Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.
As shown in fig. 1-2, the foundation pit external corner supporting structure comprises a ground connecting wall 2, a snap pile 1, a waist beam 6, a crown beam 3 and a counter-pulling assembly 4.
The occluding piles 1 are arranged in three rows, wherein two rows are parallel to each other and vertical to the ground connecting wall 2; the other row is arranged between the two rows of parallel occluding piles 1, and the three rows of occluding piles 1 are sequentially vertical; the outside of the occluding pile 1 is provided with a corner connecting wall which is occluded with the occluding pile, the occluding pile 1 and the corner connecting wall which is occluded with the occluding pile form a three-sided occluding pile wall with a right angle, namely, the corner of the three-sided wall is formed.
The external corner ground connection wall meshed with the meshed pile 1 is provided with a crown beam 3, three waist beams 6 are arranged below the crown beam 3 at intervals, and the three waist beams 6 are respectively arranged at 1.5m, 4m and 6m below the crown beam 3.
The corner of the external corner wall 2 and the corner of the external corner wall 2 which are meshed with the meshed piles 1 and are parallel to each other are respectively provided with a counter-pulling component 4.
The opposite pulling assembly comprises an anchor cable 5, a steel backing plate 9, a support 7 and a lock 8. Wherein, between the ground continuous walls 2 at external corners parallel to each other, the anchor cable 5 is vertically connected between the corresponding waist beams 6, the anchor cable 5 sequentially passes through the waist beams 6, the steel backing plates 9 and the support 7, and the tail ends are locked by the locks 8; at the corner of the external corner underground diaphragm wall 2, the anchor cable 5 is connected with the underground diaphragm wall 2 at an angle of 45 degrees. The anchor cable 5 is connected to the waist rail 6, whether parallel or corner.
The external corner structure of the foundation pit and the opposite-pulling assembly 4 connected between the ground continuous walls 2 at the external corners can strengthen the external corners and ensure the structural stability of the external corners. The steel backing plate 9 can disperse the concentrated force acting on the waist beam 6 when the anchor cable 5 is tensioned. The support 7 and the lock 8 can improve the continuous and even stress of the anchor cable 5, and play a role in preventing stress loss to a certain extent.
The construction process of the utility model (as shown in figure 3):
