[0001] The utility model relates to the technical field of inverted well construction, in particular to a well wall concrete pouring device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In municipal drainage pipe network projects, open excavation construction is relatively difficult in residential areas, busy roads and many underground pipelines; while pipe jacking construction can minimize the impact on the surrounding environment. Caissons and inverted wells are the most common structures in pipe jacking projects. During construction, the well body is protected by a reverse construction method from top to bottom, which makes it difficult to pour concrete for the lower protective wall. At present, the common method is to pour concrete from the wellhead downwards. However, as the well depth will become deeper and deeper with the progress of construction, the deeper well depth will cause the concrete to segregate due to the large height difference when it falls, and the flexibility during pouring is not strong. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figures 1 to 3 .

[0029] The utility model discloses a well wall concrete pouring device, comprising:

[0030] A support 1 is erected on the top of the wellhead;

[0031] A hopper 2 is arranged on the support 1 and can be displaced on the support 1, and is used to receive concrete;

[0032] The limiting member 3 is used to limit the relative position of the hopper 2 and the bracket 1;

[0033] A conveying pipe 4 is connected to the discharge port of the hopper 2 and is used to guide the concrete to the designated area; and

[0034] The pulling component 5 is used to pull the conveying pipe 4 at the discharge port upwards and can move together with the hopper 2.

[0035] In the specific implementation, the bracket 1 is erected at the wellhead of the inverted well or the caisson, and then the position of the hopper 2 is adjusted, and then the relative position of the hopper 2 and the bracket 1 is limited by the limiter 3, and the feed pipe 4 of corresponding length is selected according to the well depth, and then the feed pipe 4 is connected to the discharge port of the hopper 2, and at the same time, the part of the feed pipe 4 close to the discharge port is connected to the pulling component 5, and then concrete can be input into the hopper 2. Workers can operate the feed pipe 4 to move the feed pipe 4 to the area and part that needs to be poured. The concrete slides down along the feed pipe 4 to prevent segregation caused by large height differences of the concrete, and the position of the feed pipe 4 can be adjusted within the radius of the feed pipe 4 for pouring, and can be poured at a certain local position, with greater flexibility during pouring.

[0036] In the present invention, the setting of the pulling component 5 can prevent the force on the feeding pipe 4 (including its own gravity and the force generated when the concrete goes down) from being fully transmitted to the discharge port of the hopper 2, thereby preventing the feeding pipe 4 from being separated from the hopper 2. At the same time, the pulling component 5 can move with the hopper 2, thereby ensuring the flexibility of the hopper 2 and facilitating the input of concrete into the hopper 2.

[0037] Preferably, the feed pipe 4 is a steel hose.

[0038] In one embodiment, the bracket 1 is arranged at the top of the wellhead in a rectangular shape, rolling grooves 11 are arranged on two opposite sides of the rectangular bracket 1, and rolling wheels 21 capable of rolling in the rolling grooves 11 are arranged on both sides of the corresponding rolling grooves 11 of the hopper 2. With this design, since the working environment is poor during the pouring of concrete, only the rolling cooperation between the rolling wheels 21 and the rolling grooves 11 can work stably and permanently under such working conditions.

[0039] In a specific implementation, the bracket 1 can be directly placed on the wellhead of a hanging well or a caisson, or the bracket 1 can be fixed on the wellhead by pre-embedded bolts, or the bracket 1 can be fixed by driving expansion screws on the top of the wellhead.

[0040] In one embodiment, a limiting block 22 is provided on one side of the hopper 2, a first limiting hole 23 is provided on the limiting block 22, a plurality of second limiting holes 12 are provided at the position of the bracket 1 corresponding to the limiting block 22, and the second limiting holes 12 are arranged at intervals along the moving direction of the hopper 2, and the limiting member 3 is inserted in the first limiting hole 23 and the corresponding second limiting hole 12. Preferably, the limiting member 3 may be a pin or a bolt.

[0041] In one embodiment, the outlet of the hopper 2 is provided with a rotating drum 24, and the delivery pipe 4 is sleeved on the rotating drum 24. With this design, when the worker drives the delivery pipe 4 to move, there is no need to worry about the torsion amplitude between the delivery pipe 4 and the hopper 2 being too large, and the resistance of the delivery pipe 4 when moving can also be reduced.

[0042] In one embodiment, an annular guide rail 6 is provided at the bottom of the hopper 2, and the pulling component 5 is slidably arranged on the annular guide rail 6. With this design, when a worker moves the material conveying pipe 4, the pulling component 5 can also slide on the annular guide rail 6 driven by the material conveying pipe 4, thereby avoiding interference between the pulling component 5 and the material conveying pipe 4.

[0043] In one embodiment, a supporting plate 25 connected to the hopper 2 is disposed on the outside thereof, the supporting plate 25 is located above the bracket 1, and the rolling wheel 21 is installed at the bottom of the supporting plate 25;

[0044] The annular guide rail 6 is located below the bracket 1, and is connected to the bearing plate 25 through a plurality of connecting columns 61, so that the bearing force is transmitted to the bracket 1 through the bearing plate 25. With this design, the forces on the annular guide rail 6 and the hopper 2 are respectively transmitted to the bracket 1 through the bearing plate 25, and the annular guide rail 6 and the hopper 2 do not interfere with each other and do not affect each other, and the load of the hopper 2 will not be increased.

[0045] In one embodiment, the pulling component 5 includes a slider 51 slidably arranged at the bottom of the annular guide rail 6, a first rope 52 connected to the slider 51, a buffer 53 arranged at the bottom end of the first rope 52, a second rope 54 connected to the buffer 53, and a connecting sleeve 55 arranged at the bottom end of the second rope 54, and the connecting sleeve 55 is used to connect to the conveying pipe 4.

[0046] In specific implementation, the setting of the buffer 53 can buffer the force on the feed pipe 4, which is convenient for the staff to work for a long time. At the same time, since the buffer 53 is set between the two ropes, the first rope 52 is directly connected to the slider 51, which will make it easier to drive the slider 51 to slide at the bottom of the annular guide rail 6.

[0047] It should be pointed out that the buffer is a tension buffer, and its specific structure has long been disclosed and is common knowledge to those skilled in the art, so it will not be described here. In addition, the connecting sleeve is divided into two left and right semicircular sleeves, which are connected together by bolts and clamped in the corresponding part of the conveying pipe.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0049] It should be noted that if the utility model embodiment involves directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
