When rotation, Grouting Pipe 2 is limited in lower section.Specifically, keyway 10111 is a pair, corresponding, is arranged on the outside of Grouting Pipe 2
There is a pair of of key block 201, key block 201 is square.When Grouting Pipe 2 is inserted into, key block 201 gos deep into stepped hole along keyway 10111
Inside 1011, and stepped portions are crossed, Grouting Pipe 2 is subjected to 90 degree of rotations later, key block 201 can resist the platform of stepped hole 1011
Rank component is formed self-locking.This is simple and practical in structure, is readily disassembled, and not only guarantees that Grouting Pipe 2 is not lifted in recoil, and very well
Ground solves the problems, such as difficult to tube drawing after grout cures.
Continue such as Fig. 3, the lower surface of top plate 101 and rubber mat plate 102 is set, rubber mat plate 102 can protect top plate 101 not
Deformation easy to damage.Through-hole (not indicating in figure) corresponding with stepped hole 1011 is opened up on rubber mat plate 102, consequently facilitating Grouting Pipe
2 pass through.It is influenced for grouting pressure road pavement arch camber can be best understood from, is respectively provided with pressure monitor below corresponding each through-hole
103, as shown in connection with fig. 1, pressure gauge 301 is set, the two cooperation can analyze the slip casting pressure under different road structures on grouting pump 3
The critical value of power, and effective reference frame is provided for mortar depositing construction design scheme.
Further, the bottom of shaping box 1 is provided with bracket 104, and bracket 104 is four, is respectively arranged in shaping box 1
On four longitudinal seamed edges.Bracket 104 is made of angle steel, and section is L-shaped, and bracket 104 is load-supporting part, carries entire shaping box
1 and die trial gross weight, so every bracket 104 is equipped with reinforcing rib and carries out protection reinforcing, and pass through the fixed company of bolt and nut
The mode connect is fixed with 6 phase of job platform.
Bottom plate 105 is inscribed in side plate 108, and the driving mechanism being connected with bottom plate 105, bottom plate 105 are also set up on job platform 6
It can be moved up and down along side plate 108 under the driving of driving mechanism.Preferably, driving mechanism is hydraulic cylinder 106, hydraulic cylinder
106 hydraulic stem is connect with bottom plate 105, specifically, its center for being connected to bottom plate 105.In this way, passing through hydraulic stem
Stretch the height and position of adjustable bottom plate 105, and the die trial for meeting different road structure thickness degree makes.Due to bottom plate
105 need to carry die trial weight, add so hydraulic stem end (one end for stretching out the cylinder body of hydraulic cylinder at first) also carries out reinforcing rib
Gu processing, and for preventing bottom plate 105 since ballast is deformed.In addition, hydraulic stem can push bottom after completing die trial
Plate 105 rises to limiting altitude, realizes the fast demoulding of die trial.
Continue as shown in figure 4, being provided with multiple detectors 107 on side plate 108, it is preferable that detector 107 is nonmetallic super
Detector of sound.The inside of side plate 108 is provided with the protective plate 109 for protecting detector 107.As a kind of mode, side plate 108
On offer a plurality of groove extended along 108 short transverse of side plate, the distribution of multiple detectors 107 is arranged in the groove, in this way,
Detector is located between side plate 108 and protective plate 109, and the adjustable height and position in groove of detector 107 and guarantor
It holds.
In order to real-time monitoring slurries in die trial internal flow, infiltration and compacted effect, according to die trial size cases,
Establish corresponding measurement point arrangement network, i.e. X-Y-Z three-axis reference point layout.Measuring point should meet: on 1. same surveys line
Measuring point should be evenly distributed, and spacing is identical；2. being measured due to using to survey method, so the measuring point distribution in opposite two faces has been answered
It is exactly the same；3. the corresponding measuring point of each detector 107.Detector 107 belongs to nonmetallic supersonic sounding instrument, can to die trial into
Row lossless detection, and grout distribution situation can be drawn respectively according to different time nodes.Due to detector 107 cannot with die trial into
Row contact (if contacted, will lead to the damage of detector 107), so detector 107 is set between side plate 108 and protective plate 109,
And it is embedded in side plate 108 and surveys in vertical groove.
In this example, the point layout of every one side is laterally (X-~X+ or Y-~Y+) 8, vertically (Z-~Z+)
8, totally 64 measuring points.Before carrying out grouting monitoring experiment, first it can require to survey needed for adjustment according to the industrial grade of simulated experiment
(if industrial grade requirement is lower, measuring point is without gathering, then the measuring point applied can be reduced in right amount, not used measuring point for the quantity of point
Standby mode can be entered.Conversely, then increasing measuring point (i.e. detector 107) quantity, or survey all measuring points at full capacity
Amount), and draw out structure measuring point figure.During slip casting then, there is significant change since slurries fill areal concentration, it can
By full region with shade sketch out come, and be subject to different colours differentiation, to obtain more intuitive slurries filling process figure.
In the process, the detection frequency of measuring point can be set according to demand, draw different time nodes slurries filling process figure.
The present invention can use supersonic sounding and monitor flowing, infiltration and compacted effect of the slurries under earth's surface effectively in real time
Fruit；The road analogy situation of a variety of different structure thickness degree is simulated by displaceable bottom plate, and realizes fast demoulding；It can mould
Intend different mortar depositing construction design parameters, grouting pressure, injected hole lay form.Experimental provision of the invention can be practical note
Parameter designing when slurry provides good foundation.
Above embodiments are only exemplary embodiment of the present invention, are not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
