Above-mentioned dewatering well protective device 10 expands precipitation by the way that support pile 100 is arranged close to the side of road in dewatering well 1
Excavation face near well 1, reduces dynamic load, such as influence of the roadside wagon flow to dewatering well 1, then at the top of dewatering well 1 and
The first anchor ear 110 is arranged in bottom, and multiple second anchor ears 120 are arranged between the first anchor ear 110 of top and bottom so that drop
Well 1 is located in the protection network that the first anchor ear 110 and the second anchor ear 120 are formed, when in the case where being subject to external force, the first anchor ear
110 and second anchor ear 120 dewatering well 1 can be limited in protection network so that stable connection between the pipe of cement of dewatering well 1,
Dewatering well 1 is avoided there is a phenomenon where faulting of slab ends and is tilted, the safety of foundation pit construction is improved.
As shown in Fig. 2, dewatering well protective device 10 includes two the first anchor ears 110, a top for being located at dewatering well 1,
That is, close to the place that dewatering well 1 is open.Another is located at the bottom of dewatering well 1.In the present embodiment, the first anchor ear 110 is steel
Ring is sleeved on the outer wall of dewatering well 1.Further, in the present embodiment, the internal diameter of the first anchor ear 110 is equal to the outer of dewatering well 1
Diameter.When the first anchor ear 110 is set in the outer diameter of dewatering well 1, the outer wall of dewatering well 1 can be close to so that when arranging second
After anchor ear 120, the safeguard structure that the first anchor ear 110 and the second anchor ear 120 are formed can be close to the outer wall of dewatering well 1, and then limit
The misalignment or tilting of 1 pipe of cement of dewatering well processed.In other embodiments, the internal diameter of the first anchor ear 110 can also be slightly less than precipitation
The outer diameter of well 1.
Second anchor ear 120 is located between two the first anchor ears 110, one end of the second anchor ear 120 and first armful of top
First anchor ear 110 of 110 connection of hoop, the other end and bottom connects.Multiple second anchor ears 120 are set along the perimeter of the first anchor ear 110
It sets and is evenly distributed between two the first anchor ears 110.In the present embodiment, the second anchor ear 120 is perpendicular to 110 institute of the first anchor ear
Plane.That is, the first anchor ear 110 and the second anchor ear 120 form a frame, it is sheathed on dewatering well 1, due to the first anchor ear
The distance between 110 and dewatering well 1 are smaller so that entire the distance between frame and dewatering well 1 are also smaller, that is, frame is basic
It is the movement or inclination be close to dewatering well 1, and then limit dewatering well 1, thus it is guaranteed that being connected between 1 pipe of cement of dewatering well
Stability, avoid dewatering well 1 dislocation and inclination and cause silt to enter downcomer, improve the safety of construction.At this
In embodiment, the second anchor ear 120 is reinforcing bar.Reinforced steel bar strength is big and is unlikely to deform, and is connected between raising 1 pipe of cement of dewatering well steady
It is qualitative.In other embodiments, the second anchor ear 120 or bamboo cane.
