Foundation pit supporting construction in the prior art is referring to shown in Fig. 7 comprising is fixedly arranged on the ring-like branch retaining wall of 1 inner wall of foundation pit 11, branch retaining wall 11 is equipped with fastening reinforcing bar 4, and the side wall of fastening reinforcing bar 4 is equipped with screw thread, and fastening reinforcing bar 4 is worn branch retaining wall 11 simultaneously Screw in the soil layer of 1 surrounding of foundation pit, fastening reinforcing bar 4 is located at one end in branch retaining wall 11 and is installed with limit plate 41, limit plate 41 and 11 inner wall of branch retaining wall fits.It realizes the connection with 1 outside soil layer of foundation pit by the screw thread of fastening reinforcing bar 4, and passes through limit Plate 41 realizes the Auxiliary support to branch retaining wall 11.
But the connection with 1 surrounding soil layer of foundation pit is only realized by the screw thread of fastening reinforcing bar 4, stability is poor, so that branch Retaining wall 11 is difficult to obtain stable Auxiliary support, and the compression strength so as to cause branch retaining wall 11 is lower, therefore to be improved.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of pattern foundation pit supporting structure knot that structural strength is high Structure, with the higher advantage of compression strength.
To achieve the above object, the present invention provides the following technical scheme that
A kind of foundation pit supporting construction that structural strength is high, the ring-like branch retaining wall including being fixedly arranged on foundation pit inner sidewall, in the foundation pit Portion is provided along its length several pressure rings, and several pressure rings are sequentially connected and are located in the same horizontal plane, the pressure Power ring end is fixedly connected with branch retaining wall inner wall, and attachment beam, the two sides point of the connection ring are equipped between the adjacent pressure rings Be not fixedly connected with two adjacent pressure rings, the both ends of the attachment beam be fixedly connected respectively with the two sides inner wall of branch retaining wall and It is perpendicular.
By using above-mentioned technical proposal, pressure rings are stably connected with branch retaining wall by attachment beam realization, pressure rings and company It connects beam and forms inner support component, and formed by concreting, compression strength is high.By pressure rings as main compression structure Part, when the soil layer of foundation pit surrounding applies the pressure of horizontal direction to branch retaining wall, circular pressure rings may make it to be pressed Stress more evenly, that is, may make pressure rings, supporting beam and attachment beam can integrally provide branch retaining wall to stablize support when power, compared to Traditional mode, compression strength are higher.
Further, several supporting beams are equipped between the pressure rings and branch retaining wall, several equal levels of supporting beam are set It sets, the both ends of several supporting beams are fixedly connected with pressure rings outer wall and branch retaining wall inner wall respectively.
By using above-mentioned technical proposal, supporting beam can increase the connective stability between pressure rings and branch retaining wall, pass through Supporting beam may make pressure ring-side wall to be attached everywhere with branch retaining wall, that is, may make the stress of pressure rings more evenly, so that Pressure rings are more stable to the support of branch retaining wall.
Further, support reinforcement planting is embedded in the supporting beam, the support reinforcement planting is backwards to one end of pressure rings It wears to branch retaining wall, the support reinforcement planting is installed with anticreep cone backwards to one end of pressure rings, and the anticreep cone is located at In branch retaining wall, the tip of the anticreep cone is backwards to pressure rings.
By using above-mentioned technical proposal, the anticreep cone of reinforcement planting end is supported to may make the supporting beam after pouring molding It is not easy to loosen with branch retaining wall, further improves the stability of supporting beam Yu branch retaining wall connection status.
Further, it is circumferentially with the pre- bar planting of pressure along it in the pressure rings, the support reinforcement planting is close to pressure rings One section of outside be equipped with fastening block, the fastening block is located in pressure rings, and the fastening block side wall is equipped with fastener hole, the branch Support reinforcement planting is threadedly coupled with fastener hole, and the fastening block bottom wall is equipped with the binding groove plugged for the pre- bar planting of pressure.
By using above-mentioned technical proposal, by support the fastening block of reinforcement planting end can be rapidly completed support reinforcement planting with The fastening of the pre- bar planting of pressure, rotation fastening block are adjusted position of the fastening block relative to support reinforcement planting, are adjusted to suitable position Afterwards, the pre- bar planting of pressure is plugged to binding groove, support reinforcement planting hereafter may make to be not easy along its axial and pre- bar planting of pressure It loosens, that is, may make the high stability between supporting beam and pressure rings.Further improve the resistance to compression of this case entirety Intensity.
Further, the binding groove inner wall is equipped with pin hole in the horizontal direction, and pin shaft, the pin are inserted in the pin hole The end of axis is protruded into binding groove and is located at below the pre- bar planting of pressure.
Pin shaft is plugged to pin hole after the pre- bar planting of pressure is plugged to binding groove by using above-mentioned technical proposal, And the end of pin shaft is extended in binding groove, so that pin shaft is connected to the lower section of the pre- bar planting of pressure, it can further limit pressure The pre- bar planting of power skids off binding groove, improves the stability after the pre- bar planting of pressure is plugged to binding groove.
Further, the pin shaft and pin hole clearance fit, the pin shaft outer wall are installed with elastic cushion, the elastic cushion with Pin hole interference abuts.
By using above-mentioned technical proposal, after pin shaft is plugged to pin hole, elastic cushion outer wall and pin hole inner wall keep one Constant-pressure, after by the maximum static friction force between elastic cushion outer wall and pin hole inner wall pin shaft being plugged to pin hole not Easily voluntarily skid off.
