Description
Technical field
The invention belongs to foundation pit enclosure structure technical fields, and in particular to a kind of prefabricated foundation pit enclosure system and its construction
Method.
Background technique
Foundation pit enclosure structure is mainly made of soil-baffling structure and support construction.Wherein, soil-baffling structure receiving excavation of foundation pit unloads
Lateral water pressure and soil pressure caused by lotus, and this pressure is transmitted to support system, foundation pit enclosure structure is to stablize foundation pit
A kind of interim soil-baffling structure system of construction.The common form of soil-baffling structure has cement soil wall, steel sheet pile, campshed barricade, underground
Diaphragm wall etc., support construction is based on bracing members, concrete support etc..Cement soil wall, steel sheet pile are primarily adapted for use in excavation of foundation pit
Shallow foundation hole within depth about 6m, restricted application.Therefore, for deep-foundation pit engineering, mainly connected with campshed barricade and underground
Based on continuous wall.
Campshed building enclosure and underground continuous wall-enclosure structure construction technology are both needed to first in ground grooving, then will on the ground
The steel reinforcement cage processed is put in groove inlet section, is carried out underwater concrete using conduit and is poured, complete unit wall section (or
Stake), subsequent wall section (or stake) of then successively constructing.Campshed building enclosure can increase waterproof between piles measure, diaphram wall knot
Structure between each wall section due to utilizing specific connector to be connected with each other, and i.e. cocoa forms continuous reinforced concrete wall together for itself
Therefore wall can both realize earth-retaining, water retaining function.But, continuous underground wall structure has better globality, has
It preferably intercepts water, antiseepage, load-bearing, the functions such as water blocking.
After the completion of soil-baffling structure, starts to excavate downwards from ground, digs to designed elevation, need to first perform inner supporting structure,
After completing inner supporting structure, it can continue to excavate downwards, if any multiple tracks inner supporting structure, then after being excavated to respective support absolute altitude,
Be both needed to first set up support construction, after excavated, until be excavated to substrate absolute altitude.It has the following problems:
1, the binding construction process of soil-baffling structure and concrete inner supporting structure steel reinforcement cage is cumbersome, take a long time, manually at
This height and construction quality is unstable；
2, need to be after cast-in-place concrete support and reaches design strength after concrete inner supporting structure is set up, then carry out next
The excavation of layer soil body, the process take a long time；
Although 3, bracing members reach design strength after can setting up, bracing members are not so good as concrete support, Hen Duoshi
It waits bracing members and is unsatisfactory for requirement of strength design；
4, main structure returns and builds the stage, and pair of interior support structure is needed successively to remove from bottom to up, and the process is time-consuming and laborious, and props up
After support is removed, it may appear that soil-baffling structure and the biggish controlled load case of support construction stress.
Summary of the invention
In order to overcome the above technical defects, the first object of the present invention is there is provided a kind of prefabricated foundation pit enclosure system,
