Abstract
The utility model belongs to the technical field of freezing consolidation stratum construction, particularly relates to a freezing pipe removing device, and aims at removing a freezing pipe conveniently and rapidly on the premise that the consolidation effect of a stratum is not lowered basically, guaranteeing the consolidation effect and engineering quality, and enabling construction to be convenient, rapid and safe. The freezing pipe removing device comprises a clamping plate and a plurality of lifting jacks, wherein the clamping plate comprises two symmetrical lifting plates, a connection section I and a connection section II of the two lifting plates are respectively connected through pressing bolts, the plurality of lifting jacks are arranged between the clamping plate and a freezing soil layer, and the lifting jacks are symmetrically arranged relative to the axis of the freezing pipe. The freezing pipe removing device has the advantages of effectively shortening heat circulation time, improving work efficiency, guaranteeing freezing quality, being convenient and rapid to use, avoiding the auxiliary work of repeated installation of a scaffold, having low requirements for work space, being strong in applicability, being convenient to apply and popularize in a wide range, and being obvious in economic effects and social benefits.
Description
Technical field
The utility model belongs to the technical field of consolidation by freezing stratum construction, is specifically related to a kind of freezing pipe plucking device.
Background technology
The removal method of freezing pipe mainly contained after the construction of existing consolidation by freezing stratum was finished:
The method of Long Time Thermal circulation.This is the method that a kind of freezing pipe at present commonly used is pulled out, that is, after frozen construction is finished, utilize hot salt brine to circulate in frigo, frozen soil around the freezing pipe is fully melted after, the beginning tube drawing.The main drawback of this method is just can tube drawing after the soil layer that freezed around the freezing pipe needs to melt fully in actual mechanical process, Frozen Soil melting layer scope is large like this, thawing time is long, and heat to melt the time long, will the large tracts of land dissipate heat, so that the consolidation by freezing effect of soil layer reduces greatly.Do not guarantee consolidation effect when causing the great amount of cost waste.Cause great potential safety hazard for follow-up construction.
Summary of the invention
Goal of the invention of the present utility model: under the prerequisite of the consolidation effect that does not substantially weaken the stratum, pull out quickly and easily freezing pipe, when guaranteeing consolidation effect and workmanship, so that convenient and quick construction safety.
The utility model adopts following technical scheme to realize:
A kind of freezing pipe plucking device, it is characterized in that comprising clamp plate and some jack, described clamp plate comprises the raising plate of two symmetries, the inboard of two raising plates comprises the linkage section I that links to each other successively, arc gripping section and the linkage section II that is used for the clamping freezing pipe, the upper and lower projection that all is provided with of linkage section I, arc gripping section and the relative raising plate of linkage section II, the linkage section I of two raising plates is connected by hold-down bolt with the linkage section II and is connected, some jack are arranged at the clamp plate and freeze between the soil layer, and the relative freezing pipe of each jack axle center is symmetrical arranged.
The freezing pipe removal method that uses the utility model to finish, step is as follows: after freezing to finish, carry out first brine recycling and thawed 5 ~ 10 minutes, then utilize the clamp plate to fix stuck freezing pipe termination, each jack rises the top synchronously, progressively outwards extracts freezing pipe, until whole freezing pipe is all extracted.
The utlity model has following beneficial effect: effectively reduced the thermal cycle time, the heat time of melting reduced to 5 ~ 10 minutes by original 20 ~ 30 minutes, when having improved operating efficiency, quality is freezed in assurance, prevented that effectively heat from spreading in freezing body, effectively guaranteed to freeze the quality of freezing of body, the utility model is convenient to use simultaneously, avoid repeating to set up the less important works such as scaffold, working space requires little, strong adaptability, high efficiency, the side is all over large-area applications and popularization, and economic benefit and social benefit are fairly obvious.

Fig. 1 is structural representation of the present utility model,
Fig. 2 is the schematic diagram that the utility model is used for vertical tube drawing operation,
Fig. 3 is the schematic diagram that the utility model is used for horizontal tube drawing operation,
Among the figure: the 1-freezing pipe, the 2-jack, the 3-raising plate, the 4-hold-down bolt, 5-linkage section I, 6-arc gripping section, 7-linkage section II, 8-freezes soil layer.
The specific embodiment
The freezing pipe plucking device, comprise clamp plate and some jack 2, jack is at least two, described clamp plate comprises the raising plate 3 of two symmetries, the inboard of two raising plates 3 comprises the linkage section I 5 that links to each other successively, the arc gripping section 6 and the linkage section II 7 that are used for clamping freezing pipe 1, linkage section I 5, arc gripping section 6 and linkage section II 7 relative raising plates upper, the lower projection that all is provided with, the linkage section I 5 of two raising plates is connected with the linkage section II respectively by hold-down bolt 4 connections, some jack 2 are arranged at the clamp plate and freeze between the soil layer 8, and the relative freezing pipe of each jack axle center is symmetrical arranged.
The freezing pipe removal method that uses the utility model to finish, step is as follows: after freezing to finish, carry out first brine recycling and thawed 5 ~ 10 minutes, then utilize the clamp plate to fix stuck freezing pipe termination, each jack rises the top synchronously, progressively outwards extracts freezing pipe, until whole freezing pipe is all extracted.Pull out the elevation of vertical and horizontal frozen pipe respectively as shown in Figures 2 and 3.
