Abstract
The invention is a constructing method for supporting the ground pit by using the steel structure collar beam, which includes following steps: (1) constructs the stress mechanism for resisting the lateral force of the ground pit according to the design demands; (2) the steel structure collar beam is arranged on top or the side surface of the stress mechanism; (3) digs the ground pit. The invention has simple process, short period, high efficiency, the contamination to environment can be reduced.
Description
Technical field
The present invention relates to fore shaft fine strain of millet and method thereof in building and the building engineering field pattern foundation pit supporting structure,
Specifically a kind of steel work fore shaft beam and utilize it to carry out the method for pattern foundation pit supporting structure.
Background technology
At present, in building and building engineering field, foundation pit support construction adopts steel reinforced concrete fore shaft beam (Guan Liang) to construct often, and there are some problems in steel reinforced concrete fore shaft beam in this method (Guan Liang):
1. because fore shaft beam (Guan Liang) is a reinforced concrete structure, so the program of its construction or operation are soil excavation → formwork → reinforcement fabrication colligation → concreting → form removals.There is the problem that operation is many, cost is high, long in time limit in this method.
2. because traditional fore shaft beam adopts reinforced concrete structure, determined that its access times are disposable, can't reuse that therefore, its cost is higher, especially the section of fore shaft beam and arrangement of reinforcement are all very big, and cost is often high.
3. when traditional steel reinforced concrete fore shaft beam need be removed, engineering quantity was very big on the one hand, and difficulty is also very big, and the also corresponding raising of cost on the other hand, also needs the place to stack and processing after the dismounting, also do not meet the environmental protection policy of country.
Summary of the invention
One of purpose of the present invention is in order to solve the problem that the above-mentioned background technology exists, to propose a kind of steel work fore shaft beam, making it have easy for installation, the reusable effect of energy.
For achieving the above object, the present invention adopts following technical scheme: a kind of steel work fore shaft beam is characterized in that fore shaft beam adopts steel structure member to make.
Can link to each other by linkage between the above-mentioned steel structure member.
Two of purpose of the present invention is in order to solve the problem that the above-mentioned background technology exists, and proposes a kind ofly to utilize above-mentioned steel work fore shaft beam to carry out the method for pattern foundation pit supporting structure.Make that it has that operation is few, the duration is short, construction is simple, effect is high, cost is low, reduce the effect to the pollution of environment.
For achieving the above object, the present invention adopts following technical scheme:
A kind ofly utilize above-mentioned steel work fore shaft beam to carry out the method for pattern foundation pit supporting structure, comprise the steps:
(1) resists the primary structure member of foundation ditch lateral force by the designing requirement construction;
(2) in the upper end or the side of above-mentioned primary structure member the steel work fore shaft beam is installed;
(3) excavation pit.
The present invention has following advantage:
1. because the steel work fore shaft beam is a member capable of being combined, adopt compound mode to connect, easy construction, operation is few, the duration is short.
2. the steel work fore shaft beam can be reused, and cost is low, has more the market competitiveness.
3. adopt the steel work fore shaft beam, because its reusable characteristics are not polluted environment.

The specific embodiment
Embodiment 1: with reference to Fig. 1, Fig. 5, the base pit stand construction of present embodiment is as follows:
(1) excavation foundation trench;
(2) construct in foundation trench according to designing requirement and lead wall;
(3) construction campshed or diaphragm wall or steel work soldier pile 1;
(4) wait to lead the wall effect and finish after, remove and lead wall;
(5) in the upper end or the side of campshed or diaphragm wall or steel work soldier pile 1 steel work fore shaft beam 2 is installed, this fore shaft beam 2 usefulness fore shaft fine strain of millet member 2-1 and steel structure connecting member 2-2 are connected and form.
Embodiment 2: with reference to Fig. 2, Fig. 5, the base pit stand construction of present embodiment is identical with embodiment 1.
Embodiment 3: with reference to Fig. 3, Fig. 5, the base pit stand construction of present embodiment is identical with embodiment 1.
Embodiment 4: with reference to Fig. 4, Fig. 5, the base pit stand construction of present embodiment is identical with embodiment 1.
In Fig. 5, the absolute altitude position of fore shaft fine strain of millet can be located at nature ground more than 3, natural ground or natural below ground as the case may be.At the bottom of the piece number 4 expression foundation ditches.Primary structure member (campshed or diaphragm wall or steel work soldier pile 1) is used to resist the foundation ditch lateral force.
Claims (3)
1, a kind of steel work fore shaft beam is characterized in that fore shaft beam adopts steel structure member to make.
2,, it is characterized in that linking to each other by linkage between the described steel structure member according to the described steel work fore shaft beam of claim 1.
3, a kind of job practices of utilizing the described steel work fore shaft beam of claim 1 to carry out pattern foundation pit supporting structure comprises the steps:
