Description
Technical field
The present invention relates to foundation pit enclosure field, be specifically related to a kind of permanent foundation pit enclosure soil cement rigid wall and construction thereof
Method.
Background technology
Building or the foundation pit construction of structures, be usually and first carry out going along with sb. to guard him of foundation ditch, then excavate.Current foundation ditch encloses
Protect the mode combined with water-stop curtain frequently with colonnade formula stake, or (usual soil cement stirs to use the mode of cement mixing method
Mix the shaped steel that can insert some Disjunct distribution in stake)；But the foundation pit enclosure of these forms is interim measure, for construction building or structure
Build the transitional arrangement that the foundation ditch of thing is taked.
When excavation of foundation pit on earth after, in addition it is also necessary to carrying out the construction of building foundation pit sidewall in foundation ditch, building foundation pit sidewall is adopted
Taking formwork and lay reinforcing bar, then pouring reinforcement concrete forms permanent building foundation pit sidewall (i.e. sidewall of basement), connects
Needs and fill out husky to eliminate gap between building foundation pit sidewall and foundation pit enclosure, finally, the shaped steel in foundation pit enclosure is extracted
Recycle.Although the form of construction work that the foundation pit enclosure of current this interim measure is combined with permanent building foundation pit sidewall
Ensure that the intensity of building foundation pit sidewall, but its construction procedure is complicated, extends the construction cycle.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that one can be enclosed not affecting foundation ditch
Protect and on the premise of the intensity of permanent construction foundation pit side-wall, effectively reduce construction procedure, shorten the permanent of construction cycle
Property foundation pit enclosure soil cement rigid wall and construction method thereof.
The technical scheme is that
A kind of permanent foundation pit enclosure soil cement rigid wall, including cement soil continuous wall and the type that is plugged in cement soil continuous wall
Steel integral supporting structure, described shaped steel combination supporting construction includes that some length directions along cement soil continuous wall are arranged in order point
It is connected by eye-splice attachment structure between the vertical shaped steel of cloth, and adjacent two vertical shaped steel.
The foundation pit enclosure soil cement rigid wall of this programme acts not only as the foundation pit enclosure of construction building or structures,
During excavation pit, the pushing of collapsing in foundation ditch of the soil body stopped outside hole can be played, it is achieved the safe excavation of foundation ditch；And due to
The vertical shaped steel plugged in cement soil continuous wall, is connected by eye-splice attachment structure between adjacent two vertical shaped steel thus is formed
Continuous print shaped steel body of wall, thus terminate when excavation of foundation pit, it is also possible to take on the effect of permanent building foundation pit sidewall, can in order to avoid
Except the construction (i.e. sidewall of basement construction) of building foundation pit sidewall and fill out between building foundation pit sidewall and foundation pit enclosure husky with
Eliminate the construction procedure in gap.Thus this programme can not affect the intensity of foundation pit enclosure and permanent construction foundation pit side-wall
Under premise, effectively reduce construction procedure, shorten the construction cycle.
As preferably, eye-splice attachment structure is by the vertical slot being arranged on a vertical shaped steel and is arranged on another vertical type
The vertical plug-in unit matched on steel and with vertical slot.This programme connects adjacent two by vertical slot with vertical plug-in unit and erects
It is easy to practice of construction operation to shaped steel.
As preferably, vertical shaped steel is H profile steel, and the vertical slot of described eye-splice attachment structure is arranged on perpendicular with vertical plug-in unit
On the flange plate edge of shaped steel.
As preferably, between the web of adjacent two vertical shaped steel, form the receiving cavity of upper/lower terminal opening.This programme is tied
Full water earth will be filled in the receiving cavity of structure, so can improve the knot between vertical shaped steel and cement soil continuous wall further
Close intensity, and then improve stability and the intensity of permanent foundation pit enclosure soil cement rigid wall.
As preferably, vertical plug-in unit collectively forms T-shaped plug connector with the flange plate of vertical shaped steel.
As preferably, vertical plug-in unit is to be arranged on the flange plate edge of vertical shaped steel and perpendicular with flange plate vertical
Plate, and the width of vertical plate is more than the thickness of flange plate.
As preferably, vertical plug-in unit is the vertical inserted link being arranged on the flange plate edge of vertical shaped steel, and vertically inserted link
Internal diameter more than the thickness of flange plate.
As preferably, vertical slot is C-channel or T-slot or dovetail groove.
As preferably, the both ends open up and down of vertical slot.Due to the lower ending opening of vertical slot, so when vertical shaped steel
After inserting in cement soil continuous wall, soil cement will enter in vertical slot, and the pore filling in eye-splice attachment structure is full, work as water
Eye-splice attachment structure can be effectively improved after clay solidifying and connect the reliability and stability of adjacent two vertical shaped steel；And vertically insert
The upper end open of groove, so just can realize during second and follow-up vertical shaped steel insert in cement soil continuous wall
By eye-splice attachment structure, adjacent two vertical shaped steel are linked together, beneficially practice of construction operation.
The construction method of a kind of permanent foundation pit enclosure soil cement rigid wall, comprises the following steps successively:
First, along the cement soil continuous wall making one section of preseting length of wall direction construction in foundation soil；
Second, vertical shaped steel is inserted in cement soil continuous wall by length direction along cement soil continuous wall one by one, and when vertical
After shaped steel inserts in cement soil continuous wall, it is connected by eye-splice attachment structure between adjacent two vertical shaped steel, thus at cement
Continuous print shaped steel body of wall is formed in soil diaphragm wall；
3rd, return the first step and continue construction.
The invention has the beneficial effects as follows: can be before the intensity not affecting foundation pit enclosure and permanent construction foundation pit side-wall
Put, effectively reduce construction procedure, shorten the construction cycle.
