Description
Technical field
The present invention relates to the construction methods of a kind of Deep Thick Soft Ground Area cushion cap and basement bottom board.
Background technique
Cushion cap refers to bearing, being distributed the load transmitted by pier shaft, the steel for each stake top of connection being arranged at the top of pile foundation
Reinforced concrete platform.In the area that Deep Thick Soft Ground Area, especially mud are deep, in order to guarantee deep pit monitor, the soil of cushion cap
Side, which is excavated, to be generally required to carry out pattern foundation pit supporting structure, not only can guarantee speed of application using the method for steel sheet pile supporting, but also can guarantee in hole
The safety in hole.But according to conventional way, cushion cap and basement bottom board pour simultaneously, using steel sheet pile supporting,
As by the way of pouring simultaneously, steel sheet pile will be unable to extract, and cushion cap side waterproof construction is difficult, will definitely increase cost,
Speed of application is slow.
Summary of the invention
Technical problem to be solved by the invention is to provide the constructions of a kind of Deep Thick Soft Ground Area cushion cap and basement bottom board
Method, the defect that this method overcomes traditional cushion cap and basement bottom board to construct can be simple, efficient, safety complete using this method
It constructs at soft clay area cushion cap excavation supporting and basement bottom board, it is ensured that construction operation steel sheet pile safe and convenient recycles after extracting
It utilizes, save the cost.
In order to solve the above technical problems, the construction method of Deep Thick Soft Ground Area cushion cap of the present invention and basement bottom board includes such as
Lower step:
Step 1:, according to bearing platform construction drawing surveying setting-out, cushion cap edge positions are determined in the construction segment limit of division,
Certain distance construction steel sheet pile on the outside of cushion cap sideline；
Step 2: waist rail is arranged along steel sheet pile by calculating according to the depth of foundation pit, angle brace, length direction are set at waist rail angle
Waist rail between be arranged to support；
Step 3: cushion cap earth excavation to cushion cap cheats bottom absolute altitude, in cushion cap hole, bottom pour mold builds cushion cap bed course；
Step 4: removing angle brace, to support and waist rail, cushion cap position is released on cushion cap bed course, according to cushion cap position in cushion cap pad
Laying water-proof coiled material on layer, waterproof roll periphery has more cushion cap position certain length, and carries out protection, pours on waterproof roll
Waterproof protective layer；
Step 5: binding cushion cap reinforcing bar in waterproof protective layer, and in cushion cap position surrounding supporting module, installation template adds
Solid system pours cushion cap concrete to basement bottom board bottom absolute altitude；
Step 6: removing cushion cap surrounding template, the waterproof roll that cushion cap bottom has more certain length is translated into cushion cap side and fixation,
It lays waterproof roll in cushion cap side and rolls up the waterproof roll overlap joint come with cushion cap bottom and fix, pasted on the outside of waterproof roll anti-
Steel sheet pile is extracted after water conservation extruded sheet, cushion cap side backfill and compacting；
Step 7: this is constructed after all cushion caps press step 1 to step 6 construction in the construction segment limit of division
Section levelling of the land, raft contact face dabbing cleaning, pours basement bottom board bed course in cushion cap top surface, then in basement bottom board pad
It successively constructs on layer base plate waterproofing and waterproof slab protective layer；
Step 8: binding baseplate reinforcing bar on waterproof slab protective layer, baseplate reinforcing bar anchors into or penetrates through cushion cap reinforcing bar, pouring construction
Basement bottom board concrete in section completes basement bottom board construction.
Further, in step 1, apart from steel sheet pile 800mm on the outside of the cushion cap sideline.
Further, in step 4, the length that the waterproof roll periphery has more cushion cap position is 500mm.
It is since the construction method of Deep Thick Soft Ground Area cushion cap of the present invention and basement bottom board uses above-mentioned technical proposal, i.e., our
Method carries out cushion cap excavation by the way of steel sheet pile supporting, and waist rail, angle brace is arranged in steel sheet pile by calculating according to cushion cap depth
With to support, after the completion of excavation, bed course, construction waterproof and waterproof protective layer are poured, cushion cap reinforcing bar is bound in waterproof protective layer, so
Afterwards in cushion cap reinforcing bar surrounding supporting module, pour cushion cap concrete to basement bottom board bottom absolute altitude, construction bearing platform side waterproof and
Waterproof protective layer backfills the earthwork and extracts steel sheet pile after being compacted, after the construction section bearing platform construction of delimitation, pours basement
Bottom cushion, construct waterproof slab and waterproof protective layer, binds baseplate reinforcing bar, pours underplate concrete, completes basement bottom board
Construction.The defect that this method overcomes traditional cushion cap and basement bottom board to construct, can be simple, efficient, safety complete using this method
It constructs at soft clay area cushion cap excavation supporting and basement bottom board, it is ensured that construction operation steel sheet pile safe and convenient recycles after extracting
It utilizes, save the cost.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is this method Steel Sheet Pile, waist rail, angle brace and schematic diagram is arranged to support；
Fig. 2 is bearing platform construction schematic diagram in this method；
Fig. 3 is cushion cap side waterproof and waterproof protective layer construction schematic diagram in this method；
Fig. 4 is basement bottom board construction schematic diagram in this method.
Specific embodiment
Embodiment is as shown in Figures 1 to 4, and the construction method of Deep Thick Soft Ground Area cushion cap and basement bottom board of the present invention includes
