A guide tube driven by a chain driving device is arranged on a tower frame; the plastic water drainage plate penetrating through the guide tube can be inserted into the ground with the guide tube; the tower frame is provided with a depth measuring device for measuring the range of the water drainage plate, and the depth measuring device is connected with a recorder. By adopting the device for monitoring depth, the depth of the plastic water drainage plate inserted into the ground can be effectively monitored, and the construction quality can be ensured to meet the design requirement.

Description

The depth monitor of Plastic Drain Slab Construction

The utility model relates to a kind of depth monitor of Plastic Drain Slab Construction of reinforcing soft ground.

Consolidation Effect through Plastic is the common method of reinforcing subgrade in the building trade.This method is to have the plastic slat of vertical shallow trench to insert in the weak soil on the surface with board-plugging device, loads precompressed (or vacuum preloading) then on the ground, and the water in the weak soil is overflowed along the passage of plastic plate, thereby makes ground get rid of moisture content and reinforced.With this method Ground Treatment, the plastic plate that plastic plate inserts the degree of depth of weak soil and the insertion density of arranging in the ground scope of handling has very big influence to workmanship.Not enough or arrange too thinly as the plastic plate insertion depth, can not get rid of moisture content in the basic soil by designing requirement, then this ground is failed to reinforce effectively and is that building operations after reinforcing brings hidden dangers in project.The insertion depth of band drain still lacks a kind of effective supervising device during at present to Plastic Drain Slab Construction.If unit in charge of construction takes place for saving man-hour and material, make the insertion depth of band drain not reach designing requirement, for want of simple measuring means then may have a strong impact on workmanship, cause heavy economic losses.

The purpose of the utility model is to provide a kind of device that can monitor the insertion depth of band drain in the band drain work progress effectively, reaches designing requirement to guarantee construction, eliminates hidden danger of quality.

The depth monitor of Plastic Drain Slab Construction described in the utility model, the conduit that is promoted by chain drive is housed on the pylon, the plastic draining board that penetrates in the conduit can insert underground with conduit, the degree of depth determinator that can measure the band drain stroke is housed on pylon, and degree of depth determinator links to each other with recorder.

Degree of depth determinator can be a friction pulley, and friction pulley is fixed on the pylon, and its edge is close to conduit or plastic draining board.

Degree of depth determinator can be a ratchet, and ratchet is fixed on the pylon, and the ratchet of ratchet contacts with chain.

Degree of depth determinator can be the emission and the receiver of ray.Transmitter and receiver are fixed on the pylon, and are in the chain both sides respectively.

The depth monitor of Plastic Drain Slab Construction described in the utility model can be measured band drain to underground mobile stroke in work progress, rotate when band drain moves down as friction pulley or ratchet thereupon, and with the displacement of the form performance band drain that rotates, the emission of ray and receiver can be measured the joint number by the chain of transmitter in the chain both sides, multiply by the displacement that pitch can show band drain with joint number, thereby can measure the degree of depth that band drain inserts ground.As depth data is made record in work progress, this record is exactly the test basis of construction quality, the band drain insertion depth that both can reflect a certain station can be reflected in the total length of the scope internal consumption band drain of consolidated subsoil again, can draw the arrange density of band drain in this territorial scope.As long as guarantee the accuracy of depth survey data in the work progress, just can guarantee that construction quality reaches designing requirement, thereby eliminate hidden danger of quality.

Fig. 1 depth monitor described in the utility model.

Embodiment one

Pylon 1 both sides are equipped with by 2, two chain 2 synchronized movement of chain of drive power source and with the briquetting 4 on conduit 3 tops and are connected, and conduit 3 is the flat metal tubes that can insert band drain 5, and the band drain 5 of coiling penetrates from conduit 3 tops with the stake point 6 of lower end and links to each other.Chain 2 rotation compressing conduits 3 and stake point 6 insert underground, and be underground thereby drive band drain 5 inserts, and conduit 3 is pulled out in chain 2 counter-rotatings, and band drain 5 and stake point 6 are stayed underground.Band drain stroke determinator 7 is friction pulley 7a, and friction pulley 7a is contained on the pylon 1, and its edge is close to conduit 3, and conduit 3 moves down, and friction pulley 7a rotates thereupon, and this rotation can output signal to recorder 8 record strokes.Recorder is a prior art, can be mechanical counter, friction pulley 7a output torque for example, and actuation counter writes down the stroke that its revolution is a conduit 3; Recorder 8 also can be a computer, and friction pulley 7a rotates the output signal of telecommunication, is promptly got the stroke of conduit by the computer counting.Band drain 5 is downwards synchronization-moving with conduit, and the stroke of record conduit is exactly the stroke that band drain 5 moves down.

For preventing not to be installed with the stroke that band drain 5 is recorded as conduit 3 no-load runnings mistake band drain 5 in the conduit 3, the emission of ray and the auxiliary monitoring device 9 that receiver is formed are housed respectively in band drain 5 running orbit both sides, be with or without band drain 5 between emission and the receiver, auxiliary monitoring device 9 will be exported different signals and give computer, make computer export the stroke of record conduit 3 under the condition that band drain 5 is arranged at auxiliary monitoring device 9.

Embodiment two

The edge that is packed in the friction pulley 7b on the pylon 1 is on the movement locus of band drain 5.Promptly directly measure 5 strokes of band drain, and need not auxiliary monitoring device 9, all the other are identical with embodiment one.

Embodiment three

Degree of depth determinator 7 fixing on the pylon 1 is ratchet 7c, and the ratchet of ratchet 7c contacts with chain 2.Chain 2 is made up of a plurality of chain links, and the connection lateral pin of each chain link will be stirred ratchet 7c and rotate output signal when motion.All the other are identical with embodiment one.

Embodiment four

Fixing degree of depth determinator 7 is emission and receiver 7d such as infrared rays emission and receivers of ray on the pylon 1, and its transmitter and receiver are contained in chain 2 both sides respectively.The connection lateral pin of each chain link will block infrared rays during the chain operation, infrared rays can be passed in space between lateral pin, and infrared receiver receives infrared rays, and signal is imported the stroke that chain 2 could be measured and write down to computer, be the stroke of band drain 5, all the other are identical with embodiment one.
