used for the row of drawing water
It removes, ensures that foundation pit provides condition without drawing water for underground structure construction.
As shown in fig. 6, enclosing 1 is placed in the foundation pit 6 full of underground water using crane, it is mixed then to pour sub-bottom
Solidifying soil 8 and underwater side wall concrete seven.
As shown in fig. 7, forming effective foundation pit steel case enclosure device after concrete generates intensity, enclosing is extracted out using water pump
Underground water in 1 removes internal stiffeners 9 and bolt rod piece, ultimately forms the foundation pit with steel case enclosure device.
The advantages of this steel case enclosure device and its construction method, is, the area of more moisture is contained in soil layer, excavates
Deep basal pit generally requires the slope of large area, and so then the floor space of foundation pit operation is larger, and construction operation it is long in time limit, disappear
The human and material resources of consumption are also more, and use this steel case enclosure device, need not use slope structure, and base is excavated only with excavator
Hole can so save a large amount of human and material resources and shorten the construction period.
