Abstract
The invention provides a stage construction basement support change method using an underground continuous wall as separation containment. The method comprises the following steps that: 1, a separation containment structure using the underground continuous wall as a body is built, and in addition, pre-buried sectional steel is buried on the underground wall; 2, first-stage basement support change is carried out, support change sectional steel is welded at one end of the pre-buried sectional steel, and the other end of the support change sectional steel is cast with an underground slab of the first-stage basement; 3, secondary second-stage basement support change is carried out, support change sectional steel is welded at the other end of the pre-buried sectional steel in the same way, and a basement slab of the second-stage basement is cast at the other end of the support change sectional steel; 4, the underground continuous wall is dismounted, the pre-buried sectional steel is preserved, the connecting steel bars are tied and bundled, and concrete is cast, so the first-stage basement and the second-stage basement are connected. The support change problem of the front-stage construction basement and the back-stage construction basement can be perfectly solved, the support change effect is good, in addition, the basement structure can be smoothly built, and the construction is convenient.
Description
Technical field
The present invention relates to the realm of building construction, be specifically related to a kind of stage construction basement support change method of going along with sb. to guard him with the separation of diaphragm wall do.
Background technology
In the basement construction of construction projects, due to reasons such as place, safety or funds, usually need to carry out stage construction, stage construction is often taking diaphragm wall as separating space enclosing structure, after having constructed, diaphragm wall is removed, front and back two phases basement is connected.In aggregates for ensureing that basement can connect mutually, just must handle the support replacement problem of front construction in later period part well.Conventionally adopt at present the contrary mode of doing, along with the carrying out of construction successively removed diaphragm wall from top to bottom, so that front and back phase basement is communicated with, construction is trouble comparatively.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and makes to separate the stage construction basement support change method of going along with sb. to guard him with diaphragm wall, the support replacement problem of phase construction basement before and after can solving well, support replacement is effective, and can be along making basement structure, easy construction.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of stage construction basement support change method of going along with sb. to guard him with the separation of diaphragm wall do, comprises the following steps:
Step 1: build separation space enclosing structure taking diaphragm wall as main body between first phase basement and the second stage of basement, and the girder and the secondary beam position that are positioned at floor structure on diaphragm wall are embedded into pre-buried shaped steel;
Step 2: when the construction of first phase basement support change, at the support replacement shaped steel of one end of pre-buried shaped steel welding same model, the other end of support replacement shaped steel pours into the basement floor of first phase basement, and the side near diaphragm wall on the basement floor of first phase basement is reserved connecting reinforcement;
Step 3: when the second stage of basement support change construction, weld equally the support replacement shaped steel of same model at the other end of pre-buried shaped steel, the other end of support replacement shaped steel pours into the basement floor of the second stage of basement, and the side near diaphragm wall on the basement floor of the second stage of basement is reserved connecting reinforcement;
Step 4: carry out the dismounting of diaphragm wall from top to bottom, retain pre-buried shaped steel, connecting reinforcement between the basement floor of colligation first phase basement and the basement floor of the second stage of basement, concreting, couples together first phase basement and the second stage of basement.
As preferably, the thickness of described pre-buried shaped steel equals the wall thickness of diaphragm wall.
As preferably, described pre-buried shaped steel is hollow or H type.As preferably, when described basement floor is top board or base plate, building before basement floor, on basement floor near a side pre-embedded steel slab waterstop of diaphragm wall.Beneficial effect: the present invention adopts technique scheme to provide a kind of and makes to separate the stage construction basement support change method of going along with sb. to guard him with diaphragm wall, the support replacement problem of phase construction basement before and after having solved well, support replacement is effective, and can be along making basement structure, easy construction.

Detailed description of the invention
As shown in Figures 1 to 8, a kind of stage construction basement support change method of going along with sb. to guard him with the separation of diaphragm wall do, comprises the following steps:
Step 1: build the separation space enclosing structure taking diaphragm wall 1 as main body between first phase basement and the second stage of basement, and the girder 5 and secondary beam 6 positions that are positioned at floor structure on diaphragm wall 1 are embedded into pre-buried shaped steel 2, the thickness of described pre-buried shaped steel 2 equals the wall thickness of diaphragm wall 1;
Step 2: when the construction of first phase basement support change, at the support replacement shaped steel 3 of one end of pre-buried shaped steel 2 welding same model, the other end of support replacement shaped steel 3 pours into the basement floor 4 of first phase basement, and the side near diaphragm wall 1 on the basement floor 4 of first phase basement is reserved connecting reinforcement 7;
Step 3: when the second stage of basement support change construction, weld equally the support replacement shaped steel 3 of same model at the other end of pre-buried shaped steel 2, the other end of support replacement shaped steel 3 pours into the basement floor 4 of the second stage of basement, and the side near diaphragm wall 1 on the basement floor 4 of the second stage of basement is reserved connecting reinforcement 7;
Step 4: carry out the dismounting of diaphragm wall 1 from top to bottom, retain pre-buried shaped steel 2, connecting reinforcement 7 between the basement floor 4 of colligation first phase basement and the basement floor 4 of the second stage of basement, concreting, couples together first phase basement and the second stage of basement.
The support replacement problem of phase construction basement before and after having solved well, support replacement is effective, and can be with top-down along the basement of constructing as mode, easy construction.Pre-buried shaped steel 2 in step 1 is hollow or H type.3 length of support replacement shaped steel described in step 2 and step 3 are determined according to the force analysis of support replacement shaped steel 3.When described basement floor 4 is top board or base plate, building before basement floor 4, on basement floor 4 near a side pre-embedded steel slab waterstop of diaphragm wall 1.
