Preferably, strengthen in structure for the basement side bar controlling deformation of deep excavation above-mentioned, the depth-width ratio of described haunch bracket is 1:2.
Preferably, strengthen in structure at the above-mentioned basement side bar for controlling deformation of deep excavation, described in increase side bar and join large hoop and be connected with described former design side bar.
Preferably, strengthening in structure at the above-mentioned basement side bar for controlling deformation of deep excavation, increasing in side bar and structure girder described in the main muscle of described haunch bracket anchors into respectively.
Preferably, strengthen in structure for the basement side bar controlling deformation of deep excavation above-mentioned, described former design side bar and described increasing between side bar arrange reinforced mesh.
Preferably, strengthen in structure above-mentioned for the basement side bar controlling deformation of deep excavation, the foundation ditch layer second from the bottom that described structure girder is positioned at reverse construction.
The beneficial effects of the utility model are as follows: the utility model is by peripherally by foundation ditch setting up and increase side bar in the below of the former design side bar at wall place, and the structure girder vertical with former design side bar is carried out haunch process namely haunch bracket is set, 609 steel pipes for replacement floor tiltedly throw support, not only simplify difficulty of construction, and shorten the construction period greatly, better serve the effect controlling the wall lateral displacement distortion of deep foundation ditch ground.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments to being described in further detail for the basement side bar reinforcement structure controlling deformation of deep excavation of the utility model proposes.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
Refer to Fig. 1 and Fig. 2, present embodiment discloses a kind of basement side bar for controlling deformation of deep excavation and strengthen structure, comprise and increase side bar 1 and some haunch brackets 2, describedly increase the below that side bar 1 is arranged at former design side bar 3, described haunch bracket 2 is arranged at the below with described former design side bar 3 intersection area on structure girder 4.Described former design side bar 3 and increase side bar 1 is arranged at the ground wall 5 of foundation ditch inner side around a circle.Set up by the below of former design side bar 3 and increase side bar 1, the contact area between structure side bar entirety (comprise former design side bar 3 and increase structure side bar 1) and ground wall 5 can be improved, by setting up haunch bracket 2 with the below of described former design side bar 3 intersection area on structure girder 4, the more balanced structure girder 4 that is firmly delivered to of the lateral force that ground wall 5 can be subject to gets on, thus effectively can control the lateral deformation of ground wall 5.Support method tiltedly thrown by the base plate steel pipe that this structure can replace prior art to adopt, and compares base plate steel pipe and tiltedly throws support method, not only simplify difficulty of construction, and shorten the construction period greatly.
Preferably, strengthen in structure at the above-mentioned basement side bar for controlling deformation of deep excavation, described haunch bracket 2 is identical with the described height increasing side bar 1, thus construction can be made convenient, while also more attractive in appearance.
Preferably, strengthen in structure for the basement side bar controlling deformation of deep excavation above-mentioned, the depth-width ratio of described haunch bracket 2 can be 1:1-1:2.In the present embodiment, the depth-width ratio of described haunch bracket 2 is 1:2, thus the power transmission making to increase between side bar 1 and structure girder 4 is more steadily reliable.
Preferably, strengthen in structure at the above-mentioned basement side bar for controlling deformation of deep excavation, described in increase side bar 1 and join large hoop and be connected with described former design side bar 3, so not only can convenient construction, raising efficiency of construction.
Preferably, strengthen in structure above-mentioned for the basement side bar controlling deformation of deep excavation, please consult Fig. 2 by emphasis, increase in side bar 1 and structure girder 4 described in the main muscle 8 of described haunch bracket anchors into respectively, and anchor into length and be respectively 40d, d is the diameter of the main muscle 8 of described haunch bracket, thus can make haunch bracket 2 and connection between former design side bar 3 and structure girder 4 more firm.
Preferably, strengthen in structure for the basement side bar controlling deformation of deep excavation above-mentioned, described former design side bar 3 and described increasing between side bar 1 arrange reinforced mesh (not shown).By arranging reinforced mesh, facilitating and follow-uply cutting work to what increase side bar 1.Certainly, follow-up need cut influential side bar 1 of increasing.
Preferably, strengthen in structure above-mentioned for the basement side bar controlling deformation of deep excavation, the foundation ditch layer second from the bottom that described structure girder 4 is positioned at reverse construction.That is, in the present embodiment, when foundation ditch layer second from the bottom inverse does structure construction, foundation ditch is peripherally set up and increased side bar 1 in the below of the former design side bar 3 at wall 5 place, and the structure girder 3 vertical with former design side bar 3 is carried out haunch process namely haunch bracket 1 is set, 609 steel pipes for replacement floor tiltedly throw support.Described side bar 1, former design side bar 3, structure girder 3, haunch bracket 2 and the secondary beam 6 increased is built together and is formed, this construction technology not only simplifies difficulty of construction, and shorten the construction period greatly, better serve the effect controlling the wall lateral displacement distortion of deep foundation ditch ground.
Foregoing description is only the description to the utility model preferred embodiment; any restriction not to the utility model scope; any change that the those of ordinary skill in the utility model field does according to above-mentioned disclosure, modification, all belong to the protection domain of claims.
