Specific implementation mode
As shown in Figs. 1-2, dewatering well 1 includes the second side close to the first side of road 2 and separate road, an embodiment Dewatering well protective device 10 includes support pile 100, at least two first anchor ears 110 and multiple second anchor ears 120, support pile 100 Positioned at the first side of dewatering well 1, at least two first anchor ears 110 are sheathed on the top and bottom of dewatering well 1, the second anchor ear respectively 120 along dewatering well 1 short transverse be arranged, the second anchor ear 120 is between the first anchor ear 110 and along first anchor ear 110 Perimeter setting, the both ends of the second anchor ear 120 are connect with the first anchor ear 110 respectively, between the second anchor ear 120 and dewatering well 1 Distance is less than the distance between support pile 100 and dewatering well 1.
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.
Please refer to Fig. 1, Fig. 3 and Fig. 4, dewatering well 1 includes the second side close to the first side of road and separate road, Support pile 100 is located at the first side of dewatering well 1.That is, support pile 100 is located at dewatering well 1 close to the side of road, support pile 100 Excavation face can be expanded, reduce influence of the roadside wagon flow to downcomer.In the present embodiment, support pile 100 includes more supportings Reinforcing bar.More reinforcing bars form a supporting mesh, reduce influence of the dynamic load on road to dewatering well 1.Wherein, support pile 100 Shape matched with the shape of excavation face.For example, when excavation face is arc, the shape of support pile 100 is also arc.In addition, The distance between second anchor ear 120 and dewatering well 1 are less than the distance between support pile 100 and dewatering well 1.That is, in dewatering well 1 Around two layers of protection of setting, one layer is support pile 100, another layer be the first anchor ear 110 and 120 property of the second anchor ear at frame, Ensure the stability of dewatering well 1.
In the present embodiment, dewatering well 1 includes multiple downcomers, and downcomer is tongue and groove downcomer.Dewatering well 1 is by multiple Downcomer is arranged to be formed successively, can facilitate the splicing of downcomer using tongue and groove downcomer, improves the efficiency that dewatering well 1 makes.
Please continue to refer to Fig. 1, in the present embodiment, dewatering well protective device 10 further includes prestress anchorage cable 130, prestressing force Anchor cable 130 is arranged close to the region of dewatering well 1.Prestress anchorage cable 130 is by drilling through soft stratum or sliding surface, one end It is anchored in hard rock stratum, then in another free end tensioning, to apply pressure in turn to unstable rock mass to rock stratum It is anchored.In the present embodiment, 130 one end of prestress anchorage cable is anchored on the outer wall of foundation pit, wherein prestress anchorage cable 130 Ontology be proximate to the region of setting dewatering well 1 and eliminate the shakiness of rock stratum to being anchored to the region near dewatering well 1 It is fixed that dewatering well 1 is impacted.
In addition, in order to ensure the stability of dewatering well 1, it, can be in dewatering well 1 close to road side during slope excavating Expand excavation face, and expand the branch mask of support pile 100, further decreases influence of the roadside wagon flow to dewatering well 1.In addition, The bell and spigot depth of 1 pipe of cement of socket joint dewatering well can also be increased, improve the stability of 1 pipe of cement of dewatering well connection.
Above-mentioned dewatering well protective device 10 reduces influence of the dynamic load to dewatering well 1 using support pile 100, using first armful Hoop 110 and the second anchor ear 120 solve the problems, such as easy fracture at 1 side slope of dewatering well, while being eliminated using prestress anchorage cable 130 Influence of the unstable formation to dewatering well 1.Therefore, using 1 stable connection of dewatering well of above-mentioned dewatering well protective device 10, it is ensured that Foundation pit structure safety, ensure that effective progress of precipitation process.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, it is all considered to be the range of this specification record.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But therefore it can not be interpreted as the limitation to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
