Description

Technical Field

[0001] The present invention relates to the technical field of wind power tower foundation construction, and in particular to a wind power tower foundation construction device and method. Background Art

[0002] The main processes of wind turbine tower foundation construction include cleaning the topsoil, mechanical excavation, manual bottom cleaning, compaction, cushion construction and embedded parts installation, steel engineering machine anchor bolt assembly leveling, concrete maintenance and other steps, which are the basis for wind turbine installation. However, in the existing wind turbine tower foundation construction process, when the concrete is poured and formed, due to the large demand for concrete and the large number of internal structural layers of the steel bars, it is easy to cause uneven pouring and hollowing problems, which reduces the stability of the foundation; and in the process of concrete pouring, it is necessary to manually hold the concrete pouring pipe, move the pouring position, and pour evenly, which is easy to cause work fatigue; before installing the embedded parts, the embedded parts need to be leveled horizontally. Due to the large foundation pit and the large number of embedded parts, leveling the embedded parts one by one increases the construction difficulty and time, and it is difficult to quickly level the embedded parts; during the construction process, since it takes about a month to dry after pouring once, if there is a sudden bad weather, the quality of concrete molding is affected, and even a second pouring is required. The loss of construction is relatively large, and it is difficult to selectively perform a first molding pouring or a second molding pouring to reduce the loss. Summary of the invention

[0003] In view of this, the present invention provides a wind turbine tower foundation construction device and method to solve the problems of uneven pouring and easy hollowing, easy fatigue of holding the concrete pouring pipe, difficult and time-consuming leveling of embedded parts, and difficulty in selective primary or secondary molding and pouring during the foundation construction process.

[0004] The present invention provides a wind power tower foundation construction device, comprising: a foundation body and a pouring auxiliary part; the foundation body is formed by pouring concrete, the foundation body comprises an inner base, the interior of the inner base is pre-installed with built-in anchors and a main support member; the main support member comprises an embedded plate, the top surface of the embedded plate is provided with a horizontal leveling member; the built-in anchor member is installed inside the main support member, and a dividing pipe is installed inside the built-in anchor member; the pouring auxiliary part comprises a connecting frame, the top surface of the connecting frame is provided with a rotating support member; the rotating support member is composed of a connecting turntable and a grasping member, the grasping member is rotatably clamped on the top surface of the connecting turntable, and a concrete pouring pipe is clamped inside the grasping member.

[0005] Optionally, a connecting threaded hole is opened inside the built-in anchor, and an inclined steel bar is connected inside the connecting threaded hole. The inclined steel bar is connected to the bottom surface of the foundation pit. The inclined steel bar can be connected to the built-in anchor through the connecting threaded hole, thereby ensuring that the outer body and the inner base are fixed as one after pouring concrete.

[0006] Optionally, the bottom surface of the connecting turntable is clamped on the top of the connecting plate by rotating the axis, and the top surface of the connecting turntable is fixedly connected to a supporting plate by a round rod.

The circular hole provided at the bottom of the grip is penetrated by the round rod at the top of the connecting turntable, and gripping rings are welded on the left and right sides of the grip respectively. The interior of the grip is penetrated by the concrete pouring pipe. After the concrete pouring pipe is placed into the grip, when the concrete output pump is started for pouring, the operator can adjust the discharge port position of the concrete pouring pipe by gripping the two gripping rings, and the pouring position can be changed by rotating the grip, thereby achieving uniform pouring.

A connecting frame is fixedly welded to the end of the rod, and a clamping ring is sleeved on the front end cross bar of the connecting frame. A knocking rod is fixedly welded to the bottom of the clamping ring. When the concrete pouring pipe is pouring, the vibration of the concrete output pump will cause the concrete pouring pipe to vibrate. The rotating support will drive the connecting frame to vibrate synchronously, which will drive the knocking rod to vibrate, and the knocking rod will knock on the steel frame, so that the concrete can settle better during the pouring process, avoid accumulation in one place and cause internal hollowing, and ensure the internal forming of the foundation body.

[0014] 2) Determine the pouring center point of the foundation body, set up a steel frame, and place the embedded plate around the center point. After the horizontal leveling piece is connected through the connector and the connecting pipe, it is placed on the top surface of the embedded plate, and the embedded horizontal pipe is used to perform horizontal leveling of the embedded plate;

[0015] 3) Weld the connecting steel bar to the top surface of the embedded plate, fasten the top of the connecting steel bar to the connecting ring, and fix the connecting sleeve inside the connecting ring;

[0016] 4) Pre-install steel bars inside the outer body and the inner base, connect the inclined steel bars inside the threaded holes on the built-in anchors, and connect the inclined steel bars to the bottom of the foundation pit;

[0019] Beneficial Effects

[0020] According to a wind power tower foundation construction device of each embodiment of the present invention, compared with a traditional construction device, when the concrete pouring pipe is poured, the vibration of the concrete output pump will cause the concrete pouring pipe to vibrate, and the rotating bracket will drive the connecting frame to vibrate synchronously, which will drive the knocking rod to vibrate, and the knocking rod will knock the steel frame, so that the concrete can settle better during the pouring process, avoiding accumulation in one place and causing internal hollowing, and ensuring the internal forming of the foundation body;

[0021] In the process of using the pouring auxiliary parts, the clamping cone can be used to clamp the hydraulic cylinder to the steel frame, thereby improving the stability of the pouring auxiliary parts. In the pouring process, the position of the concrete pouring pipe can be stably supported, so there is no need to hold the concrete pouring pipe for pouring, which reduces the labor required for construction;

[0022] In addition, after the connector is connected to the next connector pipe through threaded engagement, the horizontal leveling piece can form a complete circular structure, and the connection between the connector and the connector pipe is clamped in the middle section of the top clamping groove, which can limit and fix the connection between the connector and the connector pipe, and at the same time, all embedded plates can be horizontally leveled, so there is no need to calibrate the horizontal position one by one, which improves the efficiency of calibrating the embedded plates and shortens the time.

[0023] In addition, when starting the concrete output pump for pouring, the operator can adjust the outlet position of the concrete pouring pipe by grasping the two grasping rings, and the pouring position can be changed by turning the grasping piece, so as to achieve uniform pouring and reduce the fatigue of the operator caused by the over-sinking of the concrete pouring pipe;

[0024] In addition, when choosing to use separator pipes, the inside of the built-in anchor can be molded first, and the steps of concrete pouring and drying time can be controlled in steps. Under special conditions such as the need for additional reinforcement of anchor rods, sudden heavy rains, tornadoes and other severe weather conditions, step-by-step molding can better reduce the losses caused by emergencies during construction.
