The embodiment of the application provides a double row pile supporting construction of foundation ditch, it can solve among the relevant art to stable row pile have the problem of certain restriction.
In order to solve the technical problem, the application provides a double-row pile supporting structure of a foundation pit, which comprises a first row of piles 1, a second row of piles 2, a bracket 3, a steel beam 4 and a pushing mechanism 5,
the first row of piles 1 are arranged to be close to the inner wall of the foundation pit and support the foundation pit; the second row of piles 2 is arranged on the inner side of the first row of piles 1; the bracket 3 is horizontally arranged between the first row of piles 1 and the second row of piles 2 and used for supporting the first row of piles 1 and the second row of piles 2; the steel beam 4 is arranged on the bracket 3 and is attached to the first row of piles 1; the pushing mechanism 5 is arranged on the bracket 3 and used for pushing the steel beam 4 to support the first row of piles 1 and applying supporting force to the first row of piles 1.
In this application, first campshed 1 and second campshed 2 lie in same one side of foundation ditch, and under general conditions, first campshed 1 and second campshed 2 are vertical setting to level sets up bracket 3 between first campshed 1 and second campshed 2, support through bracket 3 and hold first campshed 1 and second campshed 2.
Because of the geological relation of foundation ditch, at the in-process of campshed protection, the possibility of empting that first campshed 1 exists, and topple over toward the direction of foundation ditch, make the foundation ditch warp, consequently in this application, set up girder steel 4 and pushing mechanism 5 on bracket 3, promote girder steel 4 through pushing mechanism 5, make girder steel 4 support and hold first campshed 1, provide the pretightning force, can prevent that first campshed 1 from warping, and it can understand that, the driving force that provides of pushing mechanism 5 can set up according to actual conditions, for example, when the angle that first campshed 1 will incline is very big, pushing mechanism 5 can provide more driving forces and keep first campshed 1 in vertical state.
Further, pushing mechanism 5 is including flexible end and stiff end, flexible end with the stiff end is connected, the stiff end with second row pile 2 is connected, flexible end relatively stiff end is close to or keeps away from, and works as flexible end is kept away from during the stiff end, flexible end is used for supporting and holds first row pile 1, can be right first row pile 1 and girder steel 4 exert the holding power.
Preferably, the pushing mechanism 5 is a hydraulic device, and the hydraulic device includes a hydraulic cylinder and a hydraulic rod, the hydraulic cylinder forms the fixed end, and the hydraulic rod forms the telescopic end.
Because hydraulic means's one end and 2 fixed connection of second campshed, the other end is used for supporting and holds girder steel 4, is supporting the in-process of holding girder steel 4, can give a reaction force to hydraulic means stiff end for hydraulic means can guarantee that first campshed 1 and second campshed 2 can not have the possibility of empting simultaneously to first campshed 1 and second campshed 2, and then can prevent that the foundation ditch from warping.
Further, the second row of piles 2 includes a front row of piles 21, a rear row of piles 22, and a crown beam 23 connecting the front row of piles 21 and the rear row of piles 22, the front row of piles 21 being attached to the fixed ends.
In this application, the upper end of first campshed 1 and second campshed 2 all is provided with crown beam 23, and first campshed 1 and second campshed 2 all include very many rows of stake poles, in this application, first campshed 1 adopts single row structure, and what second campshed 2 adopted is double row pile structure, make the structure of second campshed 2 more stable, and owing to adopt double row structure, make its bending resistance stronger, make things convenient for pushing mechanism 5 to provide bigger thrust, refer to specifically fig. 2, and because pushing mechanism 5 can provide power to first campshed 1 and second campshed 2 simultaneously, consequently the figure of back campshed 22 will be less than the figure of preceding campshed 2.
It will also be appreciated that the number of rows of pile elements in the first row of piles 1 exceeds the number of rows of pile elements in the preceding row of piles 2, mainly because the first row of piles 1 is mainly subjected to forces by which the soil is pressed in the direction of the foundation pit.
In the present application, the section of the steel beam 4 is "H" shaped, and/or the steel beam 4 is provided with a reinforcing rib plate 6.
In an ideal situation, if the inside of the steel beam 4 is a solid structure, but the thrust force of the thrust mechanism 5 and the supporting force of the bracket 3 are considered, because the section of the steel beam 4 is "H" shaped, the steel beam 4 is not only light in weight, but also strong in bending resistance and not easy to deform, and further, in order to improve the bending resistance of the steel beam 4, a reinforcing rib plate 6 is provided on the steel beam 4.
Specifically, bracket 3 includes diaphragm 31 and the riser 32 of vertical setting that the level set up, diaphragm 31 is connected with riser 32, and wherein diaphragm 31 is used for supporting girder steel 4 and pushing mechanism 5, riser 32 laminating is in on the first row of stake 1, and with 1 fixed connection in the first row of stake.
Referring to fig. 1, the whole bracket 3 is in an "L" shape, the horizontal plate 31 is used for supporting the steel beam 4 and the pushing mechanism 5, and also has the function of supporting the first row of piles 1 and the second row of piles 2, the vertical plate 32 has the function of supporting the horizontal plate 31, the horizontal plate 31 and the vertical plate 32 are generally connected in a welding manner, and when the first row of piles 1 have the possibility of toppling over, the vertical plate 32 and the horizontal plate 31 also have a certain interference function.
Furthermore, because the stress of the L-shaped structure is uneven, the reinforcing part 7 is connected between the transverse plate 31 and the vertical plate 32, and the reinforcing part 7 can be a steel plate, a steel rod or other structures in the prior art, as long as the reinforcing part can enhance the strength of the bracket 3, so that the bracket is prevented from deforming.
Further, a fine stone concrete layer 8 is filled between the first row of piles 1 and the steel beams 4.
Generally, what first row of stake 1 adopted is the round bar, and its and girder steel 5's contact surface is less, and in this application, through filling with the pea gravel concrete, the contact surface of first row of stake 1 with girder steel 5 has been increased in other words for first row of stake 1 atress is more even.
In practice, since the steel beam 4 is required to support the first row of piles 1, and in order to prevent the steel beam 4 from deforming, the strength of the steel beam 4 itself needs to be hard, which makes the steel beam 4 have a certain weight, and the strength of the bracket 3 is limited, in this application, a pre-tensioning system 9 is further included, and one end of the pre-tensioning system 9 is connected to the first row of piles 1, and the other end is connected to the upper end of the steel beam 4.
By means of the pretensioning system 9, the pretensioning system 9 can be made to pull the steel beam 4 from the upper end, i.e. to give the steel beam 4 a certain pretension, thereby relieving the bearing pressure of the corbel bracket 3.
Further, the pretensioning system 9 comprises a fixing member 91, a turnbuckle 92 and two hook-shaped members 93, wherein the fixing member 91 is fixed on the first row of piles 1, one of the two hook-shaped members 93 is hooked on the fixing member 91, and the other hook-shaped member is hooked on the upper end of the steel beam 4.
The hook 93 can be an "S" hook, and the material of the entire pretensioning system 9 is easily available and is easily replaceable.
