Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete construction, and particularly relates to a high-efficiency well point temperature control device. Background Technique
[0002] In the ordinary well point dewatering process, when the well point pipes are arranged under the raft of the structure, the drain pipes need to pass through the raft of the structure to discharge water, leaving perforations on the raft of the structure, which affects the integrity of the concrete raft. At the same time, if the perforations are not sealed tightly, it is easy for groundwater to turn up through the holes into the interior of the structure, causing water seepage in the structure. For the mass concrete of the underground foundation raft of the structure, cooling water pipes are usually laid separately for temperature control, and external cooling water needs to be input. When the underground foundation raft of the structure involves the above two processes at the same time, different water pipes in the raft of the structure are vertically and horizontally staggered, affecting the construction quality. Content of the Utility Model
[0003] Aiming at the problems raised in the above background technique, the purpose of the utility model is to provide a high-efficiency well point temperature control device.
[0004] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0005] A high-efficiency well point temperature control device includes:
[0006] Mass concrete;
[0007] A temperature control device, including cooling water pipes embedded in the mass concrete. The water inlet end of the cooling water pipes is connected with well point drain pipes. The well point drain pipes are arranged in well holes. A water suction pump is connected to one side of the cooling water pipes, and a water outlet is provided at the output end of the cooling water pipes.
[0008] Further limited, a connecting pipe is provided between the cooling water pipes and the well point drain pipes. One side of the connecting pipe is communicated with the cooling water pipes, and a check valve is provided between the other side of the connecting pipe and the well point drain pipes. Such a structural design improves the connection effect and has an anti-backflow effect.
[0009] Further limited, a pressure valve is installed on the other side of the cooling water pipes, and a water replenishing port is provided outside the pressure valve of the cooling water pipes. Such a structural design is convenient for water replenishment.
[0010] The beneficial effect of the utility model is that the utility model combines well point dewatering and mass concrete temperature control into a complete set of systems, directly connects the low-temperature groundwater pumped out by well point dewatering into the cooling water pipes of the mass concrete for use as cooling water, saves water resources, reduces the number of water pipes embedded in the concrete structure, effectively improves the construction quality of concrete, and reduces the construction cost. Description of the Drawings
[0011] The present utility model can be further illustrated by the non-limiting embodiments given in the attached drawings;
[0012] Figure 1 It is a schematic structural diagram of an energy-efficient well point temperature control device according to an embodiment of the present utility model;
[0013] The main element symbols are explained as follows:
[0014] Mass concrete 1, cooling water pipe 2, well point dewatering pipe 3, suction pump 4, water outlet 5, connecting pipe 6, check valve 7, pressure valve 8, water replenishing port 9. Specific embodiments
[0015] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the attached drawings and embodiments.
[0016] As Figure 1 shown, an energy-efficient well point temperature control device of the present utility model includes:
[0017] Mass concrete 1;
[0018] The temperature control device includes cooling water pipes 2 embedded in the mass concrete 1. The water inlet end of the cooling water pipes 2 is connected to a well point dewatering pipe 3. The well point dewatering pipe 3 is arranged in a well hole. A suction pump 4 is connected to one side of the cooling water pipes 2, and a water outlet 5 is provided at the output end of the cooling water pipes 2.
[0019] Further defined, a connecting pipe 6 is provided between the cooling water pipes 2 and the well point dewatering pipe 3. One side of the connecting pipe 6 is communicated with the cooling water pipes 2, and a check valve 7 is provided between the other side of the connecting pipe 6 and the well point dewatering pipe 3. Such a structural design improves the connection effect and has an anti-backflow effect. In fact, other connection structural shapes of the cooling water pipes 2 and the well point dewatering pipe 3 can also be considered according to specific situations.
[0020] Further defined, a pressure valve 8 is installed on the other side of the cooling water pipes 2, and a water replenishing port 9 is provided outside the pressure valve 8 of the cooling water pipes 2. Such a structural design is convenient for water replenishment. In fact, other water replenishing structural shapes of the cooling water pipes 2 can also be considered according to specific situations.
[0021] In this embodiment, during use, an external water suction pump 4 applies negative pressure to the well point dewatering pipe 3 through the cooling water pipe 2 to pump out the groundwater in the well point dewatering pipe 3. The groundwater pumped out from the well point dewatering pipe 3 enters the cooling water pipe 2 through the connecting pipe 6 to cool the mass concrete 1. By adding a check valve 7 between the connecting pipe 6 and the well point dewatering pipe 3, the backflow of cooling water into the well point dewatering pipe 3 is prevented. Considering the unstable water output of the well point dewatering pipe 3, a water replenishing port 9 is added outside the cooling water pipe 2 to replenish water when the water volume of the well point dewatering pipe 3 is insufficient. To avoid a small pumping negative pressure in the well point dewatering pipe 3 caused by excessive water replenishment, which affects the dewatering effect, a pressure valve 8 is added to the water replenishing port 9. When the water volume in the cooling water pipe 2 is insufficient, the negative pressure increases, and the pressure valve 8 automatically opens for water replenishment. When the water volume in the cooling water pipe 3 is sufficient and the negative pressure decreases, the pressure valve 8 automatically closes to reduce water replenishment, while ensuring the dewatering effect and the cooling effect of the mass concrete 2.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
