Description
Technical field
The utility model designs Base hole supporting technology field, relates in particular to a kind of detachable lightweight assembled foundation pit branch
Shield.
Background technique
Base pit engineering mainly includes excavation, precipitation and supporting, is a comprehensive system engineering.According to JGJ120-
99 " building foundation pit supporting technical regulations ", are divided into one, two, three to base hole sides safety grade, respectively correspond as to supporting knot
Structure destroys, sediment failure or excessive deformation are very serious on foundation pit surrounding environment and underground structure influence, general, not serious.As it can be seen that
Pattern foundation pit supporting structure is the core and emphasis of base pit engineering, and the quality of supporting construction will directly determine the quality of base pit engineering.
The purpose of pattern foundation pit supporting structure be protect Underground Construction go on smoothly and the safety of foundation pit surrounding environment, can
It is divided into temporary supporting and permanent supporting, what common engineering used is mostly temporary supporting, i.e., in the excavation of foundation pit stage to base
Take supporting means, after base pit engineering, remove supporting construction in hole.Traditional foundation pit supporting method include slope, campshed,
The modes such as soil nail wall, diaphram wall, cement soil wall, anchor pole, with the big rule of urban architecture speeded up the construction with the underground space
Mould exploitation, has also appeared some composite supporting constructions using some support technique.
Slope is to release enough side slopes according to certain gradient when excavation is more than certain depth, is suitable for shallow foundation and cheats
Engineering.This method has the advantages that safe and reliable, economical rationality, easy for construction, but for site requirements height, it is desirable that place is empty
Spacious and ground soil property is relatively good；Campshed supporting is using certain pile-type, the foundation pit supporting construction of queue-type arrangement composition, with regard to material
For, including the forms such as artificial digging pile, cast-in-situ bored pile, precast rc slab stake, but in contrast, higher cost,
Utilization rate is low and installing and dismounting is cumbersome；Diaphram wall is the deep trouth long and narrow in underground excavation section by section, and steel reinforcement cage is put into slot,
Casting concrete again forms reinforced concrete wall section, these wall sections are finally linked to be continuous underground wall together.Connect in underground
In the design process of continuous wall, on the one hand, designer keeps the ratio of reinforcement of diaphram wall higher, cause for secure context considers
Serious economic waste；On the other hand, owner requires the design economical rationality of deep foundation pit supporting structure, often in design process
In cause ignoring for some unfavorable factors, lead to the generation of foundation pit accident.It, in the construction process will be to underground in order to avoid accident
The reinforcement stresses of diaphragm wall, strain carry out tracking and monitoring, but this method will expend a large amount of fund.

Long straight bolt 17 is set at the top of standard component and connects vertical direction standard component, does not also need that short straight bolt 16 is all arranged on both sides
Horizontal direction standard component is connected, worry is directly contacted with foundation pit side-wall to boundary, and force-bearing situation is more complicated, therefore side is arranged
Curved bolt hand hole and screw hole improve the globality of lateral standard component and longitudinal standard component using the curved bolt in side.
As shown in fig. 6-7, longitudinal standard component A (5) is in an intermediate position in whole foundation pit supporting construction, needs to connect water
It is longitudinal to connect other standards block by the straight bolt 17 of length in design in the horizontal direction for the other standards part of gentle vertical direction
Standard component connects the lateral standard component of this standard block by curved bolt 18 in vertical direction.Therefore, it is necessary in prefabricated construction coagulation
Before soil pours, pre-buried cast iron hand hole and bolt hole pipeline are needed, forms curved bolt hand hole 11, screw hole 12, and long straight bolt spiral shell
Hole 13.As shown in figure 8, longitudinal direction standard component B (6) is in boundary position in whole foundation pit supporting construction, it is only necessary to which connection is up and down
The other standards part in direction connects other standards block longitudinal direction standard component by the straight bolt 17 of length in design in the horizontal direction, leads to
Cross the lateral standard component that curved bolt 18 connects this standard block in vertical direction.Therefore, it is necessary to before prefabricated construction concreting,
Pre-buried cast iron hand hole and bolt hole pipeline are needed, curved bolt hand hole 11, screw hole 12, and long straight bolt screw hole 13 are formed.
As shown in figure 9, utility model device provides 3 kinds of bolt designs, respectively short straight bolt 16, long straight bolt
17, curved bolt 18.Hexagonal is arranged for connecting lateral standard component, dimensions length 170mm in the horizontal direction in short straight bolt 16
Nut A (19) and hex nut A (21), is highly 20mm, diameter of bolt 20mm；Long straight bolt 17 for connecting in the horizontal direction
Longitudinal standard component is connect, connects lateral standard component in vertical direction, dimensions length 500mm is arranged hexagonal (hexagon)nut B (20) and six
Angle nut B (22) is highly 30mm, diameter of bolt 20mm；Curved bolt 18 is used to connect lateral standard component and longitudinal standard component,
Its Axis arc length is 203.63mm, and central angle is 80 °.
As shown in Figure 10, foundation pit supporting construction intermediate standard block 23 is made of lateral standard component A and longitudinal direction standard component A, this
It is bolted inside calibrated bolck by the way that eight fronts are curved, is connect in the horizontal direction by eight short straight bolt with other standards block,
It is connect by eight long straight bolt with other standards block in vertical direction；As shown in figure 11, foundation pit supporting construction boundary standard block A
(24) it is made of lateral standard component B, longitudinal direction standard component A and longitudinal direction standard component B, passes through eight curved bolts in front inside this standard block
With two sides are curved is bolted, connect by four short straight bolt with other standards block, led in vertical direction in the horizontal direction
Eight long straight bolt is crossed to connect with other standards block；As shown in figure 12, foundation pit supporting construction boundary standard block B (25) is by laterally marking
Quasi- part A, transverse direction standard component D and longitudinal direction standard component A composition, this standard block inside is bolted by the way that eight fronts are curved, in level
Direction is connect by four short straight bolt with other standards block, leads to four long straight bolt in vertical direction and other standards block connects
It connects；As shown in figure 13, foundation pit supporting construction angle calibrated bolck (26) by lateral standard component A, lateral standard component C, longitudinal direction standard component A and
Longitudinal standard component B composition, by the curved bolt in eight fronts and two sides are curved is bolted inside this standard block, in the horizontal direction
It is connect by four short straight bolt with other standards block, leads to four long straight bolt in vertical direction and connect with other standards block.
