Abstract
The utility model discloses a kind of foundation ditch vertical prestressing anchor pole supporting construction, Guan Liang is fixed at foundation pit enclosure stake top end, Guan Liang is fixedly connected horizontal-extending semi-girder on the outside of foundation ditch, semi-girder and the rock bolt being anchored at vertically in soil layer.The utility model is used after vertical prestressing anchor bar body system, the problems such as can not being used because of anchor pole valid bonding length deficiency caused by neighbouring foundation ditch has underground structure, invade subterranean zone outside red line and violate the regulations such as urban underground space planning is solved, the scope of application of anchor pole is expanded；Fender post horizontal displacement is reduced, bending can be reduced for bored concrete pile, the fender post ratio of reinforcement is reduced.
Description
Technical field
The utility model belongs to foundation ditch support technology field, relates in particular to a kind of foundation ditch vertical prestressing anchor pole support
Structure.
Background technology
With the progress of urbanization, construction land day is becoming tight.Building is as far as possible big in order to be obtained on limited soil
Usable floor area, on the one hand using height space turn into skyscraper, on the other hand to the underground development utilization underground space.This two
The trend of kind all make it that the basement of building does deeper and deeper, and the foundation depth that building is excavated is increased therewith.In order to ensure construction
The stabilization and surrounding building of stage foundation ditch, the safety of town road and facility, deeper building foundation pit, which can all be used, goes along with sb. to guard him knot
Structure and support system.Foundation ditch is deeper, and area is bigger, and the bigger cost of scale of building enclosure and support system is higher.To being at present
Only, support system has horizontal support, batter brace, anchor pole etc..To the little foundation ditch of depth, the bigger horizontal support of excavation area is made
Valency is higher；Horizontal support can be excavated with batter brace system to pit earthwork and underground main structure construction causes very big barrier
Hinder；Although the pull-type support system of anchor can solve the problem of earth excavation and inconvenient underground main structure construction, later stage main body is given
Structure construction provides facility, but anchor pole would generally invade the subterranean zone outside red line, and the use and underground to adjacent territories are empty
Between exploitation cause obstacle.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art to be supported there is provided a kind of foundation ditch vertical prestressing anchor pole
Structure.
The utility model is achieved through the following technical solutions：
A kind of foundation ditch vertical prestressing anchor pole supporting construction, Guan Liang is fixed at foundation pit enclosure stake top end, and Guan Liang is fixedly connected
The semi-girder of (i.e. horizontal-extending to soil mass of foundation pit side) horizontal-extending on the outside of to foundation ditch, semi-girder and the anchor being anchored at vertically in soil layer
Rod lock.
In the above-mentioned technical solutions, the vertical of embedded soil layer is equally spacedly poured in the foundation ditch soil layer side of foundation pit enclosure stake
To pile body, longitudinal pile body is together with foundation pit enclosure stake one-piece casting.
In the above-mentioned technical solutions, Guan Liang and semi-girder are fixed on the top of pile body longitudinally in each.
Advantage of the present utility model and have the beneficial effect that：
The utility model is used after vertical prestressing anchor bar body system, solves the anchor caused by neighbouring foundation ditch has underground structure
Bar valid bonding length is not enough and can not use, invade the outer subterranean zone of red line and violate regulations such as urban underground space planning etc.
Problem, expands the scope of application of anchor pole；Fender post horizontal displacement is reduced, bending can be reduced for bored concrete pile, is dropped
The low fender post ratio of reinforcement.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model in embodiment one.
Fig. 2 is structural representation of the present utility model in embodiment two.
Fig. 3 is the A of foundation pit enclosure stake in the cross-sectional view of foundation pit enclosure stake of the present utility model in embodiment two, i.e. Fig. 2
To section view.
Fig. 4 is top view of the present utility model in embodiment two.
Wherein：1 is foundation pit enclosure stake, and 2 be Guan Liang, and 3 be semi-girder, and 4 be anchor pole, and 5 be armored concrete basement bottom board, 6
For armored concrete outer wall of basement, 1-1 is longitudinal pile body.
Embodiment
The technical solution of the utility model is further illustrated with reference to specific embodiment.
Embodiment one：
Referring to accompanying drawing 1, a kind of foundation ditch vertical prestressing anchor pole supporting construction,
First, construction foundation pit fender post 1, foundation pit enclosure stake 1 can be pre- using deposited reinforced concrete pile, armored concrete
Stake processed, Section-steel Piles, steel sheet pile, the stake of SMW engineering methods；
Secondly, in foundation pit enclosure stake 1 top construction Guan Liang 2 and semi-girder 3, semi-girder 3 is to horizontal-extending (i.e. to base on the outside of foundation ditch
Cheat soil body side horizontal-extending), Guan Liang 2 and semi-girder 3 can be armored concrete, Steel material, when Guan Liang and semi-girder are reinforcing bar
During concrete material, Guan Liang answers one-piece casting with semi-girder；
Secondly, construction prestressed anchor 4, anchor rod body can be steel strand wires and reinforcing bar；
Finally, apply prestressing force to anchor pole, anchor pole top is locked with semi-girder 3.
Complete after above foundation ditch vertical prestressing anchor pole supporting construction, can subsequently carry out basement armored concrete underground
The construction of room base plate 6 and armored concrete outer wall of basement 6.
Embodiment two：
It is described on the basis of embodiment one in order to further strengthen the stability of foundation pit enclosure stake 1 referring to accompanying drawing 2-4
1 cross section of foundation pit enclosure stake is T-type structure (Fig. 3), i.e., equally spacedly poured in the foundation ditch soil layer side of foundation pit enclosure stake 1 embedding
Longitudinal pile body 1-1 of underground layer, longitudinal pile body 1-1 are together with foundation pit enclosure 1 one-piece casting of stake；In pile body 1-1 longitudinally in each
Top fix Guan Liang 2 and semi-girder 3 (Fig. 4), prestressed anchor 4 of then constructing, and anchor pole top is locked with semi-girder 3.
Exemplary description is done to the utility model above, it should explanation, do not departed from core of the present utility model
In the case of the heart, it is any it is simple deformation, modification or other skilled in the art can not spend creative work etc.
Protection domain of the present utility model is each fallen within replacing.
