Problems solved by technology

Due to the frosting and binding of the inlet pipe port, the high-pressure rubber hose is often not easy to disassemble. In order to speed up the construction, the high-pressure rubber hose is often sawn off and replaced, resulting in waste of materials, labor and working hours

Embodiment Construction

[0022] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0023] Such as figure 2 As shown, the freezer used for longitudinal temperature measurement includes a bypass pipe 1, a first gate valve 2, a return pipe 3, a water inlet pipe 4 and a freezer head 5, and the first gate valve 2 is installed in the bypass pipe 1, the bypass pipe 1, the return pipe 3 and the water inlet pipe 4 are respectively connected to the head of the freezer 5 and are in fluid communication; the water inlet pipe 4 is composed of a straight pipe 41 and a side pipe A tee pipe composed of pipes 42; a seco...

Abstract

The invention discloses a longitudinal temperature measurement freezing apparatus and method. The freezing apparatus comprises a by-pass pipe, a first gate valve, a water return pipe, a water inlet pipe and a freezing apparatus head. The first gate valve is mounted on the by-pass pipe. The by-pass pipe, the water return pipe and the water inlet pipe are connected with the freezing apparatus head and communicate with the freezing apparatus head in a fluid mode. The water inlet pipe is a three-way pipe composed of a straight pipe and a side pipe. A second gate valve is mounted on the straight pipe. When longitudinal temperature measurement is conducted through the freezing apparatus, only a water inlet valve and a water return valve need to be closed and a gate valve at the top of the water inlet pipe needs to be opened, operation is convenient and rapid, and waste of brine and rubber pipes is avoided.

Description

technical field [0001] The invention relates to equipment in the construction of coal mine shaft freezing engineering. More specifically, it relates to a freezer for longitudinal temperature measurement. Background technique [0002] At present, in the construction of shaft freezing engineering in coal mines, the determination of whether the frozen wall crosses circles is often based on the data of hydrological observation holes and temperature observation holes. However, some shafts cannot be constructed with hydrological observation holes or the setting of hydrological observation holes is unreasonable, resulting in incorrect water levels reported by hydrological holes. Accurate, so the role of the temperature measuring hole is even more important. According to the construction code of coal mine shaft freezing engineering, "the number of temperature measuring holes in each well should not be less than 3, 4, and 5 when the single-ring holes, double-ring holes, and three-ri...
